4-Axis Production: Getting More From One Setup
How a 4th-axis rotary adds output on VMCs and HMCs: parts that suit it, programming approaches and the accuracy checks that keep it honest.
A fourth axis turns the machine around your part instead of your part around the machine. Families with features on several faces, from pump housings to camshafts, go from three or four setups to one. Every eliminated setup removes a re-clamping error and a queue slot.
Indexing or Simultaneous
- Indexing: rotate, lock, mill. Fast and accurate for face features.
- Simultaneous 4-axis: continuous rotation for cams, helical ports and spiral grooves.
- Most volume work needs only indexing plus good programming.
Accuracy lives in the details. Check rotary runout and backlash with a test indicator, calibrate centre height once and record it, and design fixtures that locate from machined datums rather than the rotary surface itself. A tailstock transforms rigidity on long parts.
Our machines offer fourth-axis options with matching controls and probing, configured around your part drawings rather than a generic package.
