How to cut MDF?

MDF cutting

should be carried out on specialized format-cutting machines with circular saws, at a low feed speed. Otherwise, deep marks from unevenly spaced saw teeth will remain on the end sides of the parts, which will be clearly visible after the PVC film shrinks.

Rules for cutting chipboard, features and recommendations

To cut laminated chipboard you will need the following tools:

hacksaw;
sawing machine;
milling cutter;
Circular Saw;
tire;
electric jigsaw.

You will also need additional equipment for sawing:

Ruler and pencil;
masking tape and tape;
sandpaper.

Cutting laminated chipboard is carried out in the following order:

Marking the material. To mark the blanks, a ruler and a pencil will be needed to mark points on the sheet of material from the end. Then you need to connect the dots evenly in one line and stick masking tape on top. A good way to saw laminated chipboard without chipping is by using tape, as it helps reduce the number of cracks in the sheet material that occur due to elevated temperature and strong pressure. Cutting laminated chipboard.
Next, sawing of the chipboard occurs. We choose what to cut the chipboard with and place the tool at the required angle so that the sawn edges of the sheet are even. Cutting laminated chipboard and MDF should be done very carefully and as smoothly as possible.
Slab processing. If sawn chipboards at home are uneven at the ends along which cutting was carried out, they are processed using a belt sander. In some cases, it is better to immediately contact companies that provide services for the production of custom-made furniture parts according to the customer’s dimensions and cutting laminated chipboard using special equipment. To paste over the edge of a part, a special end edge is used for processing.

You can also use a regular glass cutter

The easiest way is to use a conventional roller glass cutter. It is used for small amounts of work. The cutting line is marked with a pencil using a ruler. A glass cutter is used to make a shallow furrow along the intended mowing line. The break occurs by gently pressing on the edge of the tile placed on the corner of the countertop. The edge of the cut obtained in this way has noticeable irregularities and requires additional processing with abrasives. It is generally accepted that this option can only be suitable for thin wall tiles, and cutting floor tiles is unlikely to work. Many craftsmen believe that it is impossible to cut porcelain stoneware with a regular glass cutter.

What else do you need to know?

When you plan to saw off everything without chipping on one side, it is permissible to use files with both upper and lower teeth. Most craftsmen prefer small files with straight teeth. Such devices chip less material, but still work quite well. After cutting, it is best to process the ends with emery stretched over even bars. If you don’t have a ready-made crayon of a suitable color, you can mix different crayons, like paints in an artist’s palette, and get a new color.

In order to cut without errors and, moreover, quickly, you must always take into account the company markings. There is no generally binding standard for markings yet, but almost all companies strictly follow the classification developed by Bosch specialists. Or at least they list it along with their own abbreviations and terms. CV saws (sometimes referred to as HCS) are well suited for cutting wood and wood-based products.

Some inscriptions indicate in which mode the tool works optimally:

basic - a simple blade that allows you to make a clean cut of high quality;

speed - a device whose teeth are set apart (this allows you to cut faster);

clean - a blade that has not been cut (usually gives the cleanest cut).

If the workpiece is relatively thick, it is preferable to have a saw blade with large cutters that are not set apart, then the deviation from the vertical will be minimal. A longitudinal (relative to the fibers) incision is most often made with helical saws. For a transverse one, a straight blade is better suited. When you plan to make a piece of furniture, it is advisable to choose a less productive, but more accurate tool. Since most saws produced today cut the material as it is pulled in, the workpiece will need to be processed from the inside out.

Installation of slabs

At first glance, installing MDF boards seems very difficult. But the design is as easy to assemble as a regular children's puzzle. The connection of the panels is the same as for PVC: using tongues and grooves. One side of the panel will be pointed and the other will be bifurcated. Therefore, by inserting the tip of the panel into the groove, you will get a prefabricated structure.

