BT Er Collet Chuck bt30 tool holder machine tool accessory milling cutter

BT Taper CNC tool holder ER collet chuck,Milling cutter shank is a kind of machine tool accessory used by Bai to hold milling cutter. It is a part of tool holder system in machining or CNC milling machine. The tool used in the CNC milling machine is connected with the spindle through the toolholder, which is clamped by the toolholder to transmit speed and torque. Turning the milling cutter can achieve the purpose of milling workpiece. The handle of NC milling cutter is made of 20CrMnTi titanium alloy, which is wear-resistant and durable. The tool holder has a hardness of 58-60 degrees and an accuracy of 0.002mm to 0.005mm. It is tightly clamped and has high stability. Features: good rigidity, high hardness, carbonitriding treatment, wear resistance and durability. It has high precision, good dynamic balance performance and strong stability.
