The quality of these products and parts directly impacts patient life and health. This article primarily discusses the impact and advantages of precision machining equipment incorporating digital technology in the manufacturing of related products and parts for the medical industry.
Basic concepts, principles and future development of digital CNC machining technology
The Basic Concepts of Numerical Control Machining Technology: Numerical Control (NC) machining technology is one of the core technologies in modern manufacturing. It relies on digital information and computer technology to achieve automated and precise control of the machining process. This technology, through pre-programming, converts the dimensions, shape, and machining process parameters of the workpiece into computer-recognizable digital instructions. These instructions are then received and executed by the CNC machine tool, driving the tool and workpiece to move relative to each other along a predetermined trajectory, thereby completing the high-precision machining of complex-shaped parts. CNC machining technology integrates knowledge from multiple disciplines such as mechanics, electronics, computer science, and automatic control, and has significant advantages such as high machining accuracy, high production efficiency, good machining flexibility, and low labor intensity. It can not only meet the diverse needs of single-piece and small-batch production but is also suitable for large-scale customized production, making it an important force driving the manufacturing industry towards intelligence and precision. With the continuous advancement of intelligent technologies, CNC machining technology is developing towards higher precision, faster speed, and greater intelligence.
Classification, Principles and Impacts of Digital Control Systems for Precision CNC Machining Equipment
The control system of digital CNC machining technology is one of the key factors determining its performance and application range, directly affecting the machining accuracy, efficiency, and stability of the machine tool. CNC machining technology can be mainly classified into open-loop control systems, closed-loop control systems, and semi-closed-loop control systems. An open-loop control system is a relatively simple and low-cost CNC system. In this system, the command signals issued by the CNC device directly control the operation of the servo motor, without a feedback loop to detect the actual motion state of the machine tool. Therefore, its control accuracy is mainly affected by mechanical transmission errors, servo motor performance, and environmental factors. Due to the lack of a feedback mechanism, the open-loop control system cannot automatically adjust the control signal to eliminate errors, so its machining accuracy is relatively low. It is suitable for applications with low precision requirements, such as some simple CNC lathes and CNC milling machines. A closed-loop control system, on the other hand, achieves precise control of the machine tool’s motion state through a feedback mechanism. In this system, sensors installed on high-precision measuring devices (such as linear scales and inductive synchronizers) can monitor the actual motion state of the machine tool in real time and feed back the detected signals to the CNC device. The CNC device compares the feedback signal with the command signal, calculates the error value, and automatically adjusts the control signal according to the error value to eliminate the error and achieve high-precision machining.
Closed-loop control systems offer advantages such as high control precision and strong anti-interference capabilities, but their complex structure, high cost, and stringent requirements for the accuracy and stability of the measuring device are significant drawbacks. Semi-closed-loop control systems fall between open-loop and closed-loop systems. They indirectly reflect the machine tool’s motion state by detecting the rotation angle of the servo motor or lead screw, feeding the detected signal back to the CNC unit. The CNC unit adjusts the control signal based on the feedback signal to reduce errors. Because semi-closed-loop control systems do not directly detect the actual position of the machine tool’s table or tool, their control precision is slightly lower than that of closed-loop control systems. However, their system structure is relatively simple, their cost is lower, and their requirements for the measuring device are relatively lower. Semi-closed-loop control systems are currently the most widely used type of control system in CNC machining, capable of meeting the machining needs of most CNC machine tools.
The core of CNC machining equipment is the control system. Through CNC optimization, the control system can make the equipment more intelligent, thereby producing more precise parts, meeting the market demand for medical products and equipment, and meeting the need for efficient patient treatment.
Types of medical parts that can be manufactured by digital mechanical machining equipment
Medical components are mostly characterized by small batches, diverse varieties, irregular shapes, hard materials, and high surface finish. These components require rigorous milling, turning, and drilling processes, such as orthopedic implants (bone plates, artificial joints, bone screws, etc.), dental implants, and pacemaker components.
Medical device tools are renowned for their complex structures and high precision and reliability requirements. The increasingly stringent requirements for workpiece materials, machining accuracy, and surface finish in medical device parts necessitate a further advancement in precision machining capabilities. Digital precision machining technology is an advanced manufacturing technology developed to adapt to modern high-tech advancements. In recent years, with the rapid development of global intelligent technologies and related manufacturing technologies, precision machining technology will contribute increasingly more to the medical device industry. Furthermore, as the medical device industry develops and global demand for healthcare increases, companies will develop a wider variety of medical devices with more complex structures and higher precision requirements. This will accelerate the development of machining technologies and related equipment towards higher precision, intelligence, integration, and environmentally friendly precision machining, placing higher demands on machine tools, fixtures, software, testing equipment, and engineering design capabilities.
Why are precision medical components manufactured using digital machining technology?
Medical components range from small parts like buttons and switches to larger components such as display housings. They also encompass surgical instruments and artificial joints, as well as parts for medical pumps, CT scanners, and MRI scanners. CNC machining offers an excellent method for producing precision medical components. For reasons of human safety, non-toxicity, and ease of sterilization, medical institutions typically choose safe, durable, and rust- and wear-resistant materials. For example, joint replacement components are often made of medical-grade stainless steel or medical-grade titanium to achieve high strength, support, and elasticity.
When medical product R&D companies require precision parts, CNC precision machining companies use digital equipment to manufacture these special materials into precision parts of complex shapes and sizes that meet the requirements, based on customer drawings and actual needs. Some of these parts may even be implanted inside the human body, so these workpieces must meet extremely stringent precision requirements, and the workpiece surface must be extremely smooth, burr-free, and streak-free.
Furthermore, digital CNC machining boasts a detailed manufacturing process, various processing techniques and methods, enabling even extremely hard materials to be transformed into smooth machines that meet specific requirements. It can even design precisely fitted parts based on blueprints and assemble them into a large, targeted machine to achieve optimal performance.
The main challenge of digital machining equipment is that medical devices need to be miniaturized to meet their safety and comfort requirements, because only sufficiently small and precise components can be implanted into the human body so that patients who need medical devices such as insulin pumps, heart monitors and defibrillators can lead a relatively normal life.
Finally, CNC precision machining equipment combined with digital technology can also enable the customized design of certain medical device components to achieve precise and personalized fits. This is especially important for artificial devices that need to precisely adapt to people’s needs, such as artificial knees and prostheses.
