WEMA SI solves simple and complex internal grinding tasks quickly and efficiently. A multi-settable internal round table and a work headstock are guided to the μm. As with all our machines, SI is scalable and is adapted to your needs through a specific mounting for the greatest machining efficiency.
Since time is always important, we rely on our optimised procedures: Our powerful drives ensure a quick availability with additional work and peripheral modules reducing costly non-productive times. You stand to benefit from this through reduced cycle times, greater throughput and more satisfied customers.
Key Facts
- Available in 3 different series (S3I, S6I, S10I)
- Machining of chuck and shaft-shaped parts (steady-rest guided)
- Internal cylinder/ cone, internal polygons, internal screw threads and more
- Up to 4 applicable internal grinding tools (fixed on B2 axis)
- High rigidity through the use of cast beds / Hydropol beds
- External machining of the components possible
