The Acer e-Lathe 1740G represents a significant step forward in engine lathe technology, combining the robust mechanical structure of a precision lathe with the efficiency and flexibility of a variable speed drive. This machine features a substantial capacity with a 17-inch maximum swing over the bed, a 26-inch swing in the removable gap, and 40 inches between centers. The headstock incorporates a revolutionary design with fewer gears than conventional models, reducing maintenance and minimizing potential downtime.

The lathe is powered by a highly efficient 7.5 HP spindle motor that accepts both single and three-phase power. It delivers an infinite range of spindle speeds from 25 to 2,200 RPM across three mechanical gear ranges, allowing operators to achieve the optimal speed for any cutting condition. Speed changes are remarkably fast, taking approximately 4 seconds. The headstock is designed for high torque output and features a spindle nose of D1-6 camlock with a 2-1-4 inch spindle bore. Key advantages of the e-Lathe include the ability to easily adjust spindle speed during cutting, an accurate RPM reading to prolong tool life, and energy savings of up to 35 percent. For safety, the machine includes an electronic and mechanical brake for fast spindle stops, which is crucial for internal threading. The lathe is constructed with hardened and ground bedways and features a quick-change gearbox for a wide range of Inch (4-56 TPI) and Metric (0-5-7 mm/pitch) threading without requiring gear changes.
