Ceramic products are widely used in life, and can be divided into three categories: structural ceramics, tool ceramics and functional ceramics. Mainly used in electronic products, generally integrated in electronic circuits, which are quite different from ordinary tool ceramics.

Common ceramic products in the electronics industry are: alumina ceramics, zirconia ceramics and silicon nitride ceramics. So how are these ceramics cut? I will introduce it to you in detail today.

Ceramic products are widely used because of their high melting point, high hardness, high wear resistance, oxidation resistance, etc., but it also greatly increases the difficulty of cutting ceramic products. The traditional cutting method is to use diamond saw blade cutting and water jet cutting, etc., but for the 3C electronics industry, its accuracy and efficiency cannot meet the development of the process. Therefore, many ceramic manufacturers have introduced laser cutting technology and used laser cutting technology. The cutting machine performs cutting, scribing, punching, etc. of ceramic products.

Ceramic laser cutting machine has high power density and good directivity, and is currently the most popular ceramic punching and cutting equipment. The surface of the ceramic product is irradiated by a high-energy-density laser beam to melt and vaporize the material. The laser heat-affected area is extremely small, and it is especially suitable for precise drilling of small-sized and high-density products such as electronic components and semiconductor components. The achievable aperture is between 0.05 and 0.2 mm. Different material thickness and power configuration of the model affect the aperture size.

Advantages of ceramic laser cutting machine:

(1) Using fiber laser, high precision, fast speed, narrow slit, smooth cutting surface without burr.

(2) Non-contact processing method, no mechanical stress, no scratches on the surface of the object

(3) The slit is narrow, the heat affected zone is small, the local deformation of the workpiece is small, and there is no mechanical deformation.

(4) Flexible and convenient, easy to use, can process any graphics, and can also cut pipes and other special-shaped materials.
