In recent years, with high-precision, high cutting resistance and high surface quality of OA equipment, HDD and automotive parts cutting stainless steel is essential. The bar steel surface with a centerless grinding machine grinding, removing harmful surface defects and decarburization, and in terms of poor surface finish, roundness and size of precision can be obtained surface quality, the grinding product with pull Compared to pull products for use in high-precision components.
Table 1 cutting stainless steel and uses
Classification characteristic typical use cases steel
Most excellent corrosion resistance, austenitic, non-magnetic variety of low SF30Z, SF30VFDD shaft, OA equipment
SUS303CU guide rod, the optical fiber connector
Machinability ferritic best SF20T, DHS1 HDD motor housing, sleeve, ball bearings
Corrosion resistance Medium SUS430F
After hardening martensitic get VT13, SF13HDD shaft, small motor shaft
