With the continuous progress of society and technological innovation, precision CNC machine tools are more and more widely used in the medical field. The parts of medical device have the characteristics of complex structure, tough material and difficult processing. Medical precision parts processing, are directly used for finished products, so the appearance requirements are very high, must have more professional processing technology to achieve.
This blog of Longsheng technology website will introduce in detail the difficulties and solutions of cnc processing of medical devices
The difficulties and solutions of medical CNC Machining
Deal with difficult structures
In the design process of some medical devices, there will be difficult processing structures, which will increase the difficulty of processing and the complexity of the produced equipment. However, CNC machining equipment is often difficult to handle such complex material structure.
solution
We need to adapt machining strategies and use special mechanical and software tools, such as numerical control systems, to process complex material structures. At the same time, we need to optimize the processing steps, such as step processing and so on.
High precision of medical equipment requirements
Medical instrument is a kind of product related to human life and health, so it requires very high precision in the process of processing. However, there will be many factors in online CNC machining affecting machining accuracy, such as mechanical wear, machining errors, material deformation and so on. Therefore, how to ensure the precision of medical device processing has become a very key link in the process of medical device manufacturing.
solution
First of all, in the material selection, we should optimize the material selection according to processing requirements and material properties and other factors. Secondly, processing precision can be effectively improved by improving processing quality, such as improving machine tool wear and improving tool life. In addition, the selection of appropriate processing technology, carefully formulated processing process, can also greatly improve the processing accuracy.
Surface treatment of medical instruments is difficult
In order to ensure the safety and corrosion resistance of the surface of medical devices, surface treatment is also an important work in the manufacturing process of medical devices. However, cnc machining surface treatment of medical equipment is also very difficult. For example, due to processing residual oil, dust and so on, resulting in uneven surface oxidation and so on.
solution
Compared with the traditional surface treatment method, the environment-friendly chemical surface treatment technology is a new solution for the surface treatment of medical devices. It can quickly clean and modify the surface without changing the surface shape, and enhance the surface lubricity and corrosion resistance. In addition, in the process of using CNC machining, you can carefully clean the machine surface and replace the cutting fluid before machining to reduce the residual problem on the machined surface.
Material selection
The first thing we need to consider is the right material selection. In CNC processing of medical devices, we often use some special materials, such as stainless steel, titanium alloy, medical plastics and so on. These materials have special viscosity and corrosion resistance, but it is difficult to accurately process in CNC processing. Therefore, we need to combine the properties of the material to choose the best manufacturing method.
solution
When selecting materials, we can consider some known processing methods, such as cutting processing, stamping processing, 3D printing and so on. These methods can choose the best production mode according to the actual situation.
High safety requirements for medical devices
The safety of medical device is one of the key points in the manufacture of medical device. In the process of cnc machining of medical device, how to ensure the safety of medical device manufacturing is also the focus of manufacturers. In the manufacturing process of medical devices, it is necessary to ensure product quality and strictly control the production process to reduce the chance of errors.
solution
We can use quality management to ensure the safety of medical device manufacturing. For example, strict inspection of materials in the manufacturing process, the selection of high quality materials, to ensure product quality. Meanwhile, anSPC production process control and quality inspection mechanism are established to ensure the stability of quality control through real-time monitoring and feedback mechanism.
Precision control
The precision of CNC machining is very important in the production of medical devices. Very small errors can affect the effectiveness and safety of medical devices. However, in the manufacturing and assembly process, there will be a variety of factors, such as temperature changes, tool wear and so on, will affect the accuracy of CNC machining.
solution
We need to confirm the best CNC machining scheme to ensure that the final output of the equipment is of high quality and precision. This requires us to allocate all kinds of production resources scientifically, set reasonable cutting parameters and complex physical models to ensure the machining accuracy. In addition, we can improve the quality of mold production, such as reducing tool wear, so that we can better control CNC machining.
CNC machining of medical devices is a highly accurate production process. When dealing with materials and structures, we need to use special techniques and tools to overcome these difficulties. This manufacturing method brings significant advantages to the manufacturing process of medical devices and medical devices, which can greatly improve their function and quality, while also improving the reliability and safety of specialized medical devices.
