High-speed milling for valves, gear housings, and cosmetic faces. Balanced holders and light finish passes deliver bright surfaces ready for sealing or plating where required.
Fast, repeatable turning for bushings, sleeves, and bearing components. Mill-turn one-setup keeps concentricity tight and improves surface finish across features.

From free-cutting bearing bronzes to tough aluminum bronzes for high-load applications.
High SFM with sharp tools; chip-breakers help control stringers on lathes.
Moderate SFM with firm feed; use coated carbide and steady chip evacuation.
Use sharp edges and short stick-out; plan a light finish pass for flatness.
Lower SFM, strong chip load, coated carbide; consider stress relief on large parts.
Material Machining Guide
Bronze is commonly considered for bushings, bearings, wear parts, marine components, and sliding surfaces. It is selected because of wear resistance, low friction, and corrosion resistance. For CNC machining, the final result depends on material grade, toolpath strategy, tolerance allocation, surface finish, and inspection planning.
Use Bronze when the application benefits from wear resistance, low friction, and corrosion resistance and the design can be machined with stable workholding.
Confirm wall thickness, hole depth, thread callouts, burr control, cosmetic surfaces, and finish buildup before production.
Define critical dimensions, inspection method, tolerance class, and documentation requirements before the first article.
| Topic | Practical Guidance for Bronze |
|---|---|
| Design review | Send 3D CAD, 2D drawings, material grade, finish notes, quantity, and critical-to-function dimensions. |
| Machining process | MTSPi can review whether milling, turning, drilling, tapping, boring, or a combined route is best for the geometry. |
| Surface finish | Plan cosmetic and functional finishing early, especially where coating thickness, polishing, or deburring affects fit. |
| Inspection | Use calipers, micrometers, gauges, CMM, or visual inspection based on tolerance risk and assembly function. |

FAQ
Yes, Bronze can be CNC machined when the grade, geometry, tooling, workholding, and tolerance requirements are planned correctly.
Send CAD files, 2D drawings, quantity, material grade, finish requirements, tolerance notes, and any inspection or packaging needs.
Often yes. The right finish depends on the material family and part function. Confirm finish thickness and cosmetic expectations before machining.
Use practical tolerances, avoid unnecessary deep pockets or tiny holes, simplify setups, and reserve tight control for functional features.
