Summary

The Makino EDFH 1 is an electric discharge machine designed for high-precision EDM hole drilling and sinker EDM operations. It is engineered for micron-level alignment tolerances, featuring thermal stability enhancements and a stationary work table to maintain consistent accuracy. This machine combines drilling and standard EDM processes within a single platform and incorporates advanced control features optimized for ultra-fine surface finishes and tight geometric tolerances.

Key Capabilities

• Achieves alignment tolerances of 2 microns or smaller across all axes
• Supports both high-accuracy hole drilling and standard sinker EDM operations
• Programmable three-sided rise and fall work tank system for improved access and ergonomics
• Surface finish capability down to 1.3 µin Ra
• Inside corner radii production as small as 5 microns
• Z-axis jump speed of 10 m/min with ±1 micron depth control
• High-speed C-axis rotation up to 2,000 rpm
• Programmable W-axis with guide arm for vibration reduction during small electrode drilling
• Dielectric reservoir integrated into base casting for thermal stability
• Hyper-i control system with 24" touch screen and remote monitoring options
