In the field of CNC machining, not all materials can be processed. Many raw materials have too much hardness, exceeding the hardness of CNC machining parts, which may damage the machine tool or break the workpiece. Reasonable materials, processing equipment and special tools should be selected.
The materials for CNC machining parts are divided into two categories, metallic materials and non-metallic materials. For metal materials, the hardness is stainless steel the highest, followed by cast iron, followed by copper, and finally aluminum. The processing of ceramics, plastics, etc. belongs to the processing of non-metallic materials. The raw materials used by RuiSiCheng for CNC machining parts are also various. So, what are the specific requirements for the materials?
The first is the requirement for the hardness of the material. For some occasions, the higher the hardness of the material, the better, but it is limited to the hardness requirements of the machined parts. The material of CNC machining parts cannot be too hard. If it is harder than the machined parts, it cannot be machined. That is to say, the material is moderately soft and hard, at least one grade lower than the hardness of the parts, and at the same time, it also depends on the conditions of the processing equipment for processing the parts, and the material selection for the parts is reasonable.
In addition, before CNC machining parts, we must pay attention to the density of the material. If the density is too high, it is equivalent to a large hardness. If the hardness exceeds the hardness of the lathe tool, it cannot be processed, which will not only damage the parts, but also cause Dangerous, such as the knife flying out and hurting people.
In short, CNC machining parts still have some requirements for materials, not all materials are suitable for machining, such as too soft or too hard materials, the former is not necessary for machining, while the latter cannot be machined. Generally speaking, for mechanical processing, the material should be lower than the hardness of the machine tool, so that it is easy to process, otherwise special custom tools are used to complete it.
