FAQs

Can you grind hardened parts?

Yes — we routinely finish-grind hardened tool steels and post-heat-treated parts with Rockwell hardness above 60.

What tolerances can you hold?

We provide grinding to ±0.0002" and honing to bore tolerances as tight as ±0.0001", depending on geometry and material.

Are these processes done in-house?

Some light grinding is handled in-house; we also coordinate high-precision grinding and honing with trusted Canadian partners — all managed by Pearson for quality control and traceability.
