ACME LATHE EXD/4 MANUAL LATHES

Technical Description

The ACME LATHE EXD/4 is a manual lathe designed for precision machining with a substantial work capacity. It features a **31.1-inch swing**, allowing it to machine relatively large diameter workpieces efficiently. The **distance between centers is 89.8 inches**, enabling it to handle long shafts or bars. The spindle bore diameter is **3.1 inches**, accommodating substantial stock material through the spindle for operations like turning and threading. It operates at a maximum spindle speed of **500 RPM**, suitable for work requiring high torque rather than high-speed cutting. The swing over the cross slide is **19.7 inches**, indicating the maximum diameter of a workpiece that can pass over the cross slide, important for tool positioning and access during turning tasks. This lathe is optimized for handling heavy-duty workpieces and tasks such as threading with Acme or trapezoidal thread forms, common in leadscrew and power transmission applications due to their 29° thread angle and robust profile, offering strength and ease of machining. Its combination of large swing, long centers, and moderate spindle speed makes it well-suited for applications requiring durable, precision machining with moderate rotational speeds, such as in manufacturing shafts, large screws, or heavy threaded components.
