Milling plywood is one of the most common operations in the manufacture of furniture for home and office. The material is more durable than chipboard, chipboard and has a relatively low cost. When cutting blanks on CNC machines, a laser or a milling cutter is used. An automated process facilitates the processing of wood and improves productivity.
Why choose sheet material?
A unique pattern is laid in the memory of the machine, which is instantly transferred to the surface of the workpieces. Machining is defined as CNC plywood milling. St. Petersburg is not the only city where manufacturers mastered multi-axis machines. Technological innovations have made furniture companies competitive.
Laminated material has been around for decades, with consumers leaning towards choosing plywood furniture. High demand for products from consumers was noted. They order their own drawings on the visible surfaces of cabinets, sofas. Advertising signs are also made of sheet material. They have durability, aesthetic appearance after painting and do not require significant customer costs.
Milling plywood is a process of repetitive actions of a working tool that does not leave any burrs on the edges. An automatic work shop allows you to instantly change the tool, ensuring the continuity of the cutting process.
Is the rotational movement of the cutter better?
Furniture workshop owners need laser cutting and plywood milling. Patterns for each type of processing differ in their features. Processing technology takes place in various modes: temperature, speed. It all depends on the desired result.
We highlight the features of machines:
- Laser cutting takes place at high beam temperatures. It leaves dark scorched streaks and spots on the surface. The picture is obtained in the form of a print, does not require additional processing of the edges.
- Milling plywood does not heat the cut. The cutter gradually selects the grooves and makes the surface smooth, light.
Between the layers of the workpiece is an adhesive material. This imposes restrictions on the choice of drill. If the tool does not have sufficient strength, it will instantly become dull.
Processing Issues
Milling of sheet materials often takes place with an axial size of the workpiece of no more than 10 cm. After exceeding the size, special-purpose machines are required, an expensive tool is selected with harder alloys. However, such processing is not possible with laser processing. The seams will turn out uneven and charred.
The beam effectively burns through a thickness of about 1 cm. On this, the laser exhausts its ability to obtain a high-quality part. The milling cutter gets to the most inaccessible places of the product with a three-axis machine design. The additional axis of the clamping table allows you to solve the most complex production problems. When using 5D processing, exact copies of art masterpieces are produced.
However, milling does not allow to obtain such accuracy as on a laser machine. The edge with increasing noticeably differs from the rectangular. The tool exit rounds off the cut, which also creates pressure on the workpiece. The beam does not press on the plywood sheet at all and precisely cuts the given layers. This creates very fragile layouts and shapes.
Features of the cutting process
Milling plywood loads the workpiece, you will need to fasten it with clamps to the base of the table. The rotation of the tool tries to move the sheet along the axis, and the vertical pressure presses the part against the table. But when the cutter leaves the holes, a slight rise in wood is observed. This leads to burrs and chips.
The final product is obtained by repeated processing of the material with various tools:
- End - the manufacture of grooves and internal sections.
- Cylindrical - cutting flat blanks.
- Shaped - make bending grooves.
Description of cut
CNC plywood is milled with a single-input, two-input or four-input tool. However, with an expensive cutter, two types of processing are still required: roughing, finishing. A widely used interpolator is a coordinate transformer for processing cylindrical workpieces.
Metalworking companies offer to manufacture any part according to customer's designs. It is enough to send a file of the established format by mail and in a few days you can already pick up the finished product. This is interesting to customers of advertising organizations. Banners, layouts are obtained original drawings.
Attractiveness is created due to the volume obtained by processing plywood by engraving. Automated operation of the machine provides details with clear contours with smooth bends. To achieve the same quality manually is almost impossible.
