In the manufacturing process of precision parts processing, due to the different production requirements and conditions of various parts, the manufacturing process schemes are also different. When the same parts are produced using different process schemes, their production efficiency and economic benefits are also different. Under the premise of ensuring the quality of the parts, the process of drawing up a reasonable and feasible process plan with good comprehensive technical and economic benefits is called the process design of the parts.https://www.cncmachiningptj.com/highspeedmachining Furthermore, there are certain requirements for the selection and quality of materials.
Precision machining, not all materials can be precision machining, some materials are too hard, exceeding the hardness of the machined parts, the machine parts may collapse, so these materials are not suitable for precision machining, unless they are special Machine parts made of materials, or laser cutting.
Precision parts processing
For precision machining parts, they are divided into two categories, metallic materials and non-metallic materials. For metal materials, stainless steel has the highest hardness, followed by cast iron, followed by copper, and finally aluminum. The processing of ceramics, plastics, etc. belongs to the processing of non-metallic materials. For material hardness requirements, 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 machined material should not be too hard. If it is harder than the machine part, it cannot be machined. The material is moderately soft and hard, at least one grade lower than the hardness of the machine part. At the same time, it also depends on the purpose of the machined device and the rational selection of the machine part.
Precision machining still has some requirements for materials. Not all materials are suitable for processing, such as materials that are too soft or too hard. The former is not necessary for processing, while the latter cannot be processed.
Therefore, you must pay attention to the density of the material before processing. If the density is too high, the hardness is also large. If the hardness exceeds the hardness of the machine part (lathe tool), it cannot be machined, not only will damage the part, but also It will cause danger, such as the turning knife flying out and hurting people. Therefore, in general, for mechanical processing, the material material must be lower than the hardness of the machine knife, so that it can be processed.
