Hello,
I'm new to here and new to CNC. Apologize in advance if I'm asking too basic questions.
I'm working with a wood working CNC from Laguna, swift series. It has a water cooling spindle with ER20 chucking.
This collet chuck nut turns only 2-3 revolution to get snug.
Is this normal only 2-3 threads are working to hold a bit?
I'm asking this because someone said that he cross threaded and ended up to replace entire spindle...
Want to avoid that.
Also so many unused thread on spindle as you see in attached pic.
Is this chucking nut too short? or I'm using too long sleeve etc.?
Best regards,
