Last operation on your process sheet is knurling.
Okay, knurling is very simple. Here's a picture of the knurling tool. Basically
what you do is you bring these rollers against your part, okay, till they look
like they're about just about in the center, okay. And then you tighten this
big black nut, okay. And I think we are about there.
Now we're hitting our rollers I can feel it here because this won't tighten
anymore. Okay, so when we adjust this to go deeper
we use a wrench here that we've got, okay. So first thing we're going to do is turn
this on. The key issue of knurling is you want to keep half the width of the
rollers on the part in both directions, right and left. If you come off of there
you're going to lose and you're going to cross knurl it. Just like
threading, the same way. So you want to make sure, so like right now we've got
about half the roller on there and I'll come off and leave half on here, okay.
So we're running at a very slow speed, 95. And it takes a significant amount of oil too.
So both rollers should be turning if you can see that?
Okay, so now we're going to feed down. We're
now touching so I'm going to take it one quarter turn.
Okay, then manually we're gonna take it across it.
You want to kind of get a good look at it but you can see where the rollers
at. Okay, do another quarter turn.
Go back the other way make sure you keep the rollers on.
Now we're going to go another quarter turn.
come back over this way.
Again keep your rollers on.
Let's go one more turn.
Back over.
Let's just take a look see what it looks like. Let's take one more cut.
Looks like we're good and that's all there is to it.
This is the conclusion, you can see here the starting blank
