CNC Machine Types

Mill-Turn Post Processor Development

Mill-turn (multitasking) machines complete complex parts in one setup. They are also the most demanding machines to post for, because every model combines spindles, heads and turrets differently.

Mill-turn configurations

ConfigurationExamples
Turning centre + live tools + Y-axisMany 2-axis-plus lathes
B-axis milling head + main/sub spindleIntegrex, NT, Multus, DMG MORI CTX-type machines
B-axis head + lower turretMachines with two channels cutting simultaneously
Twin spindle, twin turretHigh-volume turning cells

Data we collect

  • Spindles, turrets, heads and their axes.
  • Channels and which components each controls.
  • M-codes for spindles, C-axis, live tools, chucks, transfer and waits.
  • B-axis head kinematics, TCP and tilted plane options.
  • Proven programs for each type of operation.

What the post coordinates

  • Turning, C/Y-axis milling and B-axis milling modes.
  • Main and sub-spindle work with mirrored coordinates.
  • Part transfer and cut-off.
  • Channel programs with synchronised wait codes.
  • Safe positions and turret/head interference zones.

Project approach

Phase 1: Turning (main spindle) proven
Phase 2: C-axis / live tool operations proven
Phase 3: B-axis head and tilted operations proven
Phase 4: Sub-spindle and transfer proven
Phase 5: Multi-channel synchronisation proven

Building capability in phases keeps the machine productive and reduces risk.

Simulation is essential

A full machine model with all channels is the safest way to prove mill-turn programs, especially transfers and simultaneous channel motion.
