Description

CK61160/200/220/250 (32/63) heavy-duty horizontal lathes can bear loads of up to 32 tons and 63 tons. They are suitable for using high-speed steel and carbide cutting tools to perform processes such as turning external circles, end faces, grooving, cutting off, boring holes, turning internal and external tapers, and various threads on shaft parts, disc-shaped parts, and plate-like parts of different materials.

The bed is an integral, modified three rectangular guide rail structure, cast in one piece using high-grade HT (300) material, and has undergone a secondary aging treatment for good stability. The guide rail surface is wide (1600mm/2090mm), has good rigidity, and strong anti-vibration ability. It uses inlaid steel guide rails which are precision ground by an imported guide rail grinder, ensuring long life, high precision, and good retention.

The main drive mechanism of the machine tool is driven by a 75/144KW DC motor. It adopts a vortex magnetic voltage regulation hybrid speed control method. The total speed ratio is 1:22.2 (1:39.58). The mechanism's speed control has three stages (four stages for the 63-ton model). The combined mechanical and electrical speed control ratio is 1:200 (1:266), which allows the main spindle to achieve a stepless speed range of 0.16～160 (0.5～125) r/min.

The Z-axis feed system adopts an imported precision gear and rack structure, and the X-axis feed system adopts a high-precision ball screw to ensure the stability of the machining accuracy.
