0.50 carat Diamond on 1/2" x 4" shank
|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.
|Tips - Maintaining your Diamond Dressing Tools
- 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.
