Comprehensive CNC Machine Services

We strive to be your choice for metal machining by offering the ability to order almost all parts for one product from a single, reliable provider. We operate CNC mills, lathes, vertical machine centers and turning centers and our CNC machines include brands like Bardons & Oliver, Mazak, Doosan, OKK, Okuma, Haas and Mori Seiki. Industries that benefit from our custom CNC machining services include aerospace, energy, government/defense, medical, processing and manufacturing.

Summit Steel & Manufacturing’s combination of software, automatic tool chargers and multiple-axis capabilities helps to minimize setups in the CNC production machining process and provide customers with accuracy and competitive prices for all metal fabrication projects. We have manufactured parts for the agricultural equipment, recreational vehicle, consumer products, aerospace, construction and many other diverse industries, and we are committed to exceeding your expectations in precision manufacturing.

We offer CNC machining parts services for the following materials:

  • Aluminum
  • Brass
  • Carbon steel
  • Castings
  • Plastics
  • Stainless steel
  • Titanium


We offer exceptional milling and turning capabilities. From pre-production prototypes to custom tooling and gauging, our experienced team will work with yours to manufacture CNC machined parts that provide the perfect fit for your equipment and applications.

Why is custom metal machining preferable to standard metal machining services? CNC custom machining services allow us to create your metal parts with a level of precision that standard machines cannot match. In industries such as the medical arena, aerospace, defense and many others, even slight errors or imperfections can have disastrous consequences.

With Summit Steel, you can be assured that our CNC manufacturing services will deliver your parts with the small margins of error you need. You will also get them on time, even when you need a high volume of CNC machining work.


CNC Machining, or computer-numerical control machining, is a partially automated method of machining parts that has a number of advantages over conventional machining. By using CNC to operate machine tools like lathes, mills and grinders, we can produce a very high level of precision accurately and consistently when fabricating metal parts.

The CNC machine also allows us to control multiple machines with a single human operator, increasing speed and productivity without losing quality. If you have high-volume metal fabrication needs, our CNC precision metal machining is the best way to produce even complex parts efficiently enough to meet your timelines. In fact, CNC machining allows us to manufacture CNC custom parts with even more complex designs than is possible through conventional methods.


CNC machining applications cut across a wide range of industries. Any company that needs accurate, consistent, sometimes complex shapes when it comes to metal parts can benefit from CNC machining services. We welcome CNC machining projects from industries such as:

  • Aerospace and defense – Parts for fixed-wing aircraft, helicopters, flight safety parts and various other spare parts
  • Agriculture – A variety of parts including those for farming equipment and farm vehicles
  • Automotive – Various metal car parts, motorcycle parts and related accessories
  • Construction – Support beams, heavy construction equipment and more
  • Firearms – Parts for small arms as well as larger ballistic devices
  • Electronics – Many parts, including electronics housings and enclosures and semiconductor parts
  • General manufacturing – Fabrication of virtually any metal part required for your manufacturing processes
  • Publishing – Various publishing machines and equipment
  • And many more


We can effortlessly provide stainless steel CNC machining services, aluminum CNC machining services and precision CNC machining services for complex shapes and parts. Our CNC machining process is state-of-the-art, so if there is any project or industry you’re not sure we can handle, give us a try and find out. We’re confident you will be satisfied with the results.


It is impossible to dispute the benefits of working with a contract manufacturer for all of your metal fabrication work. We already have the top-of-the-line CNC machines in our facility that are required to do quality machine work. You would have to go out and buy them.

Even if you decided to make such an expenditure, you wouldn’t necessarily know the correct machines to get. You also probably would not have the time or expertise we do to make sure they are always properly maintained so that they work at peak efficiency all the time.

You would then have to train operators to work those machines — operators who might already have important responsibilities in your business. You would have to adjust your infrastructure to accommodate your metal working arrangements, and once you’ve done all that, you might not leave yourself any room to grow.

When you contract out your metal working to us, you have access to a partner with all the infrastructure, skilled personnel and equipment already in place. All you have to do is tell us what you need and when you need it. We can do it all in-house, quickly and at an affordable rate. Our experience, machine quality, facility dedicated entirely to metalworking and our single, local location makes us the most cost-effective solution for any industry that needs metalwork done.

Whether you are already doing your own metalwork or are just considering it, try Summit Steel now and find out just how streamlined the entire process can really be.
