What is cnc machining professinal factory customized cnc machining parts:
Introduction:
Generic CNC processing usually refers to computer digitization control precision machinery processing, CNC processing car processing, CNC processing milling machine, CNC processing boring milling machine etc.
CNC is also called computer gong, CNCCH or CNC machine tool, which is actually a name in Hong Kong. Later, it was introduced to the Pearl River Delta of the mainland. It is actually a CNC milling machine. Some people in Guangzhou, Jiangsu, Zhejiang and Shanghai call it "CNC machining center". It is a new type of processing technology, and its main job is to compile processing programs, that is, to convert the original manual work into computer programming. Of course, manual processing experience is required
Determination of CNC machining route

CNC lathe feed processing route 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 non-cutting processes such as cutting in and out of the tool. Empty travel path.
The feed route of finishing machining is basically carried out sequentially along the contour of its parts. Therefore, the focus of determining the feed route is to determine the feed route of rough machining and empty stroke.
In CNC lathe processing, the determination of the processing route generally follows the following principles.
① The accuracy and surface roughness of the workpiece to be processed should be guaranteed.
② Make the processing route the shortest, reduce the idle travel time, and improve the processing efficiency.
③ Try to simplify the workload of numerical calculation and simplify the processing procedure.

④ For some reusable programs, subroutines should be used
Advantages and disadvantages of CNC

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 precision is high, and the repetition accuracy is high, which is suitable for the processing requirements of aircraft.
③In the case of multi-variety and small-batch production, the production efficiency is high, which can reduce the time for production preparation, machine tool adjustment and process inspection, and the cutting time is reduced due to the use of the optimal 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 equipment is expensive and requires a high level of maintenance personnel.

Numerical control machining refers to machining with numerically controlled machining tools. CNC index control machine tools are programmed and controlled by CNC machining language, usually G code. The CNC machining G code language tells the CNC machine tool which Cartesian position coordinates to use, and controls the tool feed speed and spindle speed, as well as tool changer, coolant and other functions. Compared with manual processing, 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 processing. CNC machining technology has been widely promoted. Most machining workshops have CNC machining capabilities. The most common CNC machining methods in typical machining workshops are CNC milling, CNC turning and CNC EDM wire cutting (wire electric discharge cutting).
The tool for CNC milling is called CNC milling machine or CNC machining center. A lathe for CNC turning is called a CNC turning center. CNC machining G code can be programmed manually, but usually machining workshops use CAM (Computer Aided Manufacturing) software to automatically read CAD (Computer Aided Design) files and generate G code programs to control CNC machine tools
