Problems solved by technology

But, because the center hole of cutting blade is positioned at the center position of blade, and the head of wrench inserts fastening recess and needs larger wrench movable space when fastener is operated, this just has to be set larger on cutter body. Avoid space, the number of edges of milling tools is greatly limited, and the cutting efficiency is low
In addition, with the same efficiency, milling tools with fewer edges have higher cutting force and are prone to vibration

Abstract

The invention discloses a milling cutter, comprising a cutter body, cutting blades and a fastening piece, wherein the cutter body is at least provided with a group of cutter grooves; each cutter groove is internally provided with one cutting blade; each cutting blade is provided with a central hole and fastening piece connecting holes are arranged in the bottom surfaces of the cutter grooves; the head part of the fastening piece is pressed into the central hole and the tail part of the fastening piece passes through the central hole to be connected with the fastening piece connecting holes; the tail end of the fastening piece is provided with a first concave hole which is connected with a wrench in an inserting manner; and the fastening piece connecting holes pass through the cutter body. The milling cutter disclosed by the invention has the advantages of simple structure, convenience for attaching and detaching, relatively-increased blade number, high cutting efficiency, small cutting force and small vibration.

Description

technical field [0001] The present invention relates to cutting tools for metalworking, and more particularly to milling tools. Background technique [0002] In the milling process, the milling tool with the structure that the fastener clamps the cutting blade in the groove through the hole of the cutting blade is simple in structure, easy to assemble and disassemble, and can provide a large clamping force for the cutting blade, so that the milling tool has a relatively Strong impact resistance and long service life, so this tool structure is widely used in milling tools. [0003] Such milling tools are generally used as figure 1 The shown structure rotates around the central axis 5 during its work. It is mainly composed of a cutter body 1, a cutting blade 2 and a fastener 3. The cutter body 1 is provided with at least one set of sipes 11 and fastener mounting holes for cutting The blade 2 is placed in the sipe 11, the fastener 3 passes through the central hole 21 of the c...
