ACER DYNAMIC 2140S MANUAL LATHE

Technical Description

The ACER Dynamic 2140S manual lathe is a precision engine lathe designed for high-performance machining with a 20.5-inch swing and 39-inch distance between centers, allowing for the handling of large workpieces. It features a robust 3.1-inch spindle bore with a D1-8 camlock spindle nose and a maximum spindle speed of 2,000 RPM across 12 variable speeds, providing versatility for different cutting operations. Powered by a 7.5 HP motor, it delivers substantial torque for consistent, heavy-duty cutting. The machine incorporates a 13.0-inch swing over the cross slide and a 10.8-inch cross slide travel, supported by a thermal-treated Meehanite cast iron bed hardened to HS70, ensuring minimal vibration and enhanced precision. The gearbox supports quick-change threading with both inch and metric capabilities, covering a broad range of thread pitches (inch 4-56 TPI and metric 0.5-7 mm pitch). The tailstock includes a barrel diameter of 2.7 inches with 5.9 inches travel, taper fitting MT4, enhancing support for long workpieces. Additional features include automatic longitudinal multiple feed stops, heat-treated and precision-ground alloy gears, and an integrated 1/8 HP coolant pump motor. The lathe is built for durability and accuracy, with hardened bed ways and an overall solid construction suitable for demanding industrial environments. Its compact footprint measures approximately 85" x 32" with a shipping weight around 3,685 lbs, making it a reliable choice for precision metal turning applications.
