Sawing chipboard without splitting: How and with what to saw chipboard without splitting?

Sawing panels of chipboard and other materials

This is especially important when sawing panels with a double-sided surface finish. It is possible to cut fiberboard at home with an electric or hand saw

Of course, the saw has to be sharp, with a fine tooth, the jigsaw should be set to the maximum speed. Place the fiberglass horizontally on a support that should not interfere with the sawing (between two tables or chairs, for example), secure it, if necessary, with clamps

It is possible to cut fiberboard at home with an electric or manual jigsaw. Of course, the saw blade must be sharp, with a fine tooth, on the jigsaw should be set to maximum speed. Put the fiberboard horizontally on the support, which should not interfere with the sawing (between two tables or chairs, for example), fix it if necessary, using clamps.

Electric jigsaw should be held with both hands, pressed tightly to the surface, move smoothly, strictly along the mowing line of the marking, without jerks and pressure.

The same applies to hand jigsaw work.

In the case where you need to cut a lot of sheets of material, it is more convenient to contact a specialized firm. This will save you time and effort.

Choice of circular saw blades and saw blades

When cutting, cleanliness and speed inverse proportions. It is worth noting that the shear chips will appear in any case, so the main objective is to reduce their size to a value where they can be easily eliminated by subsequent processing. the smaller is the size of the chipping, the smaller is the tooth size and the closer to a right angle at which the cutting edge touches the material surface. For selecting a circular saw blade, these are the two most important factors of the three.

The third is the size of the set Offset of adjacent teeth, which can be simply determined by holding a ruler against them. To ensure a clean cut the setting should be minimal, but do not forget that in this case, when trying to cut a thick board or sheet of plywood disk can banal clamp or the end face will be burnt from the friction.

Jigsaw blades are more varied. For splinter-free cuts, there is a clean-cutting saw series, e.g. BOSCH has a line of blades called CleanWood. The main difference between them the small size and the lack of teeth directionality. They are usually shaped like an isosceles triangle and cut in both directions of movement.

Also saws for clean-cutting are characterized by the almost total absence of reaming and opposite sharpening direction of adjacent teeth. In order to be able to make curved cuts, the width of the blades is very small, which makes them rather fragile.

Blades that are designed to work on metal products can also be used for fine cutting of sheet metal. These saws have the smallest known tooth size, so the cut is slow, but with the highest quality. Due to the large width of the metal saw blades, a clean curved cut is only possible with a large bending radius, on average about 6080 cm.

Note also that the blunting of the teeth, which is typical for low-quality saws with mileage в 35 meters, also leads to splintering. So do not skimp when buying consumables if quality of processing is really important to you.

Once the saw has been selected, it is still necessary to saw the laminated board correctly at home. Experts recommend to saw along the rail (the rail clamped in the clamps will do). If you use a new, unworn blade, you can cut particleboard as cleanly as with a circular saw. It is advisable to run the jigsaw at the lowest rpm possible. This will significantly increase the life of each saw used.

The blades themselves are placed at right angles to the jigsaw blade. The easiest way to check the angle with a square or protractor. Important: the straight line through the cutting edge of the tool must be parallel to the rigidly fixed part of the jigsaw. The use of special inserts is recommended, reducing the likelihood of splintering. But to make them work more effectively, they usually notch the laminate layer on the side where the blade will exit.

Sawing chipboard without splitting

The sawing of chipboards in large woodworking companies is performed with a special panel sawing machine. Small workshops that produce furniture, also acquire this, but it is expensive, so as a home tool is impractical. If the question arises, how to saw chipboard without chipping, then as alternative methods for cutting you can choose sawing with a hacksaw, circular saw, a cutter for laminated chipboard or with an electric jigsaw.

Using a hacksaw

It is not as easy to saw chipboard without splitting with a hand hacksaw as it is to saw chipboard with a jigsaw. Although this is a cheap and accessible way.

First you need to cut the cutting line with a knife, run a nail or awl, and after that put a masking tape, to protect the top laminated layer. Then at an angle of 30 degrees carefully, without pressing hard, cut the material. The selected saw blade of the hacksaw should have fine teeth, so that the cut was as even as possible.

The hacksaw can leave damage, which can be repaired with a belt sander, set perpendicularly, for subsequent edging.

The final step is to sand the cuts with fine sandpaper and close with a flexible profile.

jigsaw

Often an electric jigsaw is used for cutting laminated chipboards. The basic condition for neatly cutting the board is a small tooth size.

Jigsaws are no substitute for circular saws. к. it is mainly used as a cutting tool for small areas of panels. It should be used without much pressure, smoothly and not too quickly. If the chipboard cutter is inexperienced, small chips may appear on the back side, but with practice the quality and appearance of the cut will improve.

Circular saw

If there is a question of what to saw chipboard with and what tool to choose, then the circular saw is quite suitable. It is also often called a circular saw. It is a circular tool fixed on the table. Many people wonder which circular saw blade to use. A circular saw blade will be needed with fine teeth. The cut is of higher quality than with a jigsaw.

For greater accuracy, it is worth marking the guides, as well as not to work at too high rpm.

