CNC Milling Services
Dynamic Design & Manufacturing offers precision CNC milling services for process control instrumentation, medical devices, telecommunications, aerospace, and national defense applications.
From our 31,000 sq. ft. shop in Niwot, Colorado, we machine prototype and production parts for clients across the Front Range and around the world. Our CNC milling operation in Colorado is staffed by an engineering team that works alongside customers to refine designs for manufacturability, and a production team that meets the tolerances those designs require. Every part we machine is backed by an AS9100D and ISO 9001:2015-certified quality management system, and our ITAR registration with the U.S. Department of State means we are cleared to produce components for defense programs.
Precision CNC Milling for Demanding Tolerances
Tight tolerances are the baseline for the industries we serve. Our Mori Seiki NV5000 α1 machining center holds volumetric accuracy to ±0.00018", giving customers the dimensional confidence required for flight hardware, medical instruments, and sensor housings. Repeatability across long production runs is one of the reasons OEMs consolidate their precision CNC milling work with DyCo rather than splitting it across multiple vendors.
Our CNC milling machine services cover the full range of operations customers expect from a precision shop, including drilling, boring, contouring, surfacing, and complex profile work on both simple and intricate geometries. We machine parts in stainless steel, carbon steel, aluminum, nickel alloys, and titanium alloys, along with engineered plastics such as Nylon, Acetal, and Delrin.
CNC Milling Equipment
Our shop floor is constructed around late-model machining centers selected to give customers the right tool for the job, whether that is a single complex 5-axis part or a high-volume run of mid-sized components.
5-Axis CNC Milling Services
Our 5-axis CNC milling services are anchored by a DMG MORI NTX 1000 Mill-Turn. The machine performs simultaneous 5-axis work using a direct drive motor on the B axis, with 240 degrees of B-axis rotation and spindle speeds up to 12,000 RPM. For customers with complex geometries that would otherwise require multiple setups across multiple machines, the NTX 1000 holds the part in a single fixture and finishes it in a single operation, protecting tolerance stack-up and shortening lead times.
3-Axis CNC Milling
For production work where part geometry suits a 3-axis approach, we run two dedicated vertical machining centers. The Atrump VH1000 offers 40.1" x 20" x 22" of travel, and the Fadal VMC 40 offers 22" x 16" x 20". Both are ideal for mid- to high-volume runs where accuracy, surface finish, and cycle time consistency matter.
Large-Capacity Milling
When parts grow past the envelope of a standard VMC, we move the work to our DMG Mori CMX 1100 V. The machine accepts workpieces up to 55.1" long and 2,204.6 lbs, giving customers in-house access to large-part precision CNC milling without needing to qualify a second vendor for oversized components.

CNC Milling and Turning Services in One Workflow
Many of the parts our customers design require both milled features and turned features. Rather than transferring those jobs between separate mills and lathes, we run CNC milling and turning services on the same DMG MORI NTX 1000 platform. The mill-turn approach combines turning operations and full simultaneous 5-axis milling within a single setup, eliminating the inspection-and-refixture cycle that often introduces variation in multi-operation parts.
An Integrated Fabrication and Machining Shop
CNC milling rarely stands alone in the lifecycle of a part. Most of the components our customers order require a combination of processes, and our shop is laid out to handle the full progression in one building. Our milling cells connect directly to laser cutting, CNC punching, forming, rolling, welding, laser welding, and hardware installation.
A customer purchasing a milled housing can also have the brackets formed, the enclosure laser cut, the hardware pressed in, and the assembly finished and shipped without ever leaving our facility. This integrated workflow reduces inter-shop transit time, keeps the chain of custody intact for ITAR work, and gives a single point of accountability for the finished assembly.

From Prototype to Production
Our capacity covers the full lifecycle of a part. Early-stage customers come to us with a CAD drawing and need one or two prototypes machined and inspected before they commit to tooling. Established programs come to us with annual purchase orders for hundreds or thousands of pieces. Both are core to what we do, and the same engineering and production teams support both.
Our engineering staff reviews every incoming quote request and offers design-for-manufacturability feedback before the first chip is cut. This is often where the greatest cost savings are achieved on a precision part, and where the greatest quality is built in.

Frequently Asked Questions
Frequently Asked Questions About CNC Milling Services at DyCo
In 3-axis milling, the cutting tool moves along X, Y, and Z axes while the part stays fixed. This works well for most prismatic parts, flat features, holes, and pockets accessible from a single face. Five-axis milling adds rotation on two additional axes, which allows the tool to approach the part from nearly any angle in a single setup. If your part has undercuts, compound angles, curved surfaces, or features on multiple faces that need to relate precisely to one another, 5-axis is likely the better fit. We can review your drawing and tell you which process makes sense.
Yes. We mill titanium alloys and nickel alloys regularly for aerospace and defense customers. These materials require specific feeds, speeds, and tooling strategies due to their hardness and heat-generation characteristics. Our production team programs and tools each job specifically for the material, not generically. Our AS9100D quality system covers all inspection and documentation for aerospace-tolerance work.
Our DMG Mori CMX 1100 V handles workpieces up to 55.1 inches long, 22 inches wide, and 24.8 inches tall, with a maximum workpiece weight of 2,204.6 lbs. For large-format milling requirements in Colorado, this is one of the larger work envelopes available at a Front Range precision shop.
Yes. Our engineering staff reviews designs during the quoting process and will flag features that add unnecessary cost or risk during machining. This is especially useful for 5-axis or complex multi-feature parts where a small design change early in the process can save significant time and cost in production. There is no charge for this review as part of the quoting process.
Our Mori Seiki NV5000 α1 achieves a volumetric accuracy of ±0.00018 inches. Practically achievable tolerances on finished parts depend on the geometry, material, and specific feature being held. For tolerance-critical components, we recommend sharing your drawing early so our team can confirm what is achievable and identify any features that require special process planning.
Yes. We perform precision CNC machining on Nylon, Acetal, and Delrin in addition to our full metal material range. Plastic milling requires different tooling and fixturing strategies than metal work, both of which our production team manages as part of standard job planning.
Yes. While we are a Colorado CNC machine shop and work with many Front Range and Denver-area manufacturers, we ship parts nationally. Customers who need AS9100D and ITAR-compliant milling and cannot find a qualified local source frequently work with us remotely, submitting drawings electronically and receiving finished parts via freight.
Our CNC milling work spans aerospace, national defense, medical device, telecommunications, and process control instrumentation. Each of these industries has distinct documentation, certification, and traceability requirements, all of which our quality system is built to support.
We accept STEP, IGES, Parasolid, SolidWorks, and 2D PDF drawings. STEP files are preferred for 5-axis work because they preserve the geometry our programmers need without translation losses. If you only have a paper drawing or a sketch, send it along, and our engineering team will work with you to build out what we need.
There is no minimum. We routinely run prototype quantities of one or two pieces, and the same shop handles annual production orders in the thousands. Pricing scales with volume, of course, but our willingness to take a job does not.
Both. Mechanical finishing operations, including deburring, hardware installation, and assembly, happen on-site. For specialized coatings such as anodizing, plating, passivation, powder coating, and chromate conversion, we work with a vetted network of finishing partners and manage the routing as part of the order.
