Grinding pressure

Considering that electroplated grinding tools have a very high concentration, the grinding forces generated are relatively high. For this reason the contact surfaces should, wherever possible, be as small as possible (i.e. narrower rather than wider grinding rims). Stable and rigid machines also have a highly positive effect on the grinding process.

True run / axial true run

As mentioned above, electroplated tools cannot be dressed. This is why radial run-out or axial run-out can only be liminated by straightening. The radial or axial eccentricity must therefore be smaller than 0.02 mm.

Grinding speeds

The optimum grinding speed depends on a number of factors:

- abrasive (Diamond, CBN)
- grinding mode (circular, plane, pendulum, deep cut, and others)
- cooling (oil, emulsion, dry grinding)
- machine ratings (stability, spindle rpm)
- and others

Reference values

Diamond: wet grinding = 15–20 m/s  dry grinding = 10–18 m/s
CBN:        wet grinding = 30–60 m/s  dry grinding = 15–20 m/s


Under optimum conditions, much higher speeds can be used with CBN (e.g. high-speed grinding with 125 m/s).


  • machine designed for high speeds (safety margins)
  • oil cooling with adapted nozzles and sufficient pressure (see illustration)
  • stable conditions (e.g. workpiece holding)
