MIDAS Series OD Grinder
High production multi-spindle grinding

The Weldon Midas series of CNC cylindrical grinders are designed to satisfy high production applications either between centers or in a chucking mode. These machines also provide the flexibility to grind a variety of part configurations with minimal set-up. Rotary and linear axes are sealed from airborne contaminates providing unmatched longevity in carbide and ceramic grinding applications.

Available with either a straight, angular or turret style wheelhead, the Weldon Midas machines can grind outside diameters, shoulders, faces, tapers, and radii, sometimes in a single set-up. Properly equipped, a Weldon Midas is ideally suited for high speed “Peel” grinding with CBN abrasives. Additionally, a programmable “C” axis package can be provided to accommodate non-round grinding applications.

Typical applications include bearing shafts, gear shafts, spindles, hydraulic spools, crankshafts, camshafts, wheel hubs, and large bushings.
