In its basic configuration, the new WITTMANN WX193 robot model is already designed for applications involving extremely large parts manufactured on injection molding machines with clamping forces of 4,000 tons or more. With the WX193, the new WX robot series from WITTMANN has been extended upwards by adding a completely new model.

Every version of the new WX193 shows impressive dimensions:
- X-axis: from 2,000 to 3,000 mm
- Y-axis: from 2,800 to 3,600 mm
- Z-axis: from 5,000 to 9,000 mm

Like all other WITTMANN robots, the WX193 comes with a flexible, modular design, for its main linear axes are all available in a number of different lengths to enable optimal adjustment to the individual application and/or injection molding machine.

In its standard configuration, the WX193 can handle loads of up to 150 kg. An additional pivoting servo C-axis is used in this configuration. In contrast to the conventional pneumatic pivoting axes, which are the standard equipment for many robots and enable pivoting movements of up to 90°, WITTMANN has chosen the servo variant.

This version offers a pivoting range from 0 to 180°, a torque of 250 Nm and an accuracy of 0.1°. To cope with the gigantic strokes and move high payloads torsion-free across the entire working area, the Z-axis takes the form of a thick-walled double profile made of steel with a cross-section of 700 × 400 mm. All other axes of the WX193 also consist of steel components to provide maximum rigidity. For the drive systems, WITTMANN relies on rack-and-pinion combinations (used on all horizontal axes) or a combined belt and rack-and-pinion drive (for telescopic vertical axes). Of course, additional rotary axes can be built in as optional extras (e.g. servo B-rotation around the vertical axis or servo A-rotation around the parts removal axis).

The new WX193 robot is delivered with the latest version of the integrated WITTMANN CNC9 control system and the R9 TeachBox as standard. In its functionality, the R9 is based on the R8 version, which has proved its efficiency over a long time, but with a number of further improvements in the features offered by the R9 TeachBox. The TeachBox now provides better visualization possibilities, i.e. a larger display now measuring 10.1 " with multi-touch functions. The resolution of the screen compared to R8 has been increased from 800 x 600 to 1,280 x 800 pixels. Step keys implanted in the housing facilitate positioning of the robot by means of tactile feedback. Of course, the R9 TeachBox also continues to offer the familiar programming and teach environments such as TextEditor, QuickEdit and the QuickNew Wizard. This ensures downward compatibility with existing, older program versions.
