• Working principle of spring collet tool holder

  2020 / 02 / 12

  The spring collet handle is a kind of cylinder-shaped clamp used to imprison the drill or the milling cutter. The collet is installed in the lock nut, and then the lock nut with spring collet is lightly screwed on the tool handle, extension bar or main shaft. It is easy to loosen and fasten by elastic spring steel. It is mainly used to hold light and medium load cutting tools. It is often used to clamp end mills, drills, taps, reamers, center drills and other cutting tools. Change the clamping range by changing different collets. During clamping, the threaded part, locating surface and cone surface of spring collet and lock nut shall be cleaned. During the installation of the collet and the lock nut, the collet and the lock nut must be inclined at a certain angle, and then put into the lock groove of the lock nut. It is not allowed to tighten the spanner too tightly to prevent the tool and clamp from being damaged by falling.

• What is the use of CNC tool holder

  2020 / 01 / 06

  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.

  Shank MT is a type of Morse taper shank, which is divided into bt-mta Morse taper bit shank and bt-mtb Morse taper shank. Bt-mta Mo taper shank is divided into BT30, BT40 and BT50, which share 23 common models. There are 11 types of bt-mtb Mo taper shank, BT30, BT40 and BT50. MT handle precision is 0.005mm, MT Morse taper conversion handle, MTA is flat tail type, MTB is no tail pull type, mainly used for all kinds of tools (such as drill, milling cutter), all kinds of tool rods and machine tool spindle hole taper.
