Basic Components Of CNC Machines
Dec 22, 2017

The basic composition of CNC machine includes processing program carrier, numerical control device, servo drive device, machine tool main body and other auxiliary devices.

Process Carrier

The CNC machine tool work, does not need the worker to operate the machine tool directly, must carry on the control to the CNC machine tool, must compile the processing procedure. Parts processing program, including the machine tool and workpiece on the relative trajectory, process parameters (feed spindle speed, etc.) and auxiliary movement.

CNC Device

Numerical control device is the core of CNC machine tool. Modern CNC devices are used in the form of CNC (Computer numerical control), this kind of CNC devices generally use a number of microprocessors, programmed software to achieve the function of the CNC, it is also called software numerical control. CNC System is a position control system, which is based on the input data interpolation to fill out the ideal trajectory, and then output to the implementation of components to process the required parts.

Servo and measurement Feedback system

Servo system is an important part of CNC machine tool to realize servo control and spindle servo control of CNC machine tool. The function of servo system is to accept instruction information from CNC device, and convert it into linear displacement or angular displacement movement of machine tool by power amplification and plastic processing. Because servo system is the last link of CNC machine tool, its performance will directly affect the precision and speed of CNC machine tools and other technical indicators, therefore, the CNC machine tool servo drive, requires a good rapid response performance, accurate and sensitive to trace the digital command signal issued by the CNC device, and can faithfully execute the instructions from the CNC device, The dynamic following characteristics and the static tracking accuracy of the system are improved.

Machine body

Machine tool Mainframe is the main body of CNC machine tool. It comprises a bed, a base, a pillar, a crossbeam, a sliding seat, a worktable, a spindle box, a feeding mechanism, a tool holder and an automatic tool-changing device. It is in the numerical Control machine tool automatically completes each kind of cutting processing mechanical part.

Other auxiliary devices

Auxiliary device is to ensure the full play of CNC machine tools necessary for the function of the supporting devices, commonly used auxiliary devices include: pneumatic, hydraulic equipment, chip device, cooling, lubrication equipment, rotary table and CNC division Head, protection, lighting and other auxiliary devices.
