United Grinding’s Mägerle MFP 50 five-axis CD grinding center is a flexible multitasking grinder that features an automatic grinding wheel and toolchanger. The grinder is the smallest in the Mägerle machine line and can be configured for a variety of operations. Typical applications include turbine vanes and blades, small turbine and compressor blades, fir tree and root shank faces, and shroud and Z-notch profiles, both sides and slots if required.
Maximum tool dimensions measure 300 × 60 × 76.2 mm. Depending on the diameter, wheel/toolchanger capacity is 10 to 30 conventional grinding wheels, plated or ceramic bonded CBN wheels, and drilling and milling tools. An HSK-80 wheel flange system provides rigidity and precision for close-tolerance parts with high-surface-finish requirements. Tool options include vitrified CBN, plated CBN, conventional grinding wheels and various other metal cutting options.
The machine is equipped with an overhead-mounted two-axis CD diamond dresser with horizontal and vertical NC axis to accommodate several diamond rolls with various profiles for CD and non-CD, as well as for CNC dressing with a disc. The grinding wheels with different profiles are always on the same spindle position.
The machine features hydrostatic wrap-around guideways in the Y axis. The guideways are said to be wear-free and offer high rigidity and load capacity, optimized smoothness and vibration damping, and high precision and process reliability. All main axes can rapid traverse at 20,000 mm/min. (790 ipm). X-axis travel is 500 mm, Y-axis spindle travel is 660 mm and Z-axis travel is 660 mm. The grinder is equipped with Siemens Sinumerik 840D digital controls.
