Grinding is where a machined part gets its final size and surface. Union Enterprises keeps both cylindrical and surface grinding in-house, so a tight-tolerance job moves straight from the mill or the lathe to the grinder without leaving the building or waiting on an outside vendor’s schedule.

Where Grinding Fits in a Job
Most ground parts arrive at the grinder already milled or turned. Pairing grinding with in-house milling and turning keeps a multi-step part under one roof from first cut to final inspection, which removes both the transit time and the handling risk of moving a nearly finished part between shops.
Finished sizes are verified on a fully automatic three-axis OGP SmartScope. Regulated work ships with first article inspection and material traceability attached.
