WEDM take wire (Molybdenum wire or Tungsten and Molybdenum alloy wire ) as electrode, working liquid as media, Electrical discharging happened between the electrode and the work piece by using of the high frequency impulse power and the high peak current to bring high heat and high energy to erode the work piece. The preconceived track of the wire is controlled by the moving of X-Y axis and U-Y axis which are driven by the machine. Then the work piece is processed.
"Baoma" machines featured with beautiful shape, novel structure, superior performance, and convenient operation. Meanwhile they are of good rigidity, small cutting force , big load bearing, steady movement, and safety operation. they are suit to cut the workpiece of high precision, fairly good rigidity, high toughness, especially the cold die, extrusion die, plastic mould, gear cutter hob, precision component (including big taper, same taper, unequal cone, laid abnormity and etc.)
 | Medium speed wire cut EDM is a new generation of EDM machines which are widely used in the fields of moulds, automobile parts, aeronautics and astronautics, electronic instrument, military, light industry, and household appliances. |
1. The bed is a base formed by high strength cast iron (HT250), which is the load-bearing part of the machine tool. C-type structure, T-type bed (slow-moving wire body structure), casting body are cast by resin sand casting technology (slow-moving wire castings use this technology), two high temperature annealing treatment, in the same type of machine tool weight is also large, to ensure the mechanical accuracy is constant.
2. X, Y axis adopts high precision linear guide rail and high precision ball screw, AC servo motor directly connected drive, to achieve semi-closed loop control, and has the pitch compensation function, to ensure the machine can be used for a long time with high precision and stability.
3. The use of adjustable Z-axis to achieve veneer processing, effectively prevent molybdenum wire jitter, avoid cutting surface line marks, greatly improve the precision and roughness of the machined surface. And the lifting mechanism adopts a linear guide rail, which greatly reduces the verticality error, and is convenient to lift the Z-axis at any time to take away the waste.
4.The wire moving parts adopt imported linear guide rail as moving parts, and the frequency converter is used to control, whether it is at high speed or low speed, it can ensure the smooth operation of the parts, accurate speed regulation, greatly reduce the vibration of the molybdenum wire running, and ensure the processing quality of the processing end.
5.The bidirectional independent automatic wire tightening mechanism is configured to ensure that the electrode wire is stable and the tension is constant in the work, which can effectively reduce the wire consumption and improve the cutting performance.
6.The new generation of unblocked high frequency power supply is an efficient and low consumption pulse power supply controlled by Poma CNC reciprocating wire-walking EDM wire cutting intelligent high frequency pulse power control system software (obtained national copyright), with real-time monitoring function, with Poma EDM wire cutting intelligent servo tracking control system (obtained national copyright), adaptive adjustment of high frequency energy, effectively improve processing efficiency. And greatly reduce the power consumption of the equipment - significant energy saving, due to the unimpeded design, its own heat production is very low.
7.Numerical control system adopts embedded control system to achieve seamless connection with a variety of design software [such as ATUOCAD], compatible with DWG, DXF and other formats of graphic files.
8.It has powerful network communication function to realize data transmission.
9.Equipped with Pima EDM intelligent database control system (obtained national copyright), for users to choose for different workpiece cutting needs, provide fuzzy input system, there is a system to automatically match suitable parameters, simplify the requirements of operators, especially suitable for beginners. At the same time, the system also supports DIY self-configuration of processing parameters to adapt to special requirements of processing.
10.Multi-layer filter water tank extends the service life of the working liquid, improves the cleanliness of the working liquid, enhances the slag discharge performance, and finally promotes the improvement of the finish of the processed workpiece. With the use of the latest cooling liquid of Poma - water-based working liquid, it is harmless to the operator and the environment, and meets the requirements of environmental protection.
11.Automatic timing centralized oil supply system, convenient to the main parts of the machine tool (X, Y guide rail, screw) lubrication, to ensure the service life of the machine tool, reduce the workload of manual maintenance.
12.AR tilt automatic correction function, if the workpiece reference edge is not parallel to the X or Y axis, the system can make the program turn a certain Angle through the edge touch test, so that it is parallel to the workpiece reference, thus reducing the work intensity of the operator.

| 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.
