Molybdenum wire automatic tension system
1. Basic accessories of controller BMW-5000 model with New High frequency Power supply. 
2. Double Direction Servo wire tension system
3. With BMXP software, which run base on Window XP, can use Autocad directly
4. EMERSON inverter (U. S. A)
5. Linear Guide way from PMI
6. LCD monitor
7. Industrial computer
8. Central lubricate system
9. CE certificate from England. 
1. The casting for the main machine bed, using high rigid HT250, which made by a famous Japanese manufacturer. Integrated structure design, all casting parts are made with the procedure of resin-send and twice heat treatment to improve the max load weight and keep a good precision for long time and avoid the distortion. 
2. The controller equipped the 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. 
3. 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
4. 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
5. Embedded Control system can be connected with many design software smoothly. 
6. 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. 
7. The control parameters of pulse power is directly by the software, in order to not only improve anti-jamming capability in pulse power output, but also increase the roughness of work piece. 

8. Variety of pulse power can be chosen, which is suited for a number of processing conditions to improve the cutting ability of the high precision parts. 
9. With a large database storage capacity, 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
10. Three layer filters can prolong the using life of the working solution and improve the finishing, with BAOMA series working solution can achieve a better performance and PRO-environment. 
11. Can be equipped with the close-loop control system, use the MITSUBISHI, YASKAWA servo control system and servo motors. 
12. The wire moving is controlled by EMERSON transducer, which adopts unlimited adjustment. 
13. The processing components involve godet mechanism, the best roughness Ra≤ 1.5μ M (the finishing can be improved greatly by using the BM working solution)
14. Customrized extra-big machine can be manufactured in our company.
