The IG 482 SD is packed with innovative features making it more powerful, precise, and most importantly, even easier to use. The touchscreen HMI controls feature a bright and easy to read display with new features such as automatic maintenance reminders, pre-loaded instruction manuals and PDFs, and an internal memory for repeatable process automation. DCM advanced technology has been added so you can improve your process time, reduce part damage, and easily train your team.

The IG 482 SD comes standard with all of the features of other DCM style grinders such as a variable speed grinding spindle motor and electromagnetic chuck, thru-spindle vacuum/pressure port, integral mist collection and coolant filtration system, and manual pulse generator for precise positioning.

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.
