Medical equipment processing not only needs to meet the requirements of high precision and high surface brightness of parts, but also faces the challenge from difficult to process raw materials.
The products of artificial key include hip, knee, shoulder, elbow, wrist, ankle, shin, spine, etc. In the artificial critical processing industry, because it is related to the health and safety of human remains, there are quite high requirements for the processing accuracy, quality and generality.
In the medical industry, the manufacturing enterprises usually have the following requirements for tool suppliers:
1. Partners and joint design strength. The manufacturing enterprises of artificial critical products have a good understanding of the raw materials and design of artificial critical products, but they don’t have much experience in the detailed processing technology of products, so they usually form a strategic partnership with tool suppliers. In the process of new product research and development, the tool supplier enters the joint development, and more researches are made on the stability of processing cost and processing technology, and the controllability of product quality.
2. Quite specific use. The products of artificial critical industries are relatively stable, and the design and use of products are relatively specific. Although the products provided by different companies are different, due to the relatively unchanged human body structure, there will be no significant difference in the products. In this way, the product processing technology and quality assurance system are also relatively similar. This also poses a greater challenge to tool suppliers, constantly improving the quality of tools, improving the level of processing technology, reducing processing costs, and improving the stability and controllability of processing technology.
3. High quality requirements. Most of the artificial critical products need to be implanted into human body, so the raw materials and quality of the products have the highest requirements. In the same way, the same requirements will be put forward for the suppliers including the tool suppliers of the manual critical processing enterprises. In the grinding equipment, the grinding oil temperature, air temperature, tool temperature and grinding point temperature are all detected online. When the temperature is too high or insufficient, the system will automatically adjust the air conditioning system and correct the temperature, so as to maximize the control to ensure the accuracy, quality and generality of the tool and meet the requirements of the medical industry.
4. Product traceability. All artificial critical products have their specific numbers, which are used to track the use of products, so as to achieve the traceability of product quality. If there is a problem with a certain product, it is advisable to trace all batches of the same product and recall the same product. This requirement is certain for the medical industry. Shangao tool has its specific number for tracking. As long as you check the number of this tool, you can immediately track the production date, production equipment, production process, product detection, product transportation and other information of the product.
5. Product certification. Due to the unique use of medical industry, the access threshold for suppliers is also quite high. The supplier must also possess the product certification system to meet the requirements of the medical industry.
The raw materials at the artificial juncture are also improving with the development of the industry. The demand for raw materials meets the requirements of biocompatibility (no adverse effect on human body), bioconversion (the artificial juncture must be integrated with the surrounding tissues), and of course, it also includes the strength and elasticity of raw materials. Moreover, the raw materials required by people of different ages are definitely different, which are suitable for more activities and late hours of young people The recovery of human body and bones in the year of 2000 was slow.
Common raw materials for artificial key include titanium alloy, cobalt chromium alloy (containing cobalt chromium molybdenum alloy), stainless steel, UHMWPE, peek and ceramics, and the heat treatment of raw materials is different, such as forging and forging.
Different raw materials and different heat treatment methods have a huge impact on the machinability of workpiece raw materials. Shangao cutting tool also specially develops a targeted cutting tool and processing plan for different raw materials in the medical industry. For example, when machining titanium alloy, it is advisable to select jhp750 series high efficiency milling tools to remove the surplus in the fastest time. At the same time, this tool can also be used for finishing. For cobalt chromium alloy, jh141 series high-speed milling tools can be selected with unique coating to ensure the surface quality and processing life of the workpiece. Peek raw materials, more and more found in many carbon fiber raw materials are widely used in the artificial critical industries, the selection of a unique custom diamond coated tool greatly improves the efficiency, life and process stability of the tool.
The processing of UHMWPE raw materials, such as the joint surface used in the knee joint, has quite high requirements for the quality of the processed surface, such as RA < 0.20 μ m, and also has different requirements for the workpiece difference target. Seco jabro has developed a special Super meticulous finishing milling cutter, Premier finish, which will be delivered with a unique serial number, product certificate, inspection report, unique tool packaging, etc. for product tracking, and this cutter can also be used for regrinding to reduce processing cost. Customers choose this cutting tool, the efficiency can be increased up to 70%, the process is stable, and the cost of the cutting tool also drops more than 30%.
The medical critical industry is related to human health interest, and the market scale is huge, and the development potential in developing countries is more and more obvious, and it is not affected by the market operation cycle. Most of the overseas key market occupiers still set up branches in China and carry out production. In recent years, the production scale has increased dramatically. Chinese production companies are also trying to catch overseas companies outsourcing a large number of products to China in order to reduce costs
