Embodiment
[0013] Such as figure 1 , 2 As shown, the forming chamfering tool of this embodiment is processed by using a CNC five-axis linkage grinding machine and independently programming the tool program. The base material is made of hard alloy, and the surface is provided with a TIALN coating.
[0014] Specifically, the profiled chamfering knife includes a shank 1 and a blade 2, the blade 2 includes a chip flute 4 and a chamfering edge 3 at the end, the key lies in the chip flute of the profiled chamfering knife 4 is a straight flute structure, and the flute 4 extends to the end of the forming chamfering edge 3 . Compared with the traditional spiral groove, the chip flute 4 of this chamfering knife adopts a straight flute structure, and the end of the chip flute 4 extends to the end of the forming chamfering edge 3, which improves the chip removal during processing. As a result, the temperature generated during processing is greatly reduced and the tool life is improved.

The invention aims at providing a molding chamfering tool; the chip removal effect of the molding chamfering tool can be improved, and generated temperature during processing can be lowered, and therefore the service life of the tool is prolonged, and the use cost of a client is reduced. The molding chamfering tool provided by the invention comprises a hilt part and an edge part, wherein the edge part comprises a molding chamfering edge at the end part. The molding chamfering tool is characterized in that a chip groove of the molding chamfering tool is of a straight groove structure, and moreover, the chip groove extends to the end part of the molding chamfering edge. Compared with the traditional spiral groove, the chip groove of the chamfering tool is of the straight groove structure, and moreover, the end part of the chip groove extends to the end part of the molding chamfering tool, and thus, the chip removal effect during processing is improved, so that the generated temperature during processing is greatly lowered, and the service life of the tool is prolonged.
Description
technical field [0001] The invention belongs to the technical field of cutter manufacturing, and in particular relates to a forming chamfering cutter. [0002] Background technique [0003] Forming chamfering knife, as an important part of machining tools, is mainly used for hole forming chamfering. With the development of the machinery industry, users have put forward higher requirements for product processing quality, processing reliability, processing efficiency, and tool delivery time. The chip removal groove of the traditionally designed forming chamfering knife adopts the form of a spiral groove. During high-speed cutting, the chip removal effect of the tool is poor, and the iron chips cannot be discharged, resulting in the temperature generated during processing. . [0004] Contents of the invention [0005] The purpose of the present invention is to provide a forming chamfering knife, which can improve the chip removal effect of the forming chamfering knife, re...
