My first run: collet chuck adapter failed
Posté : 23 juin 2018 21:42
After more than half a year since I've started ordering parts, today I finally started my first mill! Unfortunately, it lasted only 20 seconds You can watch it here:
As you can see, small adapter came off the chuck! I think the problem may be, that it was a little too tight for my bit (bit measured about 3mm, less than 1/8 for sure!) and I haven't put the bit deep enough inside it. By the way, the feedrate was 500mm/min. Is it ok for a plywood or should I make it slower?
And the question is - is there some standard by which katsu collets are made? Is it ER11 or something else? I think I would like to buy a chuck holder/adapter locally and of better quality than the stuff directly from china. But I'm not sure what to search for.
Any comments welcome!
