ZMMBG CU 730RD X 2000 MANUAL LATHE

Technical Description

The ZMMBG CU 730RD X 2000 Manual Lathe is a robust and versatile universal lathe designed for precision turning and heavy-duty machining operations. With a swing over bed of 28.74 inches (730 mm) and a distance between centers of 78.74 inches (2000 mm), this machine offers ample capacity for large workpieces. The spindle bore measures 4.06 inches (103 mm), enabling the processing of long bar stock, while the spindle nose conforms to DIN 55027 No. 11, supporting direct mounting of various chucks and faceplates. The lathe is powered by a 14.75 HP (11 kW) main motor, delivering consistent performance across a wide range of materials and applications. Spindle speeds are variable, ranging from 12.5 to 1,250 RPM, with 21 selectable speeds for optimal control in different machining regimes. The hardened, ground, and balanced spindle ensures high accuracy and minimal vibration during operation. The machine features a precisely ground gear train made from induction-hardened case-hardening steel, operating in an oil bath for durability and smooth power transmission. Feed options include 120 longitudinal and cross feeds, with longitudinal feed range from 0.04 to 12 mm/rev and cross feed from 0.02 to 6 mm/rev. The lathe supports a comprehensive range of threads, including metric (0.5–120 mm), inch (60–1/4 TPI), module (0.125–30), and DP (240–1). The swing over the cross slide is 19.69 inches (500 mm), providing flexibility for complex turning tasks. The tailstock quill has a diameter of 90 mm and a Morse No. 5 taper, ensuring secure workpiece support. The lathe’s rigid, ribbed bed construction and precise engineering make it suitable for demanding industrial environments.
