FAQ
What makes super precision steel balls different from standard steel balls?
Super precision steel balls are manufactured to much tighter tolerances (typically G3-G100 grades) compared to standard commercial balls (G200-G2000). This means they have more consistent roundness, surface finish, and dimensional accuracy, making them essential for high-performance applications like aerospace bearings, medical devices, and precision instruments where even microscopic deviations can affect performance.
How do you ensure the quality consistency of large production batches?
We implement a comprehensive quality management system that includes: 1) Raw material inspection before production, 2) In-process quality control at every manufacturing stage, 3) 100% final inspection using advanced measuring equipment, and 4) Statistical process control (SPC) to monitor production parameters. Our ISO/IATF certifications require regular third-party audits to maintain our quality standards.
What is the minimum order quantity for custom super precision steel balls?
While our standard products have no MOQ requirements, custom orders typically start from 5,000 pieces for smaller diameters (0.3-10mm) and 1,000 pieces for larger diameters (10-100mm). The exact MOQ depends on the complexity of your customization requirements. We recommend contacting our sales team with your specific needs for an accurate quotation.
How long does it take to produce custom super precision steel balls?
Production lead times vary based on order quantity and complexity: 1) Sample orders: 7-15 working days, 2) Small batch production (5,000-50,000 pcs): 15-25 working days, 3) Large batch production (50,000+ pcs): 25-40 working days. We maintain stock of standard sizes for immediate shipment and can expedite production for urgent orders when possible.
What surface treatments are available for super precision steel balls?
We offer multiple surface treatment options to enhance performance: 1) Polishing for ultra-smooth surfaces (Ra ≤ 0.01μm), 2) Chrome plating for corrosion resistance, 3) Black oxide coating for lubricity, 4) Passivation for stainless steel balls, 5) Custom coatings based on your requirements. Our engineering team can recommend the best treatment based on your application environment.
