This is my second belt grinder Viel S-5-M(1/3HP)
It's 4mm thick Robax ceramic glass.
I applied Jende 4 micron & 0.5 micron PDP emulsion to linen belts, but it couldn't remove the burr.(Left is 0.5 micron, Right is 4 micron)
So I tried to 4 micron PDP to Surgi-sharp leather belt, but the result was not different.(Right belt)
Left belt is Surgi-sharp applied with Tormek PA-70. It killed the burr and honed the edge very well. I can get 50~70 BESS with my kitchen knife. But I think 2700 SFM is too fast for using it.
