CK5355/75 is a flat bed, integral bed base, rear chip layout structure independently developed by our company. X and Z directions are rectangular guide rails, the lead screw is placed in the middle, the guide rail is fully protected, and the main shaft is manually shifted in three gears. Heavy cutting CNC lathes. It is especially suitable for heavy cutting and efficient machining of disc parts such as valves, sprockets, gears and flanges.
Machine Features
●All castings are cast by resin sand process, with beautiful appearance. All castings are subjected to secondary aging, with small thermal deformation and stable precision.
●The overall bed base has better waterproof performance; after chip removal, it is more suitable to form an automatic production line.
●X/Z direction adopts rectangular cast iron hardened guide rail, with large guide rail span (Z direction 430mm/X direction 280mm) guide rail system has stronger rigidity, better guidance, higher precision and better sliding performance.
●Main drive system, driven by frequency conversion or servo motor, Manual three-speed speed change, retains the characteristics of high torque turning, especially suitable for heavy cutting.
● The X/Z feed system adopts the screw center structure, advanced center of gravity drive technology (DMG), screw pre-stretching technology, and direct connection technology to achieve faster transmission speed and higher positioning accuracy.
●Two types of carriages and slides, one with single tool rest and one with double tool rest. You can also choose single tool holder + row tool, plus U drill and other configurations.
●X/Z-direction guide rail and lead screw adopt full protection structure, which has good chip removal and waterproof performance, reduces the wear of guide rail and lead screw, and improves the service life of guide rail and lead screw.
