What is the structural composition of CNC milling machine equipment?

CNC milling machine is a milling machine with electronic meter digital signal control, it is in the general milling machine on the basis of the development of a kind of automatic equipment, the two processes are basically the same, the structure is also somewhat similar. Currently the rapid development of CNC centers, flexible machining units, etc. are in the CNC milling machine, CNC boring machine on the basis of both are inseparable from the milling method. Due to the most complex CNC milling process, the need to solve the most technical problems, the following is a brief introduction to the composition and structure of CNC milling equipment:

A, CNC milling machine is generally composed of CNC system, main drive system, feed servo system, cooling and lubrication system and other major components.

(1) control system CNC milling machine motion control center, the implementation of the CNC program to control the machine tool.

(2) auxiliary devices such as hydraulic, pneumatic, lubrication, cooling system and chip removal, protection and other devices.

(3) spindle box including spindle box and spindle drive system, used to clamp the tool and drive the tool to rotate, the spindle speed range and output torque to have a direct impact.

(4) feed servo system consists of feed motor and feed actuator, according to the programmed feed speed to achieve the relative motion between the tool and the workpiece, including linear feed motion and rotary motion.

(5) Machine tool foundation parts usually refer to the base, column, beam, etc., which is the foundation and frame of the whole machine tool.

The mechanical structure of a typical CNC milling machine is mainly composed of several parts, such as the basic parts, the main transmission system, the feed transmission system, the rotary table and other mechanical function accessories.

Two, the mechanical structure of CNC milling machine

(1) digital control due to effective control of machine tools using servo motors, the application of digital technology to achieve direct control of the machine tool to execute the sequence of the work of the components and the movement displacement.

(2) transmission system of the traditional machine tool gearbox structure is canceled or partially canceled, and thus the mechanical structure is greatly simplified. The digital control system also requires a high degree of transmission rigidity of the mechanical system and no transmission gap to ensure the implementation of control instructions and the realization of the quality of control.

(3) auxiliary system due to the computer level and control capabilities continue to improve, the same machine tool allows more functional components at the same time to perform the various auxiliary functions required has become possible, and thus the mechanical structure of the CNC milling machine than the traditional machine tool has a higher integration of functional requirements.

(4) drive system and traditional machine tools developed on the basis of CNC machine tools, compared with the CNC machine tools, CNC machine tools drive system requires higher precision, drive power faster, the mechanical mechanism of the dynamic \ static, thermal stiffness is better to achieve a long period of continuous operation and as little downtime as possible.

From the requirements of the development of manufacturing technology, along with the emergence of a variety of new materials and new processes, metal cutting is toward the cutting speed and accuracy of more and more high, more and more efficient and the system is more and more reliable in the direction of development.
