Micron's Grinding Processes

Creep Feed Grinding
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.
Continuous Dress
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.
HEDG Grinding
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.
