Frequently Asked Questions (FAQ)
-
Q: What materials can this machine drill?
A: It can drill any electrically conductive material, including tool steel, stainless steel, hardened alloys, carbide, titanium, and copper. Non-conductive materials like ceramics require a conductive coating and are not recommended. -
Q: What is the smallest and largest hole diameter?
A: Standard range is 0.3 mm to 3 mm. For diameters below 0.3 mm or above 3 mm, please contact us for customized electrode holders and power settings. -
Q: How deep can it drill with 0.3 mm diameter?
A: With optimized parameters, you can achieve depths up to 30 mm (ratio 100:1). For deeper holes, a larger start diameter or pecking cycle may be required. -
Q: Does the machine come with a dielectric filtration system?
A: Yes, it includes an automatic paper filter unit with a fine filtration level of 5 microns. Optional magnetic separators and chiller are available for heavy duty applications. -
Q: Can I program a series of holes automatically?
A: Absolutely. The CNC control supports multi-hole pattern programming (linear, circular, matrix). You can set X-Y coordinates, depth, retract steps, and discharge parameters for each hole. -
Q: What is the electrode wear rate?
A: Under normal conditions (copper electrode, 60A, clean dielectric), the volumetric electrode wear is less than 1%. Using graphite electrodes can further reduce wear but may increase surface roughness. -
Q: Do you provide installation and training?
A: Yes. We offer on-site installation and training for international customers (travel expenses apply). Remote online training via video call is also available at no extra charge. -
Q: What warranty comes with the machine?
A: We provide a 12-month warranty covering defects in materials and workmanship. Extended warranty plans are available upon request.
