At the forefront of hard and brittle material processing, marble and diamond are widely used in electronics, aerospace, medical and other fields due to their unrivaled hardness and unique properties. However, its super-hard characteristics also bring great challenges to processing, and traditional processing methods are often difficult to meet the demand for high-precision, high-quality cutting. GW Laser QCW quasi-continuous fiber laser opens up a whole new path for cutting hard and brittle materials, and brings an unprecedented processing experience.

Pain points of traditional processing of hard and brittle materials

Traditional marble cutting methods, such as tool cutting, cutting speed is extremely slow, seriously restricting productivity. Cutting tools in the cutting process is very easy to wear, frequent replacement of tools not only increase the cost, but also difficult to ensure the consistency of cutting accuracy. Moreover, the mechanical stress generated during cutting often leads to cracks in the marble plate, greatly affecting product quality. Waterjet cutting although to a certain extent to reduce the thermal impact, but the high cost of equipment, running a large amount of water and abrasive consumption, the high cost of maintenance, cutting speed is relatively slow, for complex patterns of cutting accuracy is difficult to control.

GW Laser QCW Quasi-Continuous Fiber Lasers

GW Laser QCW quasi-continuous fiber lasers (such as YLP-QCW-600/6000-W) achieve “zero damage, high efficiency and high consistency” in the processing of hard and brittle materials through the technology of “ultra-fast modulation + precise energy control”. Its cutting precision is excellent, and it can output a laser beam with high energy density and focus it precisely. The cutting gap is narrow and even, and the cutting edge is smooth and even, which can meet the strict requirements for precision of high-end marble products. Both fine lines and complex patterns can be accurately rendered. In terms of cutting speed, there is a qualitative leap compared with the traditional way. High-energy laser beam can quickly make the marble irradiated parts of the material vaporization, to achieve rapid cutting, significantly shorten the processing time, improve production efficiency, and create higher economic benefits for the enterprise.

The heat-affected zone of the laser is extremely small. Laser cutting is non-contact processing, the heat generated during cutting is quickly taken away by the vaporized material, the thermal effect on the marble plate is minimal, the plate will hardly be deformed or discolored due to heat, and the original physical and chemical properties will be maintained to the maximum extent to ensure the stability of product quality. From the point of view of operating costs, GW Laser QCW quasi-continuous fiber laser has significant advantages. It eliminates the need for frequent tool changes and does not consume as much water and abrasive as waterjet cutting. The laser's high electro-optical conversion efficiency, low energy consumption, and simple post maintenance reduce equipment downtime and maintenance costs, lowering the overall operating costs of the enterprise.

In the field of marble and diamond, GW Laser QCW quasi-continuous fiber laser is widely used. In the processing of marble decorative plates, it can accurately cut the plates into various sizes and shapes to meet the needs of different decoration styles, splicing tightly to enhance the decorative effect. In the engraving of marble handicrafts, it can engrave delicate textures and vivid patterns on the surface with high precision, which injects vitality into the handicraft industry. In addition, in diamond cutting, it can be used as an auxiliary tool to reduce the hardness of diamond by laser heating first, and then combined with other cutting methods to reduce the difficulty of cutting, improve efficiency and quality, and broaden the scope of diamond applications.

GW Laser's QCW quasi-continuous fiber laser is highly competitive in the marble cutting field due to its outstanding advantages in cutting accuracy, speed, heat-affected zone and cost. Its successful application in marble and diamond and other related fields opens up a new direction for the development of the industry. With continuous technological innovation, GW Laser is expected to play a greater role in stone processing and more fields, and to promote the continuous progress in the field of marble and diamond processing.
