10. GRINDING TIPS

1.
Ensure that the item to be ground is comfortably and securely held.
2.
Adjust tool rest to correct angle.
3.
Present the workpiece smoothly on to the grinding wheel face with a light and even
pressure.
4.
Grind against the edge of the workpiece to avoid burrs.
5.
Never grind on the sides of the wheels.
6.
Best results are achieved if the grinder is allowed to rotate at its maximum speed. Excess
pressure from the workpiece can damage the wheel and overload the motor.
7.
Check grinding wheels regularly for wear or damage. Replace wheels that are worn
more than 25%. Damaged wheels should be discarded immediately as they are
dangerous and can cause the grinder to vibrate.
8.
After grinding fine edge tools, they should be honed by hand on a fine slip stone.
