Wheel Loading
(Loading is when material becomes lodged in and on the abrasive grain)

• Incorrect wheel specification (too fine grain)

• Change wheel specification to coarser grit

Wheel Glazing
(Glazing is when exposed grain becomes dull and no new sharp grains are exposed)

• Incorrect wheel
• Faulty operation

• Use coarser grit size
• Soft bond for hard material - hard bond for softer material

Wheel Breakage
       Irregular

• Wheel has been damaged in handling
• Wheel is jamming

WARNING: Stop all operations. Take time to solve the problem. If it persist, call your local representative.

       Chordal

• Too much side load pressure

       Radial

 

• Too much wheel pressure on work surface
• Wheel jams in work surface
• Improper wheel mounting
• Wheel speed too high

Slow Cut Rate

• Not enough power
• Contact area too large
• Grit too fine
• Wheel too hard

• Increase pressure on feed rate
• Reduce contact area
• Use coarser grit
• Use softer, thinner wheel
• Check machine spindle.

Work piece Burn

• Wheel too coarse
• Insufficient feed rate
• Wheel too hard

• Use finer grit
• Try working machine at maximum power
• Go to softer grade wheel

Non-Square Cuts

• Work not properly secured
• Worn spindle bearings
• Wheel too hard

• Check clamps and remove residue from cuts
• Check spindle and alignment
• Use softer wheel

Short Wheel Life

• Wheel too soft

• Use harder bond
