Mesin Wire Cut: Wire Cut EDM

Application of Wire cut EDM

　　Our company's products adopt the application of "discharge machining" principle, combined with automatic control and microcomputer based mechanical and electrical integration. The machine is usually used molybdenum wire as the tool electrode, in the high frequency pulse voltage, using liquid medium was formed in the spark discharge breakdown, in the spark channel instant of great amount of heat, the workpiece surface of metal melting and gasification, and the common action of the liquid medium, and the metal is rapidly eroded in addition to down. The workpiece in the numerical control device or computer control automatically according to the program to determine the trajectory of movement, and finally get the required shape of the workpiece.

Main use of wire cut EDM:

processing all kinds of precision molds: die and compound die, etc.

Powder metallurgy die and die casting die, etc.

Extrusion die, plastic mold, shoe mold, etc.

Processing of all kinds of disk parts: such as gear, sprocket, cam, etc..

Processing all kinds of precision parts and samples, etc.

Processing all kinds of special materials, all kinds of conductive material, hard alloy, titanium alloy, diamond, especially rare precious metal cut off, all kinds of conductive body of complex cavity and curved surface processing.

Wire Cut EDM is mainly used in die manufacturing, in the model, cam, forming tool, precision small parts and special materials processing and has also been widely used in the market. In addition, in the trial production of motor, electrical and other products, it can be directly used to cut some parts of the wire, eliminating the manufacture of stamping die time, shorten the trial cycle.

The wire cut EDM has the characteristics of high machining accuracy, high finish and fast cutting speed. This paper describes the classification of the electric spark wire cutting machine, the appearance design of the machine tool is elegant, structural characteristics, and has a strong practical function. Machine protection equipment is also complete and reliable, in line with the relevant state departments on the safety of machine tools and general provisions of the provisions and requirements.

Now wire cutting technology development has become clear, in maintaining the reciprocating wire cutting advantages, continuous exploration and research, the new method and new theory used in the new system, presumably will be more stable, practical, simple and convenient. CNC EDM wire cutting machine consists of three parts: mechanical, electrical and working fluid system. The mechanical part is the foundation, its precision directly affects the accuracy of the machine tool, and also affect the electrical performance of the full play. The lathe bed is usually a box type structure, as a platform to provide installation components, so closely related to the precision of the machine tool. Lubrication system is used to relieve the mechanical wear and improve the mechanical efficiency and reduce the loss of power, cooling, reducing noise and vibration absorption, corrosion inhibition effect. The electrical part includes machine tool circuit, driving power supply, pulse power supply and control system. About electric spark wire cutting machine safety rules of the introduction, the working fluid system is generally composed of working fluid box, working fluid pump, liquid inlet pipe, liquid return pipe, flow control valve, etc.. The main function is to concentrate discharge energy, take away the heat to cool the electrode wire and the workpiece, the removal of corrosion products, etc..
