Buy & Sell Used Machine Tools with FANUC Series 21i CNC Control

The FANUC Series 21i (including 21i-M for milling and 21i-T for turning) is the compact, cost-effective CNC solution designed for standard machine tools with up to 4 axes. Delivering the core reliability of the 16i/18i architecture in a space-saving panel-integrated format, it is a mainstay in job shop turning and vertical milling.

Typical Machine Applications

  • 2- and 3-Axis CNC Lathes: Doosan Lynx, Hardinge Cobra, Takisawa, Goodway.
  • 3-Axis Vertical Machining Centers: Robodrill, Quaser, Dah Lih, Leadwell.

Compact Lathes & Mills: Browse our Doosan Lynx lathes and Fanuc Robodrill centers running FANUC 21i controls.

Lifecycle & Retrofit Advisory: Classic Industrial Control

Controllers from this era offer cast-iron electrical reliability. Operators and buyers should observe three essential operational practices:

  • Backup Battery Maintenance: The 3.6V lithium buffer battery retains all critical NCK/PLC parameters and zero offsets. Crucial: Always replace the battery while the control is powered ON to prevent catastrophic parameter loss!
  • Monitor & Memory Retrofits: Aging CRT cathode ray monitors can be upgraded with drop-in, energy-efficient LED/TFT conversion panels. Mechanical hard drives or floppy units can be updated with rugged solid-state CF/SSD adapters or USB DNC emulators.
  • Spare Parts Availability: Reconditioned modular drives, power supplies, and CPU boards remain widely accessible via certified industrial electronics specialists.
