Fanuc Control Generation
Way Covers for Series 16i / 18i / 21i Era Machines
Way covers on Fanuc 16i / 18i / 21i era machines split between OEM-available and custom-fab. Many of the machines are still in production and the original integrators (Doosan, Haas, others) still have some OEM cover supply for the most common configurations. Less common configurations and older 16i builds are typically custom-fab.
Machines this control shipped on
Series 16i / 18i / 21i shipped on a wide cross-section of late-1990s through 2000s machines. Many Doosan Puma builds from this era ran 16i/18i/21i; some older Haas imports as well.
Common failures and fixes
- Telescoping steel is the default cover style on 16i/18i/21i era machines.
- OEM availability varies by the original integrator — Doosan and Haas have different parts situations.
- Common configurations (popular VF/ST/Puma sizes) tend to have better OEM supply.
- Less-common configurations may require custom-fab.
Parts availability
16i/18i/21i era way cover parts depend on the original integrator. Doosan and Haas have separate parts channels; both still have some current supply on common configurations.
Battery, memory, and parameter recovery
Custom fabrication is the right path when OEM is no longer available or when timing makes custom better. We can build to existing covers, OEM drawings, or measurements off the machine. Lead time is 2 to 4 weeks.
