Problems solved by technology

Among them, the magnetorheological polishing method requires a special magnetic liquid, which needs to be imported from abroad, and consumes a lot; the jet-assisted polishing method is still in the experimental stage, and the technology is immature, so it cannot be used in industry; the grinding force of ion beam polishing is too low. It is only suitable for finishing, and the processing efficiency is low. The finishing of a component surface needs to be processed to a high precision before it can be effective. Therefore, it is difficult to meet the polishing of large-diameter components.

Embodiment

[0028] Such as figure 1 As shown, this embodiment provides an adsorption flow grinding and polishing method, which does not require a grinding head, and the friction force generated by the flow of the starch mixture and the surface of the processing element replaces the grinding force to perform grinding. Specifically, the polishing method includes the following steps:

[0029] 1. Soak the component to be processed 1 into the starch mixture 2, and the liquid surface submerges the processing component;

[0030] 2. Extend the adsorption tube 4 connected with the adsorption instrument 3 below the surface of the starch mixture, and the nozzle of the adsorption tube is 0.5mm to 1mm away from the processing element. Preferably, the nozzle of the adsorption tube is 1mm away from the processing element; the adsorption instrument is a vacuum cleaner. Or suction pump, power 1500W, vacuum suction 1900l / min, air flow 53L / S, adsorption tube diameter 36mm;

[0031] 3. Fix the adsorption t...

Abstract

The invention discloses an adsorption flow grinding and polishing method which mainly solves the problems that an existing polishing method is extremely low in automation degree, complex to realize, low in machining efficiency and the like. The adsorption flow grinding and polishing method comprises the following steps that (1) an element to be machined is soaked into starch mixed liquor and the element to be machined is immersed in the liquor face; (2) an adsorption pipe connected with an adsorption instrument is stretched into the position under the starch mixed liquor and a pipe orifice of the adsorption pipe is 0.5mm to 1mm away from the element to be machined; (3) the adsorption pipe is fixed, the adsorption instrument is stated, the starch mixed liquor is quickly adsorbed away, the starch mixed liquor flows, friction between the starch mixed liquor and the surface of the element to be machined is generated, so that grinding force is produced, and polishing machining of the element to be machined is realized. The starch mixed liquor is composed of water, starch and polishing powder, wherein the mass ratio between the water, the starch and the polishing powder is 1:4:1. A grinding head is not needed in the adsorption flow grinding and polishing method, the friction force is produced between the starch mixed liquor and the surface of the element to be machined through flow of the starch mixed liquor, the friction force can replace grinding force for conducting grinding machining, and the adsorption flow grinding and polishing method is convenient to realize and low in cost.

Description

technical field [0001] The invention relates to a polishing method, in particular to an adsorption flow grinding and polishing method. Background technique [0002] The polishing method is mainly divided into a grinding polishing method with a grinding head and a polishing method without a grinding head. At present, double-sided grinding and polishing machines and multi-axis polishing machines generally require grinding heads to participate in polishing. This type of equipment cannot process aspheric surfaces, off-axis, free-form surfaces, and fairings with large aspect ratios, and requires a lot of auxiliary materials for processing. The dependence on the grinding head is large and the grinding head is easy to deform, so it is difficult to control the surface shape of the component; and because of the overall contact, it is difficult to repair the surface shape. Among them, the disc surface used by the multi-axis grinding and polishing machine is mostly an asphalt disc. Wh...
