By utilizing DONE IN ONE capability from Mazak Integrex machine with a second turning spindle, all processes from raw bar stock material to final machining in just one machine to improve machining accuracy and streamline production output. Innovative coating process significantly increases the clamping force by 75% compared to standard ER collet nut. More gripping force provides better rigidity and reduces the possibility of losing grip on the round shank which lead to expensive damage on cutting tools and work piece material. SHARS Dual Contact tool holder can only be used on machine center with dual contact spindle.
