The Introduction of CNC Milling Machine

CNC Milling Definition

The development of science and technology and the rise and continuous maturity of advanced manufacturing technology in the world have put forward higher requirements on CNC machining technology; the application of ultra-high-speed cutting, ultra-precision machining, and other technologies, and the CNC system, servo performance, and spindle drive of CNC machine tools, Machine tool structure, etc. put forward higher performance indicators; the rapid development of FMS and the continuous maturity of CIMS will put forward higher requirements on the reliability, communication functions, artificial intelligence and adaptive control of CNC machine tools. With the development of microelectronics and computer technology, the performance of numerical control systems has become increasingly perfect, and the application areas of numerical control technology have been expanding.


CNC milling machines refer to computer numerical controlled (CNC) milling, it is milling process which takes place on CNC milling machine. And CNC milling machine is the ordinary milling machine integrated with a numerical control system, which can be used to perform more precision milling under the control of program code. During CNC milling, the cutter is able to move along multiple axis, and can create a variety of shapes, slots, and holes, which were previously unattainable through the traditional manual milling process. In addition, the workpiece is often moved across the milling tool in different directions, unlike the single axis motion of a drill.


The Development of CNC Machine Tool

With the rapid development of social production and science and technology, mechanical products are becoming more sophisticated and complex, and the requirements are frequently modified, especially for mechanical parts required in aerospace, shipbuilding, military and other fields, which require high precision, complex shapes, and small batches. Processing such products requires frequent modification or adjustment of equipment. Ordinary machine tools or highly specialized automated machine tools cannot meet these requirements. In order to solve the above problems, a new type of machine tool-CNC machine tools came into being. This new machine tool has the advantages of strong adaptability, high processing accuracy, stable processing quality, and high production efficiency. It is a comprehensive application of electronic computers, automatic control, servo drive, precision measurement, and new mechanical structure. It is the development direction of CNC machine tools in the future.


Main Parts of CNC Milling Machine

1.Base: the base for the overall structure, the base, the main objective is to support the workbench, the weight of the slider. In addition to cutting fluid is in here.

2.Column: the main purpose, is to support the spindle box slide up and down.

3.Spindle box: the spindle box is the heart of the machine tool, the main purpose of rotation speed, automatic feeding, drilling, tapping.

4.The slider: the main purpose, to complete the X, Y to conversion.

5.Table: the main purpose, the clamping workpiece, complete the whole process.


CNC Milling Application

CNC milling mainly includes plane milling and contour milling, it is mainly used for processing a variety of complex plane, curve surfaces and shell parts, such as various types of cam, mold, connecting rod, blade, propeller, box parts, etc. And CNC milling is mainly suitable for machining the following parts:

1.Parts with a plane surface.

2.Parts with straight line curved surface.

3.Parts with stereoscopic surface.


How Does CNC Milling Work?

CNC milling process is not that different from traditional milling, it also involves the cutting tool, spindle, chuck, the only thing different is that there is a computer interface equipped with CNC milling machine. The function of each portion is as below:

Spindle: Rotates the chuck across multiple axes.

Chuck: Locks your material in place for machining.

Interface: Reads computer-aided design (CAD) or computer-aided manufacturing (CAM) files and controls the milling machine with operator input.


Advantages of CNC Milling
