What is a CNC milling machine?
CNC milling machine is an automatic processing equipment developed on the basis of the manual milling machine. The processing technology of the two is basically the same, and the structure is somewhat similar. CNC milling machines are divided into two categories: without tool magazine and with tool magazine. Among them, a CNC milling machine with a tool magazine is also called a CNC machining center.

What is the role of a CNC milling machine?
In addition to the features of manual milling, CNC milling has the following features:
1.The parts processing has strong adaptability and flexibility, and can process parts with particularly complex contour shapes or difficult to control size, such as mold parts, shell parts, etc.;
2.It can process parts that can not be processed or difficult to process by ordinary machine tools, such as complicated curve parts described by mathematical models and three-dimensional space surface parts;
3.It can process parts that need to be processed in multiple processes after one clamping and positioning;
4.The processing accuracy is high, and the processing quality is stable and reliable. The pulse equivalent of the numerical control device is generally 0.001mm, and the high-precision numerical control system can reach 0.1μm. In addition, the numerical control processing also avoids the operating errors of the operator;
5.The high degree of production automation can reduce the labor intensity of the operator. Conducive to the automation of production management;
6.The production efficiency is high. The CNC milling machine generally does not need to use special fixtures and other special process equipment. When replacing the workpiece, it only needs to call the processing program, clamping tool and adjustment tool data stored in the CNC device, thus greatly shortening the production. cycle. Secondly, the CNC milling machine has the functions of a milling machine, a boring machine, and a drilling machine, so that the process is highly concentrated and the production efficiency is greatly improved. In addition, the spindle speed and feed rate of the CNC milling machine are infinitely variable, so it is helpful to choose the best cutting amount.

What is the difference between a CNC milling machine and a manual milling machine?
The processing surface shape of a milling machine is generally composed of straight lines, arcs or other curves. The operator of the manual milling machine constantly changes the relative position between the tool and the workpiece according to the requirements of the drawing, and then matches the selected milling cutter speed to make the tool cut the workpiece, and can process various workpieces of different shapes.
CNC milling machine tool processing is to divide the movement coordinates of the tool and the workpiece into the smallest unit quantity, that is, the smallest displacement. According to the requirements of the workpiece program, the numerical control system makes each coordinate move several minimum displacements, so as to realize the relative movement of the tool and the workpiece to complete the processing of the part.

According to the expansion function, what kinds of CNC milling machines are divided into?
It is divided into a standard three-axis CNC milling machine, a 4-axis CNC milling machine with an optional 4th-axis CNC turntable, and a 5-axis CNC milling machine with an optional 5th-axis CNC turntable.
