At Northern Iron & Machine, our machinists are highly trained experts capable of machining everything we cast in iron.
We are especially skilled at machining larger parts in the difficult 50 to 250-pound iron casting range. We utilize more than 14 CNC machines including Horizontal, Vertical, Turning, and Automated Systems with hydraulic fixturing.
See examples of our machining work and you’ll see firsthand the level of machining capability Northern Iron & Machine can accomplish for you.
Our machinists work on some of the most precise machining equipment available: four axis, fully programmable CNC machines capable of machining to tolerances of ±0.0005 in. Please check our machine shop facilities list below to see our complete line of CNC Turning and CNC Milling equipment.
To ensure the greatest possible precision, we check dimensions on our automated CMM’s throughout each shift and perform a final inspection before parts are shipped. Our production, engineering, and quality team members work together to design and maintain robust processes. These processes enable us to provide a quality product at a competitive price.
Each of our CMM’s operate with a volumetric accuracy of 8 microns.
The measurement data that’s collected when a part is inspected on the CMM, is relayed to our Statistical Process Control software.
This Statistical Process Control software allows us to monitor the machining processes. We strive to maintain stable processes that have a Cpk of 1.33 or better.
We also have a full range of manual inspection equipment that we use to ensure that dimensions are within the tolerances specified by our customers.
As part of our comprehensive quality system, we have our machine operators measure various dimensional features with manual gauging during the machining process.
This provides us with a greater sampling frequency for critical dimensions. Each operator has a computer at his workstation where these manual measurements are recorded
as part of our quality records.
All of our measurement equipment is monitored by an internal calibration system that is traceable back to NIST standards.
The machine shop carries the same ISO 9001 accreditation as the foundry.
