3-AXIS & 4-AXIS CNC MACHINING

Precision Milling for Functional, Production-Ready Parts

CNC milling for housings, plates, brackets, fixtures and complex prismatic parts — from one-off prototypes to repeat production.

THE DIFFERENCE BETWEEN 3-AXIS & 4-AXIS

01 / STANDARD ACCESS

3-Axis CNC Machining

A practical and cost-effective solution for many prismatic parts where the required features can be accessed through standard machining setups.

  • Plates and flat components
  • Housings with accessible features
  • Pockets and cavities
  • Hole patterns
  • Parts reached through conventional machining directions

02 / ROTARY ACCESS

4-Axis CNC Machining

The rotary axis allows additional faces or features around a part to be machined with fewer setups, helping improve positional consistency.

  • Features on multiple sides
  • Rotational or indexed features
  • Holes around cylindrical surfaces
  • Components otherwise requiring repeated repositioning
  • Better positional consistency between different faces

4-axis machining adds a rotary axis, allowing features on multiple sides or around a part to be machined with fewer setups.

INSPECTION FOCUS

01

Hole Position & Diameter

Hole diameter, position and relationship between multiple holes.

02

Flatness & Perpendicularity

Flatness, perpendicularity and datum relationships.

03

Thread Verification

Thread gauges, mating fit and thread depth where required.

04

Pocket Depth & Feature Location

Pocket depth, steps, slots and critical feature positioning.

05

Thin-Wall & Deformation Control

Inspection of thin-wall, long or stress-sensitive parts where machining deformation may occur.

06

Post-Finishing Dimensions

Critical dimensions and mating features verified after anodizing, plating, painting or coating where required.

Inspection is based on how the part will function, fit and assemble — not only on isolated dimensions.
