CNC machining is the process of removing the edge material by pushing the workpiece through the tool rotation. This can change the direction, head speed and pressure on one or more axes.
CNC machining covers a wide range of operations and machines, from small individual parts to large heavy-duty combined milling operations. It is one of the most common processes for machining custom parts to precise tolerances.
Milling can be carried out using a variety of machine tools. The original type of machine used for milling is a milling machine (often called a milling machine).
After the emergence of computer numerical control (CNC) in the 1960s, milling machines gradually developed into CNC machining centers: through automatic tool changers, tool magazines or turntables, CNC functions, cooling systems and casing reinforcement milling machines.
CNC machining centers are usually divided into vertical machining centers (VMC) or horizontal machining centers (HMC).
The number of slave axes of CNC machining center can be divided into three-axis machining center, 4-axis machining center, five-axis machining center and other multi-axis machining centers. The higher the number of axes, the more secondary clamping can be avoided, and the multi-angle machining is easy to cause data deviation. Problem. However, due to the high price and high technical requirements of the 5-axis machining center, most of China's CNC processing plants are mainly 3-axis machining centers.
The parts produced are mainly simple and the data requirements are not strict. Some of the pursuit of high-precision CNC processing plants use imported 5-axis equipment to meet customer needs.
This type of factory often has decades of experience and services in the communications industry, optical industry, medical industry, automotive industry, aerospace industry and other industries with extremely high requirements for components.
