Start/Stop spindle noise

permalink

Hi,

I'm pretty new with cnc machining. I am using a Haas Office Mill OM-2A for prototyping.

I machined steel with a 3/8" end mill a bit too fast and since then, there is a noise (a ticks like something was loose) when the acceleration is to big (when I start the rotation or stop it)

I tried to press power off while the tool was spinning to see if it was mechanical or braking, and the tool decelerated slowly without any anormal sound.

What could cause this sound ?

Thank you for your help
