• Stainless steel worktable with hardness HRC 50°
• Machine casting designed based on FEA analysis to increase rigidity
• Machine base with extra wide design
• Water-cooled lower arm to prevent thermal expansion; rib locations designed by FEA to ensure thermal balance and optimized rigidity

Precision and motion

• Extended distance between linear guide ways
• Cryogenic treatment of C1 class ball screw
• Ball screw supported on both ends and high-resolution AC servomotor achieving micro-step accuracy up to 1 µm
• Laser calibration and pitch error compensation
• Closed-loop linear scale (option)

• CRC functions to verify received data integrity
• ASIC chip to increase circuit stability
• Watchdog functions for system self-protection
• Real-time feedback of sparking information to stabilize spark erosion

Automatic wire threading

• Threading at break point: annealing improves wire straightness; threading at break point during machining with near 100% reliability without return to start hole
• Submerged wire threading: can be executed during submerged machining without draining/refilling the tank
• Multi-hole machining function: if rethreading fails, system skips current hole, records location and recalls it later to complete the cut
• Threading with water jet for tall workpieces; supports threading up to 500 mm thickness enabling continuous unmanned operation

Electrical and machining functions

• Electrolysis Free (EF) AC power generator for improved cutting performance
• Short-circuit solution: special discharge circuit to eliminate short circuit during threading misalignment and improve machining efficiency
• RTS (Real Time Sparking): fast feedback of ineffective discharges and automatic condition adjustment to improve cutting efficiency

Surface finish
Super Finish Circuit (option): high-frequency surface finish technology capable of achieving roughness Ra < 0.2 µm in a single cut with 4 skims on steels such as SKD-11 (example: 30 mm thickness).
