Hints in the Use of Grinding Wheels

Hints in the Use of Grinding Wheels.

A wheel used for wet grinding should not be allowed to stand partly immersed in water. The water-soaked portion may throw the wheel dangerously out of balance.

New wheels should be run at a working speed for at least one minute before applying work, during which time the operator should stand at one side.

The work rest should be kept adjusted close to the wheel to prevent the work from being caught. Work rests should be rigid and always securely clamped after each adjustment. The rests should not be adjusted while the wheel is in motion.
