Roller revolutions 40-60 rpm

Feed (Traversing speed) 0,25 - 0,49 times width of grinding stone per roller revolution

Periphery speed of grinding stone 33-35 m/s

·      First rough grinding. 0,1mm. in-depth and two passes.

·      Clean the stone with a rubber cleaning rod.

·      Second grinding. 0,05mm. in depth. One pass. Use a chalk block after the grinding wheel.

·      With no changing in depth, grind three times using the chalk block.

·      Clean the roller surface with a smooth brush, and then alcohol.