If the panel will be attached to the wall, then it is necessary to equip the sheathing. MDF does not like moisture. The air gap will allow air circulation. Moreover, it is best to make the sheathing from wooden planks. Attach the panels to them with glue or mechanical fasteners.

As already noted, the panels can be installed with glue. This is the most common and simplest option. “Liquid nails” are used, which must be applied in a thick layer from the reverse side to the MDF board.

This method is suitable for flat surfaces. Moreover, the glue consumption is very high. You can also use staples as fasteners. Also an inexpensive option. In this case, a construction stapler is used.

Any home craftsman sooner or later is faced with the need to cut chipboard. This could be making furniture with your own hands or covering walls with MDF or chipboard panels. As you know, sawing chipboard is not difficult, but making an even cut without chips is not an easy task.

Molar knife

The simplest tool for cutting PVC. But for an unusual kitchen or shoemaker, all you need is a molar knife.

Its blade, while new, is very thin and sharp. And when it gets dull, the blade can be replaced instantly. By biting off a piece or inserting a new one. An ordinary knife is inconvenient and cannot be sharpened quickly. Also, it won't be as thin.

The molar knife is limited in its capabilities. You can only cut the panel lengthwise with it. Of course, you can try to make a cut across. But nothing good will come of this.

How to cut panels lengthwise? This is difficult to explain within the scope of this article. However, the basic principle can be described.

The blade extends a short distance of 3 mm.

From the back side of the panel we select the place where the cut will be made.

Then we cut out a strip, from edge to edge (we are talking about the internal edges of the panel). A cut is made near the rib, then another cut is made near the adjacent one. We make cuts along the entire length.

A strip of plastic falls out and a groove forms.

Then, on the same back side, you need to make a shallow incision near the desired rib. And break the body over it.

The molar knife has the advantages of being fast, quiet and simple. Its disadvantages are that the panels can only be cut lengthwise.

Tools that can be used to cut panels

As already said, MDF panels are an excellent facing material. Most often they are used to decorate an office, loggia, hallway, or corridor. They can be used to mount not only walls, but also ceilings.

They go well with wooden or plastic lining and tiles. Experts do not recommend using such boards in damp rooms, as moisture will cause the wood to swell. A variety of equipment is used to cut MDF boards.

Many people recommend cutting slabs with a jigsaw. This tool is suitable when cutting will be done indoors. Then you can connect a vacuum cleaner to it. The result is an even cut. If something happens, you can trim it with sandpaper or a scratch pad.

The main thing is to make neat markings before sawing the slab. To do this, use a corner, ruler, tape measure, laser level or regular level.

Cut any sheet materials without chipping. Plywood. Chipboard. laminate

You can also cut MDF with a hacksaw. Such a tool cuts carefully and accurately, but very slowly. Therefore, it is recommended to use a hacksaw when you need to adjust something. A grinder will cut a slab much faster.

The cut is accurate, but during operation the tool generates a lot of dust. It is best to work with an angle grinder on the street, or when the house is undergoing major renovations.

Hello everyone. I recently bought a MODULAR kitchen. I decided to have it assembled first by an assembler. But there the deadline was almost in November. I decided to assemble it myself. Everything was clear with the modules and closers and hinges. But there were problems with the apron. I’ll tell you right away when I bought the kitchen I decided to buy it from plastic. I understand that someone will say buy MDF or glass and less hassle*, but at that time the budget was limited. I have a straight kitchen. And here’s the moment: how or what should I decoratively cover the cut of this plastic in the corner by the sink?

Where they gave me the strips - 2 pieces for the end and 1 for the corner. But they are 4 mm inside and the plastic of my apron is 1.5 mm. I called the assembler and asked. He says I have never assembled something like this with such an apron.

I searched all over YouTube and nothing is written about the joint of an apron made of ABS plastic. I would be grateful for any information on the planks and installation.

