Problems solved by technology

[0006] However, although the above-mentioned methods can partially improve the fatigue strength of the tool, they still cannot meet the demand when the demand is particularly high, that is, they cannot provide a sufficiently satisfactory fatigue strength

Embodiment Construction

[0018] See figure 1 , Shows a schematic diagram of the milling tool of the present invention, the milling tool includes a disc-shaped tool holder 1 and a plurality of blades 2, the multiple blades 2 are evenly spaced around the disk-shaped tool holder 1, the blades may preferably be Cemented carbide, cubic boron nitride or other high-hardness materials, the tool holder 1 has multiple insert seats for accommodating the blade 2, and the blade 2 is fixed on the insert seat. The fixing method can be welding, bonding, screw fixing, etc. .

[0019] See also figure 1 , 2 , Shows the specific structural schematic diagram of the milling tool insert 2 of the present invention. The insert 2 has a rake angle a and a rear angle b. The rake angle is 6-10 degrees, preferably 7-8 degrees, and the rear angle is 17-20 degrees. , Preferably 18-19 degrees. On the one hand, this rake angle provides a certain inclination, thereby providing rapid chip discharge, enhancing cutting rigidity and heat resi...

Abstract

The invention discloses a milling cutter which comprises a disc-shaped cutter rest (1) and a plurality of blades (2), wherein the blades (2) are uniformly positioned around the disc-shaped cutter rest (1) at intervals, and are made of hard alloy or cubic boron nitride; a plurality of blade bearings for accommodating the blades (2) are arranged on the cutter rest (1), the blades (2) are fixed on the blade bearings and are provided with front angles (a) of 6-10 DEG and rear angles (b) of 17-20 DEG; and the cutter rest (1) is excessively hardened so that the hardness of the section of the cutter rest reaches 50HRC (Rockwell hardness). The milling cutter has high fatigue strength under a high load, can effective avoid cracks, and has the advantages of being simple in structure and reducing cost.

Description

Technical field [0001] The invention relates to the field of cutting tools, in particular to a milling tool for milling. Background technique [0002] Milling is more and more widely used in the cutting of metal materials. Milling usually uses multiple blades to cut the workpiece while rotating. While milling, water and other liquids are continuously sprayed to cool and dust the milling position. The continuous development of workpiece materials has put forward higher requirements for milling tools. [0003] The continuous improvement of workpiece materials has made the static and dynamic loads borne by the milling tools become higher and higher. Therefore, the load that the milling tools can bear must be effectively increased. On the one hand, the material of the blade and the bearing load of the cutting edge need to be improved. On the one hand, it is also necessary to improve the geometric design of the insert, and continuously improve the wear resistance and life of milling to...
