PRECISION WIRE EDM MACHINING

PRECISION WIRE EDM MACHINING

Wire cutting is a precision machining method that utilizes the principle of electrical discharge to remove materials. It uses a continuously moving metal wire as an electrode to generate electric sparks between the wire and the workpiece, and cuts various hard and complex shaped metal materials through electrocorrosion.
Wire cutting is particularly suitable for processing hard materials and complex shaped parts, such as precision molds, small hole slots, narrow seams, arbitrary curves, etc. It has the advantages of small machining allowance, high precision, and strong adaptability. Due to the small diameter of the electrode wire and almost no loss, it is suitable for processing high-precision, small batch, and complex shaped products, widely used in mold manufacturing, precision machinery, electronics, aviation, medical and other fields.

WIRE EDM MACHINING SOLUTIONS

Wire cutting is particularly suitable for manufacturing precision parts, molds, steel molds, etc. It can cut high-precision straight lines, curves, and complex geometric shapes on these materials with an accuracy of up to micrometers. Due to its principle of electric discharge, theoretically any conductive material can be processed through wire cutting technology, as long as the material can withstand local thermal effects during the processing without adverse reactions.

WORKING PRINCIPLE, ADVANTAGES AND APPLICATIONS

1. What is Wire Cutting Processing?

Wire Cut Electrical Discharge Machining (WEDM), also known as Wire Cut Electrical Discharge Machining, is a special machining technology that mainly utilizes the principle of electrical discharge to perform non-contact precision machining on conductive materials.

2. Its working principle is as follows:

1. Electrode Wire and Workpiece:

Wire cutting machining uses a continuously moving thin metal wire (usually molybdenum wire, copper wire, or specific alloy wire) as the electrode, which moves back and forth continuously during the machining process. The workpiece is fixed and connected to the positive pole of the pulse power supply, with the electrode wire connected to the negative pol
 

2. Electric Spark Discharge

When the distance between the electrode wire and the workpiece is reduced to a certain extent (usually a few micrometers), the high-frequency pulse voltage applied between the two poles will generate electric spark discharge in the small gap between them. This discharge can cause an instantaneous high temperature (up to 8000 to 12000 degrees) in a localized area, causing the metal to melt or vaporize locally.

COMMON PROBLEMS WITH WIRE CUTTING

  • Q What are the two main types of wire cutting?

    A
    Slow Wire EDM (SWEDM): Using pure water as the working fluid, molybdenum wire has a slower speed and is generally used for high-precision and high-quality machining requirements.
    Rapid Wire EDM (RWEDM): Using a working fluid mixed with a coolant, molybdenum wire has a fast speed and is suitable for mass production with low cost.

  • Q What are the characteristics of wire cutting machine tools?

    A
    Non contact machining: Due to the lack of direct physical contact during the machining process, no cutting force is generated, making wire cutting very suitable for machining hard materials or thin-walled, slender, and easily deformed parts.
    High precision machining: Wire cutting can achieve very high machining accuracy and surface smoothness.
    Wide applicability: It can process various conductive materials, including materials with extremely high hardness, such as quenched steel, hard alloys, etc.
    High degree of automation: Modern wire cutting machines are usually equipped with CNC systems, which can achieve automatic programming and control, improving machining efficiency and accuracy.

  • Q How accurate is EDM wire cutting?

    A
    A. Slow-feeding wire-cutting machine (low-speed wire-feeding EDM wire-cutting machine):
    Cutting accuracy can usually reach 0.001mm level (i.e. 1μm).
    The surface roughness can reach Ra0.8μm and above.
     
    B. Fast-track wire-cutting machine (reciprocating wire EDM):
    The machining accuracy usually reaches 20μm.
    The surface roughness can reach 3.2μm.

  • Q In order to improve the precision of EDM wire cutting processing can take those measures?

    A
    Control the temperature and use a water temperature cooling device to reduce the thermal deformation of the machine tool.
    Adopting linear motors to improve the control accuracy of precision positioning.
    Use special materials such as ceramics and polymer artificial granite to make machine tool components, in order to reduce the impact of temperature changes on cutting accuracy.
    Adopting a fixed workbench and column moving structure to improve the load-bearing capacity of the workbench.
    Adopting immersion processing to reduce thermal deformation of the workpiece.
    Adopting motor servo and closed-loop electrode wire tension control to improve tool alignment accuracy.
