GENERAL RULES WHICH APPLY TO SUPERABRASIVES ARE:

¨ Do not use Diamond on ferrous materials.

¨ Do not use CBN on steel under Rc 50.

¨ Machines must be in good working order with good bearings and rigidity.

1. Storing and Handling

Wheels should be stored separately and protected against shock and contact to reduce the risk of damage. Wheels may be left mounted on spindles and flanges but should be wrapped before storage. Otherwise keep wheels in their boxes when not in use.

2. Coolant

It is always advisable to use superabrasives with coolant as performance is superior (sometimes by a factor of 10 times). Many coolants are available but water with an addition of rust preventor or soluble oil (1.5 to 2%) is often adequate. Whilst giving longer life to wheels the use of coolant also minimises the thermal damage to the workpiece and wheel. This guarantees workpiece integrity and dimensional accuracy by reducing heat distortion to a minimum. The use of coolant will also help in obtaining a better surface finish. It is generally accepted that straight oils generate a better finish than emulsion or simple aqueous solutions,and markedly better than the absence of any fluid. Coolant also acts as a lubricant and lowers spindle power drain, it reduces the force needed to remove stock thereby lowering heat generation and increasing wheel life. The final function of coolant is to remove swarf from the abrasive rim. This prevents wheel loading and helps to maintain freeness of cut. To get the best from your coolant flood the workpiece/wheel contact area. Have a large tank to allow swarf to settle out and if possible filter out impurities and fine swarf. A small trickle of coolant occasionally applied is worse than no coolant at all. This causes alternate heating and quenching, which can cause damage to the wheel and workpiece. A good way to apply coolant

is to allow the centrifugal force of the wheel to deliver it in a steady stream to the point of grinding contact.
