CNC machining is generally divided into rough machining, intermediate machining and finishing machining. It is the final processing in place to control the precision (accuracy) size. It’s not that CNC finishing tools are larger than rough turning tools. The tool used for finishing is a standard tool. When the workpiece is processed, there will be no surface roughness, and there will be no place where the processing is in place, and the tolerance dimensions can be guaranteed. The rough cutter processed by CNC is different. The degree of wear of the workpiece (a basic type of component failure) is different, and the machining accuracy (accuracy) is different.
The surface quality and machining accuracy (precision) of CNC machined parts are closely related. CNC machining is also called computer gong, CNCCH, and CNC machine tools are actually a name in Hong Kong. It greatly reduces the number of tooling. CNC machining does not require complex tooling to process parts with complex shapes. CNC machining is a new processing technology. The main work is to compile the processing program, that is, to convert the original manual work into computer programming. If you want to change the shape and size of the part, you only need to modify the part processing program. It is suitable for new product development and modification. Imagine a part with a very rough surface. Can its dimensional accuracy and shape and position accuracy be high?
The correct reference plane positioning should be selected during finishing, and a reasonable processing sequence, tool material and cutting parameters should be selected to ensure the final quality of the product. CNC machining is a process method for machining parts on CNC machine tools. The process regulations of CNC machine tool machining and traditional machine tool machining are generally consistent, but there have also been significant changes. A mechanical machining method that uses digital information to control the displacement of parts and tools. It is an effective way to solve problems such as a variety of parts, small batches, complex shapes, and high precision, and to achieve efficient and automated processing.
