What is CNC Machine?
A CNC machine is an automated machine equipped with a program control system. The control system can logically process programs with control codes or other symbolic instructions, decode them, express them with coded numbers, and input them into the numerical control device through the information carrier. After calculation and processing, the CNC device sends out various control signals to control the movement of the machine and automatically process the parts according to the shape and size required by the drawing. CNC machines can better solve the problem of complex, precise, small batch and multi-variety parts processing. CNC machines are flexible, high-performance automation equipment that represents the development direction of modern machines and is a typical mechatronics product.
- It has strong adaptability to processing objects, adapts to the characteristics of single-piece production of molds and other products, and provides suitable processing methods for the manufacturing of molds;
- High processing precision and stable processing quality;
- Multi-coordinate linkage is possible and parts with complex shapes can be processed;
- When processing parts change, generally only the CNC program needs to be changed, which can save production preparation time;
- The machine tool itself has high precision and rigidity, can choose favorable processing amounts, and has high productivity (generally 3 to 5 times that of ordinary machine tools);
- The machine tool has a high degree of automation, which can reduce labor intensity;
- Conducive to the modernization of production management. CNC machine tools use digital information and standard codes to process and transmit information, and use computer control methods, laying the foundation for the integration of computer-aided design, manufacturing and management;
- There are higher quality requirements for operators and higher technical requirements for maintenance personnel;
- High reliability.
The basic components of CNC machine include processing program carriers, CNC devices, servo drive devices, machine tool main bodies and other auxiliary devices.
The machining center is a highly automated multi-functional CNC machine tool with a tool magazine and an automatic tool changer. After the workpiece is clamped once on the machining center, it can process multiple processes on more than two surfaces, and has multiple tool changing or tool selection functions, thus greatly improving production efficiency. Machining centers are divided into two categories: boring and milling and turning according to their processing procedures. According to the number of control axes, they can be divided into three-axis, four-axis and five-axis machining centers.
CNC turning machining center adds a C-axis and power head to the ordinary CNC lathe. Due to the addition of C-axis and milling power head, the processing functions of ordinary CNC lathes have been greatly enhanced. In addition to general turning, precision CNC turning can also be performed, such as radial and axial milling, plane milling, holes whose centerline is not at the center of rotation of the part, radial hole drilling, etc.
