Multi-Axis Turn-Mill

Mori Seiki NL2500SY — what we run on it.

Y-axis live turn-mill lathe with sub-spindle. 3.0″ bar capacity, full live tooling on the turret, off-center milling and drilling on the OD, ID, and front faces. Built for production runs of complex bar parts that need lathe + mill in one cycle.

01 · Sweet spot

Bar parts that need cross-features.

The NL2500SY is the right choice when a bar part has axial features (turning, threading, boring) plus cross-features (off-center holes, hex flats, slotting) that traditionally would require a secondary mill operation. Y-axis lets the live tools work off-center; sub-spindle handles back-work for parted-off completion.

  • Hydraulic spool valves with cross-port drilling
  • Aerospace fittings with hex wrench flats and threaded ends
  • Medical instrument shafts with broached drive features
  • Defense pin work with cotter-pin holes and knurled grip features

02 · When NOT to pick this

Wrong-fit jobs.

  • Heavy 5-axis cylindrical work → Doosan SMX 2600ST. The B-axis tool spindle on the SMX outperforms a Y-axis turret for complex 5-axis features.
  • Twin-cut high-volume production → Doosan TT1800SY. Two turrets cutting in parallel halves cycle on simpler geometry.
  • Plain OD/ID turning, no milling → Daewoo Puma 12S or Lynx 200L. Live tooling complexity wasted on simple parts.
  • Bar < 1.0″, high L:D → Tsugami Swiss-type.
