How many racks can I clamp in the Steering Rack Milling Machine S250M?

Both our standard and twin-A1 axes can clamp 2 racks simultaneously for maximum productivity.

Can the Steering Rack Milling Machine S250M mill the toothing on ballscrew racks?

Yes! As well as standard single pinion, the Steering Rack Milling Machine S250M can also mill ballscrew and dual pinion racks.

Can the Steering Rack Milling Machine S250M mill both toothings on a dual pinion rack?

Yes. With the use of our twin-A1 axis that is possible. For mass production we have also  developed a 2-station, stand-alone cell which mills dual-pinion racks with fully automated handling.

What coolant medium is used with the Steering Rack Milling Machine S250M?

We use oil as standard in the Steering Rack Milling Machine S250M. This provides optimal surface finish and lubrication which supports longer tool life.

What experience do Kesel have in the automtive industry?

We have been working alongside Tier 1 automotive suppliers for many decades. This has given us an intimate understanding of the industry's requirmeents. We have machines worldwide at almost every leading manufacturer.

Is milling an effective process?

Milling steering racks offers the very best combination of productivity, precision, flexibility and investment. Continual market feedback has confirmed this year after year.
