Range of application

The Supfina RaceFlex 725-727 is designed to achieve consistent top quality and highest flexibility in Superfinishing Aeroengine bearings, prototypes or other small production batches. Unmatched versatility is based on the combination of up to four different Superfinishing units in one machine.

The powerful rotary and linear ­oscillator systems for the raceway finishing operation can be complemented with tape finishing units for outer diameters and flanges as well as cup wheel spindles for lip and thrust face operations.

Clamping and centering systems as well as the workpiece drive are just as flexible.

Supfina relies on state-of-the-art modules that have been optimized over decades and that can be adjusted to a new workpiece quickly while requiring only a minimum of type dependent tooling. Due to the intelligent design, set-up times of less than 20 minutes are achieved, supported by NC controlled adjusting axes.
