A
method in which heavy stock removal, comparable or superior to milling,
broaching, or turning, is achieved with a grinding wheel. Conventional
and superabrasive wheels are used, dressed by means of diamond rolls,
crush rolls, or by CNC contouring with a diamond disc. Contrary to
conventional grinding, the entire stock is removed in a single pass,
or few passes. |

Creep
Feed Grinding relies on the natural breakdown of the wheel in the
cut to expose sharp abrasive particles. For those applications, which
require optimum sharpness and/or profile accuracy at all times, Dr.
Stuart Salmon developed the continuous dress method whereby the wheel
is continuously dressed during the grinding cycle. |

High Efficiency Deep Grinding, or Abrasive Machining as it is also
called, is very similar to creep feed but utilizes much higher wheel
speeds. Plated super-abrasive wheels are preferred for this process
with speeds generally in the 20,000 to 30,000 SFPM (Surface Feet Per
Minute) range. |
