G'day,
I am pretty new to this, but have just purchased an X2 Mini Milling machine and need some help with regards to the collets.
It has an MT3 spindle, however, I don't fully understand the benefits and subtle differences between the different ranges of collets (ER16, ER20, ER25 etc etc). I assume this is to do with the over-all sizing of the set, but why should I choose any particular size over another?
I don't really expect any of my mills to exceed 10mm diameter, with the smallest being probably 2mm diameter, therefore from various charts I have seen ER16 would do...am I right, or am I really missing something, some other reason another size would be better?
Any help greatly appreciated with this...or even if any one knows of another thread where a good run-down on colelts is given, feel free to point me in the right direction (I have done a few searches but found nothing).
Thanks.
Colin
