Abstract

The invention discloses a copper alloy wire for ultrafine machining and a preparing method for the copper alloy wire. The copper alloy wire comprises a core material and a coating. The core material is prepared by raw materials including, by weight, 23-45 parts of copper, 22-40 parts of carbon, 1-4 parts of tungsten, 1.2-4.4 parts of silver, 4-11 parts of molybdenum, 1.3-2.4 parts of tin, 2.1-5.2 parts of chromium, 1.2-4.4 parts of neodymium, 3.3-3.5 parts of cerium, 3-6 parts of boron, 3-6 parts of phosphorus and 3-6 parts of oxygen. Piano wires coated with brass are added to manufacture the copper alloy wire, the tensile strength of the copper alloy wire is doubled, the high-tensile, high-strength and high-performance cutting is achieved, the number of steps of the preparation method is small, the production equipment is simple, products meeting the requirement are easily manufactured, scale and automatic production is easily achieved.

Description

Technical field [0001] The invention involves the field of copper alloy wires, which specifically involves a copper alloy wire and its preparation methods for ultra -precision processing. Background technique [0002] The principle of electrical spark processing is that in a certain medium, the phenomenon of electrostatic corrosion phenomenon of pulse spark discharge between tools and workpieces (positive, negative electrodes) is eroded from excess metal, thereby achieving the size, shape and surface quality of the partsWait for the scheduled processing requirements.Electric spark cutting processing is mainly used for mold manufacturing. It has also been increasingly widely used in the processing of models, cam, forming tools, precision small parts and special materials.In addition, when trying motor and electrical appliances, some parts can be cut directly with wires to save the time of stamping molds and shorten the trial system.Electric spark cutting and processing have outs...
