The mechanical part of a CNC lathe is the core foundation of equipment operation. Its manufacturing and assembly accuracy directly determines the overall machining precision of the machine tool, and affects the performance of core electric control systems such as the numerical control electric system and servo system. It serves as a key guarantee for the stable, high-precision and high-efficiency operation of the equipment. The CNC lathe is equipped with a complete mechanical system, which mainly consists of the machine tool bed, spindle rotation mechanism, feed carriage mechanism, tool post changing mechanism, guide rail transmission mechanism, tailstock mechanism and lubrication system.
All components work in synergy to complete composite machining processes including turning, grooving, chamfering and thread machining for various precision workpieces. The machine tool bed is the basic load-bearing component of a CNC lathe. It is generally constructed with a high-strength integral box-type casting structure, featuring high rigidity, excellent shock resistance and non-deformation properties. As the mounting reference platform for all parts and components of the whole machine, the bed carries all working mechanisms including the spindle, carriage, tool post and transmission assemblies. Its flatness, rigidity and stability are closely related to the long-term machining accuracy and service life of the machine tool. It can effectively counteract vibration and cutting stress during machining, preventing machining errors caused by equipment deformation.
