WPG 7 from EMAG WEISS: High-precision external cylindrical grinding with a minimal footprint

External cylindrical grinding at the highest level and on the smallest footprint: The WPG 7 from EMAG WEISS ensures perfect cylindrical grinding in many applications. High-tech components guarantee precision in the µm range.

For small shafts, pinions and much more

For example, do you want to cylindrically grind small shafts or pinions (up to a workpiece length of 250 mm) at one-second intervals - and with a machine that takes up less space? Here is the perfect solution: The WPG 7 external cylindrical grinding machine from EMAG WEISS scores points with a very powerful grinding wheel drive, a large grinding wheel, simple operation based on a Fanuc control system and optional automation.

Six Reasons for Ordering this Machine

Flat design of the grinding head of WPG 7
High rigidity due to low/flat design of the grinding head.

1. Precision and Process Reliability

The machine’s ridged design ensures exceptional component quality by eliminating disruptive vibrations and optimally transferring heat. Options also include high-precision, in-process measurement; passive longitudinal positioning; an automatic balancing system as well as GAP and crash control.


WPG 7 as 0° straight or 30° angled stitching machine
Variable configuration: Available as a 0° straight or 30° angled stitching machine, workpiece headstock with stationary and moving point MK4.

2. With Speed

The WPG 7 external cylindrical grinding machine is available in two versions for straight grinding or angular plunge grinding (30 degrees). In both cases, the powerful grinding wheel drive with up to 50 m/s and the large diameter of the grinding wheel (CBN or corundum) of up to 500 millimetres score points. Both ensure enormous speed.

Very short workpiece changeover times thanks to integrated loader and short distances.

3. Automated

EMAG WEISS offers the cylindrical grinding machine with automation as well as manual loading. Many automated systems such as chain conveyors, pallet circulation or robots can be implemented, using a separate linear gantry including gripper for this purpose. It is virtually integrated into the enclosure and linked-up with the conveyor belt and the like. The changeover times are minimal.

5. All in One

Are you using oversized universal cylindrical grinding machines for machining smaller components? That is often uneconomical! In contrast, the WPG 7 is extremely compact. Everything needed is located within just under four square meters - from the electrical cabinet to the lubrication and cooling system.

Transportation is quick and easy.

6. Ready in no time at all

The hook machine fits on two Euro pallets, making it very easy to transport to the site. Our experts simply connect the power and compressed air. That's it! This process usually takes less than four hours. No major adjustments or new settings are necessary.
