Summary

The Haas HRT310SS-BM is a high-speed rotary table designed for horizontal mounting to provide rapid C-axis positioning on compatible CNC mills. Its cycloidal drive system delivers fast indexing at up to 240° per second, intended for applications requiring precise, high-throughput 4th-axis operations. The unit integrates directly with Haas CNC mills equipped with a 4th-axis drive and NGC software.
