Problems solved by technology

However, the common high-feed turning inserts on the market are mostly designed with ISO standard contours. During the high-feed cutting process, the blade often causes a sharp decline in the surface quality of the workpiece while improving the processing efficiency; at the same time The chip breaker of the insert has a simple structure, and most of them are designed as a no-edge inclination structure or a simple straight-line inclination angle structure, which has limited ability to control chips. The entanglement and impact of chips will also affect the surface quality of the workpiece and increase the wear of the tool. cause an increase in production costs

Abstract

The invention provides an indexable cutter blade for turning, which belongs to the technical field of a machining cutter, and solves the problems that the existing turning cutter blade is limited in control capacity for cuttings and the machined product is low in precision. The indexable cutter blade for turning comprises a cutter blade main body with an upper surface, a lower surface and side surfaces, wherein a cutting edge part is respectively formed between the two adjacent side surfaces and the upper surface, each cutting edge part is provided with a cutting edge angle, two sides of each cutting edge angle are respectively provided with a finishing edge, a cuttings accommodating groove is formed between two finishing edges, two sides of the cuttings accommodating groove are provided with cuttings breaking tables which are symmetric to each other, and the cuttings breaking tables are protruded upwards along the cutter blade main body and connected with the finishing edges. The indexable cutter blade has the advantages of higher cutting efficiency, good cuttings breaking effect and the like.

Description

technical field [0001] The invention belongs to the technical field of processing tools, and relates to a machining blade, in particular to an indexable blade for turning. Background technique [0002] In the international market, the use of high-feed turning tools is very common. It has been widely used in machining industries such as molds, wind power and automobiles. The biggest feature of this kind of blade is that it can perform high-feed cutting to achieve processing efficiency. improvement. However, the common high-feed turning inserts on the market are mostly designed with ISO standard contours. During the high-feed cutting process, the blade often causes a sharp decline in the surface quality of the workpiece while improving the processing efficiency; at the same time The chip breaker of the insert has a simple structure, and most of them are designed as a no-edge inclination structure or a simple straight-line inclination angle structure, which has limited ability...
