Dalian precision machining is an efficient, high-precision, and high-quality machining method, which has important applications and significance in modern manufacturing industry. Through continuous technological innovation and equipment updates, precision machining can better meet market demand and make greater contributions to the development of the manufacturing industry.

The key technologies of precision machining include CNC technology, tool selection, tool running speed, and selection of cutting parameters. CNC technology is the key to achieving precision machining, and high-precision machining of workpieces can be achieved through CNC programming. The selection and use of cutting tools also directly affect machining efficiency and quality, and different workpieces need to choose suitable cutting tools for processing. The selection of tool operating speed and cutting parameters needs to be determined based on specific workpiece materials and processing requirements to ensure good cutting effects during the machining process.

What are the material requirements for precision machining in Dalian?

Hardness of materials: Precision machining usually requires the use of materials with higher hardness to ensure that the parts are not easily deformed and worn during use. Common materials include alloy steel, stainless steel, copper, aluminum, etc. below 55 degrees.

Uniformity of materials: The uniformity of materials has a significant impact on the machining accuracy and stability of parts. Therefore, precision machining usually requires a uniform and fine structure of materials without significant grain conditions.

Hardness changes of materials: During the machining process, hardness changes may occur, leading to a decrease in part accuracy or an increase in machining difficulty. Therefore, precision machining requires a small change in material hardness and good stability.

The heat treatment performance of materials: The heat treatment performance of materials is crucial for precision machining. The heat-treated materials should have high hardness and strength, while maintaining good processability.

Wear resistance of materials: Precision machining usually requires the use of materials with good wear resistance to ensure that parts are not easily worn out during long-term use and extend their service life.

One of the advantages of precision machining is that it can achieve high precision machining, typically achieving machining accuracy of micrometers or even smaller. This means that the components manufactured during precision machining can have very high precision and stability, thus meeting high engineering requirements.

Precision machining is a high-precision machining process widely used in aerospace, automotive manufacturing, electronic equipment, medical devices, and other fields. It is a machining method that uses high-precision equipment such as CNC machine tools to cut, polish, and turn workpieces using various cutting tools, in order to achieve the requirements of workpiece accuracy, surface smoothness, and dimensional accuracy.
