Summary

The Haas HRT310SS is a high-speed 4th-axis rotary table engineered for rapid positional indexing of workpieces on CNC milling machines. Its cycloidal drive system delivers up to 240°/sec indexing, supporting accelerated machining cycles and integration with compatible Haas CNCs. The unit is designed exclusively for vertical mounting and requires a Haas mill with 4th-axis drive and NGC software version 100.21.000.1130 or later.

Key Capabilities

• High-speed indexing up to 240°/sec via a heavy-duty cycloidal drive system
• Direct plug-and-play integration with Haas mills for 4th-axis operation
• Precision positional control with 0.001° resolution and ±30 arc-sec accuracy
• Six T-slots on 310 mm platter for versatile workholding
• Operates exclusively in the vertical position (platter face perpendicular to ground)
