How can you cut acrylic glass.

How to cut acrylic glass at home

To quickly and accurately cut the workpiece, you need to fulfill several rules. They “work” for most synthetic materials: organic glass, polycarbonate and others. We list the basic rules how to cut 4 mm plexiglass at home and other sizes.

  • Direct or curved cutter to make it much easier if the part is warmed up. To do this, before processing it is a little heated. As a heat source, a construction hair dryer or gas burner is used. An important point. In order not to smell acrylic, he is kept at a distance from a heating device.
  • For work it is best to choose a canvas with MP marking.S. This is hardened steel of high strength.
  • It is necessary to saw any power tool only at low speeds. Otherwise, acrylic glass will heat up from the blade and melt. The speed for each device is selected individually.
  • You can’t cut material without eye protection. We need to put on a mask or special glasses. During work, many very sharp small fragments are formed, which fly out from under the cutting node.

Direct clogging with a manual jigsaw

As mentioned earlier, if you need to save the strings on the jigsaw, then you can wet the workpiece, this will reduce friction and the process will cool. And if it is necessary, on the contrary, work faster and without effects on an plexiglass, then it must be well warmed up with an open source of fire.

In order to cut a circle, you need to draw the shape of a circle on a fake. Then start cut in the right form.

You should choose an interesting cutting option and proceed to the process.

How to cut plexiglass?

Thanks to its unique characteristics (in particular, thermoplasticity), PMMA will not be difficult to cut at home. You just need to get or get the most simple tools from Arsenal. Most often, a hand saw for metal or circular saw, cutter, milling machine is used for this task. Subtle sheets of acrylic (less than 2 mm) can be cut off even with the help of a regular stationery knife.

First of all, it should be noted that the surface of the plexiglass during cutting is heated instantly, so the surface temperature must be monitored constantly.

Cut (up to 2-3 mm)

The easiest and most common way is to use a cutter. The material must be put on a flat surface, attach a steel ruler to the cut site and several times carry out a cut on the groove.

Cut the sheet must be half the thickness of the material, and then just break off an unnecessary piece. In this way, you can cut PMMA with a thickness of up to 2-3 mm, and serious tools will come in handy for larger work.

Kryazuvka for metal

You can cut the material in a straight line with a regular hacksaw for work on metal.

However, it is worth considering the fact that the hardness of the millet is equivalent to the beech, so you will have to cut the material for quite some time and painstakingly. Acryl tends to heat up during cutting, so you will have to work slowly and constantly make sure that the polymer does not heat up.

Three.toothed disk for corner grinder

A three.toothed saw on wood copes with a sharp plexiglass. In this case, the material does not heat up and does not stick to the tool. This option is suitable for rectilinear cuts of sheets with a thickness of 5-10 mm.

Nichrome spiral

If you need to cut out a curvilineous form, then use this option. The plexiglass begins to melt already at 160 ° C, when the nichrome spiral is able to heat up to 1000 ° C and above. That is why it is necessary to have a rheostat nearby to fully control the process.

Since acrylic may burn, give an allowance up to 0.5 mm when working with a spiral, and then process the material using a grinder.

Laser cutting

The best option, of course, is to purchase a laser cut, which will provide a perfectly flat fishing line for a trimmer, a minimum waste and almost perfect ends, requiring small efforts to process. Laser cutting has several drawbacks: the high cost of buying equipment (however, you can always use the services of professionals) and the appearance of a small internal stress.

Zuker online store.By provides laser cutting service performed by highly qualified specialists. You can read more in the note “Laser cutting and engraving”.

Milling cutting

The milling machine also allows you to carry out high.quality work on acrylic cutting, but the purchase of equipment is not available to everyone. Exit. turn to professionals.

Zuker.BY offers a cutting service on the Volter milling machine, which will perform work efficiently, quickly and with high accuracy. The maximum thickness of the processed workpiece of PMMA is 24 mm. Details can be read in the material “milling cutting and engraving”.

How to glue the plexiglass?

Gluing parts from this polymer does not require significant financial and labor costs, the main thing is attentive and accuracy. Now there are a large number of different means on the market:

The simplest is the gluing using diffusion glue for acrylic Cosmofen PMMA.

One.component glue from the German manufacturer quickly fixes the surfaces from PMAA, acrylic and soxtruded profiles of parts with each other, has excellent resistance to ultraviolet radiation and thermal loads, high adhesion and low cost. The tool is used in the automotive industry, the production of window and advertising products, can be used both in external and internal work.

