Basic components of CNC machine
Nov 27, 2017

The basic components of numerical control machine tools include machining program carrier, numerical control device, servo driving device, machine tool body and other auxiliary devices.

Process Carrier

CNC machine tool work, do not need workers directly to operate the machine tool, to control the CNC machine tools, must be prepared processing procedures. In the process of part machining, the relative motion trajectory, process parameters (feed spindle speed, etc.) and auxiliary motion of the tool and workpiece on the machine tool are included. The parts processing program with a certain format and code, stored in a program carrier, such as perforated tape, cassette tape, floppy disk, etc., through the input device of CNC machine tools, the program information input to the CNC unit.

CNC Device

CNC device is the core of CNC machine tools. Modern CNC devices are used in CNC (Computer numerical control) Form, this kind of CNC devices generally use a number of microprocessors, in order to program the software to achieve numerical control functions, it is also known as software NC (Software NC). 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 executive parts to process the required parts. Therefore, the numerical control device mainly consists of three basic parts of input, processing and output. All of this work is properly organized by the computer's system program to make the whole system work in harmony.

Servo and measurement Feedback system

Servo system is an important part of NC machine tool, which is used to realize servo control and spindle servo control of NC machine tool. The function of the servo system is to accept the instruction information from the numerical control device, and after the power amplification, the plastic processing, converts to the linear displacement or angular displacement movement of the machine tool execution parts. Because the servo system is the last link of NC machine tool, its performance will directly affect the precision and speed of CNC machine tools and other technical indicators, therefore, the servo-driven device of CNC machine tools, requires a good rapid response performance, accurate and sensitive tracking the digital control device issued by the numerical instruction signal, and can faithfully carry out the instructions from the NC device, The dynamic following characteristic and the static tracking precision of the system are improved.

Machine body

Machine tool Mainframe is the main body of NC machine tool. It includes the bed body, the base, the column, the Crossbeam, the slide seat, the worktable, the spindle box, the feed mechanism, the turret and the automatic tool-changing device and so on. It is in the CNC machine tools to complete a variety of automatic cutting machine parts.

Auxiliary device of NC machine tool

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