Keeping Your Grinding Operation Cool with Machine Lubricant. Grinding fluid is equally important. So-called neat oil is the most lubricious, reducing friction and therefore heat, but it does a poor job of removing whatever heat does remain. This can negatively impact part accuracy. Water-soluble fluid does an excellent job at cooling the ...

But it is a mistake to increase grinding speed in order to improve production rate. While this may seem to make some sense, typically you end up with the opposite result. And this is why: higher grinder speed equals higher diamond temperature. At high temperatures, your diamond tooling will "glaze over" and literally seal the diamonds under a ...

Cutting Fluids. Whenever possible, use grinding fluids with your diamond wheels. They reduce the grinding heat while extending the life of the wheel. Applying coolant the right way is also important. When applying the coolant, allow the centrifugal force of the wheel to distribute it in a constant stream to the area of grinding contact.

To maximize productivity and performance when cutting, use a rocking motion with the grinder. This motion reduces the heat being produced from the abrasive contacting the metal, which speeds up the cut and increases wheel life. Less heat in the cut also helps minimize the time spent on rework. The extent of the rocking motion depends on the ...
