Multi-Axis CNC Machining in One Setup

Multi-axis CNC machining adds one or two rotary axes to X, Y and Z, so features on several faces share one datum instead of stacking error across re-clampings. See 4-axis CNC machining and 5-axis CNC machining.

Typical parts are impellers, manifolds with angled ports, medical implants, turbine blades and turned shafts with milled flats and cross holes. Multi-axis work runs alongside 3-axis milling, turning, EDM and grinding under our CNC machining services; the 5-axis machining guide explains the kinematics.

Why DEK for Multi-Axis Machining

One shop, one quality record: from a 5-axis roughed housing to a ground bore, every part is reviewed by an engineer before quoting.

  • Every Process In-House

    3-, 4-, 5-axis milling and mill-turn alongside Swiss turning, EDM and grinding, so a multi-process part stays under one quality record.

  • CMM-Verified Tolerance

    ±0.005 mm standard tolerance, verified on CMM with first article inspection (FAI) on the first batch before production continues.

  • Certified Since 2002

    ISO 9001:2015, ISO 13485 and AS9100D certified by TÜV, with 20+ years of precision machining experience since 2002.

  • Fast, No MOQ

    No minimum order: prototypes in 3–5 days, small batches in 4–7 days, and worldwide delivery in 3–7 days.

Engineering Review on Every Drawing

An engineer reviews every drawing manually, so the quote reflects the real setup count. Parts are routed to the lowest-cost process that holds the drawing, even if that is 3-axis.

Multi Axis Machining Capabilities

Four axis configurations, one goal: the fewest setups that hold your drawing, from indexed shafts to continuous 5-axis contours.

  • 4-Axis Indexing (3+1)

    A rotary table indexes the part around one axis between cuts, reaching four sides in one clamping.

  • Simultaneous 5-Axis Machining

    3+2 tilts the part to a fixed compound angle; simultaneous 5-axis machining moves all five axes during the cut.

    • 3+2: angled holes, faces and underside features

  • Mill-Turn Machining in One Chucking

    Mill turn machining turns diameters and threads, then live tools mill, drill and tap on a C-axis while the part stays in the chuck.

    • Fittings with hex flats, valve stems with slots
    • Sub-spindle finishes the back face

    One-setup machining is what lets features on different faces hold tight tolerance to each other.

Multi Axis Machining vs. 3-Axis and Turning

Choose multi-axis once a part needs four or more 3-axis setups or compound angles; simple parts stay cheaper on 3-axis or standard turning.

When Multi Axis Machining Fits

Multi-axis earns its higher hourly rate on geometry that would need angle plates, sine fixtures or four or more 3-axis setups.

  • Compound-Angle Features

    Angled manifold ports, tilted bosses, holes at 37° to two datums: one 3+2 tool path instead of angle plates or sine fixtures.

  • Contoured Surfaces

    Impellers, propellers, turbine blades, mold cores and orthopedic implants cut with simultaneous 5-axis motion and short tools.

  • Parts Needing 4+ Setups

    Each 3-axis setup costs 15–45 minutes and adds 0.01–0.02 mm error; past four, 5-axis is usually cheaper and more accurate.

  • Coaxial Bores, One Setup

    Bearing bores on opposite faces coaxial within 0.01 mm, or a bolt pattern tied to a back-face feature, cut without moving the part.

  • Complex Multi-Face Parts

    Housings and brackets with features on five faces: see our complex parts CNC machining.

Design Tips for Multi-Axis Parts

  • Give the Tool Room

    Leave clearance around deep features so the head can tilt; a pocket ringed by tall walls on all sides forces long tools.

  • Model Compound Angles

    Angled holes and faces need their angles and a clear datum on the drawing; "as per model" works for geometry but not for tolerance.

  • Keep Tolerances One-Setup

    If two features must be within 0.01 mm of each other, make both reachable in one clamping; our DFM review flags cases where it is not.

  • Leave a Clamping Surface

    Provide a face or boss to hold; a sacrificial tab removed afterwards is fine and often cheaper than a custom fixture.

Multi-Axis Machining FAQ

Straight answers on 3+2 versus 5-axis, cost, mill-turn and tolerances.

What is the difference between 3+2 and simultaneous 5-axis machining?
In 3+2, the two rotary axes position the part at a fixed angle and the cut is made in three axes, suiting angled holes, faces and multi-side features. In simultaneous 5-axis machining, all five axes move during the cut, needed for continuous curved surfaces such as impeller blades and implant contours.
Does multi axis machining cost more than 3-axis?
Per hour, yes; per part, often no. Once a part needs three or more 3-axis setups, finishing it in one clamping on a 5-axis or mill-turn machine usually costs less and holds tighter position. Simple prismatic parts stay cheaper on 3-axis, and we quote whichever is lower.
What is mill-turn machining used for?
Mill-turn machining makes turned parts that also have milled or drilled features, such as shafts with keyways, fittings with hex flats or housings with off-center hole patterns, without a second machine. Concentricity between turned and milled features holds within 0.01 mm on the same datum.
What tolerance can multi-axis CNC machining hold?
DEK holds ±0.005 mm on metal parts and ±0.005 mm positional tolerance between features machined in one setup. Simultaneous 5-axis contoured surfaces hold ±0.01 mm profile. Every first article is inspected on a CMM before the batch continues.
