CJM320B Industrial Light Duty Bench Lathe

CJM320B Industrial Light Duty Bench Lathe | 600mm / 750mm Turning Length

Product Overview:

The CJM320B is a large-capacity industrial-grade light duty bench lathe designed for small to medium batch production, machinery maintenance, vocational training and precision prototyping. With a 320mm swing over bed and up to 750mm between centers, it offers significantly larger machining capacity while retaining a compact bench-top footprint, making it ideal for workshops requiring both versatility and space efficiency.

Built with a full gear-driven spindle headstock and widened high-frequency hardened bed ways, this machine delivers strong cutting rigidity, stable long-term accuracy and reliable heavy-duty performance. It is equipped with a 12-speed feed gearbox, automatic longitudinal and cross feeds with safety interlock, and comprehensive threading capability, covering metric, imperial, module and diametral pitch threads for diverse machining applications.

Key Features:

• Full Gear-Driven Spindle Headstock: 12-step speed range provides consistent torque output across all speeds, ensuring stable cutting performance and extended service life for continuous workshop operation.
• Extensive Thread Cutting Range: 12-range feed gearbox covers 22 metric threads (0.2–7.0mm), 45 imperial threads (2½–48 TPI), 21 module threads (0.2–3.5 MP) and 31 diametral pitch threads (8–120 DP), accommodating a wide range of threading requirements.
• Automatic Feeds with Safety Interlock: Powered longitudinal and cross feeds improve machining efficiency; built-in mechanical interlock mechanism prevents misoperation and enhances operator safety.
• Widened High-Rigidity Guideways: Double-flat & double-vee widened bed ways with high-frequency quenching provide excellent rigidity and superior long-term accuracy retention under heavy cutting loads.
• Industrial-Grade Operating Structure: Inclined wedge type tool post carriage, cam-locking tailstock and industrial machine control levers ensure precise positioning, smooth operation and durable heavy-use performance.
• Enhanced Machining Capacity: 320mm swing over bed, up to 750mm turning length and 1.1kW motor enable processing of larger workpieces with stable material removal rates.
