For everything turn, turn, turn.
The C100 series of production turn-mill centers can come with an
optional Fanuc 31i CNC. With three 14-position tool turrets and
identical main and counterspindles, the machine is designed for
production of medium-complexity parts turned from bar stock from 30 to
42mm in diameter. The three-turret machine has a small floor footprint,
and is targeted to handle fixed headstock work often run on Swiss-type
machines. The machine includes 42 quick-change tools, fixed and driven.
The C100 with 30mm bar capacity comes with 9,000 rpm spindles. The 42mm
bar capacity is available with 7,000 rpm spindles. Both versions can run
parts to 200mm long. Motorized main and counter spindles are identical
and liquid-cooled. Up to three tools can be at work simultaneously with
both Y axes and backwork at the same time. The counterspindle with a
driven Z-axis can be synchronized with travel of turret 3.
Counterspindle pick-up from the spindle takes 1.5 seconds. Simultaneous
machining with two Y axes, one at the main spindle and one shared
between the main spindle and also one at the counterspindle--each with
70mm travel--gives users the option to divide machining operations for
optimum machining efficiency and flexibility. Index Corp., Booth 1403
