Grinding parameters in tool and cutter grinding
Surface speed Vc
| CBN: |
28 to 35 m/s (5,600 to 7,000 sfpm) for dry grinding ,
28 to 60 (80) m/s (5,600 to 12,000 [16,000]) for wet grinding |
| Diamond: |
10 to 18 m/s (2,000 to 3,600 sfpm) for dry grinding
15 to 25 m/s (3,000 to 5,000) for wet grinding |
Depth of cut ae
The depth of cut depends greatly on the overall stability of the process parameters and the system rigidity of machine tool, tooling and workpiece.
Guideline: approximately 20% of grit size
| B126 (00.125) |
20% = 0.025 mm (0.001 inch) |
| B91 (0 0.09) |
20% = 0.02 mm (0.0008 inch) |
| B76 (0 0.075) |
20% = 0.015 mm (0.0006 inch) |
| CBN: |
0.002 to 0.03 mm (0.0008 inch to 0.001 inch) |
| Diamond: |
0.002 to 0.03 mm (0.0008 inch to 0.001 inch) | |
