Description

Technical Field

[0001] The invention relates to the technical field of metal processing equipment, and in particular to a metal workpiece processing device. Background Art

[0002] With the development of modern manufacturing industry, the requirements for metal workpiece processing are getting higher and higher, which is not only reflected in the processing accuracy, but also in production efficiency, cost control and environmental protection. Traditional metal workpiece processing methods usually include turning, milling, drilling, grinding and other mechanical processing methods. Milling is a commonly used equipment in metal workpiece processing technology. Although milling equipment is very mature and widely used, there are still some shortcomings in the actual operation process.

[0003] When a milling machine is used to process metal workpieces, the milling cutter head is very likely to be damaged and broken due to excessive temperature. Since the milling cutter head of an existing milling machine is usually exposed to the outside during operation, the milling cutter head is likely to be blown away when it breaks, causing harm to the operator. In addition, the milling cutter head will generate a lot of metal debris or dust during operation. If it is allowed to fall during operation, it will not only increase the cleaning work after the work is completed, but the debris may also splash and cause harm to the staff.

[0004] Therefore, a metal workpiece processing device is needed to solve the above problems. Summary of the invention

[0005] In order to solve the above problem, that is, to solve the problem that the existing milling machine lacks protection measures for workers when processing metal workpieces, the present invention provides a metal workpiece processing device.
