Product Description

Products introduction
High temperature corrosion metal produced by discharging between electrodes and metals in EDP perforator is used to process fine holes of super- hard steel, cemented carbide, copper, aluminium and any conductive material. EDP can process 0.015mm or tapered holes at least. It is widely used in precision die processing, and is generally used as the auxiliary equipment of WEDM machine tools.

ZNC Processing matching

1. three axis digital display, control deep processing;

2. High-speed and low-speed one button operation (just select the diameter of the corresponding electrode wire)

3. connected pump, rotary head alloy seal, long service life.

Performance characteristics 
Machining aperture 0.3-3.0 mm, maximum depth-diameter ratio can reach more than 300: 1. 
Processing speed can reach 5-40 mm per minute, servo stroke 300, can use super-long electrode tube, drug-saving electrode tube 15%. Can process stainless steel, quenched steel, cemented carbide, copper, aluminum and other conductive materials
It can penetrate directly from inclined plane and surface. 
Servo lifting adopts double linear guide rail and electric lifting, which ensures the processing accuracy and speed of products. 
The spindle adopts two-speed control mode, which can double the speed of back-off and closely track the processing time, so as to realize efficient and stable processing of fine electrodes. 
Taiwan rotary head processing is stable and leak-free, equipped with high-pressure water pump
The X and Y axes of the worktable are equipped with grating digital display, and the operation is accurate.
