Two new F series vertical machining centers from Makino are designed to handle large production parts and big die and mold components. They come standard with core-cooled ball screws and scale feedback.
The smaller F8 features X-, Y-, and Z-axis travels of 51.2, 31.5, and 25.6 in., respectively; a 61- by 31.5-in. table; and a maximum workpiece size of 61 by 31.5 by 21.7 in. The larger F9 features X-, Y-, and Z-axis travels of 63, 31.5, and 25.6 in., respectively; a 72.8- by 31.5-in. table; and a maximum workpiece size of 72.8 by 31.5 by 21.7 in. Both machines offer a payload capacity of 5,510 lbs. and feature a 30-tool-capacity automatic tool changer.
The standard spindle configuration is a 49.6-HP, 10,000-RPM, CAT 50 spindle. As an option, the spindle also can be provided with an HSK-A100 spindle interface. With 315 ft.-lbs. of torque, this combination provides stiffness and rigidity for lower-speed roughing operations and a mix of spindle speed, power, and torque. A 40.2-HP, 20,000-RPM HSK-A63 spindle is optional.
