CNC milling is a common machinery machining method. CNC milling services are very important in modern manufacturing. This article will detail CNC milling and CNC milling services. It covers all the information on CNC milling characteristics, processing types, advantages, limitations, and applications that you need to understand.
What is CNC milling?
CNC milling is a method of controlling machine tools through a computer program. CNC milling is cut on the workpiece by using a rotating multi-blade tool to remove the shape and characteristics required by the material and create. It is often used to create complex shapes, such as molds, inspection tools, thin-walled complicated curved surfaces, blades, etc.
Characteristics of CNC milling:
1: High accuracy and high repetitiveness
CNC machine tools can determine the accurate location and size of the workpiece by pre-programming so that milling machining has higher accuracy. Moreover, under the guidance of a program, the machine can repeat the same processing operation to ensure that the accuracy of each workpiece is consistent.
2: High efficiency and high automation
Compared with manual milling, CNC milling does not require manual participation in each step. You only need to fix the workpiece and set the program settings to automatically process the machine tool.
3: A variety of processing forms
CNC machine tools can cut in different directions according to the pre-set programs to achieve complex shape machining. In addition, by replacing different tools and fixtures, CNC milling can meet the machining needs of different materials and meet diverse machining requirements.
4: Flexibility and convenience
On CNC machine tools, different machining operations can be performed through simple program modifications. Moreover, the CNC machine tool can monitor the machining process in real-time and adjust it as needed, making the machining process more flexible and convenient.
Types of CNC milling machining:
The types of CNC milling machining mainly include facial milling, standing milling, and imitation milling.
1: Facial milling is the most commonly used milling type for machining planes. Facial milling cutters are often installed on the main axis and used to process parallel planes with knives. Facial milling can complete the machining of the workpiece at one time, or you can use the milling cutter that requires several strokes to complete the workpiece machining.
2: Standing milling is mainly used for machining of about 90 degrees, similar to facial milling, but the angle of the round cutting blade has a decisive role. The side of the knife of the standing and milling is parallel to the axis of the rotation, which is suitable for a 90-degree convex shoulder.
3: Imitation milling is used for machining free surfaces (such as the curved surface). This is a special milling method that is suitable for machining workpieces with complex curved surfaces.
These types of milling machining methods can be selected according to the specific needs and geometry of the workpiece to achieve efficient and accurate machining.
Advantages and limitations of CNC milling machining:
Advantages:
1: Complex geometric shapes: can produce a variety of complex shapes, including grooves, holes, and complex outlines.
2: Multi-axis machining: Modern CNC milling machines can move along multiple axes, carry out three-dimensional processing, and make fine parts.
3: Flexibility: It is suitable for both small and large-scale production, but also for prototype production.
4: Diverse tools: A variety of cutting tools and tool paths can be used, which is suitable for different machining operations.
Limitations:
1: Complex settings: Compared with turning, more complicated fixtures and settings are needed, which will increase the preparation time and cost.
2: High cost: Generally, milling machines and related tools are more expensive than lathes.
3: Surface smoothness: Compared with the turning, the fine surface smoothness is more challenging, especially on the plane.
4: Duration of tools: The multi-point cutting tool used during milling is worn quickly, especially when machining hard materials, so you need to change the tool frequently.
Application of CNC milling
CNC milling has the advantages of efficiency, accuracy, and flexibility, and it is widely used in the fields of mechanical manufacturing, aerospace, automotive, medical, electronics, new energy, and other fields.
Mechanical manufacturing parts: such as bearing seats, flanges, gears, key grooves, etc.
Aerospace: aircraft parts, structural components, engine components, and other special parts with strict tolerances and quality standards.
Automotive industry: engine components, chassis components, gearboxes, internal and external decoration components, etc.
Medical industry: surgical equipment and implants, orthopedic equipment, dental tools, and other functional components with strict safety and quality specifications.
Electronic: electronic shell, radiator, etc.
New energy: generator parts, turbine, solar panel components, etc.
Conclusion
CNC milling is a precision machining method. Through CNC machine tools and computer control systems independent of artificial operation, high-precision machining of the shape and surface accuracy of the workpiece is realized. CNC milling has occupied an indispensable position in the manufacturing industry.
