How to change the abrasives of a grinder surface to roughness?

[vanquang]

Hello everyone,
Im drawing a grinder wheel.
But I don't know how to the abrasives of a grinder surface to roughness to display in drawing.
May any one help me, please.

There is no relation- you can't specify the 'grit' of an abrasive by specifying a surface roughness.

You should not bother "drawing" the chucks of grinding wheel abrasives.
Make sure the OD, axle (bushing ?), hub configuration, abrasive ID and abrasive wheel thickness are correct. Use a cyl.
