Prototype to high-volume production
We match each part to the right spindle. Complex aerospace housings go to 5-axis. Small precision turned parts run Swiss. High-volume fittings go multi-spindle. You get the cost and lead time of the right process, every time.
4-Axis Milling
Rotary indexing to reach multiple faces in one setup. Fewer setups, tighter feature-to-feature relationships.
- Receivers & housings
- Cross-holes, wrap features
- Tombstone production
5-Axis Milling
Simultaneous 5-axis for contoured surfaces, impellers and complex aerospace geometry in a single setup.
- Sculpted & compound angles
- Titanium, Inconel, 17-4
- Done-in-one machining
CNC Turning
Shafts, bushings and round parts, with live tooling for milled flats, cross-holes and threads in one cycle.
- Live-tool mill-turn
- Sub-spindle back-working
- Bar-fed production
Swiss Machining
Guide-bushing support for long, slender, small-diameter parts held to tight tolerances at production speed.
- Pins, screws, contacts
- Medical & firearm components
- Lights-out bar feeding
Multi-Spindle
When volume climbs into the hundreds of thousands, multi-spindle turning drives piece price down hard.
- Fittings, nuts, fasteners
- Brass, steel, aluminum
- Blanket-order releases

History
More than four decades of building it right
Marathon Technologies, Inc. was established in 1983 by an engineering and manufacturing team that already had 20 years of experience in design and manufacturing in the metalworking industry. Our manufacturing roots go back to the late 1970s.
Since then we have produced complex machined components and assemblies for the aircraft and defense industries, as well as automotive, fluid power, oil production and commercial manufacturing.
