Today, I will introduce CNC machining technology to you. CNC machining is a common manufacturing technique that uses computer-controlled machine tools to process parts in modern times. CNC machining service types include milling, turning, drilling, grinding, and wire cutting. Different types are suitable for machining different parts, such as:
CNC Milling is the use of rotating cutting tools to cut workpieces, suitable for machining flat surfaces, grooves, complex surfaces, etc.
CNC Turning is the use of lathes to cut rotating workpieces, suitable for machining cylindrical and conical parts.
CNC Drilling is used to machine precise holes on workpieces.
CNC Grinding is used for high-precision surface machining and dimension correction.
CNC Wire Cutting is the use of electrical discharge cutting technology to process complex shaped parts.
By now, you must have a preliminary understanding of CNC. So, what are the advantages of CNC? Next, let me introduce in detail the advantages of CNC machining parts:
1. High Precision
CNC can process parts with very strict tolerances and is one of the highest precision manufacturing technologies. The error in processing metal or plastic parts is usually in the micrometer level, about 1/4 the width of a human hair, and can almost achieve seamless assembly of parts.
2. Good Repeatability
CNC machining is a digital manufacturing technology that can directly provide high-precision parts from CAD files, and the CNC program can be reused to ensure that each part in mass production has consistent quality and size.
3. High Degree Of Automation
CNC machine tools have different degrees of axis rotation tools, usually three-axis/four axis or five axis. The machining process is fully controlled by computer automation for tool changing, cutting, etc. The high degree of automation in the machining process reduces manual intervention and lowers the risk of human error.
4. High Production Efficiency
Numerical control machine tools can run continuously for 24 hours with fast processing speed. With the cooperation of CNC machining automation flexible production lines, it is possible to achieve multi variety part processing automation intelligent production lines, realize automatic transmission of materials, cutting tools, fixtures, and automated processing. It can achieve unmanned processing and is suitable for small/large batch part production.
5. Strong Ability To Process Complex Parts
CNC machining, under the coordination of multiple axes, controls the equipment through G and M codes to enable the cutting tools to process complex geometric shapes of parts, including three-dimensional surfaces, internal cavities, and other structures that are difficult to achieve through traditional machining, according to the set machining path. At present, high-end seven axis five linkage turning and milling composite machine tools can process various complex parts with high precision.
6. High Flexibility
By simply modifying the machining program, CNC equipment can quickly switch between machining different parts, providing flexible and diverse machining solutions to adapt to multi variety and small batch production.
7. Reduce Material Waste
Numerical control machining reduces material waste and lowers production costs through rational design and optimization of cutting paths.
8. High Security
Operators do not need to have direct contact with the machining process, and can even achieve unmanned operation by monitoring the parts in real-time.
CNC machining is an indispensable machining method in contemporary times and one of the high-end manufacturing industries. If you have parts that need to be processed, CNC technology is a good choice.
