8-series Robots

Innovative 8-series Robots, manufactured by Wittmann Battenfeld India Pvt. Ltd., have state-of-the-art compact servo modules integrated on the robot itself thus eliminating the need for an external control cabinet. The integrated control cabinet is mounted behind the horizontal axis to save space in the moulding shop. All sensors and actuators on the robot are directly wired to an intelligent control card under the robot hood. The connection to the control cabinet and the teach pendant is through a simple bus cable.
All 3 main axes are equipped with servo drives. Larger robots, including model W721, are driven in the Z-axis by a rack and pinion arrangement with built-in lubrication chamber for high-speed operation and long life. The rack and pinion drive also guarantees precise positioning for long strokes, avoiding stretching of long belts. The use of standard and well-proven components guarantees maximum load rating and easy availability of spares when necessary. As a standard, the robots are equipped with linear bearings with lubrication chains for reduced maintenance.
Large aluminium extrusion provides a stiff, vibration-free foundation for the vertical arm. The reduced moveable mass allows high acceleration and deceleration for extremely short cycle times. The bearings for horizontal stroke and kick stroke are positioned in the main carriage next to each other for optimum stiffness and minimum vibration during high-speed operation, allowing precise insertion and removal.
