Technical Field

The invention relates to a 4-edge milling cutter and a manufacturing method thereof, and belongs to the technical field of woodworking tools.

Background

Disclosure of Invention

In order to overcome the defects of the prior art, the invention provides a 4-edge milling cutter and a manufacturing method thereof.

A4-edge milling cutter is formed by grinding and processing a whole hard alloy, and has 4 cutting edges, wherein two symmetrical cutting edges are finish milling cutting edges, and the other two cutting edges are provided with mutually staggered chip breakers.

The size of the arc radius R of the chip breaker is R0.8-R1.5mm.

A manufacturing method of a 4-edge milling cutter comprises the following steps; the 4-edge milling cutter is arranged on a fixture, the 4-edge milling cutter can rotate on the fixture, chip breakers are machined by using a grinding wheel or diamond grinding wheel grinding machining method, the 4-edge milling cutter is rotated, the grinding wheel or diamond grinding wheel is moved to the position where the chip breakers are required to be machined, and the chip breakers are machined sequentially.

The invention has the advantages that: the chip breaker is machined by using the wire cut electrical discharge machining method, so that the relief angle of the chip breaker can be machined, the chip breaker effect can be machined and enhanced, the machining precision is high, the chip removal effect and the heat dissipation effect are effectively optimized on the basis that the machining effect is guaranteed by 4 cutting edges, and the service life of the milling cutter is finally prolonged.
