WEMA SI solves sim­ple and com­plex inter­nal grind­ing tasks quickly and effi­ciently. A repeat­edly allo­ca­ble tool and a work­piece head­stock are guided on up to six axes with an accu­racy of 0.1 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. We can also arrange financ­ing accord­ing to your frame­work conditions.

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
  • includ­ing intu­itive WOP-TouchTM user interface

Our WOTAN® S3I is also suit­able for smaller and lighter com­po­nents. For even more machin­ing pos­si­bil­i­ties we offer the uni­ver­sal cylin­dri­cal grind­ing machine WOTAN® S6U.

WOTAN® S6I‑F

Inter­nal cylin­dri­cal grind­ing ­machine for pro­cess­ing very heavy com­po­nents or par­tic­u­larly deep inter­nal diam­e­ters with the high­est pos­si­ble degree of precision.

WOTAN® S6I‑L

Inter­nal cylin­dri­cal grind­ing machines of the WOTAN® S6I series are designed for pro­cess­ing medium-sized and large work­pieces. The work­piece spin­dle can absorb loads of up to 1 200 kg.
