Large-Workpiece Machining

April 1, 2010

The FJV-35/60 II from Mazak is a double-column vertical machining center designed for the high-speed, high-precision production of large workpieces.

Suitable for many industries, including aerospace, construction, die and mold, and heavy machine, the versatile machine can accommodate up to 5,500 lbs. on a 59.1-in. by 31.5-in. worktable.

A 50-taper, 40-HP, 10,000-RPM integrated spindle generates up to 433 ft.-lbs. of torque for the cutting of large, cast iron, steel, and aluminum workpieces, although the machine is also available with an optional 40-taper, 18,000-RPM, high-speed spindle.

The new machining center is available with a five-face machining option, which utilizes a spindle automatically indexable by 90 degrees, a special angle tool capable of automatic tool change (ATC), and an angle toolholder that can be indexed in four positions.

The machine is equipped with roller guides on all axes for increased rigidity, and these guides produce feed rates of 1,574 IPM in the X and Y axes and 1,181 IPM in the Z axis. The machining center’s direct-drive ball screw system can also produce roundness to 5 µm.

The machine’s Z-axis stroke is 25.98 in., which allows the machining of workpieces up to 25.20 in. tall.
