What are the key points to pay attention to in stainless steel machining?

Stainless steel machining refers to the use of mechanical processing equipment such as CNC machine tools, milling machines, and drilling machines to process stainless steel materials in order to obtain parts of the desired shape and size. Stainless steel machining needs to pay attention to the following points: 1. Tool selection: Stainless steel materials have high hardness, toughness, and wear resistance, so suitable tools need to be selected for machining. Generally speaking, stainless steel machining requires the use of hard alloy cutting tools or high-performance ceramic cutting tools. 2. Coolant selection: Stainless steel materials are prone to high temperatures during processing, so coolant is needed to reduce the temperature and prevent workpiece deformation or cracking. Common cooling fluids include cutting oil, emulsion, etc. 3. Selection of cutting parameters: The selection of cutting parameters for stainless steel machining is crucial for machining quality and efficiency. The parameters such as cutting speed, feed rate, and cutting depth need to be reasonably selected based on the performance of the machine tool and cutting tool, as well as the material and shape of the workpiece. 4. Processing sequence and clamping method: The processing sequence and clamping method of stainless steel machining also have a significant impact on processing quality and efficiency. It is necessary to choose the appropriate clamping method and processing sequence according to the material, shape, and processing requirements of the workpiece to ensure the accuracy and processing efficiency of the workpiece. 5. Surface treatment: The surface of stainless steel after machining usually needs to be treated to obtain the desired appearance and quality. Common surface treatment methods include polishing, wire drawing, sandblasting, etc.
