FAQs

Frequently Asked Questions

Get quick answers to common questions about precision grinding.

What types of components are best suited for precision grinding?
Precision grinding is ideal for flat plates, shafts, bearings, dies, and aerospace components that require exceptional flatness and parallelism. We can maintain flatness within 0.001 mm on small critical parts.
Can precision grinding handle hardened materials?
Yes. Our grinding machines can process hardened steels up to 65 HRC, titanium, and superalloys, preserving mechanical integrity without inducing stress or distortion.
What surface quality can precision grinding achieve?
We deliver ultra-smooth finishes, typically 0.05–0.3 μm Ra, suitable for aerospace bearings, tooling surfaces, and precision molds, ensuring minimal friction and wear in operation.
How fast can precision-ground parts be delivered?
Lead time depends on part size and complexity. Standard aerospace parts ship in 4–7 days, while high-priority or prototype parts can be completed within 48–72 hours.
Do you provide post-grinding inspection and certification?
Yes. Every part can include CMM reports, flatness and parallelism verification, FAI (AS9102), and full material traceability. Optional surface treatments like passivation or plating are also available to meet aerospace standards.
