The BML-800M is the mid step of the 800 series: 2,000 mm of machining length in the Φ800 mm swing class, with a 15-inch chuck and a two-step gearbox spindle running to 2,000 rpm. This is the envelope where drive shafts, rolls, and long hydraulic bodies live, parts too long for the 600 family and too heavy for linear ways to damp comfortably.
The box way is hand-scraped along the full two-meter-plus travel, and spindle bores from Φ134 to Φ182 mm keep long tubular work on the table. For high length-to-diameter parts, the steady rest is configured for your workpiece before the machine ships.
The BML-800S covers parts to 1,000 mm and the BML-800L extends to 3,000 mm, with the same class and construction. Features along the length? The BML-800MY adds Y-axis with live tooling standard. See also: Long-Bed CNC Turning Centers.
A: 2,000 mm, with a 15-inch standard chuck, Φ800 mm swing, and Φ620 mm maximum machining diameter.
A: When parts run between roughly 1,000 and 2,000 mm. Below that, the 800S saves floor space; beyond it, the 800L carries the full 3,000 mm envelope.
A: Yes. For high length-to-diameter workpieces, the steady rest arrangement is configured and tested for your part before the machine ships.
