What is Creep-Feed
Grinding?
Conventional grinding involves a grinding
wheel reciprocating rapidly over the workpiece as it gradually lowers to it's
final depth of cut. Creep-feed grinding is a process where a formed grinding
wheel is plunged into the workpiece, effectively producing a finished part in a
single pass. Other aspects of creep-feed include:
- Chips are formed along the arc of contact like
a conventional milling operation
- Very high forces are generated during
creep-feed grinding, requiring machines specially designed for rigidity
and power
- The coolant must be carefully controlled to be
effective in the deep arc of contact
- Fast cycle time
- Good Repeatability
- Close tolerances (to tenths in production)
- Improved fatigue resistance from mild residual
compressive stresses
- The ability to machine super alloys and fully
hardened materials
- Burr-free surfaces
- Superior surface finishes