Jigsaw

This tool can be called the main one. A jigsaw is good for everyone and has a minimum of disadvantages. Panels can be cut lengthwise and crosswise. You can cut shapes with ovals and other broken things.

The jigsaw has a special feature. It tears the edge of the panel in places where there is very little to cut. At this time, very often the panels burst (especially in cold weather).

Therefore, it is worth using a file with a minimum tooth. For ourselves, we chose a Bosch metal blade with a 0.8 mm tooth. This file will protect you as much as possible from a torn cut.

If the jigsaw operates at high speeds, you can cut with such a file very quickly. This file is for metal and does not become dull when cutting plastic products.

The main advantage of a jigsaw is its versatility. You can cut PVC panels lengthwise and crosswise. In any spatial position.

The downside of a jigsaw is its weight and the presence of a wire. If the blade is chosen incorrectly, the cut will be torn.

There is one secret

When you have to prepare a lot of frame-sized sticks. For example, you need to cut 20-30 pieces at once.

And so as not to cut one thing each time, but to increase the speed. You can resort to one secret.

You will need clamps (presses) as in our photo. Take several at once, usually 5 pieces. Adjust them so that they do not stick out from each other and clamp them with presses. Two pieces on each side of the panel.

And cut quietly. In this way you can cut up to 5 panels at a time. You can cut more, but the Bosch file does not allow this.

You will speed up the cutting process five times and make your work easier.

Selection and installation of extensions on interior doors in 4 options

Remove the fabric from the hinges and free it from the fittings (handles, hinges, other protruding elements).
Place the canvas on a workbench or flat area (table), securing it with clamps. It is necessary to ensure complete immobility.
The doorway and leaf are carefully measured to determine the optimal cutting location and the degree of shortening. Marking is being done.
The place for the cutting tool to work is being prepared. When working with a circular (circular) saw, a board is secured below the cut point. If a grinder is used, it is recommended to provide a stop on both sides of the cutting line.
If there is veneer, it is carefully cut with a knife along the guides. If there is a varnish coating, then to prevent it from cracking along the cutting line, the varnish is removed with sandpaper.

Jigsaw

The most versatile tool that can be used to cut plastic panels in any direction, along a curve, in a circle is an electric jigsaw. We had one, but it turned out to be completely unusable due to the lack of suitable files.

Plastic is a dense material; you need to saw it with a blade with very fine teeth so as not to tear the edge. There are special files for plastic, but those designed for metal are also quite suitable. We only had wood.

The smaller the width of the canvas, the easier it is to make shaped cutouts, for example, for a socket or lamp. A jigsaw is also suitable for simultaneously cutting a pack of 3-5 panels, if its thickness is less than the length of the file, and the power of the tool is sufficient for such work.

Expert opinion

Strebizh Viktor Fedorovich, leading construction foreman

MDF can be of different thicknesses; a thin MDF board up to 3 mm thick can be cut with a knife; thicker boards are best cut with a saw. If you want to clarify something, please contact me!

Ceramic cutting options

Each of the methods is good in something different and suitable in one case or another. How to cut ceramic tiles? There are three main ways to cut ceramic tiles evenly:

Using a grinder with an appropriate circle.
Use an electric, manual tile cutter or special nippers.
Handy tools for cutting ceramic tiles, such as a glass cutter, a well-sharpened nail or a drill.

In order to understand all the intricacies of the work, you need to consider each option in detail.

Universal cutter

The universal cutter is called by different names. It has many manufacturers. When we bought our tools, one of the leading manufacturers was Bosch.

The tool is not cheap. But once you buy it, you won’t be able to get by with anything else.

The cutter, unlike all other tools, makes oscillatory movements.

We mainly use two main types of files: wide - 25mm*40mm and narrow 10mm*20mm.

Very often during installation, you need to cut the PVC panel in place. Often this can only be done with a Bosch cutter. It is impossible to get into difficult places with any other tool.

