What is CNC milling

Milling is a metal cutting process that is completed by moving the rotating tool and workpiece into the spindle. Milling can be on the workpiece plane processing, groove processing, tapping, drilling, reaming, boring, chamfering, and gear processing.

CNC milling features

CNC milling processing in addition to the characteristics of ordinary milling machine processing, there are the following characteristics:


It has strong adaptability and flexibility for parts processing and can process parts with complicated contour shapes or difficult-to-control dimensions, such as mold parts, shell parts, etc.


Can process ordinary machine tools can not process or are difficult to process parts, such as complex curve parts described by mathematical models and three-dimensional space surface parts.


Can process a clamping positioning, the need for multi-process processing of parts, such as in horizontal milling machine can be easily on the box parts for drilling, reaming, reaming, boring, tapping thread, milling end face, groove, and other multi-process processing.


High processing precision, stable and reliable processing quality.


The production automation process is high and can reduce the operator's labor intensity. Conducive to production management automation.


High production efficiency. Generally, it can eliminate the work of marking and intermediate inspection and can eliminate the complex tooling, and reduce the installation and adjustment of parts. It can effectively reduce the auxiliary time in machining and improve production efficiency by selecting the best process line and cutting amount.


From the cutting principle, both end milling and milling are discontinuous cutting modes, not like turning as continuous cutting, so the requirements of the tool are higher, with good impact resistance, toughness, and wear resistance. In dry cutting conditions, also requires good red hardness.

CNC milling machining parts

Compared with conventional machining, NC milling has the characteristics of high machining accuracy, machining of complex shape parts, and a wide machining range. According to the characteristics of CNC milling, we can roughly understand that suitable 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 a 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 choosing CNC milling machine processing is very suitable

3, an 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 with higher precision requirements, need to use CNC milling machine processing.
