Mitsui Seiki’s new PJ 303X 5-axis machining centre processes small workpieces

Mitsui Seiki’s new PJ 303X 5-axis machining centre processes workpieces up to 230 mm tall, 280 mm dia. and weighing 20 kg.

The machine’s X-, Y-, and Z-axis travels are 300, 325, and 200 mm, respectively. A-axis rotation is +40 to -100 degrees, and the C axis rotates a full 360 degrees. 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.

A 50,000-RPM HSK-E25 taper spindle offers high-speed machining capability. An ATC can store up to 24 tools as large as 40 mm dia. and 120 mm long.

Operator-friendly features include a 15-in. colour 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 setup.
