What is the use of CNC tool holder?


Cnc Tool Holder is a part of tool holding system in machining center or CNC milling machine. The cutter used in NC milling machine is connected with the spindle through the tool handle. The tool handle is fixed on the spindle through the broach device in the broach nail and the spindle, and the speed and torque are transmitted by the tool handle. Milling cutter or drill bit and boring cutter to be used in CNC machine tools need CNC Tool Holder system connection, through the machine tool can automatically tighten the tool, out of the tool. Advanced by the manipulator to grasp the CNC tool handle for automatic tool change, the whole process is automatically completed by the tool library of machine tools.

The common tool holders in NC machining are mainly divided into drilling TOOL HOLDER, boring tool holder, milling tool holder, threaded tool holder and straight handle tool holder.

The structure of tool holder of NC machine tool can be divided into two types: integral mode and modular mode. The working part of the clamping tool of the integral tool holder is integrated with the handle used for fixing and positioning on the machine tool. This kind of tool holder 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 store various specifications of tool holders, so the utilization rate of tool holders is low. Modular cutting tool system is an advanced cutting tool system. Each tool handle can be assembled by a variety of serialized modules. For different parts and machine tools, different assembly schemes can be adopted to obtain a variety of tool shank series, thus improving the adaptability and utilization of tool shank.
