Precision Grinding
Surface and cylindrical grinding for the tightest tolerances.
Need a ground surface or a tolerance machining alone won’t hold? Send a 2D PDF drawing and a 3D STEP file and a real person will quote it within 24-48 hours. No minimum order, standard lead time is 4-6 weeks (rush 1-2 weeks), and every part is inspected before it ships.

What We Make
When a part needs a tolerance or surface finish that machining alone won’t hold, grinding gets it there: flat surfaces, ground diameters, and precision pins. Often the finishing step on a milled or turned part.
Typical parts
- Precision ground pins
- Ground shafts and diameters
- Flat and parallel surfaces
- Hardened-part finishing
- Tight-tolerance gauge work
Questions
Before you send a job.
01 What tolerances can grinding hold?
Down to ±0.0001 in with fine surface finishes: the tightest work on the menu. Put the critical dimensions and finish callouts on your drawing and the part will be inspected to them.
02 Can hardened parts be ground?
Yes. Grinding is the normal way to finish hardened steel: pins, shafts, and flat surfaces all grind cleanly after heat treat.
03 Do you grind as a finishing step on machined parts?
Yes, that’s the most common case. A part gets milled or turned, then ground where the print calls for a tight tolerance or fine finish. Quote it as one job and it ships as one finished part.
04 What files do you need for a grinding quote?
A STEP file plus a PDF drawing with the tolerance and surface-finish callouts. The drawing matters most here: ground features live or die on the callouts.
05 Is there a minimum order for ground parts?
No. One gauge pin or a recurring production run: both are welcome.
