EDM Machine

A: Electrode wear drops significantly as discharge energy decreases. Roughing parameters using graphite typically yield a volumetric wear ratio of 0.5% to 1%. Finishing parameters utilizing low-current, high-frequency pulses achieve near-zero wear (< 0.1%) when paired with copper-tungsten electrodes.

A: The digital pulse generator incorporates MOSFET-based switching circuits that restrict pulse-on time to sub-microsecond intervals. This limits thermal penetration depth, holding the recast layer thickness below 10 um and eliminating micro-cracking in high-stress components.

A: Cartridge paper filters require replacement every 150 to 200 operational hours depending on material removal volume. Deionizing resin bottles must be replaced when water conductivity exceeds 30 uS/cm to prevent electrolytic corrosion of the workpiece.

A: Yes. The CNC includes a hardware-isolated robot interface (Euromap 67 or custom discrete I/O) supporting automatic door pneumatic actuation, hydraulic clamping circuits, and workpiece datum verification via touch probe.

A: The machine requires a stable floor foundation thickness of at least 300 mm, ambient shop temperature maintained at 20 deg C +/- 1 deg C to prevent thermal growth, a compressed air supply of 0.6 MPa, and a dedicated isolated ground circuit (< 10 ohms).

A: Shipments include complete electrical schematics, PLC ladder diagrams, ballbar test certificates, laser calibration reports, and an on-site geometrical test protocol executed by a certified applications engineer during final buy-off.
