The ACER Dynamic 2660L is a precision manual engine lathe designed for heavy-duty machining. It features a 26.0-inch swing over the bed and a 17.3-inch swing over the cross slide, with a distance between centers of 59.0 inches, allowing for the machining of long and large diameter workpieces. The lathe is powered by a robust 10.1 HP motor, driving the spindle at speeds up to 1,500 RPM via a manual 12-step speed range. The spindle bore diameter is 3.30 inches, accommodating larger tooling and bar stock. The machine construction includes precision ground cross-slide ways, a saddle-lock device for stable heavy cutting, and four-direction rapid travel for enhanced usability. The headstock employs magnetic multiple-disc clutches for efficient spindle start and reversing, with D1-8 or D1-11 spindle nose compatibility. The tailstock spindle features a #5 Morse taper and 6.5-inch travel for versatile support of workpieces. Additional features include oil level and flood indicators, a handwheel with direct inch/metric reading micro-collar, an ampere meter for power monitoring, and a safety clutched longitudinal lead screw with 4 TPI and oil bath lubrication. The lathe includes an optional "Newall" 2-axis digital readout system for precise position feedback. Suitable for industrial and precision turning tasks, the ACER Dynamic 2660L combines sturdy construction, precise control, and reliable power for a versatile machining platform. Dimensions are approximately 114" x 41" with a substantial weight around 5,800 lbs, denoting its heavy-duty capabilities.
