Abstract

The invention relates to an all-power ultrathin diamond saw blade. The formula of the all-power ultrathin diamond saw blade comprises, by weight, 45-65% of Cu, 8-12% of Sn, 8-12% of Co, 2-4% of Ni, 2-4% of Ag, 0.3-0.5% of S, 0.2-0.3% of P, 0.2-0.3% of C and the balance Fe. When the content of diamond is 0.88g / cm<3>, the concentration of diamond is 100%; the concentration of diamond is 16-28%. By employing the above technical scheme, the all-power ultrathin diamond saw blade is advantaged in that 1, the diamond saw blade does not have a substrate, and waste of the substrate is greatly reduced; 2, the thickness of the all-power ultrathin diamond saw blade can reach 0.3-0.6mm; 3, the height of the cutter head reaches 30% of the external diameter of the saw blade, and the all-power ultrathin diamond saw blade is long in service life, high in cutting efficiency and small in saw kerf.

Description

technical field [0001] The invention relates to the technical field of metallurgy, in particular to a mixed metal ultra-thin diamond saw blade. Background technique [0002] The existing carrier matrix saw blade is usually a 65Mn material steel matrix in the middle. After the cutter head is used up, the steel matrix cannot be reused, resulting in waste of steel. The conventional steel matrix accounts for 10%-15% of the entire saw blade material cost. The cost ratio of the sound-absorbing steel sheet substrate and the sandwich-shaped steel sheet substrate is higher. [0003] Due to the limitation of steel quality, the thickness of conventional steel substrate saw blades cannot be made too thin. Generally speaking, for a saw blade with an outer diameter of Φ100mm, the thickness of the substrate is 0.8mm, and the blade head is 1.0mm, which has reached the limit. Due to the high thickness of the saw blade, the width of the saw kerf is up to 1.0 mm, which results in a large los...
