Technical Description
The BOCHI BJ1840G Manual Lathe is a robust and versatile engine lathe designed for precision turning operations in industrial and workshop environments. Featuring a 18-inch swing and a center distance of 39.3 inches, this lathe accommodates medium to large workpieces, making it suitable for a wide range of machining tasks. The spindle bore measures 2 inches, allowing for the passage of long bar stock or specialized tooling, enhancing its flexibility for various applications. The machine delivers a maximum spindle speed of 2,000 RPM, providing efficient cutting performance for both roughing and finishing operations on a variety of materials, including steel, aluminum, and brass. Swing over the cross slide is 11.3 inches, ensuring ample clearance for tooling and workpiece manipulation during complex machining cycles. Constructed with a heavy-duty cast iron bed and hardened ways, the BJ1840G ensures high rigidity, minimal vibration, and long-term accuracy even under demanding conditions. The manual control system offers direct operator input for precise adjustments, ideal for custom or low-volume production runs. The lathe’s headstock houses a powerful drive motor and gear system, enabling variable speed control to match the requirements of different materials and cutting tools. The tailstock provides additional support for long workpieces and can be used for drilling or taper turning operations. The carriage assembly, comprising the saddle, cross-slide, and apron, facilitates accurate linear movement for turning, facing, and threading with high dimensional consistency. This lathe is well-suited for general-purpose machining, repair work, and prototyping, combining durability, precision, and ease of operation in a compact footprint.
