The WOTAN® S3I in its con­fig­u­ra­tion as WOTAN® S3I-F is suit­able for high-pre­ci­sion cylin­dri­cal grind­ing to process inter­nal diam­e­ters of chuck parts with a swing diam­e­ter of up to 400mm and a work­piece length of 400mm that are clamped on one side only (“fly­ing”) with­out addi­tional sup­port – espe­cially suit­able for grind­ing inter­nal front sur­faces as well as inter­nal diameters.

As an alter­na­tive, the machine can be con­fig­ured with an extended work area as WOTAN® S3I-L. This ver­sion makes it pos­si­ble to process shaft-type com­po­nents with a legth of up to 750mm and a diam­e­ter of up to 250mm, apart from chuck parts clamped on one side only, for which, due to their geom­e­try, a steady rest needs to be added.

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

  • 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
  • WOP-TouchTM user interface

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.
