Face Gear Rotary Table

The advantages of rotary tables are undeniable for machining multiple sides of a single part or machining many parts on a multi-sided tombstone. Heavy off-center milling and drilling operations, however, may cause a rotary table to rotate slightly, affecting accuracy. To solve this problem, Haas Automation, Inc., introduced the new HRT320FB face gear rotary table, which provides the extreme rigidity and high brake torque necessary to handle even the heaviest cuts.

At the heart of the HRT320FB is a high-precision face gear coupler (Hirth type) that provides both superior indexing accuracy and extreme rigidity. The 12.6” (320 mm) diameter platter can be positioned in 1 - degree increments, with an accuracy of ±3 arcsec and a repeatability of ±1 arc-sec. Once positioned, the platter offers 3,500 foot-pound of brake torque. This extreme rigidity allows for heavy off-center milling, drilling or tapping operations, even in the hardest materials.
