This series of horizontal CNC lathes integrates intelligent control technology and advanced manufacturing technology, with high precision, high efficiency and high cutting rigidity. Finite element analysis software is used to optimize the design, analyze the distribution of stress points, reduce the deformation of parts, and achieve the optimal structure of the whole machine. The main castings are all made of high-strength cast iron materials to ensure that vibration during the cutting process is minimized. At the same time, the machining accuracy and cutting stability are improved.
