CNC machining in China

Machining includes manual machining and CNC (computer numerical control) machining.  Manual processing means that people use their hands to control the foam or lathes, milling machines, drilling machines, grinding machines, tapping tools and sawing machines, etc., so that the processing work can be achieved.  Suitable for simple and small batch production.  CNC machining is a process in which mechanics use a wide range of computer-aided machines to complete various machining tasks.  The equipment mainly includes CNC milling machine or CNC machining center, CNC lathe or CNC lathe, CNC grinder and so on.  Today, most machine shops are equipped with CNC or computer numerical control machines and technology.  

A CNC machine converts the position of the workpiece on the X, Y, and Z axes into programming language by programming in the G code language and some software.  Then, the controller of the CNC machine guide the axis of the machine through the code language, so that the workpiece is shaped into a certain shape.  Precision machined parts are then obtained.  CNC machining is suitable for mass production and complex mechanical parts.  

CNC machines have many advantages over manual machining, and they create many advantages in the first place. They can run faster and save a lot of time.  CNC machines can produce sound parts in minutes or even seconds, whereas skilled mechanics or artisans would normally spend hours making parts on manual machines.  Because parts or components manufactured by CNC machines can run more efficiently and require less labor, parts or components with tight tolerances and beautiful surface finishes can be obtained at a lower total cost.  CNC machine tools can also meet high standards of precision machining requirements.  High tolerance requirements for +/- 0.005 MM or higher.  

CNC machining in China has developed very rapidly in the past 30 years.  To date, there are more than 40,000 companies engaged in various machining operations, totaling 3 million machines and more than 9 million people engaged in processing activities.  China has long been the second largest manufacturer after the United States.  In particular, processing is very dynamic in China's Pearl River Delta and Yangtze River Delta regions.  Many of the very best and largest machinery manufacturing companies are based in the pearl River Delta region cities such as Shenzhen, Dongguan and Guangzhou.  They withdrew from the Chinese market very early and gained a good reputation for low price, good quality and high tolerance.
