Okuma Series Repair

Okuma Heavy Lathes (LAW / LFS) Spindle Repair & Grinding

Okuma LAW and LFS heavy-lathe spindles — LAW 1000 through 3000 heavy lathes and LFS-590 flat-bed turning — handle very large workpieces under very heavy cuts. The spindles are scaled to match: larger bore, larger bearings, heavier-duty drives. Wear patterns track the loads more than the cycle count — these machines see fewer cycles but each one matters more.

Models in this series we service

  • LAW 1000
  • LAW 2000
  • LAW 3000
  • LFS-590

Common failure patterns

  • Large-bore spindle wear on sustained heavy roughing cuts.
  • Way wear from extended heavy-cut production affecting spindle-side alignment.
  • Hydraulic chuck pressure loss on large workpieces affecting bearing preload.
  • Drive amplifier faults from heavy-cut loads.

Controls used on this series

LAW and LFS run on OSP-P200 on older builds and OSP-P300 on current.

Lead time

Lead time depends on the model, the failure mode, and parts availability. Diagnostic is fast; full rebuilds run 3 to 5 weeks on most jobs. We scope each job individually rather than quoting a generic window.
