Wire EDM machines

Wire EDM Machines, also referred to as Electrical Discharge Machining or Spark Machining, are utilized in metal fabrication to achieve precise shaping of conductive materials through the use of electrical discharges or sparks.

Spark erosion technology, implemented in Wire EDM Machines, provides efficient solutions for overcoming difficulties encountered in conventional machining, especially in tasks involving small angles and taper cutting. Its widespread implementation across industries such as automotive, mold and tool manufacturing, and aerospace highlights its crucial role in achieving precise cutting results.

The Wire EDM Machines, use a metallic wire (usually a molybdenum wire) to cut a programmed shape in a workpiece. The material is removed from the workpiece by a series of rapidly recurring sparks between the wire and the metal piece, separated by a dielectric liquid. The wire operates without any physical contact with the metal surface, eliminating thus any mechanical action on the workpiece. This remarkable attribute is one of the key advantages of Wire EDM Machines. With this non-contact cutting method, the properties of the metal surface remain unchanged, free from any deformations or microcracks.

The dielectric liquid effectively eliminates the debris from the machining area and undergoes filtration before reentering the system. FinMach BQ Wire EDM Machines incorporate a dedicated double filtration system, ensuring the dielectric fluid maintains exceptional cleanliness. This significantly enhances cutting efficiency and maximizes machine performance to the highest degree.

To safeguard against erosion and potential wire breakage, the molybdenum wire undergoes a continuous winding and unwinding process, ensuring constant movement of the active section. FinMach BQY Wire EDM Machines feature an advanced Wire Tensioning System, ensuring precise machining and impeccable surface finishing.

Wire cut EDM machines demonstrate exceptional versatility in effortlessly handling a wide range of challenging materials, including hard, brittle, and difficult-to-machine substances such as high-alloy and hardened steel.

FinMach BQ Wire EDM Machines, precision-engineered CNC machines, are designed to process all the conductive materials, including Iron, Carbide, Tool steel, Stainless steel, Titanium, Inconel, Hastelloy, Stellite, Copper, Aluminum, and more, these machines exhibit exceptional cost-effectiveness, low power consumption, and deliver superior accuracy and efficiency in the machining process.

FinMach BQ Wire EDM machines boast exceptionally low hourly operating costs, typically ranging from 1 to 2 EUR/hour. This represents a remarkable cost reduction of 15 to 20 times compared to Wire EDM cutting processes utilizing brass or stratified copper wire.

FinMach BQ series Wire EDM Machines are built with premium mechanical, electrical, and electronic components. The machine body is made from high-strength grey cast iron (EN-GJL-300) using resin sand technology. It undergoes double high-temperature heat treatment and at least 8 months of natural aging to prevent deformations. These measures guarantee outstanding performance in cutting accuracy, speed, reliability, and user-friendly operation.
