Precision CNC Milling for Complex Machined Parts

Our selection of CNC milling machines includes the following advanced CNC milling equipment:

3-Axis Milling

3-axis milling is ideal for milling simple parts, large parts or high-volume parts that can be produced at high levels of repeatability. This versatile milling process is designed for automatic operation and can hold multiple parts to cut in a single setup. Common pieces include square shapes, rectangular shapes and complex geometric shapes that can be held in a vise or custom fixture.

3-Axis Milling Equipment

  • Doosan, DNM-5700, 8K RPM, 40x20x25 machining center
  • Haas, VF3, 12K RPM, 40x20x25 machining center
  • Haas, VF2, 7500 RPM, 30x20x20 machining center

4-Axis Milling & CNC Lathes

4-Axis milling provides increased production effectiveness compared to 3-axis milling while still producing consistent, repeatable, high-quality precision machined components. The added axis allows for increased accessibility to create more complex shapes at higher speeds. This milling process is popular for creating complex aerospace and military components with a single setup. Additionally, 4-axis milling can be used for secondary operations on parts that come off of our lathes. 

4-Axis Milling Equipment

  • Haas, VF3, 12K RPM, 40x20x25 machining center
  • Haas, VF2, 7500 RPM, 30x20x20 machining center

5-Axis Milling

Our most advanced milling service, 5-axis CNC milling has become the standard milling option for manufacturing performance-built, complex components at high turnout rates. With our 5-axis CAM software with machine simulation, all features will be machined without physical handling of the part in one setup for faster, more cost-effective production. By milling a single component on multiple sides from a single fixture, 5-axis machining provides more accuracy than any other form of machining. Miller CNC can machine specialized components from hard metals and superalloys.

5-Axis Milling Equipment

  • Hermle, C400, 18k RPM 36x30x20 machining center
  • Hermle, C30, 18K RPM, 30x20x20 machining center
  • 2 Doosan, DNM-5AX, 12K RPM, 18x18x18 machining centers
  • Haas, VF2, 10K RPM, 30x20x20 machining center

Milling Software

Miller CNC builds and designs fixtures and performs CAM programming in-house. Our dedication to efficient process management includes documentation for all aspects of the job, from machining to QC to production cost control. When the time comes for a repeat production run, we can efficiently fulfill your order with a very quick change-over time.

Milling Software Programs

  • Hypermill 5-axis CAM software with machine simulation
  • Solidworks software
  • MasterCAM X10 software
  • PC-DMIS CAD++ software
  • Shoptech E2 ERP software

Miller CNC Superalloy Milling Advantages

With AS9100D and ISO 9001:2015 certifications, Miller CNC is your best source for high-quality, advanced, complex machined aerospace components. We specialize in working with exotic alloys and specialty metals that are difficult to machine. Our fully automated CNC machining capabilities allow us to optimize cycle time while performing all required machining processes in a single fixture. This saves on production time, as well as labor and setup costs.

Most of our production runs consist of short 10 to 50-part runs as well as medium-sized runs from 100 to 1,000 parts including LTAs.

Our state-of-the-art software provides machine simulation for reduced machine setup time and error-proofing. Program toolpaths are also optimized to ensure the lowest reliable cycle time as an added engineering process benefit to you.
