ACER DYNAMIC 22120L MANUAL LATHES

Technical Description

The ACER Dynamic 22120L is a precision manual engine lathe engineered for heavy-duty production and job shop applications. Featuring a 22-inch swing over bed and 118-inch distance between centers, this machine accommodates large workpieces with exceptional rigidity and accuracy. The spindle bore of 3.3 inches supports various tooling configurations, while the 13.4-inch swing over cross slide provides versatile cutting geometry. Powered by a robust 10 HP motor operating at 1,500 RPM, the lathe delivers consistent torque for demanding turning operations. The machine is constructed with a thermally treated Meehanite casting bed achieving HS70 hardness, ensuring dimensional stability and minimizing thermal distortion. Its universal gearbox offers a comprehensive range of cutting capacities accessible through intuitive lever-operated controls, supporting both inch and metric threading capabilities. The tailstock features MT5 taper compatibility with 6.5 inches of spindle travel, while the compound rest and cross slide provide 7.9 inches and 14.8 inches of travel respectively. The lathe accommodates D1-11 spindle nose options with spindle speeds ranging from 15 to 1,500 RPM across 12 steps, enabling optimization for various material conditions and cutting parameters. Additional features include automatic feed and threading with interlock protection against simultaneous operation, precision-ground bed ways, and optional digital readout systems for enhanced positional accuracy. The machine dimensions of 186 x 41 x 50 inches and 2,310 lbs weight provide substantial foundation stability for extended production runs requiring superior surface finish and tolerance control.
