GBI Cincinnati’s SMS CNC, high speed vertical turning centers are said to be ideal for mixed volume, short-run operations as well as dedicated high-volume applications.
With a swing of 650 mm and a maximum turning diameter and height of 610 mm and 505 mm, the SMS AC-600 combines high-performance turning and large machining capacity within a compact 1,700- × 1,600- × 12,942-mm footprint. X-axis travel is 306 mm and Z-axis travel is 505 mm. Both X and Z axes have glass scales for ensuring accuracy and machine stability. Rapid traverse rates of 15 m/min (in the X and Z axis) reduce non-cut time, which increases overall throughput. A power turret with a C-axis spindle also decreases cycle time. A slotted disc-type turret offers 0.25-second station-to-station indexing time and holds eight tools.
The centers feature a rigid Meehanite cast iron machine base and ribbed column for heavy-duty metal removal applications. High-speed linear guide rails and boxway construction as well as circulated cooling on motor bases increases machining accuracy, the company says.
A high-torque 30/40 kW AC Fanuc spindle motor with a variable speed drive permits full horsepower at low spindle speeds. The A2-11 spindle nose can turn at speeds ranging to 3,200 rpm. The headstock eliminates heat from the spindle bearings, which also prolongs the life of the bearings and ensures spindle reliability.
A hydraulically powered 15" three-jaw chuck is standard as well as an automated lubrication system, a complete coolant system and splashguards with overlapping doors. The electrical cabinet is fully enclosed and dustproof.
