SHANDONG SANZHENG Q1319—1B MANUAL LATHES

Technical Description

The SHANDONG SANZHENG Q1319-1B is a manual engine lathe designed for medium to heavy-duty turning operations, offering a swing over bed of 24.8 inches and maximum centers length of 59.1 inches, enabling it to accommodate large workpieces. The spindle bore measures 7.9 inches, allowing it to pass reasonably sized stock through the spindle for extended work. Powered by a 10.1 HP motor, the lathe can achieve spindle speeds up to 300 RPM, suitable for rough turning and facing of large diameter parts. The swing over cross slide is 13.8 inches, defining the maximum workpiece diameter manageable above the cross slide area, accommodating various cutting tasks. The construction likely includes a robust cast iron bed to provide stability and vibration damping, essential for precision and durability in manual machining environments. Key components such as the spindle are supported by preloaded bearings in the headstock, ensuring consistent rotation and alignment. The lathe enables standard turning, facing, boring, threading, and related machining operations with manual feed controls. Its specifications position it as a versatile machine suitable for workshop, prototyping, and repair applications requiring significant capacity and power for larger workpieces. The manual operation relies on handwheels and mechanical feeds for carriage and cross slide movements, suitable for skilled machinists focused on one-off or short-run production tasks that require adaptability rather than automation. Overall, the Q1319-1B offers a combination of power, capacity, and rigidity to handle demanding turning projects in traditional lathe applications.
