The ML-600LT is a long-bed linear way CNC turning center with sub-spindle, built for a specific problem: long parts that need machining on both ends. Without a sub-spindle, that means re-clamping a long, heavy workpiece, with more alignment risk than almost any other part type. On the ML-600LT, the 6-inch sub-spindle takes the part from the main spindle and finishes the back end in the same cycle, up to about 1,210 mm of machining length on the 10-inch main chuck.
The linear way construction keeps the long traverses fast. For high length-to-diameter parts, the steady rest is configured for your workpiece before the machine ships, and the main-to-sub transfer is proven on your part at our factory. C-axis and live tooling are optional.
Within the linear way sub-spindle family, the ML-600T covers parts to about 475 mm, the ML-600MT to about 710 mm, and the ML-600LT reaches about 1,210 mm for genuinely long work.
Long parts that also carry off-center features? The ML-600LTY adds Y-axis with live tooling standard. Long-part turning without back-end machining? The ML-600L keeps the full 1,280 mm envelope. See also: Long-Bed CNC Turning Centers.
A: Up to 1,210 mm with the standard 10-inch main chuck (1,190 mm with the optional 12-inch). The sub-spindle carries a 6-inch chuck with a Φ56 mm bore, running up to 6,000 rpm.
A: When the long part needs machining on both ends. The LT trades about 70 mm of machining length for the sub-spindle, finishing back faces, threads, and bores in the same cycle instead of a risky second setup.
A: Yes. For high length-to-diameter workpieces, the steady rest arrangement is configured and tested for your part before the machine ships.
