This invention provides a method for manufacturing a diamond wire saw for cutting silicon carbide single-crystal substrates. First, impurities are removed from the diamond micro-powder abrasive. During the abrasive application process, the abrasive density *a* on the steel wire is monitored in real-time via images and videos, and the feeding rate of the diamond micro-powder abrasive in the feeding container is controlled accordingly, achieving a first-step closed-loop control. In the subsequent nickel plating thickening process, the concentricity of the thickened layer on the steel wire and the continuous stability of its thickness are controlled. Before winding, the wire saw diameter *d* is measured using a laser method. Based on the mapping relationship between the wire diameter *d*, abrasive density *a*, and plating thickness *c*, a second closed-loop control is implemented for the entire wire saw production process. The two closed-loop controls operate nested together, ensuring precise control throughout the entire process. The diamond wire saw obtained by this method exhibits high continuous stability in various performance indicators, ensuring good process stability during the cutting of single-crystal silicon carbide substrates, thereby reducing cutting risks.
