Fast-indexing Centurial CNC cutoff lathes from Modern Machine Tool Co., which is celebrating its 100th anniversary, can automatically load, cut off, chamfer, turn, bore, thread, drill and unload in one quick cycle. This versatile family of cutoff lathe machines combines CNC technology with many of Modern Machine Tool's most popular, production-proven design features.

Features:

EASY SET-UP AND FAST CHANGEOVER – Programmable setting of tools, feed rates and spindle speeds.

STANDARD CARBIDE INSERT TOOLING for turning and boring, in place of expensive form tools.

GE-FANUC CONTROLLED with CRT monitor and operator control panel. (Allen-Bradley CNC is available as an option.)

TWO CROSS SLIDES are fed by independent servo drives and ball screws. The single-axis cutoff slide moves perpendicular to the spindle, while the second slide has two axes of motion for turning, boring and threading. The X axis moves perpendicular to the spindle, the Z axis parallel.

COMPLEX FORMS can be turned by coordinating the movement of X and Z axes using the CNC control, eliminating the need for form tools.

PART LENGTH STOP is power clamped on an overhead beam and moved by a ball screw and hand crank. The stop travels on linear bearings and is positioned using a digital readout with a linear scale.

THE STOP RETRACTS clear of the stock after the collet closes, permitting easy automated unloading of machined parts.

SPINDLE DRIVE – 30 HP digital servo spindle drive. Standard CNC assures uniform surface speed. A 40 HP spindle drive is optional.

AUTOMATIC FEEDER holds large bundles of tube, pipe and bar stock.

STANDARD EQUIPMENT includes a roller feed assembly, circulating oil lubrication of main spindle bearings, high volume coolant pump and piping, fused disconnect and cycle counter.

OPTIONAL DISC-STYLE TOOL TURRET can be supplied for multiple operation tooling.

OPTIONAL SERVO-POSITIONED STOP allows precise positioning of the part length stop using the CNC, with offset control.
