What is CNC tool holder?

CNC tool shank is a part of tool clamping system on machining center or CNC milling machine. The tool used by the CNC milling machine is connected to the main shaft through the tool handle, and the tool handle is fixed on the main shaft through the pull pin and the broach device in the main shaft, and the speed and torque are transmitted by the tool handle. If milling cutter, drill and boring cutter are to be used on a CNC machine tool, they need to be connected with a CNC tool handle system. The machine tool can automatically tighten the cutter and exit the cutter. Advanced Cnc Tool Holder is grasped by the manipulator for automatic tool change, and the whole process is automatically completed by the tool magazine of the machine tool

Tool shanks commonly used in CNC machining are mainly divided into: drilling tool shanks, boring tool shanks, milling tool shanks, thread tool shanks and straight shank tool shanks.

The structure of tool shank of CNC machine tools can be divided into two types: integral type and modular type. The working part of the integral tool handle for clamping the tool is integrated with the handle for installing and positioning the tool on the machine tool. The tool handle has poor adaptability to the transformation of machine tools and parts. In order to adapt to the transformation of parts and machine tools, users must reserve tool handles of various specifications, so the utilization rate of tool handles is low. Modular tool system is an advanced tool system, and each tool handle can be assembled by various serialized modules. According to different machining parts and machine tools, different assembly schemes can be adopted to obtain a variety of tool handle series, so as to improve the adaptability and utilization of tool handles.