The cutter greatly simplifies the work and speeds it up. Wall products can be cut lengthwise and crosswise. You can even cut off the top or bottom layer of the panel.

Let's talk about the cons. The price of the tool and its consumables is off the charts. For example, a file for a jigsaw will cost 100 rubles, and a file for a cutter will cost 800 rubles. Files quickly become unusable.

Safety precautions

Regardless of which tools you decide to use, the above tips will help you avoid the mistakes of most inexperienced decorators and create a cozy interior that will delight you for many years.

Which is better: heated floors or radiators?

Warm floorBatteries

Not every grinder is suitable for cutting panels. It should be small so that you can easily hold it with one hand. You won't be able to use a large grinder.

The thinnest disc of 0.8 mm, 1 mm or a maximum of 1.2 mm is installed in the grinder. The disk used is a regular one for metal.

The grinder gives an amazingly even cut, without nicks and, as people say, “snot.”

The grinder does not tear plastic. It doesn't matter what part of the panel you cut and in what weather. Both in cold weather and in hot weather - using a grinder, you will get an even cut.

Using a grinder, you can cut literally millimeters from a wall panel.

The disadvantages include the fact that it is heavier than a jigsaw, and even more so a knife. But the biggest disadvantage is that the grinder produces a lot of fine dust. It gets everywhere.

Expert opinion

Strebizh Viktor Fedorovich, leading construction foreman

Installation of MDF may seem complicated only at first glance, in fact, the entire structure is assembled similarly to a children's construction set, and even someone who has never picked up a tool in their life can radically change the situation. If you want to clarify something, please contact me!

Arch finishing

Arch design often becomes a problem. In general, there are not many external corners in the apartment, but there are always some on the arch. And in the aisle they very often get touched. Either furniture, or other cargo, or simply a resident who did not fit into the opening. And there are no questions with the straight part, but the rounded part can be a problem.

And not only in the doorway can there be an arched vault

In general, you can use universal corners for an arch. They are flexible, which is very convenient. There are flexible, non-universal ones - plastic, made from a special polymer with increased elasticity.

But in general, corners with different shelf widths are used to decorate arches. They are even called arched. They have one shelf 10 mm (external) and the second - internal - 30 mm or more. They bend easily. You can’t twist it into a donut, but it’s not difficult to get an arc of any curvature. You just need to use a secure hold while the glue dries.

This is an arched plastic corner

If you want to bend a regular corner, you can do this by heating the plastic. For this work you need a hair dryer. The usual one - for hair - will not work, since its temperature is too low. We also need a template according to which we will bend the plastic corner. Take a piece of fiberboard, tighten screws or drive nails, forming the profile that you require.

This way you can decorate the corners of the arch with protective corners

They start bending from the middle. Warm up the area, constantly pressing on the middle, and using a hairdryer, moving from the center to the edges. So you need to bring the corner to the desired curvature and leave it in this position to cool. To prevent it from straightening out, holes are made in parallel with a row of screws for the second row. The distance between the rows is equal to the width of the corner shelf. After the plastic has bent, insert and lightly tighten the screws. After the plastic has cooled, remove them.

Cutting with improvised means

It is not always necessary to do a large amount of work. Why waste money if you need to cut several tiles. In this case, you can use the following tools:

ordinary glass cutter;
sharpened nail or drill;
assembly or stationery knife.

Important! It is recommended to use a drill bit with pobedite tip. Thanks to it, you can better apply a deep scratch to the surface of the ceramic.

How to cut ceramic tiles with a glass cutter? The algorithm of actions is as follows:

The extra fragment is measured.
Markings are applied to it.
A metal ruler is placed along the length of the fishing line. It is important to do this perfectly evenly.
All that remains is to use a glass cutter or other sharp material at hand once along the ruler. During the process, the ruler should be held well. The result will be a noticeable scratch.
The tile is placed on the edge of a table or workbench. The scratch on it should coincide with the edge line of the table.
With a strong, confident and sharp movement of your hand, press on the edge of the tile.

