The Characteristics of Grinding Process
And The Scope of Application
Grinding is high-speed cutting method with multi-blade knife, Its development adapt to the needs of finishing and triangular surface processing . With the level of science and technology, continuous improvement, the precisionand surface roughness of machine parts are becoming higher and higher, a variety of high hardness of the material used more and more, with the development of sophisticated precision casting and forging process, A lot of rough grinding directly into finished products without other cutting ;, In addition, as the development of abrasives and grinding process and continuous improvement of high grinder structural properties , as well as Grinding efficiency and economy of a significant raise, Grinding from the finishing grinding gradually extended to the field of Rough. As a result, modern machinery grinding machine in the use of increasing grinding capacity in the Ministry of machining volume share will increase further.
Grinding the economy can achieve an accuracy of IT6-IT5, in the form roughness Ra value of the 1.25-0.32um. Grinding Technology of the range can be divided into pre-mill (coarse grinding), fine grinding, fine grinding and grinding mirror. Pre-grinding work of the accuracy of IT9-IT8, surface roughness Ra value of up to 0.01um.
As the grinding tools used by the (abrasive) for the stars with small, high hardness, heat resistance characteristics such as good, which can be processed by the general metal cutting tools can not be processed parts with uneven surface such as the hard work CASTING & FORGING On the surface, hardening the surface; processing at the same time to participate in the process of cutting the number of sports stars more than expected, to remove the extremely thin hairline chip, as a result of high-precision surface processing and surface roughness of small value. Pieces of grinding fine plus a way to both single-and small-batch production, than in production, or a large number of mass production have been widely used to rely on in recent years, due to the strong development of grinding, but also directly on a bad hair Used for grinding rough finishing.
