The Difference Between CNC Machining Of Mechanical Parts And Ordinary Machining

In the precision machinery parts processing industry, with the “miss, a thousand miles” this saying, very appropriate.Below take you to understand the difference between cnc machining of precision machinery parts and ordinary processing?1. Differences in processing methods: The traditional processing technology of mechanical parts should be carefully used in the processing method, in the Cnc Machine tool processing will become simple and feasible.In the process of hole position machining, the blank tool method and dressing method used in the traditional machining process are replaced by the NUMERICAL control dressing method in the numerical control machining process.
2. High-speed processing of CNC machine parts has incomparable advantages over traditional processing technology. The following is a specific illustration of mold processing as an example.In the traditional processing technology, it usually needs more than one processing procedure to complete the mold processing task, but the high-speed processing only needs 1-2 procedures to complete, and because of the high precision of high-speed processing, there is no need to carry out the traditional electrical processing and grinding processing.
3. Difference in tool selection: different processing techniques and methods require different tools, especially in high-speed cutting, CNC machine tool precision machinery parts processing efficiency and quality have been greatly improved, and the cutting deformation and processing cycle are greatly reduced.Compared with traditional machining technology, CNC precision machining has significantly enhanced the performance of all aspects of the tool, the installation of a single tool into a number of tools.
4. Difference of thermal deformation: Thermal deformation is one of the inevitable problems in the process of workpiece cutting.In the process of precision machining, the thermal deformation will have a direct impact on the machining accuracy.There are many processes in the traditional processing mode, and the connection of each process has a certain buffer time, which can make the temperature of the parts drop before the next process of processing, effectively reducing the impact of thermal deformation.Numerical control machining can be continuously processed on multiple surfaces, cutting heat cannot be released in a timely manner, if by controlling the time interval of each procedure to prevent, and will affect the efficiency of machining parts.Therefore, when CNC machining of high precision mechanical parts is adopted, the method of cooling and finishing is also needed to reduce the influence of thermal deformation.
