Three minutes to take you to learn more about those things in cnc processing

　　CNC machining is also called computer gongs, CNCCH or numerical control machine tools. It is actually a kind of name from Hong Kong. Later, it was introduced into the Pearl River Delta of the mainland. It is actually CNC milling machines. In Guangzhou, Guangdong, Jiangsu, Zhejiang and Shanghai, it is called "CNC machining center"

　　General CNC machining usually refers to precision machining, CNC machining lathe, CNC machining milling machine, CNC machining boring and milling machine, etc.

　　Principle: simplify processing procedures

　　 Advantages: stable processing quality, high processing accuracy

　　Processing: Confirmation of CNC processing route

The feed processing route of the CNC lathe refers to the path that the turning tool moves from the tool setting point (or the fixed origin of the machine tool) until it returns to this point and ends the processing program, including the path of cutting processing and the non-cutting of the tool in and out Empty travel path.

　　The feed route of finishing machining is basically carried out along the part contour sequence. Therefore, the focus of determining the feed route is to determine the feed route of rough machining and idle stroke.

　　In CNC lathe processing, the determination of the processing route generally follows the following principles.

　　①The accuracy and surface roughness of the processed workpiece should be guaranteed.

　　② Make the processing route the shortest, reduce the idle travel time, and improve the processing efficiency.

　　③Simplify the workload of numerical calculation as much as possible and simplify the processing procedure.

　　④For some reusable programs, subroutines should be used.

　　 CNC advantages and disadvantages

　　 CNC machining has the following advantages:

　　①The number of tooling is greatly reduced, and complex tooling is not required for processing parts with complex shapes. If you want to change the shape and size of the part, you only need to modify the part processing program, which is suitable for new product development and modification.

　　②The processing quality is stable, the processing accuracy is high, and the repeat accuracy is high, which is suitable for the processing requirements of aircraft.

　　③The production efficiency is higher in the case of multi-variety and small batch production, which can reduce the time of production preparation, machine tool adjustment and process inspection, and reduce the cutting time due to the use of the best cutting amount.

　　④ It can process complex profiles that are difficult to process by conventional methods, and even process some unobservable processing parts.

　　The disadvantage of CNC machining is that the machine tool is expensive and requires a high level of maintenance personnel.

　　CNC Machining (CNC Machining) 　CNC Machining refers to processing with numerical control processing tools. CNC index-controlled machine tools are programmed and controlled by CNC machining languages, usually G codes. The CNC machining G code language tells the Cartesian position coordinates of the machining tool of the CNC machine tool, and controls the feed speed and spindle speed of the tool, as well as the tool changer, coolant and other functions. Compared with manual machining, CNC machining has great advantages. For example, the parts produced by CNC machining are very accurate and repeatable; CNC machining can produce parts with complex shapes that cannot be completed by manual machining. Numerical control machining technology is now widely promoted. Most machining workshops have NC machining capabilities. The most common NC machining methods in typical machining workshops are CNC milling, CNC turning, and CNC EDM wire cutting (electric discharge wire cutting). The tools for CNC milling are called CNC milling machines or CNC machining centers. The lathe that performs CNC turning processing is called a CNC turning center. CNC machining G code can be programmed manually, but usually the machining workshop uses CAM (computer aided manufacturing) software to automatically read CAD (computer aided design) files and generate G code programs to control CNC machine tools.
