Embodiment 1

[0009] An all-powder ultra-thin diamond saw blade, the matrix element composition and mass percentage formula are: Cu, 45%; Sn, 12%; Co, 10%; Ni, 2%; Ag, 3%; S, 0.3%; P, 0.2%; C, 0.2%, the rest is Fe, according to the standard diamond content of 0.88 g / cm 3 For 100% concentration, the diamond concentration is 16%.

[0010] The manufacturing process of the full powder ultra-thin diamond saw blade as described above comprises the following steps:

[0011] A), material preparation---prepare the required raw and auxiliary materials such as matrix elements and diamond according to the design formula;

[0012] B) Mixing --- Stir the mixed powder and diamonds poured together, sieve with a sieve, pour the sieved powder into the mixer for mixing, and then sieve with a sieve after stopping the machine. Use a steel spoon to flatten the powder, and after visual inspection and review, enter the next process;

[0013] C), mold loading and pre-pressing --- check the bulk density of the mi...

Abstract

The invention relates to an all-powder ultrathin diamond saw blade, which comprises the following matrix elements in percentage by mass: 45 to 65 percent of Cu, 8 to 12 percent of Sn, 8 to 12 percent of Co, 2 to 4 percent of Ni, 2 to 4 percent of Ag, 0.3 to 0.5 percent of S, 0.2 to 0.3 percent of P, 0.2 to 0.3 percent of C, and the balance of Fe. Based on 100 percent of concentration of standard 0.88g/cm<3> diamond, the diamond concentration is 16 to 28 percent. By the technical scheme, the all-powder ultrathin diamond saw blade has the advantages that: 1, there is no matrix, and matrix waste is greatly reduced; 2, the thickness can reach 0.3 to 0.6mm; and 3, the height of a tool bit is 30 percent of the outer diameter of the saw blade, the service life of the product is long, the cutting efficiency is high, and a sawn joint is small.

Description

technical field [0001] The invention relates to a diamond saw blade, in particular to a full powder ultra-thin diamond saw blade. It belongs to the field of metallurgy technology. Background technique [0002] The existing carrier matrix saw blade is usually a 65Mn material steel sheet matrix in the middle. After the cutter head is used up, the steel sheet matrix cannot be reused, resulting in waste of steel. The conventional steel sheet 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...
