The Choice for the Diamond Wire Base Material

The choice of the base material of the diamond wire saw is mainly determined by the mechanical properties of the wire and the electrochemical properties of the material. The diamond wire saw wire is wound around a set of guide wheels during the process of cutting and processing the workpiece, wherein the take-up and pay-off wheels complete the task of take-up and pay-off respectively.

During the processing of the diamond wire saw, the diamond wire does high-speed movement in a reciprocating manner, and a certain force is applied to the workpiece to make it perpendicular to the wire, and the cutting and plowing functions of the diamond particles indicated by the wire are fixed to achieve the process of manufacturing electroplated diamond wire saws and the study of their performance were carried out on the removal of the workpiece materials, and the wires were arranged on the guide pulley at regular intervals. Therefore, the wire base must meet the characteristics of high tensile strength. If the wire is broken, the entire cutting process will be stopped, resulting in huge economic losses. In addition, since the wire is wound on the guide wheel in a row and a row while cutting the workpiece, the wire must have good flexibility. Moreover, in order to increase the utilization of the material and reduce the loss of the kerf, the diameter of the wire must be reduced as much as possible while satisfying the tensile strength and flexibility.

At present, the commonly used saw wire base materials are stainless steel wire, piano wire, and copper-plated high-carbon steel wire. Material strength is high, but vibrations are easily generated during the cutting process, affecting the surface accuracy of the material processing surface. The diamond wire saw company's base material is not conductive, so it can not be used directly during electroplating, but it can be coated with a layer of metal on the surface of the base material through a certain process, and then electroplating. Since the manufacturing process is complicated, such materials are rarely used. Stainless steel wire tensile strength, flexibility, wear resistance composite requirements, but in the production process of stainless steel wire through hot pressing, welding, heat treatment and other processes, in the wire surface will produce a layer of dense oxides, such as nickel oxide, Chrome oxide, etc., increases the difficulty of pretreatment. The tensile strength, flexibility, wear resistance and service life of the piano wire meet the requirements, and chromium, nickel and other elements are not included in the body material. The pretreatment is simple, but the price of the piano wire is expensive, and the electroplated diamond wire is added the saw manufacturing costs. Copper-plated high-carbon steel wire on the surface satisfies the tensile strength, flexibility, wear resistance and service life of the wire, has the similar mechanical properties of the stainless steel wire, and has advantages that other base materials do not have. Copper-plated high-carbon steel wire the surface is coated with a layer of metal to avoid rusting of the high-carbon steel wire, which reduces the difficulty of pretreatment. After the copper plating on the steel wire, there is a layer of metal copper between the steel wire substrate and the nickel layer, which improves the steel wire substrate and the nickel layer. The copper is relatively soft with respect to iron, which increases the binding force and flexibility of the steel wire.
