Machining Capabilities

Whether you need machining for a part weighing less than 20 pounds or expert, detailed machining for a large capacity part weighing 200,000 pounds, JMI has the technology, the expertise, and most of all, a passion for perfection on every job that ensures you will get exactly what you want, when you need it.

JMI has a variety of Bridge mills and horizontal boring mills allowing for redundant processes. If a machine goes down at JMI, we pride ourselves on being able to move that job to another machine without any issues.
