CBBT collet chuck is BT taper collet chuck’s end face and taper double contact with spindle. The double face contact design is mainly to improve the rigidity, stability and precision of the tool holder.
Based on the mechanics theory, the larger the diameter of the reference point, the stronger the rigidity. The common system is the standard diameter of the taper shank end diameter; the benchmark BBT diameter is the flange diameter, which significantly improves the rigidity.
s Increase the stability of the tool holder during high-speed machining;
s Reduces the phenomenon of poor accuracy caused by tool holders during high-speed cutting;
s Larger contact diameters help increase the number of extensions;
s Improved tool stability can increase tool life, ensure repeatable positioning accuracy after tool change, and improve boring Roundness during hole cutting
