AutoCUT provide complete integrated solution for machining of CNC wire cut EDM. The  system includes AutoCUT control software runs at the platform of Windows, PCI based drive card installed on motherboard, high stable main board of stepper motor drive or servo motor drive, and 0.5 microseconds medium speed wire cut EDM HF power board. AutoCUT software has a plug that can be installed in AutoCAD to design cutting path and generate cutting programing directly in AutoCAD, the design makes programing more convenient and easier to learn.

AutoCUT's main features:
1. It supports graphics-driven automatic programming, customers do not need to touch the code, just the graphics settings cutting technology can be cut, at the same time, it supports by other wire cutting EDM software created by the list of 3B or G code, and only need to read and process can be cut.
2. The software is embedded in AutoCAD, CAXA and some other software, and the customer only needs to know AutoCAD or other design software, is easy to use and does not require special drawing training.
3. Several machining modes are combined for cutting (continuous, single, forward, backward, back, etc.).
4. The XYUV four-axis direction is adjustable, the drive motor can be set to 5-phase 10 beats or 3-phase 5 beats, and so on.
5. Real-time monitoring of X, Y, U.V. and cutting.
6. Machining preview, real-time display of the cutting process; taper processing 3D display and tracking, zoom in and out to view graphics, front view, right view, top view, etc.
7. The ability to cut multiple times, as well as the customer-maintained database of cutting parameters, make multiple cuts easier and more reliable.
8. Belt cutting using four-axis synchronization technology, can be processed up and down different shapes of cutting convenience.
9. The control plate drives the four-axis motion, the work is stable and reliable.
10. Support sandal-on-the-card work, several electric spark wire cutters can only be controlled by one computer and cut at the same time.
11. With automatic alarm function, you can alarm in the event of cutting complete or failure, you can set the alarm time.
12. Support angle removal delay, track cutting delay, so as not to cause the impact of wire deviation.
13. Support screw pitch compensation to improve mechanical accuracy.
14. The linear scale and closed scale are supported by the servo motor to improve the positioning accuracy of the machine.
15. Support s3 different cutting methods: ordinary high-speed wire cutting EDM processing, medium-speed wire cutting EDM coding output mode and output mode.
16. Power-off memory function, restore power after cutting off the data backup, in the event of a short circuit re-tracking and troubleshooting.
17. Automatic power off after processing is complete.
 
Key functions of the AutoCUT system
1. The use of graphics-driven technology, reduce labor, improve work efficiency, reduce the error caused by workers.
2. Open to various versions of Windows XP, the software is easy to learn and use.
3. Directly embedded in AutoCAD, CAXA and other CAD software for a smooth combination of CAC/CAM to extend the cutting range.
4. Taper cutting, four-axis synchronization technology 3D design and cutting trajectory, compensation wire diameter, electrode wire diameter and large tap cutting.
5. Support multiple control cards to work at the same time. Many CNC wire cutting EDM machines can be controlled with just one computer, which has many AutoCUt PCI cards.
6. It has a database of cutting parameters, which the operator can edit, and the operator can save, edit, and read cutting parameters according to different materials, different thicknesses and required cutting properties.
7. AutoCUT optimizes the processing of ultra-thick workpieces (up to 1000mm) cutting, making the track stable and reliable.
