Can you turn large shafts in-house?
We can turn mid-size shafts in-house, but extra-large or long components are fulfilled through our Canadian partner network with heavy lathe capacity.
What materials can you turn?
We support turning of carbon steel, stainless, aluminum, bronze, tool steels, and more. Let us know your spec and we'll confirm suitability.
Do you provide inspection reports?
Yes. Dimensional reports and certificates of compliance are available on request. CMM verification is included for most large critical parts.
