What is the use of CNC tool holder


Cnc Tool Holder refers to a part of tool clamping system in machining center or CNC milling machine. The cutter used in the CNC milling machine is connected with the main shaft by the tool handle, which is fixed on the main shaft by the broach device in the main shaft and is clamped by the tool handle to transfer the speed and torque. If the milling cutter or drill bit and boring cutter are to be used on the CNC machine tool, they need to be connected with the CNC tool handle system. Through the machine tool, they can automatically tension the cutter and exit the cutter. The advanced CNC tool handle is grasped by the manipulator for automatic tool change, and the whole process is automatically completed by the tool magazine of the machine tool.

The commonly used tool handles in CNC machining are mainly divided into: drilling tool handle, boring tool handle, milling tool handle, thread tool handle and straight tool handle.

There are two kinds of structural forms of tool shank in CNC machine tools: integral type and modular type. The working part of the clamping tool of the integrated tool handle is integrated with the handle for installation and positioning on the machine tool. This kind of tool handle has poor adaptability to the transformation between machine tool and parts. In order to adapt to the transformation of parts and machine tools, users must reserve various specifications of tool holders, so the utilization rate of tool holders is low. Modular tool system is a kind of advanced tool system, each handle of which can be assembled by a series of modules. According to different machining parts and machine tools, different assembly schemes can be adopted to obtain a variety of tool shank series, so as to improve the adaptability and utilization of tool shank.
