Embodiment Construction

[0041] Three batches of ultra-thin diamond circular saw blade substrates were prepared by using the manufacturing method described in the present invention. The base steel is 50Mn2V, and the chemical composition of the three batches of base steel is shown in Table 2. The design specifications (diameter and thickness) of the three batches of substrates are shown in Table 3. After the base steel is cut and blanked by plasma, it is quenched and tempered, followed by finishing turning, grinding, leveling and rolling. After fine calibration and fine grinding, finally check the technical indicators of the substrate. Quenching and tempering parameters are shown in Table 4, and the final inspection technical indicators of the matrix are listed in Table 5. Table 5 also includes the mechanical properties of the base steel leaving the factory.

Abstract

An ultra-thin matrix of circular diamond saw with 3-6.5 mm of thickness is prepared through blanking, machining, quenching, pressure tempering, levelling and grinding. Its advantages are high productivity increased by 10-20%, low energy consumption decreased by 30%, and high utilization rate of raw material (increased by 10-15%).

Description

technical field [0001] The invention belongs to the field of metal products, and mainly relates to diamond saw blades. Background technique [0002] Diamond saw blades, especially diamond circular saw blades, have been widely used in the cutting of non-metallic hard building materials (such as marble, granite, cement products, etc.). The diamond saw blade is composed of two parts: a diamond segment and a saw blade base. There are usually three methods for combining the diamond nodule and the matrix (steel): high-frequency welding, laser welding and sintering. [0003] Among the technical indicators of diamond circular saw blades, in addition to mechanical properties, stiffness, and flatness, the thickness of the saw blade is also a key indicator concerned by the non-metallic hard building material processing industry, because the thickness of the saw blade directly affects the The cutting and processing efficiency, energy consumption and utilization rate of raw materials (...
