Designed for automated small- to medium-size part-processing operations, the new AWC excels in machining aluminum and other nonferrous metals for a wide variety of industries, including aerospace, medical and automotive.

The machine comes standard with a multiple drum tool storage system that holds up to 145 tools, while the AWC with 32 positions accommodates workpieces up to 13.779” in diameter, 12.401” high and weighing up to 135 lbs. This combination of ample tool and workpiece storage capacities allows even the busiest shops to achieve continuous unmanned operation and single-setup, DONE IN ONE processing.

As production needs increase, shops can expand the AWC and tool storage capacities to 40 workpieces and 505 tools (in increments of 60 tools), respectively. Despite this large capacity, the machine has a significantly smaller footprint thanks to its stacking 30-tool drum magazines.

In addition to its new features, the VARIAXIS i-300 AWC builds upon the existing success of the VARIAXIS Series. Its standard 12,000-rpm spindle is available in speeds up to 30,000 rpm, and its integral spindle/motor design and temperature-controlled coolant enable vibration-free, high-speed operation. The machine’s trunnion-style rotary table guarantees high rigidity and accuracy in the A and C axes, while its compact spindle cartridge, cam-driven tool changer, ballscrew core cooling and MX Hybrid Roller Guide System all contribute to operator ease of use and machining precision.
