CNC machining usually refers to computer digital control of precision machining, CNC lathe, CNC milling machine, CNC boring and milling machine, etc. CNC precision processing, integration of industry resources, the use of casting, forging, powder metallurgy, extrusion and other raw materials processing, reduce costs. <br>
The machining method of CNC workpiece surface first depends on the technical requirements of machining surface. However, it should be noted that these technical requirements are not necessarily the requirements specified in the part drawing, and sometimes they may be higher than the requirements in the part drawing due to technological reasons. <br>
For example, because the datum does not coincide, the machining requirements for the surface of some CNC parts are increased. Or because it is used as a precision benchmark, it may put forward higher processing requirements. <br>
The machining method of CNC workpiece surface first depends on the technical requirements of machining surface. However, it should be noted that these technical requirements are not necessarily the requirements specified in the part drawing, and sometimes they may be higher than the requirements in the part drawing due to technological reasons. For example, if the surface roughness of some CNC machined parts is increased due to the non coincidence of datum, the following factors should be considered when selecting the machining method: < br >
1. Any kind of CNC machining method can obtain a large range of machining accuracy and surface roughness, but only in a narrow range is economic, and the machining accuracy in this range is economic machining accuracy. Therefore, when selecting the processing method, the corresponding processing method which can obtain the economic processing precision should be selected. <br>
2. The material properties of CNC parts should be considered. <br>
3. The structure shape and size of CNC parts should be considered. <br>
4. Consider productivity and economic requirements. In mass production, advanced technology with high efficiency should be adopted. Even can fundamentally change the blank manufacturing method, can reduce the amount of machining labor. <br>
Su minte parts processing, CNC precision processing, many years of experience in precision hardware parts processing, Su minte parts processing, specializing in processing high precision parts with small tolerance and complex structure, CNC precision processing, integrating industry resources, using foundry, forging, powder metallurgy, extrusion and other raw materials processing to reduce costs. <br>
Fine parts processing methods, including the application of machining center programmability, reasonable preparation of NC machining program, application of machining center operation characteristics of human optimization of cutting parameters. The reasonable selection of tool geometry and the processing technology and measures of using ordinary high speed steel drill and end mill to process titanium alloy holes with high precision and large aperture ratio. <br>
The applicability of improved cutting tools, optimized cutting parameters and processing methods is verified through the processing of practical samples. Titanium alloy is a kind of commonly used superalloy, which is mainly used in the maintenance shell manufacturing of logging tools.
