agricultural bearings Bearing grinding

Bearing grinding: grinding stainless steel material selection method and technical points

Because of some manufacturers of special requirements, Luoyang Boying agricultural ‍bearing production cross roller bearings slewing ring bearings‍ and YRT turntable bearing needs to use the stainless steel material, the need to do not with ordinary high carbon chromium bearing steel grinding, the grinding requirements of stainless steel material are introduced.

1..... Abrasive: white corundum with cutting performance and word sharp good, suitable for grinding martensite and martensitic and ferritic stainless steel; single crystal corundum abrasives suitable for austenitic and austenitic and ferritic stainless steel; microcrystalline corundum abrasive is composed of many small crystals, high strength, toughness and self sharpening good,

The self sharpening Crossed Roller Slewing Bearing‍ characteristics is the gap along the microcrystalline broken column, so as to obtain micro toughness

And micro edge higher, can reduce the burn, hacking and other phenomena, and can reduce the grinding surface roughness, suitable for grinding various stainless steel; cubic boron nitride abrasive high hardness, good thermal stability, high chemical inert, 1300 ℃ ~ 1500 ℃ no oxidation, abrasive blade tip is not easy to blunt, grinding heat is small, suitable for grinding various kinds of stainless steel, in order to reduce the adhesion phenomenon, also can use silicon carbide and diamond abrasive wheel.

2.... size: grinding stainless steel, general grinding wheel with No. 36, No. 46, No. 60 middle size is appropriate, the coarse grinding, the No. 36, No. 46 grain Slewing drives‍ size, with 60 grit grinding. In order to be used for coarse grinding and fine grinding, the No. 46 and No. 60 grain size.

3..... Bond: grinding stainless steel wheel has high strength, in order to bear a larger impact load. Vitrified heat-resistant, resistant to corrosion, wheel it made can keep good cutting performance, moisture resistance, porous, binder for making grinding stainless steel wheel. Grinding tolerance

Concentrated nitric acid stainless steel inner hole, the resin bond grinding wheel manufacturing.‍
