The ML-600T is a linear way CNC turning center with sub-spindle, built for parts in the 8-inch chuck class that need machining on both ends: back faces, second threads, bores from the other side. When front-end operations finish, the 6-inch sub-spindle takes the part directly from the main spindle, both spindles synchronized, and the back end is machined in the same cycle. Machining length runs to 475 mm.
The linear way construction keeps traverse and positioning fast, which is exactly what bar-fed and high-mix production needs when every part carries a second operation. C-axis and live tooling are optional, so if your back end needs turning only, you skip the cost of milling capability you will not use. Before shipment, the main-to-sub transfer is proven on your part at our factory.
Within the linear way sub-spindle family, the ML-600T covers parts to about 475 mm on an 8-inch main chuck, the ML-600MT extends to about 710 mm on a 10-inch chuck, and the ML-600LT reaches about 1,210 mm for long parts.
Off-center features on either end? The ML-600TY adds Y-axis with live tooling standard. Heavier cutting on tougher parts? The BML-600T is the hand-scraped box way version (see: Sub-Spindle CNC Turning Centers).
A: Up to 475 mm with the standard 8-inch main chuck (465 mm with the optional 10-inch). The sub-spindle carries a 6-inch chuck with a Φ56 mm bore, running up to 6,000 rpm.
A: When your parts fit within about 475 mm and the 8-inch chuck class. The MT steps up to a 10-inch chuck and about 710 mm; the LT reaches about 1,210 mm for long parts.
A: They are optional, not bundled. If your back end needs turning only, specify the machine without live tooling; if you need back-end milling or cross-drilling, add the option or consider the ML-600TY with Y-axis.
