TJ CKJ6115 MANUAL LATHES

Technical Description

The TJ CKJ6115 is a heavy-duty engine lathe designed for precision turning operations on large workpieces. This machine features a substantial swing capacity of 49.1 inches and an extended center distance of 196.5 inches, making it suitable for extended cylindrical work. The spindle bore measures 3.9 inches, accommodating various tooling configurations. Powered by a robust 30.0 HP motor, the lathe delivers consistent performance across its operational range. The swing over cross slide is 32.6 inches, providing adequate clearance for complex turning operations. Despite its manual classification, the machine is equipped with CNC control via a Siemens 802D control system, enabling programmable operation and enhanced precision. The low RPM rating of 2 RPM indicates this machine is optimized for heavy-duty roughing operations and large-diameter workpieces rather than high-speed finishing work. The substantial footprint of 318.9 x 97.2 x 78.7 inches and weight of 31,200 lbs reflects its industrial-grade construction and rigidity necessary for demanding machining tasks. This lathe is ideal for manufacturing environments requiring precision work on large components, including shafts, drums, and other cylindrical parts where both accuracy and material removal rate are critical.
