Large Part CNC Machining

Napoleon Machine is a world-class, large part CNC machining provider. We have served some of the most iconic names in the industry, a testament to our abilities. We can produce parts up to 48 feet (14.63 meters) on the (x) axis by 16 feet (4.88 meters) on the (y) axis. Regarding weight, we can handle parts up to 65,000 lbs.

To achieve world-class recognition, it helps to have state-of-the-art equipment. Therefore, we have made investments in modular fixturing and shrink-fit tooling. Also, we employ automated probing, advanced tooling, and the latest in CNC programming software.

While state-of-the-art equipment is essential, having skilled tradesmen is vital. Our team of expert machinists has hundreds of years of combined experience with large part CNC machining. Should an issue arise with a machine print, our team will likely catch it on the front end. This type of proactive, expert service has saved our customers a lot of time and money.

We care about our customers and commitments, and producing a quality product separates us from many competitors. If you have a large part CNC machining project coming up, reach out and chat with us. Email or schedule a meeting. Be sure to check out our large part welding services before you leave.

Quality built into every process.

Properly inspecting parts is an important aspect of our business. However, if you are catching errors in the inspection process, it is too late. There are expenses associated with rework, and often errors cause late deliveries. This is why we build quality into every process. For example, we have kickoff meetings for each job. Our welders, machinists, programmers, project managers, and painters meet and review prints in close detail and iron out any issues on the front end. We have invested in modular fixtures, shrink fit tooling, pre-setters, automated probing software, and more.  All of these tools help to ensure quality in manufacturing.

Inspection Tools:

  • FARO Laser Tracker
  • FARO Gage
  • CMM (Third-Party)
  • Mitutoyo Gages

Large Part Setup on Modular CNC Machining Fixtures

When most people think about repeat production and modular fixtures, they think of small parts. However, we are breaking the mold for large part machining using the same tools that small part production shops use but on a bigger scale. Tools like magnetic fixtures and modular sub-tables are just a couple of ways we cut time and cost out of large part machining.

Do we have the certifications needed to work on your large part CNC machining project?

“First order was on time. Inspection report was well done. Part was physically inspected by us and looked excellent. All in all, I would give you a grade of an A. Keep up the good work and we will be sending you more RFQ’s when we have large parts to be machined or fabricated.”

Are short lead times important to you?

Our scheduling tool sends out lead time notices when a machine or department gets low on work.  This allows our customers to take advantage of cheaper rates and faster turn-around.
