Requirements of materials for precision machining

November 11, 2022

Precision machining is not possible for all materials. Some materials are too hard, exceeding the hardness of the machined equipment parts, the possibility of parts breakage is high, therefore? Such materials are not suitable for precision machining. Unless the parts are made of special materials or laser cutting. What are the material requirements for precision machining?

The materials for precision machining are divided into two kinds, metal materials and non-metal materials. For metal materials, the hardness is greater than stainless steel plate, followed by pig iron, followed by copper, and finally aluminum. The processing of porcelain, plastic, etc. is the processing of non-metallic materials. Dongguan precision machining requirements for material hardness, in some places, the higher the hardness of the material the better, limited to the hardness requirements of the processing equipment parts, the processing of the material can not be too hard. Suppose than the parts can not be processed.

Precision machining material hardness is moderate, at least one level lower than the hardness of the parts, together with the effect of processing parts is what, effective choice of parts. Dongguan precision machining of the material requirements and some, any material is not suitable for processing. For example, soft or hard material, the former does not need to be processed, the latter can not be processed. Therefore? Before processing must pay attention to the relative density of the material, assuming that the relative density is too large, the hardness is also very large, the hardness exceeds the parts (CNC lathe turning tool) can not be processed, not only will damage the parts, but also continue to pose a risk. For example, the lathe tool fly out of the injury, etc.. Therefore? Generally speaking, about mechanical professional processing, the material is less hard than the tool, can be processed.
