Re: Torque for ER20 and ER32 collets
hy, try bearing nuts ... they will protect your collets, and also they are more responsive when tightening, due to less friction : this means that what you feel has less ' noise ', thus represents better how much grip will be there; also, with such nuts, the tightening curve is smoother
if possible, avoid torque wrench for these collet sizes, and try to develop your skills
just like gentlegiant said, if you push an endmill too hard, it will pop-out anyway ... don't try to avoid that by overtightening, but lower your specs, or, if you wish to push your specs, then use weldon holders ( or whatever else, depending on buget ) / kindly
ps : keep the threads clean, air blow should do it ... no need for extra caution with er25 er32 ( since they are like bricks if used with minimal atention ), but only with little ( <=er20 ) or precision collets ( like those ones for gang spindles )
