Wexmar provides precision deburring services as part of every machined part we ship. Burrs on sealing surfaces, cross holes, threads, and edges cause assembly problems, leaks, cut O-rings, and contamination, so we plan deburring into the machining process rather than treating it as an afterthought. Buyers searching for a precision deburring machine shop or deburring near me in Central New York get burr-free parts machined and finished in one place, at our Canastota shop near Syracuse.
What deburring is
A burr is the thin ridge of material left where a cutting tool exits a surface. Every machining process creates some burr, and the size depends on material, tool sharpness, and the path of the cut. Deburring removes those ridges and leaves a controlled edge condition, usually a small chamfer or radius called an edge break. Good deburring is both a machining problem and a handwork problem: the cleanest results come from toolpaths that minimize burrs and add chamfers in the machine, followed by bench work only where a machine cannot reach.
When deburring matters most
- Hydraulic and pneumatic manifolds where intersecting passages leave internal burrs
- Sealing surfaces, O-ring grooves, and seal bores that must not cut elastomers
- Threaded holes and thread starts where burrs block gages or mating parts
- Medical hardware and instrumentation with tight cleanliness expectations
- Parts that will be plated, anodized, or passivated, where burrs trap chemistry or flake off
- Assemblies where loose burrs could become debris in moving components
How Wexmar deburrs
In the machine
Our programmers add chamfer and edge-break passes on the CNC lathes, Swiss machines, and horizontal machining centers wherever the geometry allows. Live tooling on our Mazak and Doosan lathes and our Maier Swiss machines lets us chamfer cross holes and flats in the same setup. On the Mazak horizontal machining centers, back-chamfer tools and deburring toolpaths clean hole exits on the far side of walls without flipping the part.
At the bench
Where a machine cannot reach, trained staff deburr by hand with scrapers, countersinks, abrasive tools, brushes, and hand tools. Intersecting passages in manifolds are inspected with lights and magnification and deburred at the break-through. Our tool room supports custom deburring tools when a part needs one. See our deep hole drilling page for how we plan intersecting passages.
Typical edge conditions
| Callout | Typical result |
|---|---|
| Break sharp edges (no size given) | 0.005 to 0.015 in chamfer or radius |
| Specified chamfer | Per print, typically ±0.005 in |
| Specified edge radius | Per print, typically ±0.005 in |
| Cross hole intersections | Burr-free under visual inspection with magnification |
| Thread starts | Chamfered, partial thread removed |
| Sealing edges and O-ring grooves | Smooth, burr-free, per print finish |
If your print states "no burrs" without an edge size, we apply the break sharp edges range above. If an edge must remain sharp for function, such as a cutting or metering edge, please note it on the drawing.
Materials
Burr behavior varies by material. Aluminum and copper form soft, rolled burrs; 300-series stainless, Nitronic 50, Inconel, Monel, Hastelloy, and titanium form tough burrs that resist removal; brass, bronze, and free-machining steels tend to form small, brittle burrs. Engineered plastics can leave fuzzy or stringy edges. We adjust tooling and deburring methods to the material in each job. See our materials page.
Deburring before plating, anodizing, and passivation
Finishes applied by outside processors follow every edge on the part. A burr left under anodize or plating becomes a coated burr that is harder to remove and may flake later. For that reason, we complete deburring and edge breaks before parts leave for any finish, and we inspect edges again when parts return. Details on how we manage finishing vendors are on our outside processing management page.
Quantity fit
Deburring is included in every quote from one-piece prototypes to production runs. For production, in-machine chamfering keeps bench time predictable, and deburring steps are written into the job router so every part in a lot gets the same treatment on every shift.
Inspection deliverables
Edge conditions are inspected visually and with magnification, and critical chamfers are measured on the Mitsubishi optical comparator. Deburring is part of our ISO 9001:2015-aligned process, and final inspection records are kept with the job. CMM reports, AS9102-format first articles, and material certifications are available.
