Machining Capabilities
At Advance Bronze Inc., we continually enhance our machining capabilities by integrating the latest technology. Our extensive array includes more than 25 computer numerical controlled (CNC) machines and a selection of over 20 manual machines such as turret lathes, vertical mills, and horizontal mills. With various multi-axis machines, which encompass the latest technologies, we have reduced operations needed to produce finished bronze components. The technology improvements have lowered cycle times and had helped reduce costs for our customers. Implementing CAD/CAM software has streamlined our production process allowing us to produce more complex bronze components.
These resources enable us to offer a wide range of capabilities, allowing us to manufacture parts for our customers ranging from 1″ to 100″ in diameter and up to 60″ in length.
Custom Features & Groove Patterns
Advance Bronze is equipped with comprehensive range of machinery for drilling, countersinking, counterboring, and thread cutting, capable of handling both standard and custom oil groove configurations. We specialize in producing self-lubricated and graphited bearings, available in configurations such as plugged or grooved, tailored to meet specific application requirements.
Wear Plates Capabilities:
At Advance Bronze in addition to centrifugal castings, we have the abilities to produce machined bronze liners and bronze wear plates for numerous industries. Our capabilities include but are not limited to 36″ wide X 100″ long in various thicknessses. Parallel and flatness tolerance can be held within .001″. Diverse oil groove patterns can be produced, alternatively we can provide graphite lubricated liners/wear plates.
We specialize in producing a variety of bronze components including bushings, thrust washers, spacers, seal rings, wear plates, liners, and gibs. These components are economically cast in thickness from fractions of an inch to several inches and are meticulously machined to precise shapes and sizes, holding tolerances as tight as .001″.
Our commitment to innovation and extensive machining capabilities ensures that we can meet the diverse needs of our customers with precision and efficiency.

Machine List:
Most of our CNC lathes are considered multi-tasking centers with simultaneous 4-axis turning using both turrets at the same time to reduce cycle time in improve productivity. Our machines have an added C-axis and Y-axis to include mill features such as holes, grooves, drilled and tapped holes, and slots. This reduces multiple setups and increases our efficiency.
Okuma CNC
(mutli-tasking machines with the ability to turn and mill in multiple axis)
This machine increased efficiency in ways such as:
- Simultaneous 4-axis turning with 2 turrets improves productivity and reduces cycle time.
- 20 tools on 2 turrets make permanent tooling possible and reduce set-up times.
- One turret is equipped with a receiving shaft, tray, etc to receive the work piece on cutoff and carry it to the take off position with the rotation of the turret.
The quality of the product can also be improved in ways such as:
- Work piece is supported by follow rest on one turret, making chatter-free turning of even long work pieces or long cantilever work pieces possible.
- Simultaneous turning programs for facing of chamfering prevent burrs for improved part quality.
- Balanced cutting from both turrets for chatter-free turning impossible with 2-axis cutting.
VTL
(vertical turret lathe)
Increased capacity capable of the following:
- Max swing diameter: 63"
- Max turning height: 50"
- Spindle Speed: 3-300 rpm
- Tool live spindle
- Max turning diameter: 63"
- Table Diameter: 50"
- ATC: 16 Positions
