Hawk M-Class CNC Turning Centers Go Digital and Live

The digital revolution has been brought to the Arrow line of vertical machining centers for round parts processing. According to Cincinnati Machine, A UNOVA Company (Cincinnati, OH), it's all part of a standard package provided for the company's new line of digital Hawk M-Class CNC turning centers. Available in 6, 8, and 10 in. models, the M-Class Hawks combine the benefits of digital vector servo-axis drives, digital Heidenhain X-axis linear scales and live rotary tooling capability.

In addition, machine design also includes the latest maintenance-free linear guideway technology to provide sliding friction 1/50 that of conventional guideways, significantly reducing stick-slip to ensure smoother processing at ±0.000040 in. micron-level repeatability.

The servo-driven 12-station VDI turret provides bi-directional indexing. Turret indexing can occur on the fly without disengaging the drive. This results in rapid 0.3 of a second chip-to-chip times. All turret stations have live tooling capability, allowing users to mix and match static or powered tools for milling, drilling, tapping, and boring operations.

This multitasking capability improves surface-to-surface part accuracies while virtually eliminating secondary machining operations, optimizing part processing flexibility with one setup/one machine throughput efficiencies. It also saves on the cost of redundant tooling and even redundant machines.

Hawk turning centers are standard with the GE Fanuc 21i-TA CNC control. Hawk options include a parts catcher, automatic tool setter, high-pressure coolant, bar feed interface, bar puller, collet chuck, plug-in footswitch, and chip conveyor.
