What is creep feed grinding?

Creepfeed grinding is a grinding process that can, in most cases, be used as an alternative to reciprocating surface grinding. The main difference is: Reciprocating grinding - the machine table speed is fast (800-1600"/min), and the grinding wheel infeed amount is very small (0.0002-0.002"/pass). ie removing small amounts of material while the table moves quickly back and forth. Creepfeed grinding-the machine table speed is slow (2-50"/min), and the grinding wheel infeed amount is high (up to .25"/pass). ie removing a large amount of material in one (or a few) slow pass. Creepfeed grinders generally require: high rigidity, full machine enclosure, high horsepower spindle drive, high volume/pressure coolant
