The present invention relates to a cutting equipment, in particular to a cutting tool set for glass cutting.

Check that the cutting principle of glass materials is very different from the cutting of general craft materials. Because the hardness of glass is extremely large, it must rely on special tools with a hardness greater than that of the glass to make cuts on the surface first, and then use the cuts as a fulcrum. A stress is applied to both sides of the cut to make the glass divided into two along the cut, and then by repeating the above operations, the glass can be cut into the required shape and size, and the glass cutting tool Groups are especially common in the manufacturing process of display panels in the optoelectronics industry to cut a large area of mother glass into glass of required size. Therefore, the cutting tool group plays a very important role in the glass substrate cutting process. It will directly affect the quality and yield of subsequent products.
