2. Numerical control device: including hardware and corresponding software. Function: It is used to input digital parts programs, and complete the storage of input information, data conversion, interpolation operation and various control functions.
3. Driving device: including spindle driving device, feeding device, spindle motor and feeding motor, etc. Function: under the control of numerical control device, he realizes spindle and feed drive through electric or electro-hydraulic servo system. When multiple feeds are linked, positioning, straight line, plane curve and space curve can be processed. ?
4. Auxiliary equipment: refers to some necessary supporting parts of CNC machine tools. Function: used to ensure the operation of CNC machine tools, such as cooling, chip removal, lubrication, lighting, monitoring, etc. It includes hydraulic and pneumatic devices, a chip removal device, an exchange workbench, a numerical control turntable and a numerical control indexing head, as well as a cutter and a monitoring detection device.
5, programming and other auxiliary equipment. Function: It can be used to program and store parts outside the machine.
1.CNC machine tool is the abbreviation of computer numerical control machine tool, and it is an automatic machine tool with program control system. The control system can use control codes or other symbolic instructions to logically process, decode and express the program with coded numbers, and input it into the numerical control device through the information carrier. After the operation, the numerical control device sends out various control signals to control the action of the machine tool, and automatically processes the parts according to the shape and size required by the drawings.
Numerical control machine tool solves the processing problem of complex, precise, small batch and multi-variety parts. It is a flexible and efficient automatic machine tool, which represents the development direction of modern machine tool control technology and is a typical mechatronics product.
Second, the characteristics:
1, which 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 mold manufacturing;
2. High processing precision and stable processing quality;
3, multi-coordinate linkage can be carried out to process parts with complex shapes;
4, processing parts change, generally only need to change the numerical control program, can save production preparation time;
5. The machine tool itself has high precision and rigidity, and can choose favorable processing dosage and high productivity (generally 3~5 times that of ordinary machine tools);
6. The machine tool is highly automated, which can reduce the labor intensity;
