Shibaura Machine UVM-700E(5AD)

The Shibaura Machine UVM-700E(5AD) is a high-precision 5-axis machining center built around an aerostatic-bearing spindle and linear-motor axes. Three figures define it: a spindle range of 6,000-60,000 rpm, a programming resolution of 0.010 µm on X, Y and Z with 0.0005 µm feedback, and a 500 mm (19.7 in) diameter table rated for 200 kg (441 lb). It is a machine for surface finish and form accuracy on small parts, not for heavy stock removal.

Travel is 810 mm (31.9 in) in X, 800 mm (31.5 in) in Y and 350 mm (13.8 in) in Z, and the A axis tilts ±90 deg. X and Y both reach well beyond the table diameter, so a tilted part can still be covered across its full width. Z is the short axis. Part height, fixture height and tool length all have to fit inside 350 mm, which points to shallow work such as inserts, electrodes and optical forms, where the cutter is small and the depth modest.

The spindle range starts at 6,000 rpm. There is no low-speed band, so large-diameter cutters, tapping and any operation that depends on low surface speed are outside what this spindle does. At 60,000 rpm the natural tooling is small ball and end mills, which need that speed to cut properly at all. Shibaura Machine's table gives no spindle power, torque, tool interface or magazine capacity, and those should be confirmed before a process is planned around the machine.

Feedrates are moderate: up to 15 m/min (591 ipm) on X and Y and 10 m/min (394 ipm) on Z, stated as maximum feedrates. With linear motors and a 0.010 µm programming resolution the emphasis is on smooth, exact motion. The control is the FANUC Series 30i-MODEL B. Overall dimensions are 2,800 x 2,700 x 2,750 mm (110.2 x 106.3 x 108.3 in) and the machine weighs 9,700 kg (21,385 lb), a great deal of mass for a 200 kg payload, so the floor it stands on deserves as much attention as the machine.
