Multitasking:

NC files can be edited while machining, and multiple NC files can be opened and edited at the same time.

4

Real-time information display:

During the processing, real-time status information such as total processing time, conditional processing time, remaining time of scheduled processing, processing speed, number of subprogram calls, orbital cutting etc.

5Language selection: Switch between Chinese and English
6The online help manual allows the operator to check the screen input instructions, G code instructions, discharge conditions, etc. at any time.
7With high-speed two-stage electrode lifting function, and can periodically add an ultra-high lifting on the basis of the original high-speed lifting.

12

Expert processing technology database:

Perform automatic and manual processing of combinations of electrode and workpiece materials: copper/steel, graphite 1/steel, graphite 2/steel, copper/aluminum alloy, graphite 1/aluminum alloy, graphite 2/aluminum alloy, silver tungsten/steel, copper Tungsten/steel, silver tungsten/tungsten carbide, copper tungsten/tungsten carbide, copper/zinc alloy, graphite/zinc alloy, copper/copper alloy.

13

AUTO processing function:

Input processing information such as electrode and workpiece materials, processing area, electrode undersize value, and final processing surface roughness. The system automatically calculates processing parameters based on the expert processing technology database and automatically completes the entire process from rough machining to finishing.

14

Automatic positioning function:

It has the functions of end face positioning, angle positioning, column center positioning, hole center positioning, any three-point circle center positioning, and discharge position alignment positioning.

15

Online measurement function:

The automatic positioning function can be used to measure and correct the processed workpiece online.

16

Automatic arc clearing circuit:

During the process of electrical discharge machining, the machining gap status is monitored in real time. When slight short circuit or arcing occurs, arc clearing processing and alarm are performed in a timely manner.

17
