Method and apparatus for processing composite abrasive material by overlapped vibration

Abstract

The invention discloses a method for processing layered vibrating composite abradant, which comprises: axially processing low-frequency and ultrasonic vibrations on the plated diamond at the same time when processing rigid material, to layer said two vibration, and processing a axial pressure p on the device; using water as medium to guide the plated diamond and dissociate abradant into treating section at the same time. Said treating device comprises a piezoelectricity heat exchanger, the first bolt, an amplitude rod, the third bolt, and a device for plating diamond, wherein, the amplitude rod via the flange disc and the second bolt at itself note to connect the cover of piezoelectricity heat exchanger; a workbench and a low-frequency vibrator are arranged under the diamond plating device, while the workbench has a clamp. The invention can reduce the processing force (only 1 / 6-1 / 8 of traditional ultrasonic processing force) and the inner stress of work-piece; improve the processing accuracy to 0.001-0.003mm, with better integration and lower cost.

Description

technical field [0001] The invention belongs to a grinding processing method, in particular to an overlapping vibration composite abrasive processing method and device. Background technique [0002] With the rapid development of science and technology and industrial production, hard and brittle materials represented by ceramics, hard alloys, neodymium iron boron, silicon, germanium, ferrite, zirconia, glass ceramics, hardened steel, chrome plating, etc. There is no end to it, and the application fields are more and more extensive. Traditional processing methods have always had major problems such as low processing efficiency, easily broken workpieces, high energy consumption, poor processing quality, and failure to achieve many design requirements, which have long troubled and affected the production of the factory. Factories urgently need to solve the problem of high-efficiency precision machining of hard and brittle materials. [0003] 1. Precise machining of special-sha...

AI Technical Summary

Problems solved by technology

[0019] (1) Tool life is short;

[0020] (2) The machining accuracy is low, only 0.05-0.08mm

[0021] (3) The force exerted by the tool on the workpiece is relatively large, resulting in an increase in the internal stress of the workpiece during processing, which is prone to abnormal rupture

[0022] (4) The thickness of the workpiece ribs should be increased to 4-5 mm, which cannot meet the maximum lightweight requirements of the workpiece;

[0023] (5) Low processing efficiency

[0024] (6) High processing cost
