Abstract

The invention belongs to the technical field of a cutting wire saw, specifically relates to a diamond wire saw and a preparation method thereof. In the diamond wire saw provided by the invention, theintermediate core is tungsten, the surface layer is covered with a metal plating layer or a resin layer, the surface of the metal plating layer or the resin layer is fused with diamond particles. Thepreparation method is as follows: a tungsten wire is combined and pulled by multi-pass sliding drawing and non-sliding drawing to obtain a tungsten wire with a diameter of 0.008-0.065mm; and then, thedrawn tungsten wire passes through an electrolyte containing diamond particles to obtain an electroplated diamond wire saw; or the above drawn core wire passes through a resin solution containing diamond particles to obtain a resin diamond wire saw after being cured. The diamond wire saw with the core body prepared by the invention has a diameter of 0.01-0.085mm and a strength greater than or equal to 4000 MPa, so the diamond wire saw can effectively improve the cutting quality and cutting efficiency in the application aspect of the cutting line.

Description

technical field [0001] The invention belongs to the technical field of cutting wire saws, and in particular relates to a diamond wire saw and a preparation method thereof. Background technique [0002] Due to the fixed abrasive grains on the surface of the diamond wire saw, long wire life and high cutting efficiency, the diamond wire saw is widely used in the cutting of semiconductor materials such as silicon crystals. [0003] With the development of competition in the photovoltaic industry, diamond wire saws are required to have a thinner diameter, higher strength, and higher toughness. However, the core body of the current diamond wire saw is made of carbon steel, and the strength and plasticity indicators can no longer meet the higher requirements. Therefore, it will be of great significance to find other materials as diamond wire core wires. [0004] Due to its excellent heat resistance and mechanical strength, tungsten wire is expected to be used as the inner core ma...
