Ultra-precision CNC lathes are quite complex. This complexity stems from the different types of machine tools, materials used, cutting tools, and cutting methods. The parameter settings for each lathe also vary. Therefore, operating a CNC lathe requires a certain level of expertise and a considerable period of learning and mastering the technology to ensure higher efficiency and better product quality in production and machining.
How should the machining process be divided when using an ultra-precision CNC lathe? This is a fundamental question. Generally, when dividing the process, the tool sequence should be based on the tools themselves. When using tools, one tool can completely machine all the parts that can be completed on the part. In addition, a second or third tool can be used to complete other parts of the part. In this way, as many parts as possible should be completed in the use of one tool. This can reduce the number of tool changes, reduce idle time, and avoid unnecessary errors.
When machining, you need to deal with parts in many parts. According to the structural characteristics of these parts, the parts to be machined can be divided into several types, such as internal shape, external shape, curved surface or flat surface, etc. Generally, when machining, you should first machine the flat surface and the positioning surface, and then machine the hole. In terms of graphic machining, you should start by machining the simpler geometric shapes, and then machine some more complex shapes. You can also divide it according to the level of precision, and machine the parts with lower precision first.
In addition, the machining process can also be divided into roughing and finishing stages. Parts that are more prone to deformation during machining should be divided in this way. Parts that may deform after roughing need to be machined first and then corrected. Parts that are roughed and finished should be processed separately. When dividing the process, certain principles should be strictly followed.
When machining parts on an ultra-precision CNC lathe, the parts are generally classified according to their structure and manufacturability, or according to the function of the machine tool. However, when faced with different parts, if it is not clear how to classify them, the principle of classification from simple to complex should be followed to ensure that the parts are machined reasonably and to reduce wear during the machining process.
