CNC routers in particular have become ubiquitous in Chinese factories. A CNC router is a computer-controlled cutting machine used for milling and drilling operations. CNC routers can accurately cut and shape materials like wood, plastics, metals, foams and composites. They are faster and more precise than manual routing, allowing for high-efficiency production.
The Origins of CNC Technology
CNC technology was first developed in the 1940s and 1950s in the United States. MIT engineer Patrick Hanratty is sometimes credited with inventing the first CNC machine in 1952. Throughout the 1950s and 1960s, CNC machines slowly replaced manually operated machine tools in certain industries like aerospace and automotive in industrialized nations.
However, the adoption of CNC machines across China's manufacturing sector did not take off until the 1980s and 1990s. Starting in the 1980s, China began acquiring CNC technology from abroad, both through legitimate technology transfers and reverse engineering. China's integration into global supply chains also facilitated the influx of CNC machine tools into the country.
Reasons for Widespread Adoption in China
There are several key reasons why CNC routers have been so widely adopted across China's vast manufacturing industries:
- Cost savings - CNC routers can produce components faster and with less waste material compared to manual machining. This boosts productivity and lowers production costs, which is crucial for China's export-oriented factories.
- Consistent quality - CNC routers provide extremely consistent quality because the computer control eliminates variations in human workmanship. Chinese factories can produce higher quality products at scale.
- Flexible production - CNC routers can be quickly programmed and re-programmed to produce different components. This allows Chinese manufacturers to adapt swiftly to changing customer demands.
- Easier training - Operating CNC routers relies more on digital skills than manual machining experience. This makes training new factory workers faster and easier.
- Government promotion - The Chinese government has actively promoted advanced manufacturing technologies like CNC as part of its national industrial policy. Subsidies and tax incentives encourage factory adoption.
Key Chinese CNC Router Manufacturers
Initially, China relied on imported CNC routers from leading foreign brands like Haas Automation and DAEWOO. But over time, domestic Chinese companies have succeeded in manufacturing CNC routers locally. Some of the major Chinese CNC brands today include:
- Weihong - One of China's earliest and largest CNC router manufacturers, founded in 1992 and headquartered in Changzhou. Weihong offers 3, 4 and 5-axis CNC routers for industries like sign-making, metal fabrication, automotive and aerospace.
- Goldenway - Another Changzhou-based company founded in 1998. Goldenway is a global exporter of CNC routers for routing, engraving and machining applications.
- Langzaun - Langzaun is a Shanghai-based company established in 2009 that manufacturers large-format CNC routers for industries like construction, foundry patterns, shipbuilding and transportation.
- Huagong - Based in Changsha, Huagong Technologies is a state-owned company that manufactures affordable CNC systems. Their routers are popular with smaller Chinese workshops.
- Jinan - Founded in 2000, Jinan Bodor CNC Machine Co. designs CNC plasma and oxyfuel cutting systems. Their routers can cut metal sheets up to 25mm thick.
Applications in Chinese Manufacturing
CNC routers are applied extensively across manufacturing in China. Major applications include:
- Furniture production - For milling, drilling and trimming wood products and components. CNC precision allows mass production of affordable furniture.
- Sign making - For precision cutting of plastic, wood, acrylics and composites to produce retail, corporate and public signage.
- Automotive - For cutting body panels, trimming interior upholstery pieces and machining engine components from metals and other materials.
- Aerospace - For machining lightweight aerospace alloys into jet engine and airframe components requiring the highest accuracy.
- Tool, die and mold making - For precision milling of tool steel into injection molds for mass production of plastic goods and die cast molds for metalworking.
- Stone working - For sculpting, drilling, profiling and polishing granite, marbles and other stone materials in applications like decorative stonework, tombstones, kitchen counters.
- Metal fabrication - For cutting, milling and drilling metal stock into components for machinery, automobile parts, artistic metalworking and other fabrication purposes.
The ongoing adoption of advanced CNC routers across China's vast manufacturing industries has boosted productivity and quality. Chinese factories have leveraged this technology to become globally competitive exporters delivering affordable, high-volume production. With China's manufacturing sector still rapidly expanding, demand for locally-built CNC routers is poised for vigorous growth in the years ahead. CNC Milling CNC Machining
