Precision machining technology was proposed in the 1960s. It is an important way to improve the performance, quality, working life and reliability of electromechanical products, as well as the ability to save energy. Optical tool processing is an indispensable process in precision machining!
Generally, a precision machining refers to a processing technology with a machining error of less than 0.1 m and a surface roughness of less than Ra 0.025 Ixm, also known as sub-micron machining. The level of precision machining technology is one of the important signs of a national manufacturing industry.
So what are the factors that affect the quality of the optical diamond tool when it is precision machined?
1, processing mechanism
In the traditional processing methods, ultra-precision cutting of optical diamond tools and ultra-precision grinding of diamond micro-powder wheels occupy an important position. In non-traditional processing, there are various methods such as high energy processing such as electron beam, ion beam, and laser beam, microblog processing, and ultrasonic processing.
2, the material to be processed
Precision-machined parts require a variety of materials to meet a wide range of requirements. For example, the material to be processed is required to have uniform texture, stable performance, no external and internal microscopic defects, and no impurities; its physical and mechanical properties, such as tensile strength, hardness, elongation, modulus of elasticity, thermal conductivity and expansion coefficient, etc. It reaches a certain order of magnitude; in the process of smelting, casting, rolling, heat treatment, etc., the slag filtration, rolling direction, temperature, etc. should be strictly controlled to make the material pure, the grain size is symmetrical, non-directional, and can meet the physics. Chemical, mechanical and other performance requirements.
3, processing tools
Precision machining tools are mainly tools and molds. Ultra-precision cutting with optical diamond tools requires attention to the ultra-precision sharpening of diamond tools, with a population radius of 2-4 nm. At present, the grinding tools mainly use ultra-precision grinding of diamond micro-grinding wheels, which have problems such as abrasive grain size, adhesive, and trimming.
