CNC lathe is a machine tool for machining metals and other materials, which controls the movement of the table and tools by a computer or other digital device to achieve high precision and efficiency. Compared with traditional lathes.
Structural characteristics of CNC vertical lathe:
CNC vertical lathe is a CNC vertical lathe whose main structure is base and single column type structure with table, fixed beam, square ram and single tool holder structure, which is an economic CNC vertical lathe with high rigidity and high cost performance. The casting process of CNC vertical lathe is large in volume and complex in structure, the amount of iron liquid poured is large, the cooling time of the casting is long, and casting defects such as shrinkage, shrinkage, pore, crack and substandard mechanical properties are easy to appear, and it is difficult to control the production process. The base, column and beam of CNC vertical lathe are made of high-strength cast iron with good shock absorption; the large span hardened guide rail has good wear resistance and long-lasting precision maintenance. Symmetrical box structure can carry heavy cutting with high torque. The ram adopts square structure, with good precision. Fixed cross beam, good rigidity and high precision. CNC vertical lathe single tool block structure, stable and reliable precision. Centralized machine operation panel â—‡Makes the operation more convenient and quick. It can process various internal and external cylindrical surfaces, conical surfaces, circular curved surfaces, etc. CNC vertical lathe is suitable for processing parts such as motor shells, large and medium-sized disk sets and covers. It is suitable for electromechanical, automobile, wind power, engineering machinery and other industries.
