What is wire cut EDM?
Wire EDM machine uses a metallic wire (electrode) to cut a programmed contour in a workpiece. Extrusion dies and blanking punches are very often machined by wire cutting. In the machining area, each discharge creates a crater in the workpiece (material removal) and an impact on the tool (wear of the tool/electrode).
What is the use of wire cut machine?
Wire cutting machines are used to cut various types of wire and flexible tubing to specific lengths. They may be computer-controlled and can be programmed to cut wire or cable to specific length.
What is wire cut operation?
In wire electrical discharge machining (WEDM), also known as wire-cut EDM and wire cutting, a thin single-strand metal wire, usually brass, is fed through the workpiece, submerged in a tank of dielectric fluid, typically deionized water.
What is wire EDM wire made of?
brass
CNC Wire EDM utilizes a fine, electrically charged metal wire usually made of brass, to cut through the work piece while submerged in a tank of deionized water. The moving wire erodes any conductive material that is within . 0005” of its path, while the deionized water cools and flushes away debris from the cut.
What is a 3 types of EDM?
Electric discharge machining can be divided into three common types, Die sinking EDM, Wire EDM and hole drilling EDM.
How fast can a wire EDM cut?
EDM units from the early 1980s might achieve cutting speeds of 3-4 square inches per hour. With changes in machine design and power supplies, speeds of 17 square inches per hour became attainable in the 1990s.
How fast is the wire EDM cutting process?
Wire EDM Beginnings In 1969, the Swiss firm Agie produced the world’s first wire EDM machine. Typically, these first machines in the early ’70s were extremely slow, cutting about 2 square inches an hour (21 mm2/min.). Their speeds went up in the early ’80s to 6 square inches an hour (64 mm2/min.).
What is the best wire EDM machine to buy?
– Use larger diameter wire. – Increase power. – Increase electrode conductivity – Better flushing. – Increase tensile strength.
What are the advantages of using wire EDM machining?

Is wire EDM a CNC?
Tight Tolerances Wire EDM uses CNC technology to control the wire’s path with unmatched precision—making it an ideal solution for the production of parts with precise dimensions and extremely high tolerances.
What is the difference between EDM and wire cut?
The wire-cut EDM machine is operated by a CNC control instrument that can control the wire on a three-dimensional axis for greater flexibility. Conventional EDM cannot produce narrower angles or more complex patterns, while wire-cut EDM can be performed. A more precise cutting process allows for more complex cuts.
What are the applications of wire EDM?
Applications of wire EDM include:
- Prototype production.
- Automotive parts.
- Aerospace parts.
- Medical devices for implantations.
- Prototypes.
- Small hole drilling.
- Blanking punches.
- Extrusion dies.
Accuracy and Tolerances Wire EDM is extremely accurate. Many machines move in increments of 40 millionths of an inch (. 00004″) (. 001 mm), some in 10 millionths of an inch (.
How Fast Is wire EDM?
Wire Types When using standard 0.010″ O brass wire you can expect a consistent, reliable wire EDM cutting speed of approximately eighteen to twenty inch}/hour.
How hot is wire EDM?
This electric spark produces intense heat with temperatures reaching 8000 to 12000 degrees Celsius, melting/vaporizing almost any conductive material.
How does wire EDM work?
Wire EDM machining works by creating an electrical discharge between the wire or the electrode and the work piece. As the spark jumps across the gap, material is then removed from the work piece and the electrode.
Can wire EDM make holes?
With more than 30 years’ experience in the industry, American Wire EDM is a trusted resource for EDM hole popping. We utilize state-of-the-art, CNC-operated EDM machinery to drill blind- or through-holes as small as 0.010” in diameter in materials as thick as 11.61”.
What is advantage of wire EDM?
Advantages of Wire EDM Creates simple or complex shapes or patterns that would be challenging to produce with conventional cutting tools. The tool and the workpiece do not make actual contact which allows for machining of delicate sections and weak materials.
How long does EDM wire last?
The machines of today are engineered to last into the 25-year and longer range. This progress in prolonging the life of the WEDM machine is part design and part education in maintenance.
What is wire EDM?
What is Wire EDM? A Guide to Wire Electrical Discharge Machining Wire electrical discharge machining (EDM) is a process of metal machining in which a tool discharges thousands of sparks to a metal workpiece.
