Advanced CNC Control

Computer-controlled rotary positioning and coordinated toolpaths provide precise angular positioning, repeatable machining, and efficient production of complex component geometries.

What Is 4-Axis CNC Machining?

4-axis CNC machining is a subtractive manufacturing process that adds a rotary axis to the three linear X, Y, and Z axes used in conventional CNC milling. The additional rotary axis allows the workpiece or cutting tool to rotate during machining, providing access to multiple sides and features of a component without manually repositioning the part.

This additional axis makes 4-axis CNC machining particularly effective for components with features positioned around a central axis, angled surfaces, multiple side features, and complex profiles that would require several setups on a 3-axis machine.

4-Axis CNC Machining Capabilities

TFG’s 4-axis CNC machining services provide increased flexibility for production components with multiple machining surfaces and complex geometries.

  • Multi-Sided Machining: Machine features on multiple sides of a component with fewer manual setups.
  • Rotary-Axis Machining: Continuously or indexed rotary positioning provides access to features around the circumference of a part.
  • Complex Contouring: Coordinated axis movement enables machining of curved, angled, and contoured surfaces.
  • Drilling & Tapping: Accurately machine holes and threaded features at multiple orientations.
  • Pocketing & Profiling: Produce recessed features, slots, profiles, and other precision-machined geometries.
  • Reduced Setups: Minimize workpiece repositioning to improve consistency and reduce production time.

4-Axis CNC Machining Materials

TFG machines a broad range of metals depending on the application, part geometry, production requirements, and material specifications.

  • Aluminum: Lightweight, corrosion-resistant, and highly machinable for housings, brackets, covers, fixtures, and industrial components.
  • Stainless Steel: Provides strength and corrosion resistance for components used in demanding operating environments.
  • Carbon & Alloy Steel: Selected for applications requiring strength, hardness, wear resistance, and durability.
  • Brass & Copper: Offer excellent machinability and conductivity for electrical, industrial, plumbing, and mechanical components.
  • Titanium: Combines high strength, low weight, and corrosion resistance for demanding applications.
  • Specialty Metals: TFG can support machining of specialty alloys based on project requirements, including high-strength and corrosion-resistant materials.

The Federal Group is a top-notch supplier of ours. They take quality very seriously and strive to ensure we have exactly what we want and when we need it. Communication is excellent. Service is excellent. I have worked with this supplier directly for better than 7 years now, and still considered one of my best suppliers. We've recently expanded our product line with this company and are excited to partner on this line and on future projects. Words cannot express how grateful I am to have such a responsive company, and rep, Richard, to work with. I highly recommend this supplier.
