4.3" Doosan DBC-110II CNC Horizontal Boring Mill

The DBC-110II is built for handling large parts in a single setup. This heavy-duty horizontal boring mill features a 4.3" (109mm) BIG-PLUS CAT 50 spindle running up to 4,000 RPM at 35 HP, giving you the rigidity and precision to tackle aggressive boring and milling work without breaking a sweat.

Why the "II" matters:
If you're comparing this to an older DBC-110 (non-II), the upgrades here are real, not cosmetic. The FANUC 31i-A control replaces the 18i/21i found on earlier units, and you get AICC II with 200-block look-ahead, 200 tool offsets, and 48 pairs of work coordinates — a big deal if you're running long, complex programs across multiple parts. The spindle interface also got an upgrade: BIG-PLUS CAT 50 instead of standard CAT 50, which means dual-contact face-and-taper engagement for stiffer cuts and longer tool life.
