Abrasive Wheel Grading

Wheel acts too hard indicated by:
• Loss of cutting action.
• Wheel loading.
• Work discoloured, burned
• Work chattering.
• Increase work speed (regulating wheel) and pressure.
• Dress with sharp diamond at increased traverse rate.
• Use thinner coolant; avoid gummy coolants. Increase work speed; use softer wheel.
• Use coarser grain size and softer grade.
Wheel acts too soft indicated by:
• Short wheel life.
• Wheel markings on work.
• Not holding cut.
• Decrease work speed (regulating wheel). Wheel too soft.
• Slow down traverse and work speeds, also work pressure.
• Dress wheel with slow traverse and light penetration. Take lighter cuts when grinding. Wheel too soft.
