Mitsui Seiki's new PJ 303X 5-axis machining center is designed to provide maximum precision and versatility in processing of workpieces up to 230 mm tall and 280 mm in diameter (9" x 11") and 20 kg (44 lbs.) in weight.
Typical applications cover an extensive range of critical parts such as lens molds, medical products, EDM electrodes and fuel cell components.
The machine's XYZ axes travels are 300 mm, 325 mm and 200 mm (11.8", 12.8", 7.9"). A-axis rotation is +40° to -100° and the C-axis rotates a full 360°. High-speed linear motors move the XYZ axes while the rotary axes employ direct-drive motors. Rapid traverse speed for the XYZ axes is 20 m/min (66 ft/min).
A 50,000 RPM, HSK-E25 taper spindle offers high-speed machining capability. An automatic tool changer engineered to store up to 24 tools as large as 40 mm (1.57") in diameter and 120 mm (4.7") in length provides tooling versatility.
To maximize precision, the sliding machine surfaces of the PJ 303X are hand-scraped.
Advanced spindle thermal displacement technology is standard, including a symmetrical gantry column structure that accommodates thermal deformation fluctuations and a thermal compensation mechanism for the machine spindle/head.
Operator-friendly features include a 380 mm (15") color display with touch panel capability that can be moved to the most convenient position relative to the work envelope. The machine's double-stage rotary door provides wide access for visibility and set-up.
The PJ 303X consumes a compact 1,755 mm (5.75') x 2,370 mm (7.77') x 2,655 (8.7') (WxLxH) of floor space and weighs approximately 4,500 kg (9,900 lbs.).
"The compact PJ 303X machining center provides high precision, speed and versatility for the processing of an important range of part sizes across a wide variety of applications," said Mitsui Seiki USA COO Bill Malanche.
