CNC Milling in Ogden, UT
CNC machining is the most common subtractive manufacturing technology and a hugely flexible and robust method for producing custom metal and plastic parts. Converting 3D models into G-code, CNC machines remove material from a solid block with various cutting tools. The most popular type of CNC machining is CNC milling, which combines the same computer numerical control (CNC) with a multi-point cutting tool or milling cutter to produce parts with tight tolerances and impressive mechanical and material properties. CNC milling, available in 3-, 4- and 5-axis machines, involves mounting a workpiece to a machine bed and letting automated tools do the rest. It’s ideal for complex design, being one of the most accurate manufacturing techniques on the market. Engineers turn to CNC milling for a huge range of applications, including parts for the aerospace, automotive, consumer electronics and medical technology industries, as well as prototypes and models. While 3D printing offers more design freedom, CNC machining outclasses most additive technologies for low- to medium-volume production, especially with the material range including aluminum, bronze, copper, steel and other engineering metals and polymers.
CNC Turning in Ogden, UT
CNC turning is another popular type of CNC machining, which uses state-of-the-art lathes and turning centers to produce complex, robust custom metal and plastic parts. Using CNC lathes and turning centers, our manufacturing partners can provide cost-efficient parts with simpler geometries. Live tooling is available for more complex geometries and is assessed on a case-by-case basis. Experienced operators use CNC turning machines for operations including parting, boring, facing, drilling, grooving and knurling, in contrast to how CNC milling machines are used. In general, CNC turning is a more affordable alternative to CNC milling and can outspeed milling in cases where the cutting tool’s range of motion is a mitigating factor. It’s important to note that CNC turning isn’t optimal for material conversation, but this is often a necessary trade-in for speed and price. Thanks to the high speed of turning tools, parts will have a lower roughness than milled components.
CNC surface finishing in Ogden, UT
CNC machining is an ideal process for producing custom parts with tight tolerances and high levels of precision. The only potential downside is that CNC parts often require post-processing to erase tool marks and improve their surface finishes for cosmetic and functional purposes. Applying the right surface finishes can improve your part’s surface roughness, cosmetic and visual properties, wear and corrosion resistance and a lot more. Protolabs Network offers a wide range of surface finishing options, including smooth and fine machining, anodizing, polishing, bead blasting, brushing, black oxide, chromate conversion coating, electroless nickel plating and powder coating, as well as many other more specialized post-processing methods for niche industry applications. Every surface finish has its advantages and drawbacks, so choosing the right one depends on several factors. It’s important to evaluate how your part will be used and in what kind of environment to make the best determination. You can choose from a variety of surface finishes in Protolabs Network's quote builder and contact networksales@protolabs.com for more information.

FAQ's about CNC machining service
What tolerance standards do you guarantee?
We guarantee that our manufacturing partners follow ISO 2768 standards for all CNC machined parts. Parts machined with metal will follow ISO 2768-m (medium) or ISO 2768-f (fine). Parts machined with plastics will follow 2768-m (medium). Geometric tolerances down to ± 0004 in. (0.010 mm) are possible but must be clearly indicated in technical drawings. We can achieve tighter tolerances on shafts with up to H7 fits with manual quoting and on occasion tighter.
Read more about our standards for tolerances here
What are the minimum and maximum dimensions you can machine?
At Protolabs Network we offer CNC milling (3-axis, 3+2-axis and 5-axis) and turning. Milled parts can be machined up to 2000 x 1500 x 200 mm (78.7 x 59.0 x 7.8 in.) for 3/3+2 axis CNC milling. For 5-axis milling, the maximum part size is 650 x 650 x 300 mm (25.5 x 25.5 x 11.8 in.). The maximum diameter for CNC turning is 431mm (17 in.), length 990 mm (39 in). Minimum part dimensions recommended are around 0.39 x 0.39 x 0.39 in. (10 x 10 x 10mm).The minimum for feature dimensions is 0.5 mm.
We are limited to a 1000 mm (39 in.) maximum size for parts on our platform. If you need higher dimensions, you can place the request through your account manager.
What cosmetic standards do you guarantee?
Deburring and edge breaking are standard procedures for all CNC machined parts. If there are any critical edges that should be left sharp, they must be clearly indicated in technical drawings. Surfaces will be free of defects such as scratches, dents, stains, blemishes, hanging marks, minor defects. Surfaces indicated as critical (primary (a) side, as indicated on the technical drawing) will be free of mill steps and other marks. For the secondary (b) side, minor hanging marks and up to 2 minor defects are acceptable. A number of post-processing and finishing methods can be applied to improve the surface roughness, visual properties and wear resistance of machined parts.
How much does your CNC machining service cost?
We use machine learning algorithms to calculate the exact cost of any machinable part directly from a CAD file, based on millions of CNC machining orders we’ve previously processed. No more waiting for technicians to get back to you via email, we can generate an exact quote for you instantly (well, in about 5 seconds).
This means you always know the price up front. Simply upload a CAD file to generate a quote: get an instant CNC machining quote. Our quotes are completely free, you only need to create an account so we can protect your IP.
It’s so easy to use that we encourage mechanical engineers to use it constantly as they optimize their designs for cost. Whenever you’ve made a new design iteration, simply load both the old and the new design into our quoting tool and see if the price is different.
This technology means our manufacturing partners also don’t need to do their own machining quotes, which means less overhead for them. This makes the whole process less expensive, which translates into lower prices for our customers.
How can I reduce the cost of my machined parts?
The main costs associated with CNC machining can be grouped into machining time, start-up costs, material costs, and feature costs. To reduce costs you need to understand the impact of these factors on cost.
The best way to reduce machining time is to design features that can be machined quickly, for example by choosing the correct radii for internal corners, reducing cavity depth, increasing wall thicknesses, limiting thread length and designing holes with standard sizes.
Material costs can be reduced by considering the size of the blank required, and the cost and machinability of the bulk material (softer alloys are faster to machine).
Start-up costs can be reduced by reducing the number part rotations or repositioning required to finish the part, for example by separating geometries into multiple parts that can be assembled later.
Feature costs can be reduced by only using tolerances when strictly necessary, removing all text & lettering, and avoiding multiple surface finishes.
These tips can be read in more detail in our full guide to reducing the cost of CNC machined parts.
How do you select the exact manufacturer for my parts?
We use algorithms to identify the best manufacturer in our network for your specific order, based on their proximity to you, their experience with similar parts and their available capacity right now. This allows us to balance our customers’ demands for speed, cost and quality better than ever before.
Where can I learn more about CNC machining?
Protolabs Network was started by mechanical engineers and we have many more engineers and technicians in our team. Together we’ve written a lot of content on CNC machining over the years. You can find a selection of resources below, or you can head to our knowledge hub and filter on CNC machining to read case studies, in-depth design guidelines and explanations of different surface finishes.
We’ve also written a complete engineering guide to CNC machining. Here you can learn about how the many different kinds of mills and lathes work and the different materials available, so you can easily compare their benefits & limitations. You’ll also learn the basic design rules for machining and the most common applications of each material and surface finish, so you can make the right choices every time.
Should I choose local or global manufacturing?
Customers in the US and EU can choose local or global manufacturing for CNC machined parts. Local orders are manufactured within your customs-clearance zones, allowing for shorter lead times (from 5 days) and faster delivery as there’s no need for shipments to clear customs. Global orders generally result in longer lead times at a lower price. The best option depends on the timeline and requirements of your project.
