CNC Milling Focused on Accuracy and Process Control

Successful CNC milling depends on more than machine capability. Part quality is driven by fixturing, tooling, cutting strategy, and inspection discipline.

At Mayfly Manufacturing, our milling approach emphasizes:

  • Stable, repeatable workholding
  • Tooling and toolpaths matched to material and geometry
  • Controlled climate
  • Consistent in-process inspection

This allows us to deliver reliable results across a wide range of part designs and materials.


CNC Milling Capabilities

We provide precision CNC milling for a variety of parts and applications.

Typical Capabilities

  • 3-axis CNC milling
  • 4-axis horizontal CNC milling
  • Precision pocketing, profiling, and drilling
  • Tight-tolerance features and critical surfaces
  • Fixture-based repeatability for production runs
  • Prototype through low–medium volume production
  • Secondary operations as required

Typical tolerances of ±.005” are common, with tighter tolerances possible depending on material and geometry.


Materials We CNC Mill

We machine a broad range of materials using CNC milling processes, including:

Metals

  • Aluminum
  • Stainless Steels
  • Mild Steels
  • Low-Alloy Steels

Plastics

  • Engineering plastics and wear-resistant polymers

Composite Materials

  • G10 / FR4 / G11 glass epoxy composites
  • G7 glass silicone composite
  • G9 glass melamine composite
  • Phenolic laminates
  • Carbon fiber composites

While we support many materials, we bring additional expertise when milling abrasive or laminated composite materials that require specialized tooling and strategies.


What Sets Our CNC Milling Apart

Process-Driven Machining

We focus on repeatable processes rather than one-off setups, resulting in more consistent parts, predictable lead times, and reduced scrap.

Material-Aware Milling

Different materials behave very differently under the cutter. Our experience allows us to choose cutting strategies that protect surface finish, edge quality, and dimensional stability.

Engineering-Focused Support

We regularly work directly with engineers to:

  • Improve part manufacturability
  • Optimize tolerances
  • Reduce machining time and cost
  • Prevent common machining issues

Reliable Manufacturing Partner

Purchasing teams value us for:

  • Clear communication
  • Honest feedback on feasibility
  • Predictable delivery
  • Consistent quality

Common CNC-Milled Applications

Our CNC milling services support components such as:

  • Precision plates, spacers, and blocks
  • Housings and structural components
  • Electrical insulation parts
  • Fixtures and tooling
  • Prototype and production assemblies

If your application requires precision, stability, and repeatable quality, CNC milling is often the right solution.


Design Tips for CNC Milling

Early design decisions can significantly impact part quality, lead time, and cost:

  • Avoid unnecessarily tight tolerances
  • Allow reasonable internal corner radii
  • Minimize deep, narrow pockets and holes where possible
  • Consider material behavior during design

We’re happy to review prints and provide feedback before machining begins.
