Speed Version
Achieves even shorter non-productive times due to increased acceleration
and rapid traverse rate as well as short tool change time and torque table.
- 10 m/s² acceleration
- 90 m/min rapid traverse in X, Y and Z axes
- approx. 3 seconds chip-to-chip time
The new "Speed Package" for the NBH 5+ does not only extend the already numerous options available but also the operating range of these horizontal machines especially for Al, HSC and light metal machining, a segment which is getting more and more dominant in the automotive industry and with suppliers to the automotive industry.
With the 35 kW, 15,000 rpm and high dynamic motor spindle the NBH 5+ meets the requirements for economical production.
Spindle cooling, HSK 63 tool taper and tool taper cleaning are standard - in addition to the proven original Hüller Hille tool magazine cassette system and the traditional high quality standards.
Torque table
- Very good dynamic features
- High torque
- High rapid traverse B axis 80 rpm
- Excellent accuracy as feed axis
