Wire EDM Machining Service
Wire EDM is an electrical discharge heat production process that uses deionized water and wire to cut solid metal parts.
Wire cutters discharge between the wire and the workpiece – continuous cutting with the heat generated by an electric spark.
electric spark cutting that can move along complex contours or tapered parts, Tirapid provides you with the best cutting solution
Advantages Of Electric Spark Cutting
When hardened tool steels and special materials are not suitable for cutting in ordinary ways, Tirapid will provide you with the best solution.

There are two main wires for EDM machines, brass wire, and coated wire.
Wire diameters for Wire EDM range from 0.1mm to 0.33mm, with 0.010” 0.25mm being common. The cut will spark up to 180 degrees forward, so the kerf width will be wider. Actually, width depends on what is supplied, but usually about one-third larger than the wire diameter. A 0.10″ wire cuts a path about 0.13″ wide.
The wire cutting EDM is controlled by CNC, and the wire is controlled on the 3D axis, which is more flexible. Traditional EDM cannot produce more complex, narrower angled parts, but line EDM can be performed. Parts with complex pattern angles can be cut more accurately.
The working principle is to use the continuously moving thin metal wire to perform pulse spark discharge on the workpiece to remove metal and cut it into shape.
Wire EDM is a special manufacturing process. It is different from traditional processing technology, which requires mechanical force and mechanical energy to cut, and mainly uses electrical energy to process materials. Wire EDM can process metal material with strength and hardness also tricky and complex parts.
Wire EDM’s wire runs through the entire workpiece, resulting in a perfect finish on the part. Often customers are amazed when they see the fine finish of a single cut. With abrasive water jets and lasers, the larger the part, the rougher the finish.
