The processing procedure of the facet gem generally comprises the following steps: cutting, preforming, gluing, looping, grinding and polishing to obtain the bright finished gem with facets. Among them, the most complicated and time-consuming links in the process of processing facet gemstones are the grinding and polishing links, which occupies nearly 85% of the time in the process of processing facet gemstones. When the traditional gem grinder and the octagonal hand are used for grinding and polishing facet gemstones, the grinding or polishing angle needs to be determined by means of the protractor, the included angle between the sticky rod and the grinding disc is visually observed by lifting the height of the octagonal hand table by using the protractor, and the complementary angle of the included angle between the sticky rod and the grinding disc is the grinding or polishing angle. Because the facet gem has a plurality of groups of facets with different angles, when one group of facets is ground or polished, a protractor is needed to adjust the grinding or polishing angle, and the steps are complicated. Taking the grinding and polishing of the crown part of a standard round drill type facet as an example, the grinding and polishing steps are as follows: 1. measuring the angle between the stick rod and the grinding disc by using a protractor, and determining the grinding angle of the kite surface; 2. grinding the kite surface; 3. determining a star facet angle using a protractor; 4. grinding the star facet; 5. determining an upper waist facet angle using a protractor; 6. grinding the upper waist facet; 7. determining the angle of the star facet by using a protractor; 8. polishing the star facets; 9. determining the angle of the kite surface by using a protractor; 10. polishing the surface of the kite; 11. determining an upper waist facet angle using a protractor; 12. and polishing the upper waist facet. Use the crown of the standard round drill type facet of the abrasive finishing as an example, at the standard round drill type facet precious stone in-process of abrasive finishing, need use the protractor through 8 times to adjust and confirm the angle that needs to grind or polish, adjust the angle of abrasive finishing at every turn, all need star anise platform of manual lift, it is comparatively consuming time, and confirm the angle of abrasive finishing through range estimation stick rod and mill contained angle, can have great error, consequently, it is comparatively consuming time to use star anise hand processing facet precious stone precision lower and adjust the angle of abrasive finishing, this also is the drawback of star anise hand.
At present, in the field of gem processing, although jewelry processing equipment with higher automation degree appears in the market, the equipment is complex in design and manufacture and high in price, the price is more than ten times of that of the traditional gem grinding equipment, and the maintenance difficulty and the maintenance cost are high. By looking up domestic and international data, no simple, fast, efficient and practical device capable of directly displaying the angle of the polished facet gem exists up to now, whether domestic or international.
In the grinding and polishing process of the existing gemstone grinding equipment, after each group of facets are ground, an octagonal table on a lifting support rod is adjusted, and an included angle between a sticky rod and a grinding disc is visually measured by using a protractor to determine a grinding and polishing angle.
