CNC FINISHING
The steps between "machined" and "done." Deburring, precision grinding, EDM, part marking, and the finish work that decides whether a part looks like it came from a real shop.
THE DETAIL
THE PART ISN'T DONE WHEN THE CUT
A part comes off the machine with burrs, sharp edges, and no identity. Finishing is where it becomes something you can actually put in an assembly — deburred, ground to spec where it matters, marked so it's traceable, and checked before it ships.
Deburring with handheld and precision tooling
Precision grinding for critical surfaces and tolerances
EDM for features conventional cutting can't reach
Laser engraving and part identification for traceability
Final inspection before release
THE PROCESSES
FINISHING IN-HOUSE
Finishing that stays under our roof, so the part never leaves our control between the machine and the box.

THE WORK
WHAT FINISHING COVERS
Four things that happen after the last cut.
01
DEBURRING
Every machined edge gets addressed — handheld rotary for the big stuff, precision work where the tolerance is tight. A part with burrs isn't finished, it's dangerous.
02
GRINDING & EDM
Precision grinding for surfaces the mill can't hold, and EDM for features conventional cutting can't reach. The hard-to-do finish work that keeps a job in-house instead of out at a vendor.
03
PART MARKING
Laser engraving for part numbers, identification, and traceability. Tier-1 supply chains need to know which part is which, and it gets marked here.
04
FINAL INSPECTION
The finished part gets verified against the print before it's released. Finishing and inspection are the same handoff, not two separate departments.
QUALITY
FINISH IS CHECKED, NOT ASSUMED
Finish quality is easy to eyeball and easy to get wrong. Ours gets verified against the print — features, surfaces, and markings confirmed before the part is cleared to ship, with the same inspection discipline that governs the machining.
Features verified against the print
CMM inspection for tight-tolerance validation
Part marking confirmed for traceability
Deburring and finish checked before release
QUESTIONS
STRAIGHT ANSWERS
DO YOU DEBURR AND FINISH IN-HOUSE?
Yes. Deburring, precision grinding, EDM, and part marking all happen in the same building as the machining, so the part never leaves our control between the cut and the box.
CAN YOU DO PRECISION GRINDING?
Yes — precision grinding is part of the shop, for critical surfaces and tolerances the mill or lathe can't hold on its own.
DO YOU OFFER EDM?
Yes. EDM handles features and geometry that conventional cutting can't reach — a normal part of our toolmaking and finishing work.
CAN YOU MARK OR ENGRAVE PARTS FOR TRACEABILITY?
Yes. We run laser engraving and part identification in-house, which matters when a Tier-1 supply chain needs every part traceable.
NEXT STEP
NEED IT FINISHED RIGHT?
Print, model, or the actual part — however you've got it, send it over. You'll get a straight answer on whether we can make it, what it takes, and how long it runs.
