Cost-Effective & Reliable Stainless Steel Machining Tips
At TiRapid, we know stainless steel can be challenging to machine—but with the right approach, you get excellent results without unnecessary risk. Here are our key tips:
1. Select the Right Alloy
Choose the material that matches your performance needs. Free-machining grades, for example, reduce cycle time when extreme corrosion resistance isn’t required.
2. Use High-Quality Cutting Tools
For stainless steel, use premium end mills and drills made of tungsten carbide or molybdenum-based HSS. These tools handle stress better and deliver a superior surface finish.
3. Control Heat Effectively
Excessive heat can cause deformation and shorten tool life. Reduce cutting speeds when necessary, apply proper coolants, and pause machining if temperatures rise excessively.
4. Manage Chip Formation
Pecking and chip-breaking cycles help avoid long, stringy chips and keep machining stable. Always check tool sharpness—dull tools increase chip problems and reduce accuracy.
5. Maintain Dimensional Stability
Use proper speeds and feeds, minimize vibration, and ensure workpiece stability to prevent deformation and tolerance errors.
TiRapid applies these strategies daily to deliver stainless steel parts with tight tolerances, excellent finishes, and dependable lead times.
