Machining technology for crystal glass with pattern embossments

Disclosed is a machining technology for crystal glass with pattern embossments. The machining technology comprises the following steps that A, materials are prepared; B, coarse grinding is performed, wherein rough surfaces or incomplete portions of the crystal glass are rubbed away to obtain a coarse ground crystal glass product with the complete and smooth surfaces; C, ultrasonic molding is performed, wherein a workpiece is placed into a working area of ultrasonic equipment, the end face of a molding die is utilized for ultrasonic vibration, and a grinding material suspension impacts and polishes the surfaces of the coarse grinding crystal glass product to obtain a coarse crystal glass finished product with the edge pattern embossments; D, cleaning is performed, wherein residues on the surface of the coarse crystal glass finished product are removed; E, surface polishing treatment is performed, and cleaning is performed to obtain the crystal glass finished product with the smooth pattern embossments. According to the machining technology for the crystal glass with the pattern embossments, ultrasonic molding machining and surface polishing machining are adopted, and pattern decorations with radians can be machined on the surface of the crystal glass, so that the decoration effect of the crystal glass is improved, the technology is simple and convenient to implement, and precision is high.
