4021 x 20Cr13

critical factors for successful deep face grooving operations

clamping depth = 47

- Parallelism to driver grooves < 0

Non-rotating spindle

Integrated pull-down mechanism

chip breaking

One turning toolholder - four possibilities:

5 with h4-tolerance and Ø 6 – Ø 32 with h6-tolerance

Excellent concentricity in the system (chuck + collet + clamping nut)
