Ceramic products are widely used in life, such as common ceramic bowls, vases, tiles, etc., but few people know that ceramic products are also widely used in the field of electric vehicles, new power transmission systems, solar energy and LED lighting. It is mainly used as a substrate, that is, a ceramic substrate. When ceramics are used in some precision devices, the processing requirements of ceramics are quite different from those of common ceramics in life. Taking cutting as an example, the basic requirements of ceramics in life are simple cutting, while high-precision industries require ceramics Cutting to achieve a certain precision and effect. This greatly increases the difficulty of processing ceramics. With the development of laser technology, laser micromachining technology has gradually been used in cutting, drilling, scribing and other processes of precision ceramics, and has shown unique technological advantages.
The laser equipment commonly used in ceramic cutting mainly includes the following: ultraviolet laser cutting machine, adjustable pulse width infrared laser cutting machine, picosecond laser cutting machine and CO2 laser cutting machine. Chuangxuan Laser currently mainly adopts imported ultraviolet laser cutting machine, Picosecond laser cutting machine and QCW infrared laser cutting machine are used to process ceramics, and the two types of equipment correspond to ceramic processing parts of different materials and thicknesses.
Ultraviolet laser cutting ceramics uses imported lasers, which are mainly suitable for the processing of hard ceramic materials below 1mm such as alumina, aluminum nitride, aluminum carbide, etc., and soft ceramics below 6mm such as sodium chloride ceramic cutting, magnesium chloride ceramic cutting, etc. For example, cutting thicker ceramics will form a taper and a certain degree of blackening. Picosecond laser cutting ceramics is currently a more suitable equipment. Picosecond laser cutting machines have the advantages of short time consumption and high power, and have very little impact on the contact energy of materials. And the cutting speed is faster, but relatively speaking, the price is slightly higher.
