5 Pallet, 5 axis

2 pallet 5 axis

Horizontal Mill

These state-of-the-art 5 axis vertical mills are considered by many to be the best in the industry. With these mills Marathon is able to produce parts of very high quality and unprecedented accuracy. 

Our Matsuura mills include a palletized system for continuous, around the clock, operation.

Sodick High Speed Mills

This extremely accurate high speed mill is ideal for high tolerance parts.

Electric Discharge Machining (EDM), Wire 

To find a machine shop with one wire EDM can be challenging....Marathon has 3 EDM machines! This gives Marathon the flexibility to handle a wide range of parts and materials. 

EDM machining is extremely accurate and it can handle even the hardest materials. Ideal for high tolerance features, splines, and keyways.   

Electric Discharge Machining (EDM), Sinker 

Instead of a wire the sinker EDM uses a carbide electrode that is milled to a specific shape then plunged into the work piece to remove material.

The sinker EDM is extremely accurate and can cut into even the hardest material with a fine surface finish.

Ideal for difficult, high tolerance, features.

Lathe Department 

Mazak - 2, 3. Axis Lathes

Mazak Integrex Lathes

Manual Lathes

With several CNC and manual lathes, Marathon can handle most turned parts both small and large.

Marathon is also production ready with bar feeders and live tooling.

Grind department 

Okamoto O.D. Grinders

Okamoto Surface Grinders

Blanchard Grinders

Marathon operates OD, surface, and Blanchard grinders.

All OD grinding is on CNC machines for the highest tolerance and best surface finish.

Weld & Fabrication 

Marathon is also a very capable weld and fabrication shop. 

Parts requiring welding and a secondary machining process to complete is something Marathon excels at.

Waterjet & Laser
