🏭 About AMMR

American Metal Manufacturing Resource Inc. (AMMR) is a precision machine shop in Pomona, California, specializing in complex rough and finish machining for demanding applications. Established in 2007, the company operates from a 15,000-square-foot manufacturing facility and supports customers across commercial and military aerospace, private space, satellite, power generation, medical, industrial, oil and transportation markets.

AMMR is particularly well equipped for large-diameter CNC turning. Its conventional CNC lathes and vertical turret lathes can accommodate components ranging from approximately 4 to 100 inches in outside diameter. The work includes complex, close-tolerance parts manufactured from challenging materials such as Inconel 625 and 718, Waspaloy, titanium, stainless steel and aluminum.

The shop supports projects from prototype development through ongoing production. Machinists work directly from detailed engineering drawings, establish and prove out setups, solve workholding challenges and inspect their own work throughout the machining process.

As an AS9100D-certified and ITAR-registered manufacturer, AMMR operates in an environment where process control, documentation and traceability matter. This is a shop for experienced machinists who understand that producing a conforming part requires more than simply running a program. Large workpieces, difficult materials and demanding customer requirements make setup knowledge, sound judgment and attention to detail essential.

👍 Why you’ll like working here

AMMR offers experienced machinists the opportunity to take real ownership of challenging work. Large-format turning requires careful planning, creative workholding, accurate indicating and a strong understanding of how the entire machining process fits together.

The work is well suited to machinists who enjoy solving problems and producing complex components rather than performing repetitive operator-only tasks. You may be involved from initial setup and program prove-out through in-process inspection and the final conforming part.

You will also gain exposure to demanding aerospace alloys, close tolerances and quality requirements governed by an AS9100D-certified system. Your experience with setups, tooling, offsets, inspection and troubleshooting will directly influence the success of each job.

For machinists who take pride in difficult work and want their skills to matter, AMMR provides the chance to contribute to aerospace, defense, space, power-generation and other critical manufacturing programs.

⚙️ What you’ll be working on

AMMR manufactures large, complex components for industries where precision, documentation and reliability are essential. Depending on the position, machinists may set up and operate CNC vertical turret lathes, indicate large-diameter workpieces, build or modify workholding and prove out programs at the control.

The work involves interpreting engineering drawings, GD&T requirements, datum structures and inspection criteria. Machinists may collaborate with programmers using Mastercam-generated code while making the control-level edits and process adjustments required to produce a conforming part.

Parts are manufactured from materials including titanium, Inconel, Waspaloy, stainless steel and aluminum. Machinists perform first-article and in-process inspections using equipment such as micrometers, bore gages, height gages and indicators.

This is hands-on precision machining in which setup quality, tooling decisions, dimensional control and troubleshooting ability all matter.
