WPG 7 – Compact External Cylindrical Grinding Machine for Workpieces up to a Length of 250 mm
Highly productive, flexible, and with an extremely small footprint – the new WPG 7 CNC external cylindrical grinding machine provides boosted performance in the machining of small and medium-sized workpieces.
The Solution for Perfect Grinding Processes
With the WPG 7 from EMAG Weiss, the machining of workpieces up to a length of 250 mm and a maximum diameter of 200 mm is efficient every step of the way.
This is thanks to a rigid machine concept, very dynamic axes, a powerful grinding wheel drive, and a very small footprint. All in all, the WPG 7 only needs around four square meters' space. The robust machine is also highly accessible and can quickly be re-tooled for changing machining tasks.
High-end CNC control
At CNC-Technik Weiss GmbH, we have always put our trust in the expertise of Eckelmann AG for our CNC control solutions.
Even before 1980, Eckelmann started to develop a CNC control specifically for cylindrical grinding. Today, these control units offer functions tailored specifically for grinding, and are still far ahead of the products of other controller manufacturers. Currently, we use the Eckelmann ENC66 controller in all CNC machines.
