The application area for this HYDRA Expansion Chuck is on a universal grinding machine. The HYDRA Expansion Chuck is flanged directly onto the machine spindle and is operated by the oil pressure of the machine. The special feature of clamping this component is that the two clamping levels are interrupted by grooves or flats. By using a specially slotted intermediate sleeve, the component can be clamped and high concentricity and repeat accuracy can be achieved.
