High repeatability, long working life, compact design.
Machine structure
The following specific technological particular parameters characterize the NBH 95 up to NBH 155 which closes the gap in this price range:
- High accuracy through jig boring mill axis arrangement (i.e. Z axis in workpiece)
- High torque through geared headstock
- Covering of guideways in all axes
- Economical machining of steel and cast components and suited for compacted graphite cast iron
- Spindle speed 10,000 rpm (NBH 95/NBH 135) suited for mixed machining with aluminum materials
- Speed package (NBH 95/NBH 135) with HSC motor spindle for 16,000 rpm
- Fast machine design: approx. 4 seconds chip-to-chip time and approx. 7 - 8 seconds pallet changing time
