Surface Grinding FAQs

What’s the difference between surface grinding and milling?

Surface grinding uses an abrasive wheel to achieve fine finishes and tight flatness, while milling is better suited for material removal and contouring.

Can you hold tolerances under 0.001"?

Yes — whether in-house or through our partners, we routinely achieve tolerances of ±0.0005” on flat grinding jobs.

Is the grinding done at your facility?

Some grinding is done at our Ontario location. For higher volumes or specialty materials, we may route the job through one of our certified grinding partners in Canada.
