The BML-800MY combines the 800 series’ mid-length bed with Y-axis machining: 1,925 mm of machining length, a 15-inch chuck, and ±80 mm of Y-axis travel with C-axis and live tooling standard. Long shafts and rolls that carry keyways, flats, and cross-bores along their length are finished here in one chucking, instead of a second setup that means re-clamping a heavy two-meter workpiece.
The 60-degree bed and hand-scraped box way keep off-center cutting rigid at this scale, and the steady rest is configured for your part before shipment when the length-to-diameter ratio calls for it.
The BML-800Y covers parts to 925 mm and the BML-800LY extends to 2,925 mm with the same capability. Turning only? The BML-800M keeps the full 2,000 mm envelope. See also: Long-Bed CNC Turning Centers.
A: 1,925 mm, with a 15-inch standard chuck, ±80 mm of Y-axis travel, and C-axis with live tooling as standard.
A: When the long part carries off-center features. The MY machines keyways, flats, and cross-holes in the same cycle as the turning, trading 75 mm of machining length for the capability.
A: Yes. For high length-to-diameter workpieces, the steady rest arrangement is configured and tested for your part before the machine ships.
