Then turn 180 degree, do the same operation until grinding out the relief angle.
e . Turning the adjusting handle( handle 1) of grinder to make the tip of cutters have some gap with the grinding wheel.
f . Loose the relief angle nut and then upper the cutters to grinding the front clearance angle. Then lock the nut again.
g . Turning the Cutter’s adjust handle( handle 1) until the cutter touch the grinding wheel and then grinding the front clearance angle.
8. The Front angle grinding
a . Adjust the crosswise handle and the longitudinal handle until the grinding seat have some distance with the grinding wheel.
