The BML-800S opens the 800 series: a Φ800 mm swing box way turning center with a 15-inch chuck, Φ620 mm maximum machining diameter, and 1,000 mm of machining length. The spindle runs through a two-step gearbox to 2,000 rpm, trading top speed for the low-end torque that large-diameter, heavy-depth cutting demands. Spindle bore starts at Φ134 mm with options to Φ182 mm, which is what puts oilfield tubulars and thick-walled pipe work inside this machine’s envelope.
Every 800 series bed is a long-part platform from the shortest option up, and the box way is hand-scraped along its full length for the damping that keeps heavy cuts quiet.
Machining length is the ladder: the BML-800S covers 1,000 mm, the BML-800M reaches 2,000 mm, and the BML-800L extends to 3,000 mm. Parts carrying flats, cross-holes, or keyways? The BML-800SY adds Y-axis with live tooling standard. Smaller work in the 10-inch class? The BML-600 family covers it (see: Long-Bed CNC Turning Centers).
A: 1,000 mm, with a 15-inch standard chuck (12-inch, 15-inch oversize, and 18-inch options), Φ800 mm swing, and Φ620 mm maximum machining diameter.
A: When part length exceeds 1,000 mm. The 800M reaches 2,000 mm and the 800L extends to 3,000 mm, with the same chuck class, gearbox spindle, and box way construction.
A: Yes. The standard spindle bore is Φ134 mm with options to Φ160 and Φ182 mm, sized for oilfield tubulars, thick-walled pipe, and other large through-bore work.
