Numerical control (NC) technology is a system that uses digital signals to manage and regulate the movement and operation of machinery. NC equipment represents a modern mechatronic product, formed by integrating advanced technologies like numerical control into traditional and emerging manufacturing sectors—essentially, it's a form of digital machinery. The field of NC technology spans multiple disciplines, including mechanical manufacturing, information processing and transmission, automatic control, servo drive systems, sensor technology, and software development.
The evolution of numerical control technology has not only transformed traditional manufacturing but also become a symbol of industrial advancement. As this technology continues to evolve and expand into new areas, it plays a crucial role in key industries such as IT, automotive, light industry, and healthcare. These sectors increasingly rely on digitized equipment, which is now a major trend in modern development. Looking at global trends in CNC technology and its equipment, several research hotspots have emerged [1-4].
One significant trend is the advancement in high-speed and high-precision machining technologies and equipment. Efficiency and quality are central to modern manufacturing. High-speed and high-precision machining significantly boosts productivity, enhances product quality, shortens production cycles, and strengthens market competitiveness. This area has been recognized as one of the top five modern manufacturing technologies by the Japan Advanced Technology Research Association, and the International Society of Production Engineering (CIRP) has identified it as a core research focus for the 21st century.
In the automotive industry, for example, the production cycle for 300,000 units per year is just 40 seconds per vehicle, making multi-variety processing a critical challenge. In aerospace, parts often feature thin walls and ribs with low rigidity, typically made from aluminum or aluminum alloys. These components require careful control of cutting speed and force to avoid damage. Recently, large-scale aluminum alloy blanks have been used to produce complex parts like aircraft wings and fuselages, replacing numerous rivets and screws. This approach improves strength, rigidity, and reliability, all of which demand high-speed, high-precision, and flexible machining tools.
At EMO2001, high-speed machining centers were already achieving feed rates of up to 80 m/min and rapid traverse speeds of around 100 m/min. Many global automobile manufacturers, including China’s Shanghai General Motors, have transitioned from conventional machine tools to high-speed machining centers. For instance, the CINCINNATI HyperMach machine offers a feed rate of 60 m/min, a rapid traverse speed of 100 m/min, an acceleration of 2g, and a spindle speed of 60,000 rpm. It can complete a thin-walled aircraft part in just 30 minutes, compared to 3 hours for a standard high-speed mill and 8 hours for a regular milling machine. Meanwhile, the German DMG double-spindle lathe features a spindle speed of 12,000 rpm and an acceleration of 1g.
In terms of precision, over the past decade, the accuracy of standard CNC machines has improved from 10 micrometers to 5 micrometers, while precision machining centers have moved from 3–5 micrometers to 1–1.5 micrometers. Ultra-precision machining is now reaching the nanometer level, with accuracies as fine as 0.01 micrometers. This continuous improvement underscores the growing importance of NC technology in driving innovation across various industries.
Wear parts are essential components in various industrial machines and equipment that experience regular wear and tear during operation. These parts are designed to withstand the harsh conditions of industrial applications and are crucial for maintaining the efficiency and longevity of the machinery.
Wear parts are commonly used in industries such as mining, construction, agriculture, and manufacturing. They include components such as cutting edges, teeth, blades, and buckets for heavy machinery, as well as grinding media, liners, and hammers for crushing and grinding equipment. These parts are typically made from high-strength materials such as steel, alloy steel, and tungsten carbide to ensure durability and resistance to abrasion, impact, and corrosion.
The performance of wear parts directly impacts the productivity and operating costs of industrial equipment. Worn-out or damaged wear parts can lead to decreased efficiency, increased downtime, and higher maintenance and replacement costs. Therefore, it is crucial for industries to invest in high-quality wear parts and regularly inspect and replace them to ensure optimal performance and safety.
In conclusion, wear parts play a vital role in the operation of industrial machinery and equipment. By using high-quality wear parts and implementing proper maintenance and replacement practices, industries can maximize the efficiency and lifespan of their equipment, ultimately leading to improved productivity and cost savings.
