Expert Q&A Section
Q: What are the primary applications for SM shape burrs?
A: The oval profile excels in mold making, die casting repairs, and complex contour work where both flat and curved surfaces need blending.
Q: How does the oval shape compare to standard ball or cylinder shapes?
A: The SM shape combines the material removal rate of cylindrical burrs with the contouring ability of ball shapes, reducing tool changes.
Q: What coolant recommendations do you have for these burrs?
A: For optimal performance, we recommend using water-soluble coolants at 5-8% concentration for most applications.
Q: Can you provide custom oval ratios (major/minor diameter)?
A: Yes, we can manufacture custom oval profiles with specific diameter ratios to meet unique application requirements.
Q: What's your production capacity for bulk orders?
A: Our facility can produce up to 50,000 pieces monthly, with consistent quality control throughout production runs.
