ZMMBG CU 730RD X 1000 MANUAL LATHE

Technical Description

The ZMMBG CU 730RD X 1000 is a versatile universal manual lathe engineered for precision turning operations across diverse industrial applications. This machine features a robust 730mm swing capacity over the bed, accommodating workpieces up to 28.74 inches in diameter, with a maximum center distance of 1000mm (39.37 inches), expandable to 5000mm with optional configurations. The spindle bore measures 103mm (4.06 inches) with a Metric 120 taper, delivering a hardened and precision-ground design balanced for high-speed and heavy-duty machining regimes. Equipped with an 11 kW (14.75 HP) main motor, the lathe achieves a maximum spindle speed of 1,250 RPM across 21 discrete speed ranges, providing optimal cutting velocities for various materials and operations. The carriage assembly includes a cross slide with 390mm travel and a top slide with 130mm travel, enabling precise tool positioning with a swing over cross slide of 19.69 inches. Threading capabilities are comprehensive, supporting 64 thread specifications including metric ranges from 0.5-120mm, inch threads from 60-1/4 TPI, modular threads from 0.125-30, and DP threads from 240-1. The machine incorporates a stable, ribbed headstock casting with a Morse No. 5 tailstock quill (90mm diameter), while precision-ground induction-hardened gears operate in an oil bath for extended service life. The 400mm bed width and DIN 55027 spindle nose facilitate direct mounting of standard 3-jaw self-centering and 4-jaw independent chucks, making this lathe suitable for job shop, maintenance, and prototype manufacturing environments.
