CNC Machining Refers To The Use Of CNC Machining Tools For Processing

CNC is also called computer gongs, CNCCH or CNC machine tools is actually a name in Hong Kong side, and later into the mainland Pearl River Delta, in fact, is the CNC milling machine, in the wide, Jiangsu, Zhejiang and some people called "CNC machining center" general CNC processing Refers to the precision machining, CNC machining lathes, CNC milling machines, CNC machining boring and milling machines.

Advantages and Disadvantages of CNC

CNC machining has the following advantages:

① greatly reduce the number of tooling, processing complex shape of the parts do not need complex tooling. To change the shape and size of the part, only need to modify the parts processing procedures for new product development and modification.

② processing quality and stability, high precision, repeat the high precision, to meet the processing requirements of the aircraft.

③ multi-species, low-volume production conditions, high production efficiency, can reduce production preparation, machine adjustment and process inspection time, and because the use of the best cutting the amount of cutting time.

④ can be processed conventional methods difficult to process the complex surface, and even processing some of the processing can not be observed parts.

The drawback of CNC machining is that machine equipment is expensive and requires a high level of maintenance personnel.

CNC machining CNC machining is the use of CNC machining tools for processing. CNC CNC machine tools from the NC processing language programming control, usually G code. CNC machining G code language tells the CNC machine tool processing tool using what Cartesian position coordinates, and control the tool feed speed and spindle speed, and tool changer, coolant and other functions. CNC machining relative to the manual processing has great advantages, such as CNC machining parts are very accurate and reproducible; CNC machining can produce manual processing can not be completed with complex shape parts. CNC machining technology is now widely popular, most of the machining workshop has a CNC machining capacity, the typical machining workshop in the most common CNC machining methods are CNC milling, CNC and CNC EDM line cutting (EDM wire cutting). The tool for CNC milling is called CNC milling machine or CNC machining center. CNC lathe for CNC turning is called CNC turning center. CNC machining G code can be manually programmed, but usually machining workshop with CAM (computer aided manufacturing) software automatically read CAD (computer aided design) file and generate G code procedures, CNC machine tools to control.
