The effect of automatic polishing machine fine buffing

Too much humidity can abate polishing grinding crack effect, make the hard phase in the sample presents projection and non-metallic inclusions in steel and cast iron graphite phase in the "smear" phenomenon; Humidity too hours, because the friction heat production can make the sample temperature, lubrication, grinding surface loses luster, even on the dark spots, light alloy will wound surface.

Coarse behind the purpose is to remove the grinding damage layer, this phase should have maximum rate of polishing, the surface layer of rough cast formation damage is a secondary consideration, choosing also shall be as small as possible; Followed by fine buffing (or end), its purpose is to remove the rough surface damage, make the polishing damage to a minimum. Changshu anhui fine buffing and polishing materials co., LTD. Think rotary speed can be appropriate when progress, polishing time to throw away rough cast damage layer is advisable. The former requires the use of relatively coarse grinding, polishing rate to the larger in order to make sure there are damage layer to remove the grinding, polishing damaged layer is deeper; The latter requires the use of the finest materials, polishing damaged layer is shallow, but the polishing rate, low automatic polishing machine.
