Citizen Miyano LX-08C

The Citizen Miyano LX-08C is a fixed-headstock CNC chucking lathe built around an 8-inch power chuck, with a maximum machining diameter of 210 mm and a maximum machining length of 320 mm. Its spindle covers 40 - 4,000 rpm on an 11/7.5 kW motor (thirty-minute/continuous rating), and the slides give 175 mm of X travel and 435 mm of Z.

The table lists X and Z travel only. There are no rows for rotary tools, a Y axis or a second spindle, so plan on it as a turning machine: OD turning, facing, boring and centre-line drilling, with any milled features done elsewhere. The low end of the speed range matters on a machine of this diameter class, because a 210 mm part needs only a few hundred rpm to reach normal turning surface speeds, while the 4,000 rpm top end serves the smaller diameters and the bores.

Tooling sits on a ten-station turret. OD tools are held by direct tool mount, clamped straight onto the turret rather than in separate holder blocks, and take 25 mm square shanks. The tool holes are 40 mm in diameter, which sets the largest boring bar shank the turret accepts and, with it, how deep a bore can be reached before the bar overhang becomes a problem.

For long work the LX-08C has two tailstock arrangements in its table. The quill type is rated at 3116 N (318 kgf) of maximum thrust and the slide type at 5,488 N (560 kgf), so the slide type is the one to look for when shafts toward the 320 mm limit are turned with heavier cuts. The MT4 tailstock taper is marked as an option. The machine alone occupies 2,035×1,690 mm of floor and weighs approx. 4,500 kg.
