You can go from milling to grinding in one machine, you’re not only saving on capital equipment, but you’re also able to perform several operations in a single setup, eliminating all of the out-of-cut time that does nothing but add to your costs and lead-time.

These capabilities make the G7 an ideal solution for Inconel® grinding, nickel-based alloy grinding, root-form grinding and other materials common to aerospace turbine blade-and-vane grinding operations.
