Lathe Chuck "BR Series" High Precision Large Through Hole Diameter Hollow Chuck
Achieving a high gripping accuracy of 0.01mm T.I.R. or less, overturning the common sense of standard chucks!
A standard chuck that achieves a high gripping accuracy of 0.01mm T.I.R. or less. The lift of the jaws is minimal, allowing for secure workpiece fixation, contributing to improved machining accuracy. It is also compatible with finishing processes. By using the optional special T-nut, T-nut-Plus, a repeatability accuracy of 0.01mm T.I.R. or less is achieved even after jaw replacement! Due to the high repeatability of the jaws, an integrated claw that can handle high-speed rotation can be used, significantly improving setup changes and machining efficiency. Note: In the case of BR12, it will be 0.015mm T.I.R.
