Introduction: CNC machining is one of the most common manufacturing technologies. This is mainly due to its high accuracy, precision and strict tolerance range. In fact, with CNC machining, parts of the same size can be accurately manufactured in small batches while achieving tolerances as small as a few tenths of a millimeter. There are many types of CNC machining, CNC milling and CNC turning are common. This paper will mainly introduce the characteristics of CNC milling and suitable for CNC milling parts.
CNC milling is a process in which a rotating tool is used to remove excess parts of a material block until the desired custom shape is formed. In addition, CNC milling can meet the strict tolerance requirements of parts, while machining very complex parts. CNC milling through continuous transformation and improvement, can be produced to meet the stringent requirements of today's harsh industry precision parts.
CNC milling is mainly used for material reduction manufacturing. The parts that need to be milling are fixed in the CNC workbench fixture, and then the raw materials are processed through the X, Y and Z axes of the CNC milling machine, and the material is cut by rotating the tool spindle at a very high speed, so as to achieve the ideal parts.
CNC milling features
The application of CNC milling has the characteristics of flexibility and diversity, its application in a variety of different structures and complex shape parts processing, CNC milling machine can complete drilling, boring, milling plane, milling end face, tapping and other processes. In addition, CNC milling has high precision and high repetition accuracy, which can meet the requirements of high quality machining. CNC milling effectively avoids the error of personnel operation and effectively maintains the consistency of the size of parts in small batch processing.
CNC milling features
CNC milling machine has the functions of drilling machine and boring machine. In the production line of many varieties and small batch, the use of NUMERICAL control milling makes the processing process centralized, which improves the production efficiency and reduces the error rate of parts clamping. In addition, CNC milling has the function of fast forward and backward as well as fast positioning tool rest, thus reducing maneuvering time.
CNC milling can also process complex profiles that are difficult to be processed by CNC lathes, and even plane curve profiles and spatial surface profiles of parts. This is because CNC milling has multiple feed coordinates and feed shaft linkage characteristics.
Which parts are suitable for CNC milling
Compared with conventional machining, NC milling has the characteristics of high machining accuracy, machining of complex shape parts and wide machining range. According to the characteristics of CNC milling, we can roughly understand that suitable for CNC milling parts mainly include the following types.
1, curve contour or surface of complex structure parts: parts of the plane curve contour, that is, parts with internal and external contour for complex curve, processing surface parallel or perpendicular to the horizontal plane. In three dimensional coordinates, the surface of a part is usually a variation of points on the surface. It is usually designed by mathematical models. In the process of machining, the cutter and the machined surface always maintain point contact. 3 - axis CNC milling is usually used for machining surfaces of parts, because it is necessary to program machining with the help of CNC system.
2, ordinary milling difficult to process parts structure: for the size, marking, detection and other difficult to observe and control parts, because the ordinary milling machine without CNC system auxiliary processing. So for these parts choose CNC milling machine processing is very suitable.

3, ordinary milling machine can not achieve precision and accuracy: due to ordinary milling will exist human factors caused by the error, it is difficult to ensure the size accuracy, shape accuracy and surface roughness of parts. Therefore, for parts of higher precision requirements, need to use CNC milling machine processing.
This article mainly introduces the characteristics of CNC milling, reading the full text can understand the application of CNC milling with flexible and diverse characteristics, its application in a variety of different structures and complex shape parts processing, CNC milling machine can complete drilling, boring, milling plane, milling end face, tapping and other processes. In addition, the paper also introduces the application of CNC milling to the machining of complex structures such as curves, contours or surfaces and parts that are difficult to be processed by ordinary milling machines.
