Does it not have a spindle lock? I have never seen a manual mill that didn't, some work better then others of course.I'm trying to figure out how to lock the spindle from turning
That mill and others use a second wrench to hold the spindle when tightening/loosening the drawbar.Does it not have a spindle lock? I have never seen a manual mill that didn't, some work better then others of course.
If it is a drawbar collet spindle machine there must be some provision for locking the spindle in order to tighten or loosen the drawbar without rotating the spindle.
A simple difference in nomenclature I suspect, if a device stops a spindle from freely rotating I call it a lock, a brake is also an accurate description.The machines I have worked with have a spindle "Brake", but not a spindle "Lock".
You would probably be better off not trying to mill hardened steel. Very quickly you can ruin expensive tooling. Abrasive grinder will do the job.Yeah, it's hardened steel definitely. I was running my file on it and it was gliding smooth. I need to invest in carbide end mills or cobalt.
Which ones are better for hardened materials? Carbide or cobalt? And what coating?
