The SMTCL CA6240B manual lathe is a versatile horizontal engine lathe designed for precision metalworking tasks. It features a maximum swing over the bed of **15.75 inches (400 mm)** and a spindle bore of **3.54 inches (90 mm)**, allowing it to accommodate sizable workpieces. The lathe is powered by a robust **10.06 HP (7.5 kW)** spindle motor, capable of reaching speeds up to **1,400 RPM** across multiple steps, ensuring flexibility in machining various materials including steel, cast iron, and nonferrous metals. The swing over the cross slide is **8.27 inches (210 mm)**, supporting the machining of smaller diameter components with precision. Its heavy-duty construction includes a 400 mm wide bed with hardened and quenched rails for durability and accuracy. The tool post accommodates a **25×25 mm** section turning tool, suitable for various cutting operations. The lathe is engineered for internal and external cylindrical surfaces, conical surfaces, end faces, and threading (metric, inch, modular, and radial pitch threads). It also supports auxiliary operations such as drilling, reaming, and groove cutting. High dimensional accuracy up to IT7 tolerance and fine surface finishes are achievable due to the solid build and precise spindle assembly. The lathe includes a sensitive and reliable manual braking system for operator safety and control during operation. Forced lubrication ensures long-lasting performance of moving parts. Overall, the SMTCL CA6240B is a robust choice for precise, manual machining applications in both industrial and workshop settings.
