Import Tips
• Document helical angle capability and differential mechanism to distinguish from straight spur gear hobbers
• Ensure electrical compliance (IEC standards) with test certificates for smooth clearance
• Avoid classifying as gear grinding (8461.40.20); emphasize roughing/cutting function
