DDS 750 XR Grinding size: 1,0 to 20 mm 2,0 to 20 mm 5,0 to 30 mm Grinding area: 8,0 to 80 mm 30 to 120 mm 30 to 180 mm 3.

2 DDS XR Three grinding methods meeting different production problems: 1. Through-feed grinding For large mass-production >2000 parts per hour and accuracy requirements of 0,002 to 0,020 mm for workpiece dimensions with Machine size: DDS 457 XR DDS 600 XR DDS 750 XR Grinding size: 1,0 to 20 mm 2,0 to 20 mm 5,0 to 30 mm Grinding area: 8,0 to 80 mm 30 to 120 mm 30 to 180 mm 2. Through-feed plunge-cut grinding For medium size production of about 600 to 2000 parts per hour and accuracy requirement of <0,005 mm for workpiece dimensions with Machine size: DDS 457 XR DDS 600 XR DDS 750 XR Grinding size: 1,0 to 20 mm 2,0 to 20 mm 5,0 to 30 mm Grinding area: 8,0 to 80 mm 30 to 120 mm 30 to 180 mm 3. Plunge-cut grinding with controlled rotation of the workpieces For medium size production and small batches, high stock removal and high accuracies for workpiece dimensions with Machine size: DDS 457 XR DDS 600 XR DDS 750 XR Grinding size: 2,0 to 80 mm 2,0 to 80 mm 5,0 to 80 mm Grinding area circle: max. 205 mm max. 250 mm max. 300 mm All grinding methods working with grinding wheels, rings, segments of conventional grits or CBN- or Diamond-wheels: CBN- and Diamond-Wheels Grinding rings together with back up plates DKS-Grinding segments

3 DDS 600 XR DDS 600 XR DDS 750 XR Two machines DDS 600 XR for pregrinding of stamps and finish grinding of these gear parts after hardening, and one machine DDS 750 XR for flexible production of conrods. Rotating buffer for ground parts The machines DDS... XR with vertical grinding spindles are specially designed for the grinding of thin flat workpieces on both parallel sides without clamping. Work pieces of a greater grinding area and high stock amounts can be ground in one step to tight tolerances of thickness, parallellity, flatness and surface roughness. Different handling systems depending on workpiece shape and size, and on production requirements, can be added! The machine type DDS... XR is an ideal design for automatic loading/unloading. Our Engineering-Team can advice on the connection of the machines to existing production lines. Workpiece handling with 6-axis-robot... vibration transport... stack feeder system
