With WEMA SU a uni­ver­sal grind­ing machine is now avail­able for the more com­plex task of the four-way machin­ing of all major work­piece sizes. The machine is equipped with vari­ably fit­ting exter­nal and inter­nal grind­ing units. The result­ing machin­ing work with just one clamp­ing oper­a­tion pro­vides deci­sive effi­ciency and pre­ci­sion benefits.

Ver­sa­til­ity is the key to con­fer­ring a major edge. Our tech­nol­ogy enables machines to per­form highly com­plex oper­a­tions. At the same time, our effi­cient periph­eral mod­ules allow a flex­i­ble reac­tion to your indi­vid­ual pro­duc­tion require­ments. This allows you to reduce labour costs and pro­duc­tion times.

Key Facts

  • 4 sides can be machined in one clamp­ing operation
  • Up to 3 swivel axes
  • Machin­ing of chuck and shaft-shaped parts (steady rest guided)
  • Up to 4 insertable inter­nal grind­ing tools (fixed on B2 axis) and 4 exter­nal grind­ing tools (fixed on B3 axis)
  • Exter­nal grind­ing wheels with a max­i­mum of 600mm diameter
  • var­i­ous options pos­si­ble (acoustics emis­sion (AE), dress­ing spin­dles, CBN, etc.)
