S3I

The new WOTAN® S3I is the ideal machine for high-pre­ci­sion and uni­ver­sal inter­nal grind­ing up to 400 mm in diam­e­ter and 450 mm in length. In addi­tion to clamped work­pieces, it is also pos­si­ble to machine com­po­nents which, due to their geom­e­try, must also be guided in a steady rest.

With our new ’small’ inter­nal grind­ing machine, we are focus­ing even more con­sis­tently on pre­ci­sion and opti­mized processes. A solid gran­ite bed ensures unprece­dented pre­ci­sion, while lin­ear motors and hydro­sta­tic guid­ings guar­an­tee min­i­mum tol­er­ances in the long term. Up to 4 grind­ing tools, in-process mea­sure­ment, optional exter­nal grind­ing and other mod­ules reduce cost-inten­sive non-pro­duc­tive times.

You ben­e­fit from max­i­mum pre­ci­sion with shorter cycle times, higher through­puts and more happy customers.

Key Facts

  • Machin­ing of chuck and shaft-shaped parts (steady-rest guided)
  • Inter­nal cylinder/​ cone, inter­nal poly­gons, inter­nal screw threads and more

For some­what larger com­po­nents, our WOTAN® S6I is also suit­able. For even more machin­ing pos­si­bil­i­ties we offer the uni­ver­sal cylin­dri­cal grind­ing machines WOTAN® S3U and WOTAN® S6U.
