Rigid superhard material precision cutting tool passivating machine

Abstract

The invention provides a rigid superhard material precision cutting tool passivating machine, and belongs to the technical field of cutting tool manufacturing. The problem that existing passivating machines are poor in passivating effect is solved. The rigid superhard material precision cutting tool passivating machine comprises a machine base and a servo motor. A machine frame is arranged on the machine base. A columnar rotary plate of which the axis is horizontally arranged is arranged on the machine frame. A plurality of rotary shafts around the axis of the rotary plate are arranged on the rotary plate in a penetrating mode. A clamping is connected to the rotary shaft. The servo motor drives all the rotary shafts to rotate through a driving mechanism. A horizontal guide rail is arranged on the machine base. A supporting plate is arranged on the guide rail. A tubular passivating barrel arranged coaxially with the rotary plate is arranged on the supporting plate. A circle of radial bristle brushes protruding radially is arranged on the inner wall of the passivating barrel. A mounting plate is connected to the end, away from the rotary plate, of the passivating barrel. An annular axial bristle brush protruding axially is arranged on the inner end face, facing the rotary plate, of the mounting plate. The rigid superhard material precision cutting tool passivating machine has the advantages of being low in manufacturing cost, high in rigid superhard material precision cutting tool passivating efficiency and good in passivating effect.

Description

technical field [0001] The invention belongs to the technical field of tool manufacturing, and relates to a passivation machine, in particular to a hard superhard material (hard alloy, polycrystalline diamond and cubic boron nitride) made of high-precision hard superhard materials. Passivation machine for cutting edge quality of precision cutting tools. Background technique [0002] Tool edge passivation technology is a problem that has not been paid attention to by people, but it is very important to improve the quality of superhard material precision tool edges. After passivation, the tool has a great change in performance. Lifespan can be increased by 20-30%. This passivation is also an important process after precision grinding and before coating. The passivation technology and method of precision tools is a technical bottleneck that we urgently need to solve, and it is also a technical bottleneck that all superhard tool manufacturers in the world are concerned about. ...

AI Technical Summary

Problems solved by technology

The passivation machine produced in Germany is mainly used for the deburring of hard alloy precision tools and the polishing and passivation of coated metals. This principle cannot be used for the passivation of superhard precision tools. There are several major disadvantages: 1. The method is too violent, and the passivation value is uncontrollable; 2. This method cannot achieve the purpose of passivating the edge of the tool, and the passivation medium will damage the edge of the tool; 3. At present, no one has found a suitable passivation medium; 4. Due to Due to the particularity of the material and shape of superhard tools, there is no way to use this method to passivate precision tools in superhard materials

[0005] The above-mentioned flexible passivation device for superhard material knives can passivate precision knives, but the structure is complex, and the manufacturing cost is still relatively high, although it is cheaper than German passivation equipment, and only one tool can be processed at a time , the processing efficiency is not high. In addition, professionals can mix water, superhardness or high hardness abrasives according to the actual precision tools, which is inconvenient to use.
