T-shaped milling cutter

Abstract

The invention discloses a T-shaped milling cutter. The T-shaped milling cutter comprises a T-shaped milling cutter body, chip removing grooves, a cutter belt and cutter teeth, wherein the T-shaped milling cutter body takes the shape of a circular shaft; the chip removing grooves are spirally formed at the outer periphery of the T-shaped milling cutter body in the peripheral direction of the axis from the front end of the axial direction of the T-shaped milling cutter body to the tail end side; the cutter belt is formed on an arc surface between two adjacent chip removing grooves towards the outer peripheral surface of the T-shaped milling cutter body; the cutter teeth are projected on the outer wall of the cutter belt, and are arranged in the peripheral direction of the T-shaped milling cutter body; and two adjacent cutter teeth are staggered at the periphery. The cutter teeth are staggered at the periphery, and the cutting width of workpieces is the width sum of two adjacent cutter teeth, so that the cutting width of each cutter tooth is smaller than the cutting width of the workpieces, and the cutting resistance of single cutter tooth is reduced; and meanwhile, the cutting widthof the workpieces is not changed, so that the cutting quantity of single cutter tooth can be increased, the machining efficiency of the workpieces is improved, and the service life of the T-shaped milling cutter is prolonged.

Description

technical field [0001] The invention relates to the technical field of cutting tools, in particular to a T-shaped milling cutter. Background technique [0002] A milling cutter is a rotating tool with one or more teeth for milling. When working, each knife tooth cuts off the allowance of the workpiece intermittently in turn. Milling cutters are mainly used for machining planes, steps, grooves, forming surfaces and cutting off workpieces on milling machines. [0003] In the process of realizing the present application, the inventor found that the prior art has at least the following problems: when the existing T-shaped milling cutter mills the workpiece, in order to improve the processing efficiency of the workpiece, the cutter teeth of the T-shaped milling cutter are added. However, this method is prone to the problem of T-shaped milling cutter breaking or damaging the teeth, which shortens the service life of T-shaped milling cutters, increases production costs, and incre...
