Features
1. All-in-one design, semi-enclosed stainless steel sink and baffle.
2. The integrated control system uses the least connectors to achieve the most stable and reliable effect.
3. Precision ball screw and high-precision linear guide are used to ensure the long-term and reliable operation of the machine.
4. The X\Y axis is driven by AC servo motor, with fast axis shifting speed and high positioning accuracy.
5. Multifunctional electronic hand box, realizing a series of functions such as axis shifting, positioning, and processing control.
6. It can realize four-axis linkage control (extended B\C axis).
7. Windows interface operating system and human-computer dialogue, simple and easy to use.
8. Adopt industrial control computer, fast running speed, stable and reliable.
9. Adopt self-developed CONTRA CNC EDM punching machine software (support upgrade)
10. Flexible and diverse programming methods, support CAD direct conversion, MDI list programming, etc.
11. Support simple G code instructions.
12. The system can save the processing program and record the parameters of each hole processing process and can be traced. It can also be used for quality analysis.
13. Multiple data transmission methods: USB\LAN\RS232.
