Mazak’s HCR-5000S five-axis, single-table horizontal machining center offers a range of high-speed spindle options, from a standard 12,000-rpm spindle up to 30,000 rpm spindle.

Mazak’s HCR-5000S five-axis, single-table horizontal machining center provides the aerospace and semiconductor/high-tech industries with small- to mid-sized aluminum component processing. The machine offers a range of high-speed spindle options, from a standard 12,000-rpm spindle up to 30,000-rpm one, and each feature an spindle/motor and ballscrew core cooling that minimize vibrations for higher accuracy.

A 40-tool auto tool changer, which is expandable to a 160-tool capacity, further boosts productivity with a chip-to-chip tool change time of only 2.8 seconds. The horizontal machining center achieves precision with its single-table design that incorporates a high-rigidity bed, solid base X-axis construction and roller gear cam systems for the A and C axes.

The machine’s tilt/rotary table provides rapid traverse rates of 50 rpm in its C axis and 30 rpm in the A axis. The table positions in 0.0001-degree increments and accommodates parts weighing as much as 500 kg and measuring up to 700 mm in diameter and 644-mm high, depending on the cutting orientation.
