Customized Milling CNC Precision Machining Lathe Parts

Preparation before processing
     Material property analysis: After hot forging, the internal structure of copper, stainless steel, and aluminum parts is more compact and the mechanical properties are improved, but the processing difficulty is also increased accordingly. Copper has good electrical conductivity, thermal conductivity, and corrosion resistance; stainless steel has high strength and strong corrosion resistance; aluminum has the characteristics of low density, high strength, and easy processing. Before processing, you need to fully understand these characteristics in order to select appropriate processing parameters.
Tool selection: Different tools need to be used for different metal materials. When processing copper parts, tungsten steel tools or diamond tools can be selected to ensure the wear resistance and cutting performance of the tools; for stainless steel, due to its serious work hardening phenomenon, tools with higher hardness and wear resistance should be selected, such as coated carbide tools, ceramic tools, etc.; aluminum parts are usually processed with diamond tools, PCD tools, etc., which have higher cutting speeds and surface quality.
Fixture design and selection: Design or select appropriate fixtures according to the shape, size, and processing requirements of hot forgings. The fixture should have sufficient rigidity and precision to ensure the position accuracy and stability of the workpiece during the processing, and prevent the workpiece from being displaced or deformed under the action of the cutting force.

Quality control and inspection
      Dimensional accuracy control: During the processing process, the size of the workpiece should be measured regularly, and the tool compensation value or processing parameters should be adjusted in time according to the measurement results to ensure that the dimensional accuracy of the workpiece meets the design requirements. Dimensional measurements can be made using measuring tools such as calipers, micrometers, and three-dimensional coordinate measuring machines.
Surface quality inspection: After hot-forged metal parts are turned and milled, the surface quality directly affects their performance and appearance. Through visual inspection, roughness meter measurement, etc., check whether the surface of the workpiece has defects such as knife marks, scratches, cracks, etc., and whether the surface roughness meets the requirements. For those with higher surface quality requirements, subsequent treatments such as polishing and grinding may be required.
Internal quality inspection: For some important hot-forged parts, internal quality inspections such as flaw detection are also required to check whether there are defects such as pores, inclusions, cracks, etc. inside the workpiece to ensure the quality and reliability of the workpiece.
