ADVANTAGES OF CREEP-FEED (FULL-DEPTH) GRINDING
vs CONVENTIONAL MACHINING
- Increased productivity and quality of parts requiring slots and/or profiles.
- Eliminates costly first operations such as milling, broaching or turning. The form or slot can be creep-feed ground to full depth from the solid.
- Fully hardened parts can be creep-feed ground from the solid--thus, in many cases eliminating the need for straightening operations required prior to conventional reciprocation grinding after milling and heat treating.
- Reduced handling time and cost. For example, a conventional machining process of a part may require:
- Milling
- Deburring
- Heat Treat
- Straightening
- Reciprocating Grinding.
Whereas with creep-feed, the milling, deburring, straightening, and extra handling operations can be eliminated.
- Reduced set-up time and costs due to combined operations.
- Reduced tooling costs (i.e., formed milling cutters, broaching tools, etc. as compared to grinding wheels).
- More parts processed per wheel life due to less wheel breakdown when compared to reciprocation grinding.
- Reduced wear on dressing tools due to the use of softer wheels.
- Wheel form maintained longer--thus, requiring less redressing and resulting in increased productivity.
- Reduced grinding wheel cost due to less wear and fewer number of dressing operations required.
- Improved tolerances and surface integrity as opposed to milling, broaching or turning.
