6 Reasons to Choose the WPG 7

The WPG 7 features a flat, low-profile grinding head designed for maximum stability.
Enhanced rigidity achieved through the low-profile, flat design of the grinding head.

1. Precision and Process Reliability

The WPG 7 ensures consistent, high-quality results with its rigid design that eliminates disruptive vibrations and optimally manages heat transfer. Key precision features include:

  • High-precision in-process measurement for real-time adjustments.
  • Passive longitudinal positioning for stable workpiece placement.
  • Automatic balancing system for reduced downtime.
  • GAP and crash control to protect the machine during operation. 

     
WPG 7 available as 0° straight or 30° angled stitching machine for versatile applications.
Flexible configuration options: Available as a 0° straight or 30° angled stitching machine, featuring a workpiece headstock with stationary and moving point MK4.

2. Speed and Versatility

Choose between two configurations:

  • Straight Grinding (0°)
  • Angular Plunge Grinding (30°)

With a powerful grinding wheel drive capable of speeds up to 50m/s, and a grinding wheel diameter of up to 500 mm (CBN or corundum), the WPG 7 excels in fast, efficient operations.

WPG 7 equipped with an integrated loader and compact design for fast changeovers.
Minimized workpiece changeover times with an integrated loader and short distances.

3. Automation for Maximum Efficiency

The WPG 7 supports both manual and automated loading systems. It integrates seamlessly with:

  • Chain conveyors
  • Pallet circulation systems
  • Robot automation 

Thanks to an integrated loader and short travel distances, workpiece changeover times are minimized, keeping your production line running smoothly.
