Electrical Discharge Machining

The Electrical Discharge Machining Process, also known as a Spark Machining, is a metal fabrication process, to obtain a desired shape to any conductive material by using electrical discharges (sparks).

Spark erosion technology, implemented in Electrical Discharge Machining, provides effective solutions for overcoming difficulties encountered in conventional machining, especially in tasks involving small angles and taper cutting. Its wide-ranging applications in industries such as automotive, mold and tool manufacturing, and aerospace highlight its pivotal role in achieving exceptional precision in cutting operations.

The FinMach BQ Molybdenum EDM Machines process employs a metallic wire, typically molybdenum, to shape a workpiece. Through a series of recurring sparks in a dielectric liquid, material is efficiently eliminated without any physical contact or mechanical impact on the workpiece. This exceptional characteristic is a major advantage of Wire EDM Machines, as it preserves the integrity of the metal surface, ensuring no deformations or microcracks occur.

The dielectric liquid effectively removes the machined material from the work area, passing through filtration for reintegration into the system. FinMach BQ Electrical Discharge Machining Process incorporates a specialized dual filtration system to maintain the utmost cleanliness of the dielectric fluid. This not only improves cutting efficiency but also maximizes machine performance to an exceptional level.

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 Electrical Discharge Machining Process incorporates a state-of-the-art Wire Tensioning System to guarantee precise machining and impeccable surface finishing.

FinMach BQ Electrical Discharge Machining process exhibit remarkable versatility by effortlessly processing any hard, brittle, and difficult-to-machine materials, including high alloy and hardened steel.

FinMach BQ Electrical Discharge Machining, 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 Electrical Discharge Machining process boasts 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 machines for Electrical Discharge Machining are manufactured using top-quality mechanical, electrical, and electronic components. The machine body of FinMach BQ series 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.
