Problems solved by technology

[0005] The technical problem to be solved by the present invention is to provide a semi-circular arc sintered saw blade substrate and processing technology. The new semi-circular arc sintered saw blade can well solve the deficiencies of the traditional sintered circular saw blade in processing deformation, pressing molds and processing costs. Unfavorable aspects of staying high; at the same time, it effectively solves the problems of stress release and thermal expansion and extension

Embodiment 2

[0056] In the present invention, the processing technology of the semi-circular arc sintered saw blade base comprises the following steps:

[0057] Step 1, laser cutting and blanking: use laser cutting to cut and blank the semi-circular saw blade base 1 to a circle of φ312, and form a base disc;

[0058] Step 2, coarse grinding: Use concentric circular plane round table grinder to finely process both sides of the base disc, if the material is deformed, apply grinding and leveling to a thickness of E: 3.97;

[0059] Step 3, second calibration: finely level the double-sided planes of the base circular plate with the thickness ground to the size to the double-sided flatness ≤ 0.15, the double-sided end jump ≤ 0.15, the internal stress value is biased but not too large can;

[0060] Step 4, fine reaming: finely ream the base circular plate that has passed the leveling process to the center hole of φ25.4 in conventional applications through high-precision vertical drilling. The a...

Abstract

The semi-arc sintered saw blade base body comprises a semi-arc saw blade base body, and a plurality of mounting holes are formed in the positions, close to an inner arc, of the semi-arc saw blade base body; a plurality of evenly-distributed water grooves are machined in the outer ring of the semi-arc saw blade base body. A plurality of tooth heads with concave-convex surfaces are distributed on tooth end surfaces formed between two adjacent water tanks; two-sided steps which are symmetrically arranged are machined on the tooth end face which is a certain length away from the outer ring. According to the novel semi-arc sintered saw blade, the defects that the machining deformation of a traditional sintered saw blade is insufficient, and the pressing die and the machining cost are high can be well overcome; and meanwhile, the problems of stress release and thermal expansion extension are effectively solved.

Description

technical field [0001] The invention relates to a semicircular arc sintered saw blade base body and a processing technology, and belongs to the technical field of diamond sintered circular saw blade manufacturing. Background technique [0002] Sintered diamond saw blade is a kind of cutting tool, which is widely used in cutting various building materials, ceramics, ceramic tiles, glass, granite, marble, jade and masonry concrete and other materials. Sintered diamond is currently the hardest substance. It has been widely used in many industries. In the market, it has great advantages in use. Compared with other similar products, it is more popular with users. favor. At present, the main processing methods of diamond tools are divided into four types, namely thin film coating, thick film diamond welding, diamond sintering and single crystal. Different processing methods produce different types of cutting tools, and they play different roles when used. It can cut a variety o...