  • Dry thoroughly and clean the processed surface from contaminants;
  • Apply glue to one connected part;
  • Comer the elements and fix it under pressure;
  • Hold the details in one position for about 60 seconds;
  • Wait 24 hours (at air temperature 20 ° C).

If you glue everything correctly and in compliance with the basic elementary requirements, then the durable and hard seam of a muddy color will ultimately form.

Since gluing occurs almost instantly, it is necessary to use rubber gloves so as not to harm your hands.

Kryzaovka for work on metal

One of the most affordable options is to use a hacksaw. A good alternative than to cut plexiglass at home.

In its firmness, plexiglass can be compared with beech. So you can imagine how difficult and long you will have to cut the material. In addition, you will need to ensure that the glass does not heat up. Therefore, you will have to work very slowly.

It is convenient to make the markings with a marker, it leaves a bright and noticeable trace. The cutting line for the cutting of the cut is well applied with a knife, a nail.

acrylic, glass

At the same time, a hacksaw is an option on how to cut a plexiglass at home only if you have to cut it in a straight line. Fortable cuts will not be possible to perform well.

Good to know. When the canvas gets stuck during operation, pour a little water. So it will be possible to cool the fishing line for the cutting trimmer.

Cutting plexiglass at home

Cutting plexiglass at home is not difficult, as it is a malleable and easy to work material. Despite the external resemblance to ordinary glass, the operational characteristics of the organic glass are different, and it is processed by various methods: turning, strict, sawing, etc. Cut the plexiglass is permissible using a large number of devices.

Organization processing is carried out using the following tools:

Nichrome thread

Cutting by melting is carried out using nichrome wire. A voltage of up to 24 V is supplied through the reduction transformer to the wire, as a result of which it is severe heated. The nichrome thread is made by curved and curly cuts that have good surface quality and do not require further grinding.

Pets are used to cut with melting a screwdriver with a straight slot. The metal part of the screwdriver is heated by an electric soldering iron, while the end is pressed to the surface of the plexiglass. Then, holding the tool over the edge of the handle, a sheated screwdriver with a heated blade of a cutting line for a cutting trimmer. To carry out straight lines, it is more convenient to use a metal ruler or the smooth side of the hacksaw. Sequestol easily breaks along the drawn strip. details on

Circular saw or milling cutter

Circular saw or milling cutter is also a good option for working with organic glass. In this case, the milling cutter for the cutting of the plexiglass should be no thicker than 1 mm. It should be borne in mind that during cutting a saw or a milling cutter, the processed material is greatly warmed up, as a result of which it melts and foams at the site of the saw. In order not to spoil the workpiece, you need to provide cooling. To do this, use water poured into a bottle. The vessel is fixed in any way near the cutting tool, and the water is supplied to the working area using a thin hose.

The circular saw should work at high speeds. Some tools have a special mode for processing plexiglass. When working that do not require high quality cut, you can use the saw. The milling cutter is suitable for the production of thinner and clean cuts. When using a water cooling system, a smooth and smooth surface is obtained, and the cut will be transparent and neat.

Rezak

Plexigilass of small thickness is perfectly cut using a construction cutter. For this purpose, a homemade tool made of a hacksaw canvas, and even a stationery knife is suitable for this purpose.

The cut can only be made by a straight section. To do this, the line (preferably metallic) is pressed to the sheet of the material along the alleged cut, then several times with pressure is carried out with a cutting tool on the surface of the plexiglass along the ruler. Когда разрез достигнет середины слоя плексигласа, его можно легко переломить. The place of fault will be uneven and rough, so additional grinding will be required.

Scabble for metal

The easiest way is the cutting of organic glass with your own hands is carried out by a knife.haired metal. The cut lines must be previously drawn with a pencil or felt.tip pen. In the process of work, the hacksaw must be kept evenly, trying not to tilt it to the side. It is advisable to fix the workpiece hard. The surface of the cut will not be even. All irregularities and burrs are removed by a file and sandpaper.

How to cut plexiglass with your own hands at home

Cutting plexiglass at home is an event that an ordinary person is extremely rare.

Despite this, the time from the time the question arises. how to cut plexiglass? But those people who like to craft with their own hands and use this unique material in their works, very often face such a task. to quickly cut acrylic into the necessary elements.

In production conditions, some methods of cutting this material are used, at home it is more convenient and more practical to use other methods. Below, consider which methods are used not in production.

