Wittmann Battenfeld, Torrington, Conn., has added another new model to its W82x Series of linear servo robots. The chief difference in the W822 is a rack-and-pinion drive for the vertical axis. It allows the robot to handle 15 kg payloads on strokes of 1000 or 1200 mm and 12 kg with the 1400-mm option. In many other respects it is comparable to the W821 model. It can have a horizontal axis of up to 4000 mm. It was developed in response to demand for greater payload and versatility on small to mid-sized molding machines.
