Suzhou Excellence Intelligent Technology Co., LTD, established in 2013 with a factory spanning 3,000-5,000 square meters and an annual export value of US$5-10 million, is proud to present our advanced 7 Axis CNC EDM Drilling Machine. Designed for precision and reliability, this machine operates on a 220V 3-phase 50Hz power supply and features submerged machining technology. With an ultra-fine feed rate of 0.02mm/min, it delivers exceptional accuracy for the most demanding drilling applications. Our ISO9001 certification ensures consistent quality, making this machine a trusted choice for clients across North America, South America, Europe, Asia, Africa, and Oceania.
This machine is engineered for high-precision EDM drilling, capable of creating micro-holes and deep holes in conductive materials like hardened steel, tungsten carbide, and superalloys. The 7-axis CNC system allows for complex angled drilling and multi-position operations without repositioning the workpiece, significantly increasing productivity and flexibility.
Key Features & Benefits
- 7-Axis CNC Control: Provides unparalleled freedom for drilling at various angles and positions, reducing setup time and improving part accuracy.
- Submerged Machining: The entire drilling process occurs under dielectric fluid, ensuring stable spark discharge, efficient debris removal, and superior surface finish.
- Ultra-Low Feed Rate (0.02mm/min): Enables precise depth control and minimizes electrode wear, ideal for micro-drilling and thin-wall applications.
- 220V 3-Phase 50Hz Power: Compatible with standard industrial power grids in many countries, offering reliable operation with stable energy consumption.
- Advanced CNC System: User-friendly interface with pre-set drilling cycles for common patterns, automatic electrode alignment, and real-time monitoring.
- High Rigidity Structure: Cast-iron base and reinforced columns minimize vibration, ensuring long-term stability and repeatability.
- Automatic Electrode Changer (Optional): Available upon request for high-volume production, reducing manual intervention.

Frequently Asked Questions
-
Q: What materials can this machine drill?
A: It is suitable for any conductive material, including hardened steels, stainless steel, titanium, tungsten carbide, copper, and aluminum alloys. The submerged process ensures excellent performance even with difficult-to-machine alloys. -
Q: What is the minimum hole diameter achievable?
A: With standard electrodes, the minimum diameter is 0.3 mm. With specialized micro-electrodes, holes as small as 0.1 mm can be drilled (customizable setup required). -
Q: Can the machine drill at non-perpendicular angles?
A: Yes, thanks to the 7-axis design, it can drill at any compound angle within the range of the A, B, and C axes. Programming is done via the CNC controller. -
Q: How does submerged machining improve hole quality?
A: Submerging the workpiece and electrode in dielectric fluid provides continuous flushing, removes debris instantly, and maintains a stable spark gap. This results in straighter holes, finer surface finish, and reduced heat-affected zones. -
Q: What is the power consumption of this machine?
A: Typical power consumption is around 8-12 kVA depending on machining parameters. A stable 220V 3-phase supply is required. -
Q: Is training provided for operators?
A: Yes, we offer on-site training at our facility or via video instructions. Our support team is available to assist with programming and troubleshooting. -
Q: What is the warranty period?
A: The standard warranty is one year against manufacturing defects. Extended warranty options are available upon request. -
Q: Can I get a customized electrode holder or fixture?
A: Absolutely. We provide customization services for special electrode geometries and workholding solutions to meet your unique part requirements.
