Hydra-Lock Conform-A-Chuck and Conform-A-Arbor workholding solutions are designed to adapt to an out-of-round inside or outside diameter and securely grip to enable boring, honing, grinding, or other machining operations without changing the original shape of the part. Solutions are suitable for machining thin-walled parts such as air pump rotors, gas turbine parts, tubing, and cylinder liners for diesel engines. The company’s Hydra-Fibre plastic material allows the chuck or arbor to expand up to 0.125 in (3.175 mm) and adjust to hold thin-walled and out-of-round components without rounding. By locating on the entire surface, the chuck is able to support the weak component area and withstand tool pressure. Accuracies are typically within +0.001 in (0.0254 mm), and custom sizes are available.
