Custom 3 Axis CNC Machining for Prismatic Parts

3 axis CNC machining moves the cutting tool along X, Y and Z to cut flat faces, pockets, slots and perpendicular holes, with no rotation. It is DEK’s default route within our CNC machining services for prismatic parts.

Every quote is reviewed by engineers who read your drawing, not an automated calculator, and there is no MOQ: one prototype and a production run follow the same process. Parts needing turned features too are covered by our milling services and CNC turning services under one quote.

Why Manufacturers Choose DEK

Two decades of precision machining, one shop from prototype to production, and engineers on every quote.

  • 20+ Years of Machining

    More than 20 years in precision machining, with 1.2M+ parts machined annually across prototypes and production orders.

  • 98.6%+ On-Time Delivery

    2300+ global OEM clients rely on our schedules, with on-time delivery above 98.6% and shipping in as fast as 1 day.

  • No MOQ, Same Review

    Engineer-reviewed quotes with no MOQ: a single prototype or a production run gets exactly the same review process.

  • Prototype to Production

    Prototype and production run in one shop, so you never re-quote the same part with a second vendor when volumes grow.

Engineering Review Before Quoting

Engineers check your CAD file against tolerance and geometry before quoting, and flag features that need a second setup or a tighter grade, so cost drivers are visible before you order.

3 Axis CNC Machining Capabilities

Tolerance grades, equipment, lead times and quality controls for every part we run on 3-axis vertical machining centers.

  • 3 Axis CNC Machining Tolerance

    ±0.005 mm is our standard grade on aluminum, steel and most alloy geometry, verified by in-house CMM inspection.

    • ±0.003 mm only on sub-10 mm or micro features called out
    • Tighter grade suits fit-critical dimensions and coaxiality
    • Titanium and Inconel default to the ±0.005 mm standard
    • Not applied blanket-wide: it adds machine time

3-Axis vs. 5-Axis Machining and CNC Turning

Default to 3-axis for flat faces, perpendicular holes and pockets; escalate for undercuts or compound angles. See how 5-axis machining works.

Industries We Machine For

3-axis parts serve aerospace non-flight-critical hardware, medical device housings, robotics, semiconductor equipment and industrial automation.

3 Axis CNC Machining Applications

3-axis is the right call for any part built from flat faces, perpendicular holes and simple pockets or contours.

  • Brackets & Mounting Plates

    Flat faces and perpendicular holes in aluminum or brass. See our machined brackets.

  • Enclosures & Housings

    Pocketed housings and enclosures, common in medical device and electronics work.

  • Manifolds with Straight Bores

    Manifolds whose bores run straight and perpendicular, reachable without rotary axes.

  • Jigs & Fixtures

    Shop and production jigs and fixtures built from flat, square reference faces.

  • Drone Frames & Mounts

    Lightweight frames and mounts machined to the same tolerances. See drone CNC machining.

  • Ultra-High Purity Fittings

    Ultra-high purity fittings for semiconductor and gas systems start from prismatic 3-axis cuts.

Material Challenges We Handle

  • Work-Hardening Stainless

    Stainless steel work-hardens under the tool, so we use sharper cutters and lower feed rates to hold finish.

  • Heat in Hard Alloys

    Inconel, titanium and Invar generate heat and dull tools fast: cycles run longer, tolerance stays the same.

  • Plastic Clamping Deflection

    ABS, nylon and polycarbonate machine easily but deflect under clamping pressure, so fixturing is kept deliberately light.

  • Melting at the Cut Edge

    PEEK, PEI and PTFE need lower feed rates and sharp tooling to avoid melting or smearing at the edge.

Certified Quality at Every Stage

Every 3-axis part runs under one QMS with in-house CMM inspection, whatever the order size.

Our 3-Axis Machining Process

  • 1

    Design Review

    Engineers check your CAD file against tolerance and geometry before quoting.

  • 2

    Programming

    CAM tool paths are set for the material and finish you specify.

  • 3

    Machining

    The part is cut along X, Y, Z, repositioned only if a second face needs work.

  • 4

    Inspection & Finishing

    CMM-verified dimensions, then anodizing, plating or powder coating as needed.

Frequently Asked Questions

Quick answers on what 3-axis machining covers and when to move up to 5-axis.

What can a 3-axis CNC machine do?
It cuts flat faces, pockets, slots, holes and simple contours by moving the tool along X, Y and Z. That covers brackets, plates, housings and fixtures: any part that does not need undercuts or compound-angle access in a single setup.
What is the difference between 3-axis and 5-axis CNC?
5-axis adds two rotational axes, so the tool reaches undercuts and compound-angle features in one setup instead of multiple repositions, at the cost of more complex programming. 3-axis stays the fastest and cheapest option for prismatic parts.
What tolerance does 3-axis CNC machining hold?
±0.005 mm is the standard grade on aluminum, steel and most alloy geometry, verified by in-house CMM. ±0.003 mm is available on sub-10 mm or micro features called out on the drawing; titanium and Inconel default to ±0.005 mm.
