This type is popular machines.Machines are with Stepper motors , Max. taper angle 90 degree, Affordable prices.
The Machine Body: Adopt the base of Meehanite cast iron (HT250), two aging treatment to eliminate stress and effectively inhibit the deformation of the machine tool.which makes the machine body of high load intensity and has ability to resist distortion.
Guideway and Ball Screw: Adopt Steel Linear guideway and precious ball screw .
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. So no matter thin or thick work piece, the moly wire is not easy to break down.
The wire winding and traveling system: Wire winding drum is made of special steel, which is more stable, anti-corrosion. converter control the running direction, Which can be used longer time, improve the precision, roughness and reduce the wire broken.
The Taper Cutting Mechanism: It's driven by two step-motors to realize U and V movement, which can make the 4 axis (X,Y,U,V) simultaneously movement.
The working table: The table is equipped with a movable modular clamping device that can be moved to multiple positions to achieve installation and clamping according to the actual situation of the workpiece.
Working area:The frame water retaining structure with a three-sided opening design can against splashing and dripping of cutting fluid,allows for unobstructed operation and loading/unloading of workpieces.
Control system
Adopt the digital high frequency power, the power generator is controlled by Controlled by the control panel, which can improve the precision and the stability of the pulse signal and reduce the probability of the high frequency power failure, advance the machining efficiency and the quality of working piece. Max. Current 10A ,max efficiency≥300m²/min（Determined by material and thickness）, surface roughness≤2.5~3.2um. The modular design is used in the internal wiring, which can reduce the probability of the failure, and it's easy to maintain.
Autocut software basic function
Ø Autocut software is the unique software for WEDM running on the condition of windows XP.It can be smoothly connected with many design software such as AUTOCAD & etc.
Ø Built-in programming graphics and automatically prepared machining code programs.
Ø The multi-CPU function enables simultaneous processing and programming.
Ø Parallel compensation, clear angle setting, program image, corner optimization, scaling and other functions opened.
Ø Exchange X and Y axis randomly to adapt different machining state. Set wire controller's move speed freely.
Ø Record machining tracking information, to monitor machining during unmanned operation to ensure safety.
Ø Coordinate system: absolute coordinate, incremental coordinate (relative coordinate).
Ø Functions of coordinate transforming, zoom in and zoom out, rotating and tracking display in real time
Ø Functions of interpolation of straight line and circular arc.
Ø Function of taper processing
Ø Function of processing different top and bottom shape
Ø Functions of short circuit and wire-break handling
