Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using standard carbon steel tools for cutting or grinding, leading to contamination and potential rust spots.Utilize dedicated stainless steel cutting tools, grinding discs, and abrasives to prevent cross-contamination.
Inadequate support during bending or forming, causing unintended deformation or stress risers.Provide sufficient and properly placed support during bending and forming operations to maintain dimensional accuracy and material integrity.
