CNC milling processing is one of the more common manufacturing processes. This is mainly due to its high -precision, high accuracy and strict tolerance range. In fact, through CNC milling processing, it can accurately create parts of the same size in small batches, while achieving a tolerance of less than zero and zero. There are many types of CNC machining, with common CNC milling and CNC vehicle.

CNC milling is a processing process, which uses a rotating knife to remove the extra part of the material block until the required custom shape is formed. In addition, CNC milling can process very complex parts while meeting the strict tolerance requirements of the parts. After continuous transformation and improvement of CNC milling, it can create precision parts that meet the strict requirements of today's harsh industries.

CNC milling is mainly used to reduce materials. Fix the parts that need to be milling in the clamping of the CNC workbench, and then process the raw materials through the X, Y, and Z axis of the CNC milling machine, and the cutting material of the main shaft of the tool at a very high speed to achieve the ideal parts.

CNC milling machines have the function of drilling machines and beds. On the multi -batch production line, the use of CNC milling can be used to centralize the processing process, which also reduces the error rate of parts clip while improving production efficiency. In addition, CNC milling also has the function of fast forward, backward, and quickly positioning the blade shelf, thereby reducing maneuvering time.

CNC milling can also process the complex profiles that are difficult to processed by CNC lathes, and even the outline of the plane curve and spatial surface surface of the parts. This is because CNC milling has the characteristics of multiple input and feed axis linkage. Compared with conventional processing, CNC milling has the characteristics of high processing accuracy and complex processing complicated shapes and wide processing scope. According to the characteristics of CNC milling, we can roughly understand that parts suitable for CNC milling mainly include the following types.

1. Parts with complex structures such as curve contour or curved surface: The outline of the plane curve of the part, that is, the part has the inner and outer contour of the complex curve, and the processing surface is parallel or vertically on the horizontal plane. In three -dimensional space coordinates, the surface of the parts is usually a surface change. It is usually designed by mathematical models. During the processing process, the milling cutter always keeps contact with the processing surface. Parts processing curved surfaces are usually used for three -coordinate CNC milling, because programming and processing is required with the help of a CNC system.

2. Ordinary milling that is difficult to process parts: For parts such as size, lines, testing, etc., it is difficult to observe and control parts, because ordinary milling machines do not have a CNC system assisted processing. Therefore, it is very suitable for the processing of these parts to choose a CNC milling machine.

3. Ordinary milling machine does not reach precision and accuracy: Because ordinary milling will have errors caused by human factors, it is difficult to guarantee the size accuracy, shape accuracy and surface roughness of the parts. Therefore, if the accuracy of the part is high, it is necessary to use CNC milling machines for processing.

The basic contour of the complex surface is usually used to process with milling, which initially enables the surrounding CNC machine tools to link three -axis. After entering the 1980s, the five -axis -linked milling machine was widely used in complex surface processing. The outline of the workpiece after milling was very close to the final shape of the workpiece, but the last refined process is still manual operation. In the late 1980s, high -speed cutting technology gradually matured. Its applications in industrial production have been continuously improved in terms of machine tools, tools and other related technologies. Because high -speed cutting can increase the rate of feed feed, it is possible to reduce the spacing of the cutter in without reducing production efficiency, thereby providing prerequisite for improving the shape accuracy of the workpiece and reducing the roughness of the table. At present, most of the workpieces that high -speed milling and processing no longer need the last hand -processed process, but can be directly put into use.

In addition to the characteristics of ordinary milling machine processing, CNC milling processing also has the following characteristics:

1. The parts processing is strong and flexible, and the shape of the outline is particularly complicated or difficult to control the size, such as mold parts, shell parts, etc.;

2. It can process parts that cannot be processed or difficult to process, such as complex curve parts described in mathematical models and three -dimensional space curved parts;

3. After the positioning can be processed at a time, parts that need to be processed by multiple processes;

4. High processing accuracy and stable processing quality. The pulse equivalent of the CNC device is generally 0.001mm, and the high -precision CNC system can reach 0.1 μm. In addition, CNC milling processing also avoids the operation error of the operator;

5. High degree of production automation can reduce the labor intensity of the operator. It is conducive to production management automation;

6. High production efficiency, CNC milling machines generally do not need to use dedicated process equipment such as dedicated fixtures. When replacing workpieces, you only need to call the processing program, fixture tools and adjustment of tool data stored in CNC device. cycle. Secondly, CNC milling machines have the functions of milling machines, beds, and drilling machines, which highly concentrate the process and greatly improve production efficiency. In addition, the main axis speed and feed speed of the CNC milling machine are stepless transmission, so it is conducive to the best cutting amount.

The 5 -axis CNC processing can move the tools and workpieces at the same time, providing a number of advantages for many industries. It can achieve the cost and efficiency and efficient manufacturing of complex parts. The additional rotation during this processing process can achieve more complex design and geometric shapes. This machine can seamlessly process the arc and angle, which can only be achieved through multiple special fixtures before. 5 -axis milling process can rotate parts in one operation to achieve the required geometric shape without complex fixtures. The additional settings involved in manual processing can cause the mechanic to lose accurate accuracy during the manufacturing process. However, the minimum setting involved in the 5 -axis CNC milling reduces the possibility of errors and improves the accuracy required to achieve excellent quality. 5 -axis processing parts are usually completed in one operation because the process has high -speed advantages. The single settings involved help save time and money. In addition, a shorter of a short -term use of a short -term tool, no need to constantly change the tools, saving funds and time.

CNC milling machines are versatile and can be used in a variety of applications. They are particularly effective in creating complex 3D shapes and are commonly used in industries such as automotive, aerospace, and medical. CNC milling machines can work with a wide range of materials, including metals like aluminium and steel, as well as plastics and composites.
