1. Introduction to CNC Machining

(1) Definition of CNC Machining

(2) Advantages of CNC Machining

1. High Precision
   • CNC Machining can achieve extremely high processing precision, usually reaching ±0.001 inches or even higher. This is crucial for medical accessories that have extremely high precision requirements. For example, when manufacturing some precision surgical instrument accessories, only high-precision processing can ensure the accuracy and safety of the accessories during surgery.
2. High Efficiency
   • Compared with traditional processing methods, CNC Machining can greatly shorten the processing time. It can realize automated processing without frequent human intervention, thus improving production efficiency. Taking a European and American medical equipment manufacturing enterprise as an example, after introducing CNC Machining technology, the production efficiency of its medical accessories has increased by about 30%.
3. High Flexibility
   • CNC Machining can easily realize the processing of parts with different shapes and sizes by modifying the program. For the diverse product requirements of medical accessories, this flexibility can meet various special design requirements.

2. Application of CNC Machining in Medical Accessory Bending Equipment

(1) Application in Equipment Structure Design

1. Frame Processing
   • The frame of the medical accessory bending equipment needs to have high strength and high precision characteristics. Through CNC Machining, the various components of the frame can be precisely processed to ensure its dimensional accuracy and surface quality. For example, when processing the mounting holes of the frame, CNC Machining can ensure that the position accuracy of the holes is within ±0.01 mm, thus providing a good foundation for subsequent assembly.
2. Bending Component Processing
   • The bending component is the core part of the equipment, and its precision directly affects the bending angle precision of the medical accessory. CNC Machining can process bending dies and fixtures with various shapes and precision requirements. For example, when processing a bending die with a complex shape, CNC Machining can gradually process the shape of the die by layered milling, and can ensure that the surface roughness of the die reaches Ra0.8 or less, meeting the requirements of high-quality bending of medical accessories.

(2) Application in Processing Technology

1. Angle Adjustment Technology
   • During the bending process of medical accessories, it is necessary to precisely adjust the bending angle. CNC Machining technology can precisely control the bending angle by controlling the movement trajectory of the cutting tool and processing parameters. For example, by adjusting the feed rate and cutting depth of the cutting tool, the bending angle can be precisely adjusted within ±0.1°.
2. Bending Technology
   • In the actual bending operation, CNC Machining can ensure the stability and consistency of the bending process. It can automatically adjust the bending force and bending speed according to different medical accessory materials and thicknesses. For example, for some thinner medical stainless steel sheets, CNC Machining can adopt a lower bending force and a slower bending speed to avoid cracks or deformation of the material.

3. The Improvement of Medical Accessory Quality by CNC Machining

(1) Improving Precision and Consistency

1. Dimensional Precision
   • The medical accessories processed by CNC Machining can greatly improve their dimensional precision. For example, when processing some small medical accessories, such as the connectors of medical needles, the dimensional deviation can be controlled within ±0.005 mm, ensuring the precise fit of the accessories with other components.
2. Shape Precision
   • For some medical accessories with complex shapes, CNC Machining can ensure their shape precision. For example, when processing some medical catheter accessories with curved shapes, CNC Machining can control the shape of the accessories to be highly consistent with the design requirements through precise tool path control, with an error not exceeding ±0.05 mm.

(2) Improving Material Properties

1. Surface Quality
   • CNC Machining can improve the surface quality of medical accessories by optimizing processing parameters. For example, when processing the surface of some medical accessories that need to be in contact with the human body, fine cutting parameters can be used to make the surface roughness reach Ra0.2 or less, reducing the irritation to human tissues.
2. Internal Stress Control
   • During the processing process, CNC Machining can effectively control the internal stress of the material through reasonable cutting order and tool path planning. For example, when processing some large medical equipment shell accessories, through reasonable process arrangement, the internal stress can be controlled at a low level, avoiding deformation or cracking of the accessories during use.

4. The Development Prospect of CNC Machining in the Medical Accessory Manufacturing Industry

(1) Technological Innovation Trends

1. Intelligent Processing
   • In the future, CNC Machining technology will develop in an intelligent direction. By introducing artificial intelligence and machine learning algorithms, machine tools can automatically learn and optimize processing parameters, improving processing efficiency and quality. For example, machine tools can automatically select the best cutting tools and cutting parameters according to the material characteristics and processing requirements of medical accessories.
2. Multi-axis Processing Technology
   • Multi-axis CNC Machining technology will be more widely used. It can realize the processing of medical accessories with more complex shapes and increase the design freedom of products. For example, 5-axis CNC Machining can complete the processing of multiple surfaces of medical accessories in one clamping, reducing the number of clamping times and improving processing precision.

(2) Market Demand Growth

1. The Development of the Medical Industry
   • With the aging of the global population and the increasing attention to health, the medical industry will continue to develop rapidly. This will drive the continuous growth of the market demand for medical accessories, providing a broad market space for the application of CNC Machining technology in the medical accessory manufacturing industry.
2. Personalized Medical Needs
   • Personalized medicine is an important development trend in the future medical industry. The personalized needs of patients for medical accessories will be higher and higher, which requires medical accessory manufacturing enterprises to be able to quickly respond to market needs and provide customized products. The high flexibility of CNC Machining technology enables it to well meet the manufacturing needs of personalized medical accessories.
