JOHNFORD ST 70A CNC LATHE

Technical Description

This 2-axis CNC lathe is a versatile turning machine equipped with a 12-inch chuck and capable of accommodating bar stock up to 2.5 inches in diameter. The machine features a maximum swing of 31.6 inches over the bed, allowing it to handle workpieces with substantial diameters for turning operations. With a machining length of 69 inches, the lathe provides significant longitudinal travel capacity, enabling the production of extended components. The spindle is powered by a 26 HP motor with a maximum rotational speed of 3,000 RPM, delivering adequate cutting power and speed for efficient material removal across various applications. The integrated tailstock provides essential support for long workpieces during drilling and turning operations, enhancing stability and precision. As a CNC-controlled system, the machine utilizes computerized numerical control for automated, precise machining with programmed tool movements along X and Z axes. This configuration enables consistent repeatability and accuracy for production runs. The 2-axis design—comprising cross-slide (X-axis) and longitudinal (Z-axis) movements—suits general-purpose turning, facing, and boring operations. The machine's specifications make it suitable for small to mid-size job shops and manufacturing facilities requiring reliable precision turning capabilities for diverse workpiece geometries and production volumes.
