High precision fast wire cutting machine

Types of high precision fast wire cutting machines

An innovative technique for cutting is using a WEDM machine, also known as a wire-cut EDM machine or wire electrical discharge machining. This machine uses a thin wire as an electrode to cut metal workpieces precisely. It works by passing an electric current through the wire, creating an electrical discharge that erodes the material of the workpiece. A high-precision fast wire cutting machine offers several benefits, including the ability to cut complex shapes with high accuracy and tight tolerances, smooth cutting surfaces, minimal material distortion, and the capacity to cut a wide range of materials, including hardened steel and other metal alloys.

Generally speaking, the high-precision fast wire cutting machines can be classified according to the type of wire used, the feeding methods, their control systems, and some other aspects.

• By the type of wire: As mentioned above, the wires used for high-precision wire-cutting machines are various, including brass wire, fine gold wire, and coated wire. Brass wire is the most common type used in general industry. Some high-end machines may use fine gold wires with better conductivity and lower resistance. Alternatively, some devices may use coated wires, such as those with a PVC coating, to achieve specific cutting purposes or improve cutting quality.
• By feeding methods: A high-precision wire-cutting machine is usually equipped with a wire feeder that can change the feeding method. This machine can be manually fed or automatically fed. Manual feeding means the operator manually places the material to be cut into the machine. On the contrary, automatic feeding means the machine automatically feeds the material through a system or device. Automatic feeding is more efficient and suitable for mass production.
• By control systems: High-precision fast wire-cutting machines usually have different control systems that allow precise control and programming of the cutting process. Some common control systems are industrial computers, CNC (computer numerical control) systems, and PLC (programmable logic controller) systems). These control systems allow users to easily input and change the cutting parameters and ensure accurate and repeatable cutting results.
• By cutting methods: Electric discharge machining wire cutting uses different techniques according to the shape and size of the objects. For example, the rotary cutting method suits round and cylindrical objects, while the contour cutting method is for intricate and complex-shaped workpieces.
