SPF Range Smoothing & Polishing Machines

Dama_SPF

Single or multi station smoothing and polishing machine with single or double eccentric horizonal overarm to process high precision plane or spherical surfaces.

For flat optical components of high precision.

The present design follows a newly developed modular concept:

  • Each spindle, of both smoothing and polishing device, features its own drive.
  • The tool contact forces are individually controlled pneumatically, which permits you to attain smoothed and polished surfaces of top quality.
  • The double eccentric drive forms a unit which copes with all smoothing and polishing work.

Thanks to the individual adjustment at the eccentric it is possible to generate any number of polishing patterns. The result is an optimal quality achieved in the shortest possible time.

  • The machine features a welded, sturdy base frame covered by a solid plastic plate.
  • The smoothing and polishing tubs are recessed in the top plate and removable.
  • The working spindles and eccentrics are driven over toothed belts, a solution which provides enormous advantages in respect of loss of force and servicefriendliness.
  • The speeds are freely selectable.
  • Spindle stability and precision are assured by a suitable cone and ball arrangement.

On request the machine stations can be operated individually.
