ZMMBG CU 730RD X 4000 MANUAL LATHES

Technical Description

The ZMMBG CU 730RD X 4000 manual lathe is a versatile heavy-duty machine designed for precision turning operations. It features a maximum swing over bed of 28.74 inches (730 mm) and a maximum distance between centers of 157.48 inches (4000 mm), enabling it to handle large and long workpieces. The spindle bore diameter is 4.06 inches (103 mm), allowing for substantial bar capacity. The lathe’s headstock incorporates a hardened and precisely ground spindle with a DIN 55027 nose and Camlock attachment system, facilitating quick tool changes and reliable chuck mounting. It operates with a powerful 14.75 HP (approximately 11 kW) motor, delivering spindle speeds ranging from 12.5 to 1,250 RPM across 21 speed settings for optimal cutting conditions. The swing over the cross slide is 19.69 inches (500 mm), permitting machining close to the tool post. The bed is robustly constructed with a 400 mm width for rigidity, minimizing vibrations during heavy-duty cutting tasks. This lathe supports a wide range of threading capabilities with up to 64 thread types, including metric, inch, module, and diametral pitch threads, driven by 120 feed options for precise longitudinal and cross-feed control. The cross slide travel is approximately 390 mm with a top slide travel of 130 mm, allowing versatile tool positioning. The tailstock quill has a diameter of 90 mm and uses a Morse taper No. 5 for secure tool holding. Gears are induction hardened and operate in an oil bath, ensuring durability and smooth operation. Overall, the CU 730RD X 4000 is engineered for robust performance, accuracy, and flexibility in manual turning applications.
