Laser tool grinding method and tool grinding machine

Abstract

The invention discloses a laser tool grinding method and a laser tool grinding machine. High-quality laser replaces a grinding wheel or discharge machining and precisely machines tools, moulds and work pieces with the shape or mode similar to that of tools and moulds. The method comprises the following steps: a work piece is arranged in a fixture of a mounting tool, the position of the work piece to be machined is adjusted to an optimum angle and an optimum position; a point to be machined is arranged at a laser focus or a focal plane, laser and cooling air or cooling fluid are started, a high-precision multidimensional motion system is electrically or manually controlled to lead the machined region to move according to a fixed law, thus forming tool cutting edges of various shapes. Non-contact machining does not cause pressure and stress damage due to wheel grinding and does not cause discharge damage due to electrical discharge grinding, either. The method and the machine have high quality: when the laser quality is higher, cutting edges with smooth and clean mirror surfaces can be machined, and the efficiency and the quality are both superior to those of the electrical discharge grinding. The method and the machine have high efficiency: the efficiency of the laser grinding is far higher than that of the discharge grinding and the wheel grinding. Real-time monitoring is easy.

Description

technical field [0001] The invention relates to a laser tool sharpening method and a tool sharpening machine, which use laser as a processing medium to precisely remove materials from metal or non-metal workpieces so as to obtain required shapes. In particular, the invention relates to precision knives, dies and processes of shape or form similar to knives and dies. The process equipment involved in the present invention belongs to the field of precision cutting equipment. Background technique [0002] Currently commonly used processing methods: [0003] Prior art one: [0004] A processing method that uses grinding machines and equipment similar to grinding machines to use grinding wheels as grinding materials. [0005] Working method: Driven by a motor or other power source, the grinding wheel rotates and contacts the surface of the workpiece to be processed, and the workpiece material is removed by the friction between the abrasive and the workpiece. During the fricti...

AI Technical Summary

Problems solved by technology

[0018] The cost and process difficulty of metal bonded grinding wheel are relatively high, and the economy is not ideal when used for small batch processing of the same kind of workpiece

Therefore, the application field is not very wide, which also restricts the development of such equipment functions. The common ones are some special machine tools with relatively simple motion systems.
