CNC Machining

The application of CNC Machining has become increasingly common. In the process of precision part machining, not all materials are suitable. For example, some materials have excessive hardness, which may damage the parts during the Machining Process. This also indicates that such materials cannot be used for precision machining. In this regard, the basic requirement for precision part machining is to confirm the density of the material before machining. If the density is too high, that is, when the hardness is too high, and exceeds the hardness of the machining tool, it cannot be machined. Generally, for mechanical machining, the material needs to be lower than the hardness of the machine tool in order to proceed with machining. For metallic materials, the order of hardness from highest to lowest should be stainless steel, cast iron, copper, aluminum, etc. The corresponding materials are suitable for different precision parts, and correct differentiation is needed. CNC machining refers to the machining of components on CNC machining machines.

Preparation for CNC machining: methods and steps for reading part drawings. The general steps for reading part drawings are: first, look at the title bar to understand the overview of the parts; Look at the graphics and imagine the structural shape of the parts; Check the dimensions three times and clarify the size of each part; Look at the technical requirements four times and master the quality indicators. To accurately grasp the quality requirements of parts, such as surface roughness, tolerances and fits, heat treatment methods, etc., in order to reasonably arrange the processing technology and process. Overall consideration. By integrating the understood structural shapes, dimensional annotations, and technical requirements, one can comprehensively understand the part drawings. Sometimes, in order to understand complex part drawings, it is necessary to refer to relevant technical information, including the position of the component in the assembly drawing and the drawings of the associated parts.
