EDFH-1

EDM Hole Drilling

The EDFH-1 is built with reliable long-term mechanical precision in mind
The EDFH-1 machine expands on the advanced ultra-precision capability of the EDAC-1 by incorporating high-accuracy EDM Drilling into the same machine platform. The EDFH-1 can perform high accuracy standard sinker EDM processing and achieve surface finishes down to 1.3µin Ra (0.25µmRz). The machine’s refined generator can produce inside corner radii as small as 5 microns (0.0002”), and the Z-axis jump speed of 10m/min (394 ipm) provides efficient high-speed machining while maintaining a ±1 micron depth control capability using a core-cooled ball screw. The included high-speed C-axis provides rotation speeds up to 2,000 rpm, and the programmable W-axis provides rigid alignment for EDM drilling die guides and also features a middle guide arm to support and prevent vibration of small diameter electrodes with flushing pressures up to 10 Mpa (1,450 psi).

Technical Specifications

The EDFH-1 is built with reliable long-term mechanical precision in mind, as the machine construction includes alignment tolerances of 2 microns (0.00008”) or smaller over the full stroke of each axis.  The design of the EDFH-1 includes many elements to enhance thermal stability, such as isolating the heat from the electrical/generator cabinet from the machine structure and integrating the di-electric reservoir into the base casting, which also minimizes the machine’s footprint.  The EDFH-1 utilizes a stationary work table design to further elevate precision, and excellent work tank access and operational ergonomics are provided by the programmable 3-Sided rise and fall work tank system.
 
Makino’s revolutionary Hyper-i control harnesses all of the advanced capabilities of the EDFH-1 into an efficient and user-friendly interface.  The intuitive and streamlined layout of the Hyper-i control addresses the operator's needs and includes practical and useful tools that empower advanced operations, such as the E-Tech Doctor function.  A large high-definition 24” class touch screen provides a commanding view over machine operation and supports easy customization and remote monitoring options for operator preferences. The Hyper-i control also includes on-board machine manuals with integrated training videos, delivering a new level of operating efficiency to the shop floor with a focus on optimal machine performance.
