The BML-800L is the longest machine in our lineup: 3,000 mm of machining length in the Φ800 mm swing class, built for drive shafts, rolls, oilfield mandrels, and long cylinder bodies up to three meters. The 15-inch chuck and two-step gearbox spindle carry the grip and torque that parts this size demand, and spindle bores to Φ182 mm keep long tubulars in play.
At this length, guideway consistency is everything: any error accumulates across three meters of travel, which is why the box way is hand-scraped along the entire bed. For slender work, the steady rest is configured and tested for your part before the machine ships.
The BML-800S and BML-800M cover 1,000 and 2,000 mm where the full three meters is not needed. Long parts with off-center features? The BML-800LY adds Y-axis with live tooling standard. For the selection logic on long work, see: Long-Bed CNC Turning Centers.
A: 3,000 mm, with a 15-inch standard chuck, Φ800 mm swing, and Φ620 mm maximum machining diameter.
A: The LY adds Y-axis machining with C-axis and live tooling as standard, at 2,925 mm of machining length, for long parts carrying keyways, flats, or cross-holes. The 800L is the turning-only version with the full 3,000 mm.
A: With tailstock engagement and steady rest support matched to the part's length-to-diameter ratio. The steady rest arrangement is configured and tested for your workpiece before the machine ships.
