The new Magerle MFP 50 five axis grinding centre from United Grinding Technologies features an automatic grinding wheel and tool changer, representing one of the most flexible, multi-tasking CD grinders in the Magerle family, says the company.

The new MFP 50 includes an integrated automatic tool changer which can switch wheels in eight seconds using a swing arm configuration. Maximum tool dimensions are 300 mm x 60 mm x 76.2 mm, and wheel/tool changer capacity, depending on the diameter, is 10 to 30 conventional grinding wheels, plated or ceramic bonded CBN wheels as well as drilling and milling tools. A reliable HSK-80 wheel flange system offers rigidity and

precision needed 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 a proven overhead mounted two axes CD diamond dresser with horizontal and vertical NC axis for the accommodation of several diamond rolls with various profiles for CD or non-CD, as well as for CNC dressing with a disc. The grinding wheels with different profiles are always on the same spindle position.

Mägerle developed hydrostatic wrap-around guideways utilized in the Y axis. These are 100 percent wear-free and offer high rigidity and load capacity, optimum smoothness and vibration dampening and maximum precision and process reliability. All main axes of the MFP 50 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.
