About AMT

Machining parts in Iowa since 1959.


Quote it straight. Machine it right. Ship it on time. We started as a manual mill and lathe shop and grew into a full CNC operation, all under one roof in Johnston, just north of Des Moines. The tools changed. The habits did not.

Our story

From manual machines to full CNC.

Advance Machine Technologies has machined parts for businesses since 1959.

We began with manual mills and lathes. Today the floor runs CNC mills, CNC lathes, waterjet cutting, bending, and welding, so a part can be cut, machined, welded, and finished without leaving the building.

From one-off prototypes to production runs, your parts get the attention and level of service you expect. That has not changed in more than sixty years.
