Description

Technical Field

[0001] The utility model relates to the field of diamond tool preparation, in particular to a matrix structure of an ultra-thin precision slice. Background Art

[0002] At present, diamond slices have been widely used in the cutting of marble, concrete, granite, ceramics, glass and other hard and brittle non-metallic materials in the market; fine slices are a kind of diamond saw blade, which is mainly composed of diamond segments and matrix; during use, the diamond segments are mainly used to cut materials, and the matrix is ​​mainly used to support the cutting work of the diamond segments; diamond saw blades can process many objects, and fine slices are mainly used to process some materials with high requirements for cutting edge quality, such as artificial stone, marble, ceramic tiles, etc.; However, when the existing fine slices are sintered, the relatively thin matrix is ​​subjected to The internal stress cannot be released and the matrix is ​​prone to deformation. Moreover, since the matrix of the existing fine-slice cutting machine is generally an ultra-thin structure, it is relatively weak and easily deformed, resulting in a short service life of the fine-slice cutting machine. Once the fine-slice cutting machine is damaged, the entire saw blade will be discarded, resulting in a waste of materials and an increase in the cost of use. Therefore, flanges are welded on both sides of the matrix on the existing fine-slice cutting machine to enhance the structural strength of the matrix so that the matrix will not deform or shake when the fine-slice cutting machine is cut quickly. However, during the welding process of the flanges, the matrix is ​​prone to deformation, the welding work is difficult, and the structural strength of the matrix is ​​reduced, resulting in a poor feel of the fine-slice cutting machine.

[0003] In view of this, the designer has made in-depth considerations and actively researched, improved and tried to develop and design this case in order to address the many deficiencies and inconveniences caused by the imperfect design of the base structure of the above-mentioned precision slice.

[0027] The reinforcing ribs 23 in two adjacent grooves 22 on the same side of the utility model are staggered; the same fine tooth 21 is connected with two grooves 22 on the same side and one groove 22 on a different side, compared with the same fine tooth 21 being connected with six reinforcing ribs 23 in different directions, so that the structural strength of the fine slicing cutter head 2 is stronger and the service life is longer.
