Wire Cut EDM machines

The Wire Cut EDM Machines (Wire Electrical Discharge Machining) Process, also referred to as Spark Machining, is an electrical discharge-based metal fabrication technique used to achieve desired shapes in conductive materials through the use of electrical sparks.

Wire Cut EDM machines provide efficient solutions for overcoming difficult challenges commonly encountered in traditional machining, specifically in the realm of processing small angles and taper cutting. Widely utilized in various industries including automotive, mold and tool manufacturing, and aerospace, spark erosion technology plays a crucial role in achieving exceptional precision in cutting operations.

Machines employ a metallic wire, typically molybdenum, to precisely shape a workpiece according to programmed specifications. Through a series of rapid sparks generated between the wire and the metal piece, facilitated by a dielectric liquid, material is gradually removed. The wire operates without making physical contact with the metal surface, eliminating any mechanical impact on the workpiece. This non-contact cutting method is a notable advantage of Wire EDM Machines, preserving the integrity of the metal surface and preventing deformations or microcracks.

The dielectric liquid effectively removes the machined material from the work area and undergoes filtration for reuse. FinMach BQ Wire Cut EDM Machines are equipped with a dedicated double filtration system, guaranteeing the cleanliness of the dielectric fluid. This feature enhances cutting efficiency and maximizes machine performance to an exceptional degree.

To prevent the erosion and potential breakage of the molybdenum wire, a continuous winding and unwinding process is implemented, ensuring that the active section of the wire is constantly shifting. FinMach BQY Wire Cut EDM Machines incorporate a state-of-the-art Wire Tensioning System to guarantee precise machining and impeccable surface finishing.

Wire EDM machines demonstrate exceptional versatility by effortlessly handling a wide range of hard, brittle, and challenging-to-machine materials, including high alloy and hardened steel.

FinMach BQ Wire Cut 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 Cut EDM machines offer remarkably low hourly operating costs, typically amounting to 1 to 2 EUR/hour. This translates to a significant cost reduction of 15 to 20 times compared to Wire EDM cutting processes that use brass or stratified copper wire.

FinMach BQ series EDM Machines are manufactured using top-quality mechanical, electrical, and electronic components. The machine body of FinMach BQ series Wire Cut EDM Machines is constructed from high-strength grey cast iron (EN-GJL-300), manufactured using resin sand technology. It undergoes a rigorous process of double high-temperature heat treatment and natural aging for a minimum of 8 months to prevent any deformations over time. All above to ensure exceptional performance in cutting accuracy, cutting speed, machine reliability, and user-friendly operation.
