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
