Machining precision parts for material requirements?
Fine parts processing, not a material can be, some material hardness is too large, greater than the hardness of machining parts, parts can be able to collapse, so these materials are not suitable for fine machining, unless special material into parts, or laser cutting.
Information on fine parts processing is divided into two categories, metal materials and non-metallic materials.
About a metal material, the hardness of stainless steel, followed by cast iron, followed by copper, aluminum final.
And ceramics, plastics and other processing are attributed to the processing of non-metallic materials.
1. The first is the need for material hardness, for some occasions, the material is the harder the better, and this is just limited to mechanical processing, material processing can not be too hard, harder than if the parts can not be processed if it is of.
2. Secondly, moderate hardness material, at least one level lower than the hardness of parts, along with the role of processing equipment, but also what to do with, a reasonable selection of parts.
In short, the demand for fine parts processing materials still have some, not what materials are suitable for processing, for example, say it is too soft or too hard material, the former is not a necessary process, which can not be processed.
Therefore, the most basic one that is in front of the processing must pay attention to the density of the material, if the density is too large, the equivalent of hardness is also great, but if you go beyond the mechanical hardness (lathe tools) hardness, which can not be processed not only can damage the parts, but also the formation of risk, such as turning out to fly collapse wounding. Therefore, in general, is working on machinery, raw materials is lower than the hardness of the machine tool, so talent is processed.
