Makino PS65

The Makino PS65 is a 40-taper vertical machining center for job-shop production, with 660 mm (26.0 in) of X, 510 mm (20.0 in) of Y and 460 mm (18.1 in) of Z over a 920 x 510 mm (36.2 in x 20.0 in) table. It is the smaller of Makino's two next-generation PS models and carries workpieces up to 600 kg (1,323 lb).

The spindle is a 14,000 rpm CAT40 unit as standard, with HSK-A63 as the option. Makino supports it on large 85-mm (3.35 inch) bearings to keep deflection down, which is what lets a 40-taper machine hold a finish while pushing modern cutters hard. Makino's table gives no power or torque figure, so a shop planning heavy roughing in steel or titanium should ask for the spindle curves.

The axes are quick for the class. X rapids at 48,000 mm/min (1,890 ipm) and Y and Z at 36,000 mm/min (1,417 ipm), with cutting feed up to 30,000 mm/min (1,181 ipm). Heat in the drive train is handled by core-cooled ball screws, with thermally controlled lubrication oil delivered through the ball screw and its support bearing, so positioning holds as the machine runs through a shift.

Thirty tools come as standard, and a 60-tool magazine is the upgrade; each tool may weigh up to 8 kg (17.6 lb). Tools load either at an exterior station or straight into the spindle, so the operator can stage the next job while the current one runs. The PS105 shares the spindle, Y and Z travels and magazine but stretches X to 1,050 mm (41.3 in) on a 1,300 x 510 mm (51.1 in x 20 in) table. Pick the PS65 when parts and fixtures fit within its 920 mm (36.2 in) table length.
