Processing program carrier

When precision CNC turning parts CNC machine tools work, workers do not need to directly operate the machine tools. To control precision CNC turning parts CNC machine tools, processing programs must be compiled. The precision CNC turning parts processing program includes the relative motion trajectory of the tool and the workpiece on the precision CNC turning parts machine tool, process parameters (feed amount, spindle speed, etc.), and auxiliary motions. The precision CNC turning parts machining program using certain formats and codes, a program that is stored on a carrier, such as a punched tape, a cassette tape, floppy disk, etc., through the input device of the CNC machine, the program information input into the CNC unit.

CNC device

The numerical control device is the core of precision CNC turning parts CNC machine tools. Modern numerical control device CNC forms are used, such devices typically use a plurality of microprocessors CNC, CNC functions implemented in the form of programmed software, also known as CNC software (Software NC). CNC system is a kind of position control system, it is based on the input data to interpolate the ideal trajectory, and then output to the execution parts to process the required precision CNC turning parts.

Servo and measurement feedback system

Servo system is an important part of precision CNC turning parts CNC machine tools, used to realize the feed servo control and spindle servo control of precision CNC turning parts CNC machine tools. The function of the servo system is to convert the command information received from the precision CNC turning parts numerical control device, after power amplification and shaping, into the precision CNC turning parts machine tool to execute the linear displacement or angular displacement motion of the parts. Since the servo system is the last link of precision CNC turning parts CNC machine tools, its performance will directly affect the accuracy and speed of precision CNC turning parts CNC machine tools and other technical indicators. Therefore, the servo drive device of precision CNC turning parts CNC machine tools requires good Fast response performance, accurate and sensitive tracking of the digital command signal issued by the numerical control device, and can faithfully execute the instructions from the precision CNC turning parts numerical control device, improve the system's dynamic following characteristics and static tracking accuracy.

Machine body

The precision CNC turning parts machine tool host is the main body of the CNC machine tool. It includes precision CNC turning parts such as machine bed, base, column, beam, sliding seat, worktable, headstock, feed mechanism, tool post, and automatic tool changer. It is a mechanical part that automatically completes various cutting processes on precision CNC turning parts.
