I’ve been running an HLVH at work without
problem for a few weeks until today.
Up until today facing a piece of round stock
hasn’t been a problem. I noticed today when
I was facing that when I dialed in .020 for
removal when it got to the center of the part
the carriage had apparently backed off approx.
.006 and of course didn’t leave a good finish.
I was using the power feed to face like I
normally do and never had to lock the carriage
to get it to stay in place until today.
I’m not sure what might have changed, I
use collets and the lathe chuck, and I was
using a collet today. The only thing different
I can think of is I was facing 1” dia. stock
which is just a little bigger than what I’ve
been machining.
I’ve been using the same style insert at
a slow rate of rpms and feeds, and the
steel has just been 1018. The insert may
have been worn a little but it wasn’t chipped.
I’m wondering if the carriage is supposed to
lock somehow when you use the power feed
or do you always have to lock it manually?
Any help is appreciated.
