24-hour load spectrum on BW test stand with programmable counter-loads.
Highest surface qualities demand the best possible concentricity and total absence of vibration. Consequently, BW only installs gearless spindle units in the MCµ, whose drive system operates decoupled from all vibration.
With 610 Nm, 32 kW (S1) and speeds up to 6,000 rpm, cost-effective precision machining of all materials is guaranteed.
The slim but nevertheless expansive spindle design allows loading of the spindle in house with short tools optimised for concentricity.
The complete spindle cooling system with linear expansion compensation ensures stable length ratios in the process.
