Built for the Machining Projects Others Avoid
Premier Industrial Group is a full-service CNC machine shop serving manufacturers that require precision parts, complex geometries, large machined components, specialty materials, and low-to-mid-volume production support. We are especially effective when projects involve tight tolerances, demanding delivery schedules, or parts that must integrate with fabricated assemblies, repaired equipment, or field-installed systems.
Our precision machining capabilities support prototyping, replacement parts, short runs, low-to-mid-volume production, and large custom components. Whether the need is a single critical replacement part or a repeat production requirement, we focus on quality execution, clear communication, and reliable turnaround.
Engineering-Led Precision Machining
Many machine shops simply build what they are given. Premier Industrial Group takes a different approach. Our in-house engineering support helps customers solve machining challenges before they become production problems. We help evaluate manufacturability, review tolerances, improve process flow, and address fit-up, alignment, clearance, and material concerns early in the project.
That engineering-led approach is especially valuable when parts are difficult to machine, documentation is incomplete, or the work must tie into fabrication, equipment repair, or field installation. By integrating engineering with machining execution, we reduce risk, shorten lead times, and improve outcomes.
CNC Turning & Milling
Our CNC turning and milling capabilities support complex components requiring dimensional accuracy, repeatability, and efficient multi-operation machining. We use advanced CNC lathes and mills to reduce setups, improve consistency, and machine complicated geometries more efficiently.
We routinely machine plastics, aluminum, copper, stainless steel, and demanding alloys such as Inconel, Hastelloy, and molybdenum. With OD turning capacity up to 38 inches, we are equipped to support both conventional industrial components and larger, more specialized parts.


Wire EDM Machining
Premier Industrial Group provides multi-axis wire EDM machining for parts that require intricate shapes, sharp inside corners, thin-wall features, and precise cuts that are difficult or impossible to achieve through conventional machining. Wire EDM is ideal for tooling, dies, molds, fixtures, and high-precision components where detail and accuracy are critical.
Surface Grinding
Our large-format surface grinding capability allows us to produce parts with excellent flatness, parallelism, and fine surface finishes. We can support both smaller precision components and larger oversized parts that require controlled finishing and exact dimensional performance. This process is especially valuable when machined components require improved surface quality, final fit, or close-tolerance finishing.


Large-Part and Bridge Machining
Large-part machining is one of our core strengths. Premier Industrial Group supports customers who need heavy, oversized, and safety-critical machined components that many shops simply cannot handle efficiently.
