Woodworking milling machine is a woodworking machine tool that uses high-speed rotating milling cutters to slot, tenon and process wood into forming surfaces. Woodworking milling machines are divided into three types: vertical single-axis woodworking milling machines, wood moulding milling machines and router milling machines.
Classification of woodworking milling machines:
- According to the feeding method: manual feeding and mechanical feeding;
- According to the number of spindles: single-axis and double-axis milling machines;
- According to the spindle position, it is divided into vertical milling machine and horizontal milling machine, among which vertical milling machine is divided into upper axis milling machine and lower axis milling machine;
- According to the degree of automation, it is divided into: ordinary woodworking milling machine and CNC woodworking milling machine (single axis, multi axis, universal axis).
The use of woodworking milling machine:
It is mainly to process the external contour or plane of the parts; installing different tools can also perform sawing, tenoning, drilling and profiling engraving.
Features of woodworking milling machine:
Installing different milling cutters on the milling machine will achieve different processing methods and process various required parts. It can tenon, cut, plan grooves and thread the workpiece, and can also be used with tenoning machines. Alternately used, when a special mold is used, the contour milling of the outer contour and the inner closed curve contour can be performed on the parts, so it is widely used. Usually, wood products processing plants will use such machines, so the milling machine is a kind of multi-purpose milling machine. functional equipment.
There are many types of milling machines. According to different feeding methods, milling machines can be divided into manual feed and mechanical feed; according to the number of spindles, they can be divided into single-axis milling machines, dual-axis milling machines and multi-axis milling machines; according to different spindle layouts, they can be divided into Upper and lower shaft milling machines, vertical milling machines and horizontal milling machines, etc. With the continuous development of mechanical processing industry and electronic control technology, the production capacity of woodworking and milling machines has also been rapidly enhanced accordingly. In recent years, automatic machine tools such as automatic mold milling machines and CNC routers have appeared one after another, making it more convenient to process complex wood products.
Precautions for the use of woodworking milling machines:
- When using the milling machine, you should concentrate on your thoughts, especially when two people work on the same machine, you should cooperate with each other and start feeding. According to the material, you should not extend your hand over the knife edge, but let go when you are about 20cm away from the knife edge; Don't push too hard, pull slowly.
- The pushing speed should not be too fast, and it should be adapted to the rotation speed of the milling cutter, the size of the processing amount and the hardness of the material. During the milling process, when encountering parts of the workpiece such as reverse grains or knots, the wood should be pressed down and the feeding speed should be slowed down to prevent the workpiece from bouncing back and hurting people.
- The milling cutter is damaged during processing, and it is very dangerous to throw it from the cutter shaft. Therefore, a milling cutter with good rigidity, a sharp edge and balanced symmetry must be selected; the milling cutter should be installed by experienced workers, and the installation clearance should be appropriate. , The fit with the cutter shaft should be firm, and the blade of the assembled milling cutter should be matched with the groove of the square cutter shaft accurately; during the milling process, pay attention to the balance state of the milling cutter at any time to prevent accidents.
- During the milling process, the workpiece cannot be returned at will, otherwise accidents are prone to occur; in case of special circumstances, it must be returned, and it should be prepared before returning.
- When using the prototype to mill the curved workpiece, if the workpiece is large, in order to ensure safety, the retaining ring should preferably be installed above the cutter head.
