The technical expertise or unique skills of CNC lathe workers cover many aspects. First of all, they need to strictly implement the requirements system of production site management to ensure product quality and be responsible for processing quality. Secondly, they need to be proficient in drawing technology and technical requirements, and be able to master and operate CNC lathes and ordinary lathes skillfully. Daily maintenance and inspection of equipment and instruments to ensure their normal operation is also one of their key technologies. In addition, they also need to have certain programming ability, and can use CAD/CAM software to design and program parts.

CNC lathe is the work of machining by CNC lathe.

A, CNC machine tool is the abbreviation of CNC machine tool, is a kind of automatic machine tool with program control system. The control system can use control codes or other symbolic instructions to logically process and decode the program, so as to make the machine tool move and process parts. ?

Second, the characteristics of CNC machine tools

The operation and monitoring of CNC machine tools are completed in this CNC unit, which is the brain of CNC machine tools. Compared with ordinary machine tools, CNC machine tools have the following characteristics:

1, high machining accuracy and stable machining quality; ?

2, multi-coordinate linkage can be carried out to process parts with complex shapes; ?

3, processing parts change, generally only need to change the numerical control program, can save production preparation time; ?

4. 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); ?

5, the machine tool has a high degree of automation, which can reduce the labor intensity; ?

6. The quality requirements for operators are higher, and the technical requirements for maintenance personnel are higher.

1. CNC machine tools generally consist of the following parts:

1, host, which is the theme of CNC machine tools, including machine body, column, spindle, feed mechanism and other mechanical parts. It is a mechanical component used to complete various cutting processes. ?

2. CNC device is the core of CNC machine tools, including hardware (printed circuit board, CRT display, key box, paper tape reader, etc.). ) and corresponding software, which are used to input digital parts programs and complete the storage of input information, data conversion, interpolation operation and various control functions. ?

3. The driving device is the driving part of the executive mechanism of CNC machine tools, including spindle driving unit, feed unit, spindle motor and feed motor, etc. Under the control of numerical control device, he realizes the 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 device, refers to some necessary parts of CNC machine tools, 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 can be used to program and store parts outside the machine.
