Application:
1, Apply to quickly remove the heat treatment of bearing rings, rolling surface of the oxide skin;
2, suitable for stamping, combined iron holder for chamfering and
deburring, polishing for copper holder to completely replace the
original pickling, polishing process for chamfering, deburring,
polishing not only improve the quality of products, and improve the
working environment, in accordance with the national environmental
protection requirements.
3, apply to bearings, cylindrical roller, tapered roller, spherical
roller, needle roller surface polishing, greatly improve the
surface roughness and brightness
Use of white fused alumina powder:
The abrasive tools made for high carbon steel, Taiwan steel,
high-speed steel and hardened steel and other hard grinding
material, tensile strength is larger. It is suitable for fixing
structure and coated abrasives, wet or dry spray sand, crystal,
ultra precision grinding and polishing of the electronics industry
and the production of high-level refractory materials.
Can also be used as grinding and polishing materials, precision
casting molding sand, spraying materials, chemical catalyst
carrier, special ceramics, advanced refractory materials, etc., it
is characterized by strong cutting force, good chemical stability,
good insulation
