Präwema spindle and motor spindle repair
Brochexpress is an independent workshop specialising in the repair, maintenance and diagnostics of Präwema spindles and motor spindles — the German manufacturer from Eschwege, specialising in gear finishing machines using power skiving and synchronous broaching.
Präwema, the German specialist in gear skiving and synchronous broaching
TLDR: Präwema Antriebstechnik GmbH (Eschwege, Germany) is a builder specialising in gear grinding, honing and gear machines, with particular expertise in power skiving, a tooth machining method that synchronises the rotation of workpiece and tool.
Präwema Antriebstechnik GmbH, based in Eschwege, Germany, designs gear grinding machines, gear honing machines and gear machines, distributed worldwide through a network of agents. The manufacturer has made its name in particular in power skiving, a technology patented as early as 1910 by Wilhelm von Pittler but which only found broad industrial application recently, thanks to advances in universal machining and turning centres fitted with synchronised spindles. Power skiving allows machining up to three times faster than gear shaping.
A range of synchronised spindles for skiving and synchronous broaching
TLDR: Präwema machines use spindles perfectly synchronised between workpiece and skiving tool, rigidity and synchronisation accuracy being the essential conditions for process quality, with a Y axis mandatory for this application.
Power skiving requires a perfectly synchronised machine and tool to deliver the highest quality, with spindles rigid enough to withstand cutting forces at high speed while maintaining rotational synchronisation between workpiece and tool. A machine fitted with a Y axis is mandatory for this application, together with a suitable toolholder and a dedicated skiving tool. This high-precision synchronisation between spindles also allows synchronous gear broaching, an alternative to conventional broaching.
Präwema spindles covered (non-exhaustive list)
- Synchronised spindles for power skiving (workpiece and tool)
- Spindles of gear grinding and honing machines
- Spindles working with the Y axis required for skiving
