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).
