The ML-800LY is the longest-reach Y-axis configuration on the linear way side: 2,925 mm of machining length with a 15-inch chuck, ±80 mm of Y-axis travel, and C-axis with live tooling as standard. It exists for the hardest version of the long-part problem: shafts and rolls approaching three meters that also carry keyways, flats, and cross-holes along their length, where re-clamping on a milling machine is the riskiest operation in the plan. The 60-degree bed holds rigidity across the travel, and the steady rest is configured and tested for your part before shipment.
The ML-800Y and ML-800MY carry the same capability at 925 and 1,925 mm. Turning only? The ML-800L keeps the full 3,000 mm envelope. Heavy interrupted cuts? The BML-800LY is the box way version. See also: Long-Bed CNC Turning Centers and Y-Axis CNC Turning Centers.
A: 2,925 mm, with a 15-inch standard chuck, ±80 mm of Y-axis travel, and C-axis with live tooling as standard.
A: The LY adds Y-axis machining for features along the part, trading 75 mm of machining length (2,925 versus 3,000 mm). The 800L is the turning-only version.
A: With tailstock engagement and steady rest support matched to the length-to-diameter ratio. The steady rest arrangement is configured and tested for your part before shipment.
