How to choose the grinding wheel in stainless steel polishing
Excellent performance polishing material grinding wheel, mainly used in the cutting of stainless steel, non-ferrous metals, ordinary steel, refractory materials. Excellent materials and exquisite craftsmanship ensure high cutting efficiency and best economic results for different materials.
Polishing material grinding wheel can be compared in the following aspects in stainless steel polishing.

In the first aspect, the size range of the abrasive particles is divided into two categories. 12#-280# is called: sand. W40-W0.5 (or finer) is called micropowder.
In the second aspect, the size range of the abrasive grains: XX# is the size of the sieve, which is the mesh size of the first mesh that the abrasive grains can pass to indicate the particle size of the abrasive grains. WXX is the measurement size, that is, the abrasive grain is small and there is no corresponding screen to measure it, and it is represented by its actual average size.
In the third aspect, the particle size of the abrasive grains is also represented by XXX#--XXXX# when the particle size of the abrasive grains is above 280#. W40-W10 is close to 320#-800#W7-W2.5 close to 1000-3000. Generally, the ordinary grinding wheel can reach W14 (around 600#).
In the fourth aspect, the hardness of the grinding wheel should be selected for different grinding requirements. The coarse grinding should be as good as the ZR level, and the fine grinding should be a harder Z or ZY level.
In the fifth aspect, we need to select the grinding wheel with different polishing materials for different materials. We can choose white corundum for the knife. If you want to grind high green silicon carbide, it is better.
