Clutch-operated screw presses SPKA with continuously revolving flywheel and integral clutch represent a distinctive type of energy-bound press from SMS group. This machine concept enables process options that are not available with other press types. Due to the flexible clutch drive system, the machine type has achieved great success on the market for heat-sensitive materials, e.g. for aircraft and power station components.Our screw presses apply high forming energy even at reduced ram speed. What makes this possible is our special clutch disengagement technology. Also important are the minimum workpiece contact times. Clutch disengagement can be force or stroke-controlled and all functions are controlled electronically.

Customer challenges addressed

  • Strong forming forces with short workpiece contact times: Enables effective forming while reducing thermal load on heat-sensitive materials.
  • High useful forming energy due to special clutch technology: Makes a high amount of available energy usable for the forming process, even under demanding conditions.
  • Full performance even at 50% of the nominal stroke rate: Delivers maximum forging power already at reduced stroke rate, increasing process flexibility.
  • Variable ram speed: Allows the press motion to be adapted to different materials, geometries and process requirements.
  • Hydraulic flywheel bearings: Support smooth flywheel operation and contribute to reliable machine performance.
  • Low accelerated masses: Reduce the mass that must be moved each stroke, improving dynamic response.
  • Short acceleration distance: Reaches maximum ram speed quickly, enabling short stroke times and fast operating sequences.
