With the rapid development of China's economy in recent years and the acceleration of the aging process of the population, domestic medical devices have also ushered in rapid development, especially in the wave of domestic substitution, Chinese medical device companies are developing rapidly, In the new wave of world economic integration, it is the general trend to accelerate the transfer of global manufacturing to mainland China, and China will gradually develop into a world-class manufacturing base. Chinese enterprises have also made great progress in precision parts manufacturing technology, and a large part of medical equipment has achieved independent control. It can be said that the application of high-precision precision parts manufacturing technology will bring new developments to the development of China's medical device industry. opportunities and changes.

The application of precision cutting tools in the medical device industry, the production of special materials, complex-shaped workpieces and small batches of medical parts have put forward new requirements for the selection and use of cutting tools in medical device processing.

Requirements for the selection and use of precision tools in the medical device industry

        1. Precision requirements

        Tolerances in the micron range are common in the medical industry, and selecting the correct tool requires insight and experience. On the one hand, even drilling small holes requires the use of lubricants to reduce friction, reliably dissipate heat and dispose of fine iron filings at the cutting edge; cutting tools for high-quality surfaces.

2. Cost control

      Experienced processing masters will choose the appropriate profile to process parts according to the drawings. This will not only speed up the cutting amount during the processing of parts, but also reduce the cost of materials. This will not only reduce the production cost of a single part, It can also reduce the consumption of tools.

Difficulties in the processing of special material parts for medical devices

        1. Difficult-to-machine titanium alloy materials

        The vast majority of medical device implant parts are made of Ti6AI-4V titanium alloy, which is derived from light weight, good biocompatibility, excellent fatigue strength and low modulus, and is suitable for corrosion resistance and high toughness. Use environment, it is preferred. Titanium alloy 6Al-4V has become the most commonly used material for medical implant devices.

Titanium alloy has the characteristics of work hardening, the shearing process is relatively large, the chips produced are thin, and a relatively small contact area is formed on the tool. In addition, the high cutting force during the process, combined with the friction force when the chips flow, will comprehensively Cause the local cutting heat of the tool to be too high. The thermal conductivity of titanium alloy is poor, so that the cutting heat cannot be conducted quickly. At this time, it is necessary to use cutting fluid to assist in cooling during the processing to ensure that the material properties of the workpiece do not change.

        2. Reliable machine tool fixture

        Small medical parts that are complex and require high precision, such as bone and joint replacement parts, are quite complicated; due to the poor cutting performance of the processed materials, the blank is usually a bar, which means that a large amount of metal needs to be cut. Medical device parts and components have high requirements for workpiece materials, machining accuracy, and smooth surface, which means that the processing parts have higher requirements for machine tools, fixtures, tools, CAM software, etc. The high-end processing equipment group can not only guarantee the quality of the processed parts The quality, but also to ensure product delivery

        3. Stable and efficient tool

Completely different from ordinary machining centers and lathes, precision medical processing machine tools are very small in size and compact in structure; to meet such requirements, the structure of the tool also needs to have a special design, requiring the size of the tool to be small, and at the same time Ensure the rigidity of the tool.

As far as the workpiece itself is concerned, it is very different from other mechanical parts; medical devices implanted in the human body must first have a very good finish, high precision, and no deviation. Insert coating applications are subject to high machining requirements.
