Embodiment Construction

[0011] A groove-and-groove polishing method described in an embodiment of the present invention comprises the following steps:

[0012] 1) Cleaning: The proportion of cleaning solution is 100% solvent cleaning solution plus water, wherein the volume ratio of solvent cleaning solution to water is 1:8, put the workpiece into the basket and immerse it in the cleaning solution to wash off the surface oil, Shake the basket left and right for 1-2 minutes;

[0013] 2) Polishing: Put the abrasive into the drum. The material of the abrasive is yellow sand and ceramic polishing ball. The volume ratio of yellow sand to polishing ball is 1:4. After putting the workpiece in, the volume ratio of abrasive to workpiece is 2: 1; Their total height should not be higher than 1 / 3 of the drum; then add polishing liquid, add a box of polishing liquid for every 6000 workpieces, the size of the box is ∮6*5, and then add water to the drum at a distance of 5cm from the drum port , add the cover, assem...

Abstract

The invention relates to a groove polishing method, which comprises the following steps: 1) cleaning: placing a workpiece in a basket and immersing the workpiece into a cleaning solution for removing greasy dirt on the surface, lifting the basket and swaying the basket for 1-2 minutes; 2) polishing: placing a grinding material into a rotary drum, placing the workpiece into the rotary drum, covering the basket with a cover, and assembling the rotary drum onto a polisher, wherein the machining time is 40-50 minutes; and 3) rust preventing: washing the workpiece with flowing water immediately after the groove of the workpiece is polished and the workpiece is taken out, screening out the grinding material and dirty water, keeping the workpiece in an aqueous rust preventive for 5-10 seconds, and then taking out the workpiece. The groove polishing method has the benefits that not only does the groove of the workpiece become clean, but also the product quality is improved, and meanwhile, the method is lower in cost and higher in effect as compared with a method adopting a mesh belt furnace for workpiece groove treatment.

Description

technical field [0001] The invention relates to a tongue-and-groove polishing method. Background technique [0002] Polishing is a process generally required in the mechanical and electronic industries. The method is widely used. Most of the market uses ceramic polishing balls (round, cylindrical, diamond) for polishing, which is only suitable for large-scale workpieces. For small and miniature workpieces with high requirements, most heat treatment is changed to mesh belt furnace to reduce oil and impurities, but at the same time increase the cost. Generally, during heat treatment, there are too many oil stains and micro particles to be thrown away, which affects the quality. Contents of the invention [0003] The object of the present invention is to provide a tongue-and-groove polishing method, which overcomes the disadvantages of poor polishing effect, affecting product quality and high cost in existing products. [0004] The purpose of the present invention is to rea...
