2014 AKIRA SEIKI PERFORMAJR VERTICAL MACHINING CENTERS

Technical Description

The Akira Seiki Performa JR is a 3-axis vertical machining center from Akira Seiki's entry-level JR/SR Performa Junior series, designed as a cost-efficient and compact machining platform for general-purpose milling, drilling, and tapping operations. The Performa JR features a BT-40 spindle taper with a 12 HP peak motor and a maximum spindle speed of 11,000 RPM. The worktable measures 560 by 380 millimeters (22 by 15 inches) with a standard workpiece load capacity of 360 kilograms. Axis travels are 410 mm (16.1 inches) in X, 430 mm (16.9 inches) in Y, and 460 mm (18.1 inches) in Z. Rapid traverse rates are 36 m/min in X and Y and 30 m/min in Z. A 16-tool arm-type ATC is standard, with a chip-to-chip time of 2.2 seconds. The machine is controlled by the Akira Mi:845 system (Fanuc G-code compatible). Overall machine dimensions are approximately 94 by 76 inches (2,400 by 1,935 mm), with a machine weight of approximately 2,986 kilograms (6,585 pounds). The Performa JR series was designed to offer the rigidity and control sophistication of larger Akira Seiki VMCs in a smaller, more affordable package suitable for light-to-medium production requirements. Standard equipment includes flood coolant, automatic lubrication, chip screw conveyor, and full enclosure.
