![]() | 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.)

Machine Body
The Taper Cutting Mechanism: It's driven by Srstep-motors to realize U and V movement, which can make the 4 axis (X,Y,U,V) simultaneously movement.
Structure of wire frame:The symmetric structure for the upper and down frame to keep the tension of moly wire within the scope of normal tension. There are same quantity of arrange wire pulley, which make same tension in every point of the moly wire. So no matter thin or thick work piece, the moly wire is not easy to break down. Comparing with "C" Shape structure, which always been used in other factories' machine. Our structure short the wire travel route to avoid the shock during the running of the wire and make sure the accuracy.
The working table: The working table with T-shape slots, we supply a standard clamp for free.
The wire winding and traveling system: Wire winding drum is made of special steel, which is more stable, anti-corrosion. Emerson (U.S.A) converter control the running direction, Which can be used longer time, improve the precision, roughness and reduce the wire broken.
The Machine Body: Adopt the base of Meehanite cast iron (HT250), the cast of "Baoma" machine is made by the resin-sand technology with the influence of high temperature annealing, which makes the machine body of high load intensity and has ability to resist distortion. And the max loading of the working table is better than other Chinese machines.
Guideway and Ball Screw: Adopt Steel Linear guideway and precious ball screw from Taiwan.

1.Upgraded the High Frequency System
Exclusive non-resistances &Non- Electrolysis High Frequency power supply, single cutting speed up to 12,000 square per hour,3 times cutting, the best roughness can be up to Ra0.6μm.Non- Electrolysis power processing alloy does not change color. non-resistances High frequency also saves 60% power, only 0.4KW/H.
2. Lower Moly-wire consumption
While focusing on research and development to improve efficiency, greatly reduce molybdenum wire wearing, cutting efficiency increased by 30%, molybdenum wire wearing is lower ( 200K MM2/0.01mm wire weared)
3. Low failure rate, long using life
New electrical cabinet design, non- resistors, low heat, longer using life of electronic components; No fan, reduce cutting water mist into the electrical cabinet.
4.New CoolCut software, friendly man-machine interface
The latest research and development of Coolcut control software, based on Windows10 64-bit platform, Ethernet interface, high communication rate and better stability. Servo motor supports up to 50,000 steps. Support pitch compensation and AR rotation.
5. The core technology is easy to operate
CoolCut WEDM control system software is a Windows/ Linux-based CNC wire-cutting control system independently developed by BAOMA CNC. The system runs on Windows XP, WIN7, WIN10, WIN11 and other common operating systems. It is based on Ethernet communication and does not need to insert a card with PCI slot. Avoid the problem of poor contact that often occurs with the plug-in. No driver installation, simple, convenient and stable
6. X,Y,U,V Simultaneous cutting can cut Taper, Top-Bottom different shape jobs.
Erosion is performed with separate upper (UV) and lower (XY) profiles, which may include real-time synchronization anywhere during rough cutting, joint management, and optional finishing.
Outline cutting is the most flexible and commonly used machining, capable of straight cutting and taper cutting, and cutting workpieces with vertical and back angles. BMA uses advanced taper variations and corner types (cones, cylinders and programmed radii) to cut geometries. 4-axis profile cutting uses two synchronized profiles: UV (upper) profile and XY (lower) profile. Matching points provide control over the precise geometry and surfaces produced during the machining process
7. Agility and free-adjusting for Z axis
During cutting, the temporary move Z axis lift is used to take the workpiece, which can automatically return to the original processing point after taking.
8. Rotate A axis cutting.
A rotating axis -R axis is added during cutting, thus machining multi-sided workpieces through one setting. The machine can perform both linear and rotational motion at the same time, so the rotation axis increases the variety of shapes that can be cut.
9. With mechanical origin, pitch compensation, several years later, when the wear accuracy of the bed is not up to standard, the laser interferometer can be used to correct the machine accuracy
10.Multi-user coordinate system
The current cutting coordinates can be remembered for users to prioritize emergency cutting. Processing records can be queried, including all records in the execution cutting, zero clearing function, Split center function and go back to original.
11.Brass wire cut machine AR aligment
