Grinding data: 1. Grinding
The device is needed to pre-machine the blank jaws type A. Then, the jaws must be finish ground to the clamping diameter on the D-VARIO chuck. For this operation, the jaws have to be clamped with the grinding rings.
A1 D = 177.0 mm residual jaw stroke 0.25 mm
2. Grinding
A2 D = 176.9 mm residual jaw stroke 0.20 mm
3. Grinding
A3 D = 176.8 mm residual jaw stroke 0.15 mm
4. Grinding
A4 D = 176.7 mm residual jaw stroke 0.10 mm
The clamping diameter A1 is used for the first finish grinding process. The smaller clamping diameter of the grinding rings (A2-A4) are used to regrind worn or damaged existing jaws.
