Routing and Drilling

The optimal products for your routing and drilling application

High-speed spindles are the key components of a machine tool. Only when operated in an optimal way, the desired machining accuracy, productivity and service life of the whole machine is guaranteed.

Due to the necessary high rotating field frequency and the small rotor volume, the used high-speed motors require the appropriate frequency converter.

Frequency converters by SIEB & MEYER provide the necessary rotating field frequencies and ensure a low motor heating thanks to the special control technology. The motor heating in particular has a significant impact on the machining accuracy and the service life of high-speed spindles, especially when it comes to the service life of bearings.
