In many applications it is uneconomical to use oversize universal cylindrical grinding machines for the external machining of smaller components. With the new WPG 7 CNC external grinder, Emag Weiss demonstrates another way of grinding workpieces with a maximum length of 250 mm. This very small machine requires only a minimal footprint, but at the same time features a whole range of high-tech components for flexibility and productivity.

The WPG 7 fits on two Euro pallets for easy transportation by crane as an easy to set-up machine. It is then possible to start grinding immediately without compromising on quality or process reliability as the WPG 7 has negligible heat build-up thanks to its rigid design. In addition, in-process measurement with Marposs technology, which works independently of the cycle time during the machining process, is available as an option.

The machine uses straight or angled external grinding wheels (with or without profile) featuring a maximum diameter of 500 mm. It is not possible to integrate an internal grinding wheel and there is no B-axis for swivelling the headstock.

Included in the WPG 7 are features such as highly dynamic axes, a powerful and controllable grinding wheel drive, and a work-head with stationary or live centre (MK4/MK5 or W20/W25). The graphical dialogue interface of the control panel is also important for productivity. It is based on a FANUC control system and considerably simplifies the input of technology parameters for certain cycles. The basic version of the control already includes all common grinding cycles.

Last but not least, Emag Weiss offers the WPG 7 CNC solution with automatic or manual loading.
