Large Capacity. Precise Control.

The IG 480 SD is our largest capacity and most powerful DCM style rotary surface grinder. It features a 48” diameter electromagnetic chuck with configuration features of through table vacuum, air or hydraulic clamping. The variable speed 50HP grinding spindle provides exceptional grinding performance for both conventional and superabrasives.

The IG 480SD is configured with a sliding door enclosure, air/mist filtration and swarf system with continuous filtering of the coolant. Clean coolant results in repeatable grinding performance. The automated grinding control simplifies machine operation and ensures consistent grinding results.

Grinding Applications

DCM grinders outperform conventional surface grinders and are efficient for removing large amounts of material, while maintaining close tolerances and reducing process time. Features such as variable feedrate & spindle speed, single or multi-step grinding, and easily programmable grind processes make this machine an ideal platform for processing a wide range of materials.
