In many industrial applications, using large universal cylindrical grinding machines for smaller components often proves uneconomical, as they consume excessive floor space and their full functionality remains underutilized. Addressing this challenge, EMAG Weiss has introduced the new WPG 7 external grinding machine, designed specifically for workpieces up to 250 millimeters in length.
The WPG 7 stands out for its minimal footprint while integrating a wide range of high-tech features that enhance both flexibility and productivity. With this launch, EMAG Weiss is offering manufacturers an efficient alternative that optimizes space without compromising on precision or performance.
If the goal is to finish small and medium-sized components, a large grinding machine is often unnecessary. This is the guiding principle behind the development of the WPG 7 by EMAG Weiss. The compact external cylindrical grinding machine is designed with practicality in mind—it fits on just two Euro pallets and can be easily transported by crane, making setup simple and efficient.
Despite its small size, the WPG 7 makes no compromises on quality or process reliability. Its rigid design ensures minimal heat build-up, while an optional high-precision in-process measurement system from Marposs allows independent monitoring of machining accuracy without extending cycle time.
Dialog interface ensures productivity
Straight or angled external grinding wheels are used, which have a maximum diameter of 500 millimetres, and can of course also be profiled depending on the task. Conversely, this means that it is not possible to integrate an internal grinding wheel and there is no B-axis for swiveling the headstock. Instead, the rest of the WPG 7 is a state-of-the-art solution including highly dynamic axes, a powerful and controllable grinding wheel drive and a workhead with stationary or live center (MK4/MK5 or W20/W25). The graphical dialog interface of the control panel is also important for the productivity of the solution. 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, many users are interested in the fact that EMAG Weiss offers this solution with automatic or manual loading. Many individual linkages can also be implemented around the machine because the specialists have developed their own linear gantry for the WPG 7, which is virtually integrated into the housing. It first removes the raw parts from an approximately two-meter-long chain conveyor belt, and then feeds them into the work area from the side at high speed. Once the process is complete, the finished parts are returned to the conveyor belt via a gantry. The whole process is controlled simply by a machine panel.
Already used extensively
Under these overall conditions, the WPG 7 is an ideal solution for purely external grinding processes on smaller components with a maximum length of 250 millimetres and a maximum weight of 30 kilograms. Thanks to the existing automation solution, medium quantities can also be completed at high speed. Dynamic axes and drives ensure fast grinding processes and the intuitive dialog control ensures uncomplicated changeover processes. Current market successes show that this approach may interest many users since the machine is in frequent demand at EMAG Weiss and has a proven track record.
