Method for polishing and grinding hydrant drill end and special polishing grinder

Abstract

The invention is concerned with simulation diamond end face polishing-grinding machining method and the expert polishing-grinding machining. Set stuff and put molding plastics-absorption tray on fixture tray and make the concave face of plastics-absorption tray upside, and the simulation diamond adsorbs on the convexity of the bottom to plastics-absorption tray. Set plastics-absorption tray on the polishing-grinding machining and mill the tine end of simulation diamond on calm millstone. The polishing-grinding machining relates rack with a level millstone at its middle, and there are two level trays. They are centrosymmetric to the axis of millstone on top of millstone and have plastics-absorption tray on them. There is up and down equipment for tray on top of level tray which connecting with two turning axes on two sides of millstone with level rack, and the other end of turning axis has running equipment of turning axis. It has large machining amount of each time, high produce efficiency, good ratio to excellent stuff, long work time, easy operation without waste of material.

Description

technical field [0001] The invention relates to a method for grinding and polishing the end face of a rhinestone (artificial diamond) and a grinding and polishing machine specially used for the processing method. Background technique [0002] Rhinestones are man-made diamonds, which are important supporting materials for jewelry, footwear, handicrafts, etc., and have a huge market. The grinding and polishing process of rhinestones is as follows: the artificial crystal ball blank is first processed by facet grinding and polishing to form a multi-facet shape as shown in Figure 1, and then the end face is ground and polished to form a diamond shape as shown in Figure 2 , and then silver-plated and coated with a protective coating on the bottom of the rhinestone to give it a diamond-like reflective effect. The existing end face grinding and polishing processing equipment is to continue the design idea of ​​using the edge face grinding and polishing proce...

AI Technical Summary

Problems solved by technology

The existing end face grinding and polishing processing equipment is to continue the design idea of ​​using the edge face grinding and polishing processing equipment. The entire aluminum drainage drill after the edge face grinding and polishing process is directly placed on the flat grinder for end face grinding and polishing. However, because the end face grinding and polishing There is a big difference between processing and facet grinding and polishing. The processing steps are relatively simple and have high self-adaptive requirements for grinding and polishing rhinestones and tooling.

Therefore, there are problems such as low processing efficiency, low yield rate, high material waste rate, and low service life of processing equipment tooling when using existing end face grinding and polishing processing methods and equipment to process water drills.
