FAQ
What makes your steel balls suitable for high-precision applications?
Our manufacturing process combines advanced CNC grinding machines with multi-stage lapping and polishing to achieve spherical tolerances below 0.001mm. Each ball undergoes laser roundness measurement and surface roughness testing before packaging, ensuring compliance with ISO 3290 G3 precision grade requirements.
How do you ensure consistent quality across large production batches?
We implement statistical process control (SPC) at every manufacturing stage, with real-time monitoring of key parameters like hardness, roundness, and surface finish. Our automated sorting systems reject any out-of-spec balls immediately, while our batch traceability system allows full quality history recall for every shipment.
Can you produce steel balls with non-standard dimensions?
Absolutely. Our custom manufacturing capabilities cover diameters from 0.3mm to 100mm with tolerances as tight as ±0.001mm. We regularly produce special sizes for medical, aerospace, and automotive applications where standard dimensions won’t suffice.
What surface treatments do you offer for corrosion resistance?
Our standard treatments include passivation for stainless steel balls and phosphate coating for carbon steel balls. For extreme environments, we provide nickel plating, chrome plating, and PVD coatings that offer 10x better corrosion resistance than untreated surfaces.
How quickly can you deliver custom orders?
Lead times depend on complexity and quantity. Standard custom orders typically ship in 15-20 days, while complex projects may require 30-45 days. We maintain strategic raw material stocks and flexible production scheduling to accommodate urgent requests whenever possible.
