The synchronous motor technology realizes a slim and 87mm long powerful 182W motorspindle. The 25mm cylindrical housing makes it possible to install the motorspindle on cutting and turning centres as well as on automatic lathes, in medical or micron technologies. The motorspindle can also be built in a special housing with variable shaft diametre and a length of 58mm. This brings an advantage in using for backwards operations. For higher productivity you can choose the motorspindles with adjustable angle.
The motorspindles are either used for Grinding, Cutting, Micro-Drilling and Engraving, in tool and mold making or in production of optical and micronical parts. The selectable MEGA-3S collet system allows a runout less then 1µm in the cone and max. 3µm at 4xD.
Optionally there are 90° connectors and housing extensions available.
The optimized IBAG converter guarantees a trouble-free application. The motorspindle can be controlled either manual or by the CNC of the machine.
