Sapphire refers to non red alumina, which has the characteristics of high sound speed, high temperature resistance, corrosion resistance, high hardness, high transmittance, high melting point, etc. It is a difficult to process material and is often used as a material for photovoltaic modules. So, what carving machine is used for precision processing of sapphire mirrors?

Precision engraving machine is a type of CNC machine tool, also known as engraving machine, punching machine, edging machine, irregular cutting machine, slotting machine, precision forming machine, mainly used for fine processing and irregular cutting of various types of glass. The technology is mature, characterized by small machine size, high processing accuracy, stable machine, fine finished products, fast processing speed, and high production efficiency.

CNC engraving is performed using the grinding wheel groove of the engraving machine, which grinds rough glass edges and removes excess parts; Chamfering and drilling sapphire glass raw materials with a drill bit to meet product requirements. Of course, there are other differences such as rotational speed and processing path. A specialized engraving and milling machine specially designed for sapphire crystal mirrors, optimized for sapphire glass and enhancing machine stability.

1. 3-zone design separates the processing area, electrical area, and maintenance area, effectively isolating dust.

2. The Y-axis adopts a double-layer design of stainless steel protective plate and accordion style protective cover, effectively preventing dust from entering.

3. The corner double door and safety door have a larger opening angle, making it more convenient to access workpieces.

CNC engraving is an important part of sapphire processing. Compared with metal, glass is brittle and fragile, so the cutting tools for glass CNC processing are different from those for metal aluminum alloy CNC processing. Carving and milling machines make up for the problems of poor rigidity, unreasonable structural design, and low protection level of traditional CNC machine tools. Traditional CNC machine tools cannot process sapphire mirrors, but carving and milling machines can process them well.
