Advantages of Stainless Steel CNC Machining Services
- CNC machining guarantees accurate contouring and hole drilling over stainless steel, maintaining strict tolerances, which are essential for complex systems.
- CNC machining along with stainless steel results in smooth surfaces and tight tolerances. The look and functionality are furthered by processes such as polishing and passivation.
- Resistant to corrosion because of the protective layer of oxide formed by its chromium content, steel is widely used in extreme environments with moisture, chemicals, and high temperatures.
- CNC machining makes sure to ensure the highest levels of accuracy which reduce waste and errors, while sustaining a uniform level of quality. It’s scalable and is suitable for both prototypes and bulk manufacturing.
- CNC machining is perfect for manufacturers needing specific stainless steel components like turbine blades and fasteners in the aerospace industry where detail is crucial.
Stainless Steel CNC Machining Design Considerations
- Thermal Conductivity: The thermal conductivity of stainless steel is very low and, therefore, may result in concentrating heat at the cutting edge, possibly impacting tools and machining performance.
- Optimized Cutting Speeds and Feeds: For prevention of overheating of the tool, the cutting speed has to be lower (approx. 30-80 m/min depending on the grade) or the feed rate moderate.
- Coatings: For enhanced durability and increased heat resistance, apply coatings such as titanium nitride (TiN) or aluminum titanium nitride (AlTiN).
- Post-Processing: Important steps like grinding, polishing, or passivation might be necessary to achieve the desired aesthetic looks and increase the metal's corrosion resistance.
- Inspection: Check tolerances periodically using measuring devices such as a caliper or CMM to ensure such tolerances are within the specified limits.
