Expandable mandrels and high precision clamps with the possibility of manual, pneumatic or hydraulic operation. With the expandable mandrels the parts can be fixed by the internal diameter of the part and also by the outer diameter. The patented double angle design, in addition to guaranteeing much more precise expansion, has for many years proved more versatile and less problematic than the single angle design (commonly used by the competition).


The main characteristics are as follows:

  • Guaranteed accuracy of 0.013 mm (for standard replacement part, better if required)
  • Automatic release and easy loading
  • Greater fixture force when held along the entire length of the clamp
  • Each mandrel adapts to a wide variety of clamps
  • Each clamp has a standard expansion range of 0.8 mm
