Tips - Maintaining your Diamond Dressing Tools
Results of Neglect - you may recognise these signs.
Chatter or gouge marks - Diamond broken or chipped.
Diamond lines on work - Increased diamond wear or broken diamond.
Chatter marks on work - Diamond is dull and is crushing rather than dressing the wheel.
Reduced diamond life due to burning - poor flow of coolant on diamond whilst dressing.
Maintain sharp diamonds
A dull diamond tends to crush the grains into the bond of abrasive wheels and crack them without giving a clean break.
Grains of wheels that have been crushed in this manner will give the effect of wheel loading - cracked grains will also come out whilst grinding and produce scratch marks in work.
Some precautions when setting up a diamond tool
Be sure diamond holder is securely held with minimum overhang.
Be sure diamond is not cracked, burned or flatted.
Be sure, whilst dressing, the diamond is not subjected to excessive shocks or bumps.
For best grinding finishes be sure diamond cutting angle is not too sharp.
Be sure, whilst dressing, the contact point of the diamond receives plenty of coolant.
Whilst dressing, diamond cuts should not exceed 0.001" per pass.
