Turning/milling blade for machining dead-hard steel special-shaped part

Abstract

The invention discloses a turning / milling blade for machining a dead-hard steel special-shaped part. The blade comprises a blade body roughly in a right heptagonal shape. The blade body is provided with an upper surface, a lower surface and side faces; the geometric center of the blade body is provided with a fastening screw hole penetrating the upper surface and the lower surface, and the upper surface of the blade body and the crossing line of the side faces form a cutting part of the blade; the cutting part comprises a blade point located on the top corner of the right heptagon and cutting edges located on the side edges of the right heptagon; the cutting edges are sunken inwards in an arc shape to form fishtail-shaped cutting edges; the upper surface of the blade body extends inwards along the fishtail-shaped cutting edges to form a fishtail-shaped front blade face; and according to the structure, the problems that according to the profile manufacturing special-shaped face obtained after one-time postfire, the hardness of a workpiece is high, and it is required that wear resistance, blade breaking resistance, and structural precision of a tool are high, and the hard cutting performance of the tool is good are solved, and the technical problem that at present, one tool cannot meet the comprehensive machining requirement under the extreme condition is solved.

Description

technical field [0001] The invention relates to the technical field of cutting tools, in particular to a turning / milling blade for processing special-shaped parts of high-hardness steel. Background technique [0002] With the continuous emergence of new materials, new processes and complex structures of workpieces, higher requirements are placed on the performance of metal cutting tools. In order to reduce unnecessary costs, one-time processing, profiling processing and post-fire processing are more and more favored by manufacturers. [0003] At present, one-time post-fire profiling is mainly a new processing method proposed for the high-efficiency processing of complex parts. One-time processing requires the structural accuracy of the tool to meet the technical requirements before processing, that is, better anti-wear and chipping resistance, longer service life, and higher processing surface accuracy; profiling processing requires better structural accuracy of the tool. ...
