Classification of machining

The editor of Wuxi Tiecheng Machinery Factory will talk to you about the classification of machining. Our factory is a machinery manufacturing enterprise integrating design, development, manufacturing, and domestic sales and foreign trade services. The benchmarks of machining can be divided into design benchmarks and Two types of process benchmarks:
Design datum: The datum used to determine the position of other points, lines and surfaces on the part drawing is called the design datum.
Technology datum: The datum used in the process of processing and assembly of parts. Process benchmarks are divided into assembly benchmarks, measurement benchmarks and positioning benchmarks according to different uses.
A. Assembly datum: The datum used to determine the position of the part in the component or product during assembly is called the assembly datum.
B. Measurement datum: The datum used to test the size and position of the processed surface is called the measurement datum.

C. Positioning datum: The datum used for positioning the workpiece during processing is called the positioning datum. As the surface of the positioning reference, only the unprocessed surface of the blank can be selected in the process, and this positioning surface is called the rough reference. In the subsequent processes, the machined surface can be used as a positioning reference, and this positioning surface is called a fine reference.
The products of Wuxi Tiecheng Machinery Factory are widely used in: machine tools, shipbuilding, medical treatment, power generation, textiles, printing, metallurgy, mining, gear drives, engineering machinery, petrochemicals, lifting equipment, etc.
