High-Speed Machining in China
High-speed machining (HSM), is an accelerated process that combines computer numerical control, fast spindles, and ultra-high-speed motion for a specific purpose, such as production runs of parts with complex shapes or highly precise, intricate features. A combination of innovative CNC technology and high-speed spindles feed high-speed tools across the surface of a workpiece at a controlled rate, cutting a wide range of materials with increased accuracy and quality. HSM offers numerous advantages over manual production and traditional machining methods, making it an ideal choice for many applications and industries.
In China, the use of HSM technologies is becoming increasingly popular for a variety of manufacturing applications, ranging from complex shape-designs to intricate details. HSM allows manufacturers to create high-precision parts at a faster rate than traditional machining methods, while eliminating the need for complicated programming routines. This makes it a cost-effective solution for many different types of manufacturing applications. CNC technology contributes to the accuracy and consistency of the finished product; its high speeds can also reduce downtime and produce parts in less time than manual machining.
The adoption of HSM must be preceded by a thorough analysis of the parts being machined and the requirements of the process. High-speed machining requires specific tooling, such as mills and drills, as well as dedicated CNC programming and design capabilities. It also demands a robust environment and the ability to implement preventative maintenance strategies. In addition, certain quality assurance practices must be put in place to ensure the precision and accuracy of the parts.
In China, there is a lack of specific knowledge and access to pre-established supply chains for HSM materials, tools, and machines—thus making HSM more difficult to implement. Moreover, without an experienced machinist conversant with CNC programming abilities, achieving first time accuracy and maintaining consistent high quality can be a challenge. Generally, a well-established set of local suppliers in the area of HSM is often necessary in order to ensure a successful HSM implementation.
The development of the Chinese machining industry is booming, particularly in recent years with the rise of advanced manufacturing technology, highly-trained machinists, and the emergence of more specialized suppliers. The use of HSM is now saving costs, improving production times and yields, and reducing unnecessary wastage, while providing high quality results. However, in order to gain the full benefits of HSM, manufacturers must challenge themselves to overcome any obstacles resulting from lack of knowledge and resources. This can be done through thorough research and training, identifying suitable suppliers and materials, and developing innovative CNC programming techniques to ensure high-precision parts.
High-speed machining has revolutionized the manufacturing industry, and is today being used to create increasingly complex designs and intricate parts in a time-efficient, cost-effective manner. For those companies and businesses located in China wanting to gain the full advantage of this technology, it is imperative to invest in the necessary resources, training and procedures. With the appropriate knowledge, quality assurance procedures, and a secure supply chain for materials and tools, manufacturers can produce high quality parts in a matter of minutes—rather than days or weeks—while ensuring the precision accuracy that is essential to meet and exceed customer demands.
