Wire EDM with linear motors and AWT, AL-Series, ACCUTEX

DELIVERY IN 3 MONTHS! TESTWORKS POSSIBLE!

PURPOSE:
The machines are equipped with cylindrical linear motors and high resolution optical rulers of 0.1µm with closed loop control to the motors drivers. Smooth motion on all axes, low friction rate and closed loop control makes possible continuous cutting with highest repeatability, roughness and accuracy on the workpiece. Quick servo motion allows to increase the spark gap control sensitivity and as a result the cutting efficiency by 8-10% comparing with similar machines.

FEATURES

ACCUTEX Machines AL-series are capable to reach a surface roughness of Ra 0.35 µm and even Ra 0.08 µm (optionally) and a machin¬ing accuracy of ±2.5 μm. In the basic version, cylindrical linear drive units and linear optical scales with 0.1 μm resolution ensure the full loop control over the machines.
The fast servo response causes a higher discharge sensitivity in the spark gap thus increasing cutting speed by 8–10% when compared with similar machines.
The machine structure has a T-shape design with a shorter Y-axis (work table) mounted on the X-axis. The broad frame prevents buckling in the extreme points during work table travel
AL series of EDM wire-cut machines are designed to perform challenging tasks such as high-precision gapless dies cutting

Features

«AC Servo Tension Wheel», wire tension control during cutting, has reverse tension when wire broken.
«Wire End Needle-Shaping», special cut-off wire features, when wire burnout the reverse tension pull wire back and needle shape of wire end forming automatically.
«Waste Wire Auto Removing Device» – exclusively designed by Accutex. Automatically remove the remains of broken wire by pressed air into the wire rubbish container.
SD-Master – the system that provides high repeatability in accuracy by applying the same cutting data on different machines. Improves the quality of the workpiece and simplifies the management procedure. The SD-Master high-speed cut with a stable feed rate stabilizes the cutting process, especially in high-speed mode.
AccuteX intelligent current generator – it can work with changing conditions of the workpiece thickness and water washing, which allows processing with high cutting speed and no problems with wire breaks.
High resolution signal processor – provides a smoother control of speed and increases the stability of position control. Can match the best contour accuracy.
Taper cutting control system – For different cutting parameters, wire diameters, angles and thicknesses of the workpieces, the Accutex controller automatically optimizes the parameters to maintain the best angular performance with high accuracy, as well as the cutting speed. Even at small and continuous angles, Accutex can still provide better accuracy.
Anticollision system – The machine has a built-in protection against mechanical collisions of the upper head with devices or workpieces.
6th axis rotary table as option – can be completely submerged in water and will still maintain high performance and accuracy, IP68 protection class. The built-in motorized spindle has an ultra-high resolution of 720,000 pulses per revolution, eliminating problems with backlash. The turntable can be used in both vertical and horizontal positions.