Using a router

Milling machines are used not only for cutting boards, but also for drilling holes, cutting grooves, creating edges, etc. п. It can be used for shaped cuts. tool is used together with a jigsaw. The board is first cut with the jigsaw, and then a cutter with a bearing is used to give the cut the desired depth. Professional sawyers know how to drill, cut and saw panels with a router. Using this tool, the cut is perfectly flat and neat. However, it is very time-consuming, requiring increased attention and special skills (eg, alignment of the template under the mill to be drilled or other surfaces), the process without any experience is better for such work on its own do not undertake, and order the sawing specialists. This service is available in some workshops. The main supplier of wood milling machines is the company Topvoltage, ordering from them the tool can be done with delivery.

Circular sawing machine

Use of sawing machine guarantees neatness of cut and absence of chips. These machines are used in production and are considered to be specialized equipment.

  • Carriage. Allows movement of the sliding table, but the plate is fixed in position.
  • Saw unit. Has two flat metal discs: the first makes a precut, the second makes a final cut through.
  • Stand. It completely supports the machine. Eliminates vibration and adds stability, which is important for quality of cut.

Three working tables: 1st: positioning of the assembly. 2nd (mobile): feeding of boards for sawing. 3rd: Supports your cut.

How to clean cut Conti board

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

Cutting depth, plate position, and angle of cut are all important when setting up your machine.

  • The plate is fixed to the table (movable carriage);
  • The workpiece is positioned on the dimensional ruler and the sawing unit is started;
  • When the disc picks up the desired speed, the table will move forward with the workpiece plate and hit it.

The use of panel sawing machines is practical for mass production and not for individual cases. For one-time do-it-yourself use you can choose an easier tool or have it cut by a specialist.

Sawing with undercutting

  • bar. the ruler is fixed to the board with clamps on the marking line;
  • the line is pre-cut on one side to a depth of about 0.1-0.3 cm;
  • Then on the other side the slab is cut definitively through.

If everything is done carefully, no chips will appear.

Causes of chipping

If you observe the process of chipping, then you can find a pattern. when you cut from the bottom, the saw blade teeth do not finish sawing the material, and do not get chips when leaving the material.

If the process is carried out from the bottom upward, the teeth snag, and a break is produced. Fibers in wood begin to cling to the material, and if you cut the laminated chipboard, you get splinters and the coating deteriorates. If you try to cut two layers of laminated chipboards at the same time, the layer underneath will be very well sawn, because the layer on top will counteract the appearance of chips.

Note that the option “soft start” helps to increase the accuracy of processing, when the electric jigsaw gradually begins to gain speed, and the cut will occur as it should be. The tool will go slowly, and you should keep a visual check on the cutting point and the marks.

Choosing the right chipboard sawing: chipboard sawing without splitting, machine with your own hands

Particleboard (chipboard), and in our time, mostly laminated (LDPE). one of the main materials for the manufacture of affordable furniture in the home workshop. This board is made of coniferous and deciduous wood materials, so it has qualities such as strength and ease of processing. But if not properly cut, chipping of the material is possible. That’s why you should find out how to cut chipboard correctly before making furniture.

For this purpose, you can even assemble industrial equipment. a nesting machine.

Circular saws

The most suitable tool for cutting boards and pressed materials of different thicknesses. The cuts are precise and several parts can be stamped.

Professional machines are used for industrial purposes.

They are small and lightweight (up to 20 kg), easy to install. The machine can be removed and relocated as needed. the tool is suitable for sawing up to 8 cm in depth. Also in the home workshop, you can saw a tabletop with a circular saw with an extended working table.

Household machines are often used in the home.

They are more convenient than household machines, because they allow not only longitudinal but also cross cutting. The maximum cutting depth is 9 cm. Exact marking and safety precautions must be taken at all times.

Precision and quality

MDF and chipboard panel cutting machines have a high quality of cut so that the subsequent expenses for the following operations (sanding, deburring, removal of chips and burrs, etc.) can be reduced. That’s why they can make cuts of any complexity and configuration, meaning almost limitless possibilities in furniture production. Fancy children’s furniture, comfortable computer desk tops, carved curved decorations in the doors of kitchen fronts. all these things are possible with the help of machine tools.

There are two kinds of panel cutting machines:

  • vertical, representing a strong rigid vibration-resistant welded bed (frame), set vertically with a 50° tilt to the back, with guides at the top and bottom, on which the saw-bar moves. It is a bracket for the saw unit that slides up and down along the beam and rotates through 90°, which enables both vertical and horizontal cuts. The cutting precision is amazing. For sawing laminated chipboard as well as hard, corrugated or porous boards a special scoring unit is used. The saw has a rotation speed of up to 15,000 rpm;
  • horizontal, consisting of a table for the plate, a carriage for moving the saw along the saw unit and the saw unit itself, consisting of one or two cutting units. The cutting units themselves are equipped with a main saw and a scoring saw. The principle is simple: the main saw penetrates deep into the chipboard and the scoring unit finishes the bottom edge (veneer or laminate surface) accurately and precisely. The saw unit can also be tilted up to 45°.

Trimming saw is a “domesticated” and greatly reduced copy of the horizontal machine. It will not cut a wide sheet of chipboard or laminated chipboard, but it can handle small parts quite well.
