Differences Between Thru-Feed And In-Feed Grinding

In-feed grinding is also a form of centerless grinding. This process, however, is optimized for workpieces with complex or abnormal shapes. The workpieces must be manually loaded into the grinding machine and then the regulator wheel is manually moved, as well. This process is optimal for complicated parts and wheel shapes.

Grinding Process, Finish Machining, Aerospace Parts ...

In creep feed grinding, the machine table feeds the work piece in the direction of the grinding wheel rotation. While the table speed is slow—“creep feed”—the depth of cut is very high, which results in a high material removal rate. The creep feed grinding process offered significant productivity enhancements over conventional grinding.
