The parts produced by precision machining in Dalian require very high precision. Therefore, the operation level of technicians is relatively harsh, and the performance and accuracy of equipment are also very high. Similarly, as raw materials for production, the materials shall not be careless. It may be just a part, or it may be the core component of a mechanical equipment.

In a word, it is very important and plays an irreplaceable role. There are two processes for precision machining and manufacturing of these precision parts, one is hot machining and the other is cold machining. Hot working is to make the parts undergo chemical or physical changes under very warm conditions through heat treatment to meet the requirements of shape change.

Cold machining is to meet the requirements of shape change without chemical and physical changes at room temperature. Generally, cutting technology is adopted. In the future, on the premise of meeting the requirements of machining and environmental protection, precision machining will be combined with science and technology to become an important and sustainable science. First of all, we have to make it clear that not all workpieces of any material can be precision machined.

If the hardness of the processed material is higher than that of the equipment (machine tool turning tool), it will not only cause certain damage to the workpiece, but also wear and even collapse the tool, and even the turning tool will fly out and injure the operator by mistake. Therefore, we have to analyze the material of the machined workpiece and whether it is suitable for precision turning and other work by precision machining.
