To chuck and to be concentric is a hard work to do on machining. HYDR-ARBOR can solve your problem of chucking parts of any size and almost any shape, and be concentric within .0001".
HYDR-ARBOR is a reliable tool that uses hydraulic pressure to concentrically expand a steel sleeve, which results in the hydraulic expanding (and / or contracting) arbors and chucks used in any application.
HYDR-ARBOR has been developed as to meet all new standards used in high technology industries. If you talk about precision, ease of use, durability, you can always rely on HYDR-ARBOR chuck and arbor.