The required piece will break off. It is clear that it will not be possible to make a perfect cut. But you can save money. And after that, it’s enough to rub the cut with sandpaper. In addition, if you put the tiles in clean water for just an hour, the cutting process will become better.

Note! Some people ask whether it is possible to cut ceramic tiles with a jigsaw. Yes, but the cut will not be as high quality as we would like. The use of an electric jigsaw is rational when adjusting tiles laid in an inconspicuous place. But, there are special diamond-coated saws for manual or electric jigsaws. This option is allowed.

Figured breaking out

Sometimes it is necessary to make curves in the mowing line. The mowing line can be not only straight, but also semicircular. Such breaks are more problematic when they do not start from the edge. In such cases, you will have to first make a hole and then break it out.

For figured breakout, it is recommended (if possible) to apply a deep mark along the entire breakout border using any method. This will reduce the number of possible chips.

Figured breaking out of tiles.

There is a special tool for breaking out - pliers with a wheel. But for one-time work it is not advisable to purchase a special tool. Therefore, you can get by with ordinary pliers.

The breaking technology is very simple. The pliers (or tongs) are strongly compressed, causing the material to crumble, or they are compressed and sharply turned (only far from the cutting line, at least 5 mm). Small pieces break off. If you try to break off a large piece at once, you can ruin the whole job. A part may break off behind the line of marks.

Long, straight, narrow pieces across the entire tile are broken off by sharply turning the pliers to the side. Preliminarily clamping them along the mowing line marks (a scratch, of course, must be caused). In this case, the entire length of the tile may not break off and the procedure will have to be repeated on the remaining part. Then the remaining sharp protrusions are also carefully broken off.

The simplest way is to apply a mark and hit it on a sharp corner. In this way, you can easily and quickly prepare most of the elements.

Cutting the additional frame along the narrowing. The easy way

Calculation of material quantity

The installation of MDF, like any other material, must begin with a preliminary calculation of the number of panels. To do this, first of all, determine the area of the room: all the necessary measurements are made, and the perimeter is multiplied by the height. It is also important to consider the presence of doors and windows in the room. Their quadrature is calculated in a similar way, multiplying the height by the width, the resulting result is subtracted from the total area of the room.

Then, knowing all the numbers, you can go shopping for wall panels. Since the products are sold in different sizes, you will have to additionally calculate how many square meters are in each slab. Usually manufacturers write this on the packs. If, for example, a panel with a width of 900 mm and a length of 2600 mm, then it is enough to multiply 2600 mm by 900 mm. As a result, it turns out that there are 2.34 m2 in one slab. Then the area of the room that is planned to be covered must simply be divided by 2.34 m2, and you will get the required number of panels.

Methods for cutting laminated chipboard without chipping

Sawing of laminated chipboard at large woodworking enterprises is carried out on a special format-cutting machine. Small workshops that produce furniture also purchase one, but it is expensive, therefore, it is not practical as a household tool. If the question arises of how to cut laminated chipboard without chipping, then as an alternative cutting method, you can choose sawing using a hacksaw, circular saw, chipboard cutter or jigsaw.

Using a hacksaw

Sawing chipboard without chipping with a hand saw is not as easy as sawing laminated chipboard with a jigsaw. Although this is a cheap and accessible way.

First you need to cut the cutting line with a knife, draw it with a nail or an awl, and then stick on masking tape to protect the top laminated layer. Then, at an angle of 30 degrees, carefully, without pressing too much, cut the material. The selected hacksaw file should have fine teeth so that the cut is as even as possible.

A hacksaw can leave damage, which can be eliminated by using a belt sander set perpendicularly for subsequent edgebanding.

At the final stage, it is worth treating the cuts with fine sandpaper and covering them with a flexible profile.

Jigsaw

Often a jigsaw is used to cut laminated chipboards. The main condition for accurately cutting a slab is small teeth.

