GD160LP Low-profile Indexer0 pages

160 and 210mm
Low-Profile Rotary Table Indexers
Sleek, fast and accurate. Engineered to support heavy loads and high-force cutting applications while
maintaining accuracy over a long life. Fast clamp and release in milliseconds gives you increased parts-per-hour.
Hardinge rotary tables have collet-ready spindles for increased part gripping options.
