IMTS 2022 visitors can see Mitsui Seiki’s PJ 303X five-axis machining center in action in booth #338700, demonstrating its 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.
A key feature Mitsui Seiki highlights is that the PJ303X is designed to accurately machine smaller parts — including molds — rather than large, critical components. Its X-, Y-, and Z-axis travels are 300 mm, 325 mm and 200 mm (11.8", 12.8", 7.9") respectively. A-axis rotation is +40º to -100º, and the C-axis rotates a full 360º. High-speed linear motors move the X-, Y- and Z-axes, while the rotary axes employ direct-drive motors. Rapid traverse speed for the X-, Y- and Z-axes is 20 m/min (66 ft/min).
A 50,000-rpm, HSK-E25 taper spindle is said to offer 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 100 mm (3.9”) in length provides tooling versatility.
To maximize precision, Mitsui Seiki says the attachment surfaces of the ways as well as other critical areas 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 further enhance precision.
The company also has its PJ812 VMC on display. The “J” represents “Jig,” which is ideal to machine critical medical, optical, electric vehicle, mold and die and aerospace parts.
The International Manufacturing Technology Show runs September 12 - 17, 2022 at McCormick Place in Chicago. Register for IMTS today to start planning your show.
