Abstract

The invention relates to a metallic-bond complicated-surface diamond saw blade and a 3D printing and making process thereof. According to the invention, a latticed segment working layer is formed by distribution of solid bodies and blank bodies along radial and circumferential directions, and the latticed segment working layer, a segment welding layer and a saw blade base body jointly form a saw blade whole body. In the segment welding layer, the latticed segment working layer is printed in a 3D manner by adopting a laser sintering process. According to the invention, in work, due to existence of gaps, chippings produced in grinding can be effectively removed, so that an effect of cleaning a grinding surface can be achieved; and the saw blade is prevented from carrying out secondary grinding on the chippings, so that the working efficiency is improved. Meanwhile, heat produced in grinding can be quickly dissipated through the gaps, so that failure of a working surface caused by high temperature is avoided, and the service life of the saw blade is prolonged. By adopting a 3D printing manner, printing can be performed just by setting parameters on a computer, thus ensuring precision and dimension requirements and improving production efficiency.

Description

technical field [0001] The invention mainly belongs to the field of mechanical processing, utilizes 3D printing technology, and particularly relates to a diamond saw blade with a complex profile of a metal bond and its 3D printing manufacturing process. Background technique [0002] Intelligent 3D printing technology does not need to make molds, not only can obtain complex special-shaped structure products, but also has fast production speed and high precision. The conventional method of making metal-bonded diamond saw blades uses a mold to make the whole process, and it is difficult to manufacture complex structural nodes, especially the complex grid-shaped nodes mentioned in the present invention; in the process of traditional mold charging and sintering, there is no Adopting advanced manufacturing technology, relying on manual operation, the accuracy is very limited; the labor intensity is high, it is easy to cause material waste, and the production efficiency is low, whi...
