A kind of multi-blade T-shaped tool and its processing method

Abstract

The invention provides a multi-edged T-shaped cutter and a processing method thereof, wherein the multi-edged T-shaped cutter comprises: a cutter rod, a neck connected with the cutter rod, and a cutting head connected with the neck. The material of the cutter bar, the neck and the cutting head is hard alloy, and the neck and the cutting head are T-shaped. The cutting head is formed with: an even number of evenly distributed cutting edges, and a chip removal groove between the two cutting edges for chip removal; the even number of said cutting edges is in a spiral shape. The cutting edge includes a peripheral edge, and the peripheral edge includes a first flank and a second flank. A chip breaker is provided on the first flank, and the chip breaker is arranged radially along the first flank. The shear angle is 0°. In this way, when the tool is being processed, chips can be discharged in time, and through the chip breaker, the strength of the cutting edge can be improved, and the chip volume can be reduced, thereby reducing the generation of cutting heat and cutting stress, and preventing the product from melting. The problem of chip sticking occurs, which can reduce the phenomenon of knife breakage.

Description

technical field [0001] The invention relates to the technical field of cutters, in particular to a multi-edged T-shaped cutter and a processing method thereof. Background technique [0002] As we all know, plastic materials have poor thermal stability, high coefficient of thermal expansion, and are easy to melt at high temperatures. However, the existing T-shaped cutters for processing plastic materials have a spiral structure for chip removal, and when cutting plastic materials, chips are easily squeezed, resulting in increased cutting heat, melting of plastic products, and chip sticking of the tool. In turn, it is easy for the tool to lose cutting force, resulting in the problem of tool breakage. Moreover, the chip volume of the existing T-shaped tool will be too large, and the cutting stress will be large, which will lead to poor chip removal and the like. [0003] Therefore, the prior art needs to be improved and developed. Contents of the invention [0004] The pur...