Electric

For cutting polymethyl methacrylate, an electric jigsaw is used with special files for organic glass. Jergery for plexiglass have a special marking. the letters of the Latin alphabet MP.S.

For slicing plexiglass at home, an electrolobian is often used with mp marking saws.S

acrylic, glass

During the cut, the canvas must be controlled by the speed of the tool. The more revolutions, the higher the speed of the electrician. With a high cutting rate, the synthetic polymer begins to melt. The cut place becomes white and sealed. such material is unsuitable for operation.

The feed speed and the number of speeds of the files are selected experimentally. Before cutting the working canvas, it is recommended to practice unnecessary fragments of polymethyl methacrylate.

The electric jigsaw is used to create a straight and curved cut line.

Cutting Plexiglass with a three.toothed disk

How to cut plexiglass in large volumes? Technical improvement of manual tools does not stand still. For more efficient use of corner grinder, the industry has released a three.toothed saw on wood.The three.toothed saw disk in its technical characteristics, along with wood, is also mentioned organic glass. He copes excellently with sharp acrylic for rectilinear cuts. The material does not heat up, does not melting and does not stick to the saw disc. This disk over the teeth thick from 5 to 10 mm.

How to work with a corner grinding grinder with a three.toothed saw disk, see this

In addition to corner grinders, people’s craftsmen use an electrician with special saws for plexiglass.

Peculiarities

It is important to consider that the physical characteristics of the polymer affect the power tool when cutting. Because of them, problems often arise on how to cut plexiglass at home. He begins to melt as soon as the temperature reaches the mark of 160 degrees. Bend it when reached only 100 or even 90 degrees. As a result of a slab of large thickness, it is not possible to process using a simple disk saw. You have to resort to other options.

This material has enough pluses and minuses. The advantages include:

  • high transmission;
  • low thermal conductivity;
  • resistance five times higher than that of glass;
  • environmental cleanliness;
  • stability when exposed to bacteria, moisture, microorganisms;
  • Electro insulating properties.

It is bad that acrylic is inclined to superficial damage, easily lights up, microcracks often occur in the bending places.

There are many tools on the market that allow you to make an even cut.

Laser

The most convenient method of sawing acrylic is a laser. However, this method cannot be applied at home, it is used exclusively in industrial production.

A thin laser allows you to make accurate incisions and cut even the smallest details of the future structure or product. If necessary, you can contact a specialized workshop or an enterprise that is engaged in the production of organic glass and products from it. It is recommended to make drawings in advance and mark on the polymethyl methacrylate canvas.

The laser allows you to carefully chop and plexiglass even small parts, is used only in industrial production

How to cut a circle

If, without thinking of grabbing this business, then it is unlikely that something from this will come out.

After all, a very peculiar material was organized:

  • It heats up quickly and contributes to the breakdown of the tool;
  • If it is rude to handle it, then it can crack;
  • In order not to break the strings of the jigsaw, you need not to influence the force;

All these properties indicate that cutting a circle from this plexiglass is not so easy. Before starting the cutting process, it is necessary to process the material.

These processing methods are for plexiglass, whose thickness is about four millimeters, but not more. There are also ready.made knives for acrylic. They will help a person in marks and in difficult areas will help to solve various problems.

Such a device can be sawed up to one centimeter of plastic. Also, this method will save a very large amount of time and will make cutting in sufficiently large quantities.

With the help of an electric jigsaw, you can also produce a large amount of work, only in this case it will be more convenient. You can use wood files. Just do not need to develop high speed, otherwise the device may fail.

Additionally: Miracle Lobzik for artistic sawing

But you need to remember that if the teeth are large, then such files will not go. Very small teeth are needed, and the speed of cutting should be the smallest.

In order to cut a circle, you need to draw the shape of a circle on a fake. Then start cut in the right form.

You should choose an interesting cutting option and proceed to the process.

Cutting with a nichrome spiral

When using a nichrome spiral, it must be remembered that the melting point of acrylic glass is about 160 ° C. Nichrome spiral heats up to 1,000 ° C. Therefore, to regulate the temperature, you must have a rheostat or a set of resistance.

  • Remember the acrylic glass burns. When processing using a nichrome spiral, it is necessary to give an allowance of 0.2-0.5 mm and then bring the parts to the required sizes manually;
  • Acrylic glass is perfectly polished with all the numbers of grinding skins.