A jigsaw cannot replace a circular saw, since it is mainly used as a cutting tool for small areas of slabs. They need to work without strong pressure, smoothly and not too fast. If the laminated chipboard sawer is inexperienced, small chips may appear on the reverse side, but with practice the quality and appearance of the cut will improve.

Circular saw

If the question arises about what to use to cut chipboard and which tool to choose, then a circular saw is quite suitable. It is also often called a circular saw. This is a disk tool mounted on a table. Many people are interested in which circular saw blade to use. You will need a circular disc with fine teeth. The cutting quality is better than when using a jigsaw.

For greater accuracy, it is worth marking the guides, and also not working at too high speeds.

Using a router

The router is used not only for cutting slabs, but also for drilling holes, cutting grooves, creating edges, etc. It can be used to make figured cuts. The tool is used in conjunction with a jigsaw. The slab is first sawed with a jigsaw, and then a cutter with a bearing is used, which gives the cut the required depth. Professional sawmakers know how to drill, cut and saw slabs with a router. Using this tool, the cut is absolutely smooth and neat. However, this is a very labor-intensive process that requires increased attention and special skills (for example, placing a template for a cutter on the drilled or other surface), a process that without experience, it is better not to undertake such work, but to order cutting to specialists. Some workshops provide this service. The main supplier of wood cutters is the Topvoltage company; when ordering a tool from them, you can also have it delivered.

Cutting to format using a saw

The use of a sawing machine guarantees accurate cutting and complete absence of chips. Such machines are used in production and are considered specialized equipment.

Its main components:

Carriage. Allows movement of the movable table, but the plate is fixed in the desired position.
Saw unit. It has two flat metal disks: the first one does preliminary sawing, the second one does final sawing right through.
Bed. The mechanism rests entirely on it. Eliminates vibration and adds stability, which is important for the quality of the cut.

Three desktops: 1st: node location. 2nd (movable): feeding slabs for cutting. 3rd: maintaining the sawn parts.

Types of sawing machines depend on the time of continuous operation:

light – 5 hours;
medium – no more than 10 hours;
heavy – no more than 20 hours.

When setting up the machine, the following matters: depth of cut; plate position; cutting angle.

The cutting occurs as follows:

the plate is fixedly fixed to the table (movable carriage);
the workpiece is positioned according to the size ruler and the saw unit is started;
when the disk reaches the required speed, the table will move forward along with the workpiece plate and fall on it.

The use of format-cutting machines is advisable for mass production, and not for isolated cases. For one-time independent use, you can choose a simpler tool or order cutting from specialists.

Sawing with undercut

Cutting with trimming is performed as follows:

tire - the ruler is fixed to the plate using clamps on the marking line;
a cut is first made along the line on one side with a depth of about 0.1-0.3 cm;
then, on the other side, the slab is finally cut through.

If everything is done carefully, no chips will appear.

Do it yourself or order it?

High-quality sawing of chipboard is difficult to do manually due to the large size of the sheets. The dimensions of a standard slab are 2440x1200, and this is not the limit. However, if you work with chipboard or MDF quite often, it makes sense to get an expensive tool and work for your own pleasure. If you only need to cut a few sheets, you can go two ways:

Cut the slabs yourself using available hand tools;
Order cutting of chipboard in a specialized workshop.

What to choose is up to you, and we will consider each of these options.

Re: Processing MDF and plywood edges at 45 degrees

The body is quite easily assembled from parts sawed at 45 degrees with hand tools, for example, a Festulov 55 rail saw. No cracks or anything else. Moreover, not just MDF or plywood, but veneered MDF with a veneer thickness of 0.6 mm. And if it’s just bare MDF or plywood, then there won’t be any problems at all, the finishing will hide the defects.

Moreover, with this assembly option, the seams and joints will not come out over time, as in a simpler version with a 90-degree edge, putty, etc.
