Frequently Asked Questions

How fast does the automatic compensation system work?+
Hunter's direct compensation system automatically compensates in 12 seconds or less on average, eliminating guesswork and reducing setup time compared to other methods that may take up to two minutes.
What is Anti-Chatter Technology and how does it help?+
Anti-Chatter Technology is a patented system that varies the spindle speed to prevent vibration buildup during machining. This results in a smoother surface finish and allows the lathe to cut approximately twice as fast as traditional fixed-speed lathes.
How does the Digi-Cal system prevent cutting errors?+
The Digi-Cal system instantly measures rotor dimensions and depth of cut from the end of the cutter shaft. It displays warnings when attempting to cut below manufacturer specifications, helping technicians avoid discarding rotors or cutting them too thin.
What vehicles can this lathe service with the passenger adaptors?+
The included passenger adaptors service 3-, 4-, and 5-lug vehicles with bolt patterns ranging from 112-210mm, covering nearly all passenger cars and light-duty trucks. When paired with the extended twin cutter, coverage extends to almost all vehicles up to 3500 series trucks.
