SANHUANJIAN CW6/2125E(F)/7000 MANUAL LATHES

Technical Description

The SANHUANJIAN CW6/2125E(F)/7000 is a heavy-duty manual engine lathe designed for precision turning operations in industrial applications. This machine features a maximum swing of 49.21 inches over the bed, accommodating large workpieces up to 275.59 inches between centers. The spindle bore measures 4.13 inches with a metric 140 taper, providing robust capability for various cutting tools and work-holding accessories. Powered by a 22 kW main motor, the lathe delivers 14.75 HP with spindle speeds ranging from 3.15 to 315 rpm across 21 steps, allowing optimal speed selection for diverse materials and operations. The machine incorporates 56 different feed rates with cross-slide feeds of 0.1-12 mm per spindle rotation and longitudinal feeds of 0.05-6 mm per spindle rotation, enabling precise control over thread cutting and surface finishing. The bed width of 755 mm provides stability during heavy-duty turning, while the rapid traverse rates reach 3,470 mm/min longitudinally and 1,870 mm/min in the cross direction. Additional features include a MT6 tailstock with ±25 mm movement, a 1.5 kW carriage rapid motor, and a 90 W coolant pump with 45 L/min flow capacity for efficient chip evacuation and tool cooling. The lathe accommodates 4-jaw chucks up to 1,250 mm and supports maximum center loads of 8,000 kg. Surface finish capabilities achieve roughness values of 3.2 μm, making this machine suitable for both rough turning and precision finishing work across manufacturing, aerospace, and heavy industrial sectors.
