High Precision: The wire cutting machine allows for highly precise cuts, capable of ±0.01mm accuracy and surface roughness of Rα 1.25-2.5um.
Flexible Shapes: Ideal for intricate and small-sized parts, particularly irregular shapes or sharp corners.
Minimal Heat Effect: The heat generated is localized, suitable for heat-sensitive materials, maintaining dimensional stability.
No Macroscopic Cutting Force: Non-contact processing avoids part deformation, making it suitable for low-stiffness workpieces with high surface finish.
High Material Utilization: The narrow cut width means minimal material waste, though the cost is higher, making it less suitable for mass production.
Automated Control: Wire cutting machine utilizes easily adjustable electric parameters and a CNC system for automated control.
Components of Wire Cutting Machine
CNC Tools
The CNC tools control the entire operation of the Wire EDM machining process. Controlling the entire operations include being in control of the sequencing of the wire path and being able to manage the cutting process automatically.
Power Supply
The power supply unit is the component that delivers pulses (from 100V to 300V) to the wire electrode and the workpiece. Furthermore, it controls the frequency and strength of the electrical charges that pass through the wire electrode to interact with the workpiece.
It is necessary to use a highly developed power supply unit to deliver the necessary quality and type of charges during Wire EDM machining.
Wire
The wire serves as the electrode to create the electrical discharge. The shape and thickness of the workpiece directly influence the wire's diameter. Typically, one can use wires with diameters ranging from 0.05 to 0.25mm. The main types of wires used include
Brass Wires
Brass is the most common EDM wire material because of its excellent conductive properties. It is an alloy of copper and zinc, and the higher the zinc content, the faster the wire cuts. However, there should be a balance because when the zinc content is over 40%, this decreases the corrosion rate of the brass wire.
Zinc coated Wires
As the name implies, you obtain it by applying a coating of pure zinc or zinc oxide on the wire surface. Manufacturers use zinc-coated wires because it improves the machining speed.
Diffusion-annealed Wires
The diffusion annealing process helps to create wires with higher zinc content (more than 40% zinc). It involves coating wires with layers of pure zinc. These wires are ideal for mass production and can machine many materials.
Dielectric Medium
The wire-cut EDM process must be carried out in a tank filled with dielectric fluid. This liquid prevents the tiny particles from the workpiece from getting attached to the wire electrode. The most common medium is deionized water which cools the process and gives the workpiece a good surface finish.
Electrodes
The electrodes in the machine are the wire (cathode) and the workpiece (anode). The servo motor controls the wire electrode, ensuring it does not come in contact with the workpiece at any point during the wire EDM cutting process.
Threading the Wire:
A thin wire made from materials like brass or coated copper is threaded through the machine and positioned close to the workpiece.
Setting the Path:
The wire is programmed to follow a specific path controlled by a CNC (Computer Numerical Control) system, which allows for the creation of complex and precise geometries.
Initiating the Spark:
Electrical discharges occur between the wire and the workpiece. The high voltage applied causes sparks that precisely melt and vaporize the material along the wire's path.
Material Removal:
As the wire moves through the workpiece, it continuously erodes the metal, creating the desired shape with high precision. The eroded metal particles are washed away by a stream of dielectric fluid, ensuring a clean cut.
Cooling and Flushing:
The dielectric fluid not only cleans the cutting area but also cools the wire and the workpiece, preventing excessive heat buildup that could alter the material properties or dimensional accuracy.
Carbon Tool Steel: Grades T7, T8, T10A, T12A. Features high hardness after quenching, but needs heat treatment to eliminate internal stress before wire cutting.
Alloy Tool Steel: Grades Cr12, Cr12MoV, Cr4W2MoV. Known for high hardenability and wear resistance, used in complex molds.
Quality Carbon Structural Steel: Grades 20, 45. Suitable for making plastic molds, but with moderate wire-cutting performance.
Cemented Carbide: YG and YT series. High hardness and stability, used for complex molds and tools but slow cutting speed.
Aluminum: Lightweight and strong, good wire-cutting performance but with moderate surface roughness.
