CNC milling of high-precision stainless steel complex parts

In the CNC milling process of high-precision stainless steel complex parts, the following key aspects need to be considered:

1. Tool selection: Typically, carbide tools, or even coated carbide tools, are chosen to enhance tool wear resistance and cutting performance, thereby addressing the high cutting forces and high temperatures encountered during stainless steel machining.
2. Cutting parameter settings: These include cutting speed, feed rate, and cutting depth, which must be reasonably set based on the grade of stainless steel, the complexity of the part, and precision requirements to ensure processing quality and efficiency while minimizing tool wear.
3. Machining Process Planning: For complex parts, a reasonable machining sequence must be established, such as performing rough machining to remove most of the material allowance first, followed by semi-finishing and finishing to gradually improve part precision. Additionally, measures must be taken to avoid interference issues during the machining process.
4. Precision Control: Through the high-precision control of the CNC system, combined with the machine tool's inherent high-precision performance, the dimensional accuracy, shape accuracy, and positional accuracy of the part are ensured to meet requirements.
