4-Axis CNC Machining Solutions

Miller CNC Offers 4-Axis Milling Services to Meet Your Industry Needs

As a more efficient alternative to 3-axis milling, 4-axis CNC milling provides increased production effectiveness while producing consistent, high-quality precision machined components.

With over a decade of hard metal machining expertise, Miller CNC has cultivated a manufacturing process that focuses on technology, efficiency, and exceptional attention to detail. Our ASD9100 and ISO 9001:2015-certified machining processes allow us to mill components for mission-critical applications. We leverage our state-of-the-art milling equipment with advanced CAM software, which allows us to create complex components more quickly than our competitors.

Precision 4-Axis Milling Advantages

The primary difference between 3-axis milling and 4-axis milling is an increased complexity of the movements that can be performed relative to the workpiece and the cutting tool. With the ability to produce more complex shapes than a 3-axis milling center (features around the perimeter of a part), 4-axis milling often utilizes shorter cutting tools that equates to better surface quality.

Another key advantage to 4-axis milling is the capability of the 4-axis mill to machine higher volumes than a 3-axis mill. 4-axis milling allows for increased volume due to holding multiple parts in one fixture while hitting multiple sides of that part in a single setup. 3-axis machines are typically used for machining components with a 2D geometry. 4-axis machining adds a rotation about the X-axis and utilizes a spindle with 3 linear axes of movement with the added capability of rotating the fixture in the A-axis. This allows 4 sides of a part to be machined from a single fixture setup.

High-Quality 4-Axis Milling Expertise

Miller CNC has the aerospace and military component expertise to produce high-quality, performance-based machined components. Our 4-axis milling machine centers can efficiently machine your component with ease. Our planning and engineering processes include multi-step development plans, inspections, and quality control measures to ensure complete product conformance.

CNC Milling For Multiple Applications

As an AS9100D certified manufacturer, Miller CNC has been a trusted with government and defense contracts for more than a decade. In addition to the Aerospace and Military and Defense industry, we are capable of creating performance-built components for a variety of industries including:

4-Axis Machine Capabilities

With an easy setup and flexible processing, 4-axis milling is perfect for components that require greater flexibility and cutting angles than a 3-axis milling center can accommodate. One of the primary advantages of 4-axis machining is the ability to cut features along an arc to create curved components. Additionally, 4-axis milling can be used for secondary operations on parts that come off of our lathes. The added axis allows for simultaneous movement and rotation for increased accessibility.

CNC Milling Components

4-axis machining allows us to create machine-angled features that are otherwise not possible with 3-axis CNC machining. Index and continuous 4-axis machining is available depending on the component design and requirements. Some component examples include:

  • Aerospace Components
  • Cam Lobes
  • Helixes

4-Axis Machining Materials Used

We specialize in hard metals and exotic alloys, and can create mission critical components that hold up to demanding environments. We have experience forming complex parts from multiple materials, including:

Additional CNC Machining Services

While we have a range of milling machines from 3-axis4-axis, and 5-axis milling capabilities, it is important to understand which process can optimize your component. Typical projects include CNC milling components up to 40 inches in length and milling parts within our multiple 18” diameter x 20” length turning centers. Our sourced hardware meets MIL-Spec, AMS-Spec, AN-Spec and other regulatory requirements, and our ISO 9001:2015-certified manufacturing processes allow us to create performance-critical components for industries with strict regulations.
