1, The definition is different
CNC machine tool: CNC machine tool is the abbreviation of digital control machine tool. It is an automatic machine tool with program control system. The control system is capable of logically processing a program having control code or other symbolic instruction specifications, decodes it, and uses a coded digital representation to input the numerical control device through the information carrier. Through the arithmetic processing, various control signals are issued by the numerical control device to control the movement of the machine tool, and the parts are automatically processed according to the shape and size required by the drawings.
CNC lathe: CNC lathe is one of the most widely used CNC machine tools. It is mainly used for the inner and outer cylindrical surfaces of shaft parts or disc parts, the inner and outer conical surfaces of any taper angle, the complex inner and outer curved surfaces, the cylindrical and conical threads, etc., and can be used for grooving, drilling, reaming and reaming. Holes and borings, etc.
2. Features are different:
CNC machine tools: adaptability to the processing object, adapt to the characteristics of single-piece production of molds, etc., provide suitable processing methods for the manufacture of molds; high processing precision, stable processing quality; multi-coordinate linkage, can Machining parts with complex shapes; when machining parts are changed, generally only the NC program needs to be changed, which saves production preparation time.
The machine tool itself has high precision and rigidity, and can choose favorable processing quantity, high productivity (usually 3~5 times of ordinary machine tools); high degree of machine tool automation can reduce labor intensity; it is conducive to the modernization of production management. CNC machine tools use digital information and standard code to process and transfer information, and use computer control methods to lay the foundation for computer-aided design, manufacturing and management integration.
3, The composition is different
CNC machine tools: The basic components of CNC machine tools include machining program carriers, numerical control devices, servo drives, machine tool bodies and other auxiliary devices. The basic working principle of each component is outlined below.
CNC lathe: CNC lathe consists of CNC device, bed, spindle box, tool holder feed system, tailstock, hydraulic system, cooling system, lubrication system, chip conveyor and so on.
