CNC Machining

Precision CNC Machining in Flint, MI

Turn your prints into parts. Iron Mann Industries runs 3-axis CNC milling and turning to produce precision components for prototyping, production, and repair work. From a single one-off piece to a 5,000-part production run, we deliver tight tolerances with fast turnaround.

We’re a build-to-print machine shop. You provide the drawings, we provide the parts. No minimum orders, no long lead times, no middlemen sending your job overseas.

Prototyping and R&D

We work directly with engineers and product developers to turn CAD files into physical parts. When you’re in the development phase, speed and communication matter more than anything. You need a shop that machines your prototype fast, gives you honest feedback, and doesn’t make you wait behind a queue of production jobs.

• Rapid prototyping with quick turnaround on single parts
• Design for Manufacturing (DFM) feedback to help reduce costs before full production
• Iterative revisions as your design evolves
• Small-quantity test runs to validate fit, form, and function

If your prototype needs welding or fabrication work in addition to machining, we handle that in-house too. No coordinating between shops.

Production Runs

Need 50 parts? 500? 5,000? We’re set up for efficient short-run and medium-run production. Our CNC setup ensures every part comes out identical to the first, and our low overhead means competitive pricing on batch orders without cutting corners on quality.

• Small to medium batch manufacturing (50 to 5,000+ parts)
• Consistent tolerances across entire production runs
• Contract manufacturing support for local manufacturers
• Repeat order capability with stored programs and setups

Production Rework Services

Did another supplier mess up your order? Don’t scrap the whole lot. We specialize in production rework, which means we take parts that were manufactured out of spec and fix them so they meet your requirements.

This is one of those services most shops don’t advertise because it’s not glamorous work. But when you’re sitting on a pallet of parts that won’t pass inspection and your assembly line is waiting, it matters. We re-machine, re-drill, re-tap, or modify existing parts to bring them back into tolerance. We save your inventory and keep your production moving.

Replacement Parts and Reverse Engineering

When a machine goes down, you can’t always wait weeks for an OEM replacement. Sometimes the OEM doesn’t even exist anymore. We machine replacement parts in-house to get you back up and running. If you need broader machinery repair beyond just the machined component, we handle that too.

• Shaft repair: turning down worn shafts and sleeving them, or machining new ones from scratch
• Custom bushings: bronze, steel, or nylon bushings turned to fit worn bores
• Reverse engineering: we measure a broken part and machine an exact replica
• Obsolete component recreation when OEM parts are discontinued

Bring us the broken part. We’ll measure it, quote it, and get you a replacement. If the original part failed because of a design weakness, we’ll tell you that too.

Materials

We machine steel, aluminum, stainless steel, brass, bronze, and industrial plastics like Delrin and UHMW. If you’re not sure what material your part should be made from, we can advise based on the application, loads, and environment.

Equipment and Capabilities

Our shop runs 3-axis CNC mills and CNC lathes alongside manual equipment for jobs that don’t justify a full CNC setup. This combination gives us flexibility. Complex geometry goes on the CNC. Simple modifications and one-off repairs go on the manual machines. You’re not paying for CNC setup time on a job that doesn’t need it.

• 3-axis CNC milling
• CNC turning/lathe work
• Manual milling and turning
• Drilling, tapping, and threading
• Surface grinding

Because machining, welding, and fabrication are all under one roof, we can take on projects that require multiple processes without farming anything out. A part that needs to be machined and then welded into an assembly stays in our shop the entire time.

Who We Work With

We serve manufacturing plants, automotive suppliers, food processing facilities, industrial equipment operators, and product developers throughout Genesee County and Mid-Michigan. We also work with individual inventors and small businesses who need a reliable machine shop that doesn’t require a five-figure minimum order.

If you need parts machined to print, a broken component reverse engineered, or a bad batch reworked before your deadline, call us at (810) 407-7585. We’ll give you a straight answer on timeline, cost, and whether we’re the right shop for the job.

Your prints, our machines, no excuses. That’s the Iron Mann way.
