The Mägerle MFP 50 5-axis CD (continuous dressing) grinding center from United Grinding Technologies Inc. has an automatic grinding wheel and tool changer. The ATC can switch the wheel or tool in 8 seconds using a swing-arm configuration. Maximum tool dimension is 300mm × 60mm × 76.2mm. An HSK-80 wheel flange provides the needed rigidity and precision for producing tight-tolerance parts with fine surface finishes, according to the company. The machine is equipped with an overhead-mounted, 2-axis, CD diamond dresser with horizontal and vertical NC axes to accommodate several diamond rolls.
