What is Surface Grinding?
Surface grinding is a precision finishing process that uses an abrasive wheel to produce extremely flat surfaces and tight tolerances that are difficult to achieve through machining alone. It's essential for components that require precise flatness, parallelism, or specific surface finish requirements — such as bearing surfaces, seal faces, gauge blocks, and precision tooling.
RPM Machining Ltd. coordinates surface grinding through our trusted partner network. Whether your parts need grinding as a final finishing step after heat treatment, or you need precision flat surfaces ground to exacting tolerances, we manage the process from machining through grinding to deliver a finished component.
Our Process
Machining with Grinding Allowance
Parts are precision-machined at our Yorkton facility with appropriate stock left for the grinding operation, ensuring the final ground surface meets your exact specifications.
Grinding Specification Review
We review your surface finish, flatness, parallelism, and tolerance requirements to ensure the grinding operation is set up correctly.
Partner Coordination
We coordinate with our specialized grinding partners, providing full dimensional specifications and material details for optimal results.
Precision Grinding
Your parts are ground using precision surface grinding equipment to achieve the required flatness, parallelism, and surface finish.
Final Inspection
Ground parts are measured and inspected to verify they meet your tolerance and surface finish specifications.
Delivery
Fully machined and ground parts are packaged and shipped anywhere in Canada — or available for local pickup at our Yorkton facility.
