Abstract

The invention relates to a PCD blade for machining a small end hole of a connecting rod. The PCD blade comprises a blade body, a cutting edge is arranged on the blade body, a chip breaker groove is formed in the upper surface of the cutting edge and is of an L-shaped bent structure, the bent angle a of the chip breaker groove is 80 degrees, the distance L1 between the chip breaker groove and the outer edge of the cutting edge ranges from 0.05 cm to 0.1 cm, and the width L2 of the chip breaker groove is 0.57 cm. The flow direction of cutting chips can be controlled, the cutting chips can be broken more easily, the aluminum chips can be effectively blocked and discharged more smoothly, the service life of a cutter is prolonged, and meanwhile, the surface smoothness and the machining precision of a machined workpiece are ensured.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to a PCD blade for processing small head holes of connecting rods. Background technique [0002] The traditional cutting tool used to process the small head hole of the connecting rod is easy to wrap around the tool and the workpiece during processing, causing damage to the tool and damage to the processed surface, and may scratch the workpiece, thereby affecting the quality.
