INTELLIGENT BMXP CONTROL SYSTEM
BMXP Intelligent software, which integrates the program and control and based on Windows Xp. This new designed BMXP software is the unique software for WEDM running on the condition of windows XP. 
Using the PCI slot controller card and the High-tech Industrial computer, which greatly enhanced the stability of control and greatly reduced the computer the failure rate. 
To achieve a fast and convenient computer communication network, through network technology, graphics, data and program transmission, can be directly controlled by the technical design department since the first establishment of a program 
Embedded Control system can be smoothly connected with many design software such as AUTOCAD & etc. 
The search function of mechanical origin enable the transmission screw pitch compensation, in order to greatly improve the positioning accuracy, especially in Servo control system.
With a large storage capacity database, which accumulated from many experiences. User can choose the suitable parameter according to deferent working conditions. Users can adjust machining parameters to establish a database at any time according to their own experience 
The parameters of pulse power is directly controlled by the software , so as to not only improve anti-jamming capability in pulse power output, but also increase the roughness of work piece and reduce the loss of molybdenum wire .
Pulse power of the control parameters directly from the software to control and improve the ability of pulsed power output of the interference, thereby increasing the roughness of workpiece, reducing the loss of molybdenum wire, you can choose a variety of pulse waveforms for a variety of processing conditions, improve the cutting ability of the workpiece.
Simplifies the operation buttons on the control panel, a large number of button functions directly controlled by software to achieve.
