SIDNEY TYPE H.D. MANUAL LATHES

Technical Description

The Sidney Type H.D. Manual Lathe features a 15-inch spindle size with a maximum center-to-center distance of 72 inches, making it suitable for large workpieces. It accommodates a maximum swing of 14 inches over the carriage and 22 inches over the ways, providing versatility in machining diameter sizes. The lathe is equipped with a taper attachment and two steady rests to support long or slender workpieces during operation. Threading is inch-based, catering to common threading standards. Powered by a robust 10 HP motor, the spindle speed ranges from 12 to 360 RPM, offering a broad speed range for various metal cutting applications. This lathe’s construction ensures durability and precision for heavy-duty manual turning tasks. Its mechanical design typically includes features like continuous tooth herringbone gears and multiple speed/feed changes, common to Sidney lathes, ensuring smooth operation and versatility in machining threads and feeds. The 10 HP power and relatively low spindle speed range indicate suitability for heavy material removal and roughing operations as well as fine finishing when required. The presence of taper attachment and steady rests adds to its functional flexibility, enhancing accuracy and reducing vibration during precise threading or turning of long shafts. Overall, the Sidney Type H.D. Manual Lathe is a capable machine for heavy-duty industrial applications requiring precise manual control over spindle speed, threading, and workpiece support.
