Introducing the Acra Precision High Speed & High Accuracy Tool Room Lathe with Inverter, a game-changer for tool makers seeking unparalleled performance and versatility. This state-of-the-art lathe is designed to meet the demands of continuous production while delivering exceptional precision and speed.

The Acra Precision High Speed & High Accuracy Tool Room Lathe with Inverter is a testament to engineering excellence. With its rugged construction, this lathe is built to withstand the rigors of non-stop production. Boasting a generous 280 mm (11") swing over bed and a 457 mm (18") distance between centers, it provides ample working space for a wide range of projects.

One of the standout features of this lathe is its dual range Inch/Metric quick change gearbox, allowing for seamless switching between measurement systems. The infinitely variable spindle speeds, ranging from 0 to 4,000 RPM, enable optimal cutting performance for various materials and applications. The fast lever collet chucking system ensures quick and easy workpiece changes with a single movement.

The automatic thread length control with fine adjustable stops guarantees accurate thread relief, while the full bearing carriage with Turcite-B slideway bearing material between carriage and bed provides smooth and precise movement. The solid hardened and ground alloy tool steel bed offers exceptional stability and durability. The spindle, mounted in high precision preloaded angular contact ball bearings, eliminates end play and ensures uncompromising accuracy.