There are two options for using a nichrome spiral:

How To Cut Plexiglass The Easy Way

Rectoline cutting of organic glass by nichrome spiral

For these purposes, any reduction transformer of direct or alternating current is suitable.

Acrylic curvoline cutting device

Even a welding machine on minimum currents will give the necessary heating temperature. The main thing is to adapt to the speed of the spiral penetration into acrylic. Wood burning device is also suitable for these purposes.

Briefly about milling

Preparation for milling consists of several stages:

  • Creating a file with the required part in vector format.
  • Adjustment and uploading to the machine of this file by the CNC operator.
  • Fixing the workpiece on the desktop.
  • Launching the machine.

how to cut plexiglass

The process of milling processing consists of many passages of a cutting tool (cutter) on the workpiece. The number of passages depends on many factors, such as: the thickness of the workpiece, its hardness, type of cutter, type of processing (black or finished), frequent cases of milling of the workpiece, leaving allowances that are cut into one passing at the finish stage of milling.

Milling is used where the high accuracy of the resulting product is necessary and when it is impossible to achieve the desired result in another way of processing.

Due to the work of the cutter, you can perform the following tasks:

MK how to cut an organic glass of 10 mm. (and thicker) quickly and evenly.

How to cut plexiglass?Up to 1 mm. It is enough to make an incision on one side. A paper knife.From 1 mm. up to 2.x (2.5 mm) incision on both sides.But 3 mm. you can’t cut it out with a knife. Surzaks are used. hooks made of filled steel. On the photo ; from above the cutter from the saw blade, below. From the file.

Millet.glass with 10 mm thick. (and wider) in principle, in principle, you can smash.T.e. 2 mm. On each side and try to break. But it will be crooked, not beautiful and terrible tiring. And if the thickness is 20 mm? You can cut with a hacksaw. will be more curved and no less boring.Therefore, boldly put an object for a circular saw. Pay attention to the “teeth”.

Feel free to put a plexiglass under the saw and. Cut the desired size. It’s all about the disk feed. If too fast. Such teeth, of course, will smash an organic glass or leave the burrs at the edges that “is not a grain of grains”.If too slow. plexiglass will begin to melt and stick to the disk.Without rushing, smoothly, without effort, we serve the saw and get “very karacho”.

Wipe the traces of the saw on fine sandpaper. Akhtung! Fighting sheet should be even t.e. not twisted into a tube, otherwise you will fill the edges.

The plane very quickly became smooth, but not transparent, but matte.That’s why. Three further on the “microns” (zero).

The plane has become almost transparent and if wiped with oil, maybe so it will go. But we do not need “and so will go away”? We polish on the felt circle with the paste of goi.If someone does not have such a circle (and you do not have it) you can simply rub with a piece of felt or on a piece, and if it is completely trouble, then you can do without pasta. Only more time will leave.

This is what happened as a result. Width of organic trigger 60 mm. (6 cm). And the book lines can be seen perfectly.It took everything for about 20 minutes. not more. This is taking into account the fact that I am the “brake” incredible and take everything to a turtle step.

Interesting effect (photo without flash). The line “grabbed” from the page and “took out” by 6 cm.Probably somewhere can be used. I just don’t know. where?

Using a hacksaw or other similar tool

In this case, almost any saw can be used, most often in this capacity is a hacksaw for metal, jigsaw or other similar tool. With such a cutting method, it should be borne in mind that the plexiglass has poor thermal conductivity and the heat itself melts the material that is released at the site of sawing. The result is often the cutting of the cut after passing the hacksaw.

Read how to cut plexiglass at home

To avoid this, they often use water to cool the cut site.

You can greatly facilitate the work using the power tool (electric saw, electrolobian or angular grinder). For better cutting quality, the tool should work at high speeds. How all work is done, shown here:

Useful tips

There are some tips on how to cut plexiglass without chips. To achieve a pure cut, leave acrylic for a while over a gas burner.

Another option: you can use the simplest lighter. True, you will have to spend much more time.

With the help of an electrician, you can cut out a plexiglass. Take narrow saw canvases.

When you purchase them, find those on which there will be a designation mp.S. These are the most effective devices to solve the problem than cutting off plexiglasses.

During work, follow the speed of the tool. The number of revolutions depends on this. In practice, the speed is selected experimentally. The most important thing is that the plexiglass does not begin to melt.

Be sure to put a protective mask on your face. This will protect themselves from fragments, which during cutting will fly at a huge speed.
