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.

Facts

  • Avail­able in 4 dif­fer­ent series (S2I, 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

Options

  • Revolver head­stock with up to 4 inter­nal grind­ing man­drels
  • Optional exter­nal machin­ing and fac­ing oper­a­tions
  • Work­piece head­stock with B axis
  • Hydro­sta­tic work­piece man­drel
  • Cen­tre-zero feeler
  • Fixed and/​or pow­ered dress­ing tools
  • Tool change sys­tem
  • Pre-, in- and post-pro­cess­ing mea­sur­ing sys­tems
