Problems solved by technology

This method is difficult to fix the chuck part of the milling cutter. Due to the high-speed rotation of the spindle, the damping particles in the tool holder may also be eccentric, which will make the coated tool vibrate more violently and the coating will fall off.

Abstract

The invention relates to a cutter handle with a shock absorption function. The cutter handle with the shock absorption function comprises a handle body, a damping block and a clamping head, wherein aninner hole is formed in the handle body and used for holding the damping block and the clamping head. The damping block is arranged at the bottom of the inner hole. The clamping head is arranged on the upper portion of the damping block. Four to six circles of grooves are formed in the surface of the inner hole. Shock absorption devices are arranged in the grooves and surround the periphery of the clamping head. The cutter handle with the shock absorption function is simple in structure, and convenient to use. When stone is machined, shaking or vibration of the surface of the stone is reduced. The damping block and the shock absorption devices convert kinetic energy into potential energy, the vibration amplitude of the milling cutter clamping head is relieved, vibration of a milling cutter is further relieved, and the surface coating of the milling cutter is protected. The machining accuracy of the surface of the stone is improved, and the service life of the coated cutter can also beprolonged.

Description

Technical field: [0001] The invention belongs to the technical field of coated cutting tools, and in particular relates to a cutting tool holder with vibration damping function. Background technique: [0002] The vibration of the machine tool in the process of milling stone is very complicated. There are many reasons for the vibration, mainly: because the internal structure of the stone is not uniform and is a hard and brittle material, a large enough external force may be generated during milling. Moreover, the frequency of the external excitation force is the same as the natural frequency of the process system and then resonates; the shape of the stone is complex and diverse, and the selection of the clamping position when processing the stone is unreasonable; the selection of parameters such as cutting amount and machine speed is unreasonable; it may also be some forced Vibration, such as the foundation of the machine tool, the gap of the screw of the machine tool, the da...
