Flexible passivating processing method for superhard cutting tool and flexible passivating processing device thereof

Abstract

The invention discloses a flexible passivating processing method for a superhard cutting tool and a flexible passivating processing device thereof. The flexible passivating processing method comprises the steps as follows: superhard or high-hardness grinding material is mixed with an aqueous phase according to a predetermined proportion to form a water-base passivating medium that is put in a container; a turbine impeller is arranged in the container; the turbine impeller drives the water-base passivating medium in the container to rotate towards the same direction; the superhard cutting tool is clamped by a clamp; a cutting edge of the superhard cutting tool is dipped into the water-base passivating medium in the container, and the clamp is led to drive the superhard cutting tool to rotate in the water-base passivating medium at the same time; the rotation direction of the clamp and the superhard cutting tool is opposite to that of the water-base passivating medium; and the flexible passivating treatment on the superhard cutting tool can be achieved through the friction which is generated by the reverse rotation of the water-base passivating medium relative to the superhard cutting tool. By adopting the flexible passivating processing method, the problem that in the prior art, passivating treatment is carried out on the superhard cutting tool can be solved effectively; and the flexible passivating processing method has the characteristics of simplicity and easiness in implementation.

Description

technical field [0001] The invention relates to the field of tool manufacturing in the machining industry, in particular to a flexible passivation treatment method for superhard material cutters and a flexible passivation device thereof. Background technique [0002] Knives usually require passivation. The traditional processing method is to insert the tool into the abrasive pile and stir, and during the agitation, the tool is rubbed against the abrasive to passivate the cutting edge of the tool. This passivation method is not easy to operate, and the passivation effect is not ideal. [0003] At present, there is no passivation machine designed and produced in China to passivate the knives. There are two types of tool passivation equipment abroad. One is Swiss gerber, which has a production history of more than 50 years; the principle of this passivation machine is to use a brush to add diamond abrasive paste through the worktable, the workpiece carrier and the rotation o...
