ZNC EDM Drilling Machine

EDM drilling machines are different from wire-cut EDM and die sinker, the electrodes are hollow copper bars. The working fluid through the hollow of copper bars and discharges with work piece, erodes the metal to achieve the purpose of perforation.

• The maximum machining current is 60A, and the maximum electrode bar diameter is 6.0mm, makes it ensure a higher processing speed.

Work Piece	Material	Hard alloy
	Height	9.0mm
	Diameter	5.0mm
	Stable Machining Current	40A
	Machining Time	10 minutes
	Machining accuracy	5.0±0.06mm

• For Machining Fine Holes

RK-D is suitable for processing ultra-deep micro-holes of various conductive materials, such as stainless steel/ hardened steel/ hard alloy/ copper/ aluminum, such as wire-cut initial holes, nozzle holes, filter holes, pores, and group holes.

• It can also be used to etch away the bit and tap broken in the work piece without damaging the original hole or thread.

Main Features 

• High Speed Drilling

Use an electrode with a diameter of 5mm to process tool steel with a diameter of 9mm, and the processing time is 9min.

• Maximum Machining Current 60A

Electrodes machining method is rotary drilling in work piece, the machining current is stable at 40A, and can be increased to 50A.

• Depth-fixing Function

-- The ratio of depth to diameter exceeds 300:1.

• It is equipped with linear guideway, has higher precision than ordinary V-groove.
