Hi. Jason with Tormach. Let's talk about how to use your Haimer to set up your
work offsets. The first step to using your Haimer successfully, is to making
sure that it's properly calibrated. We did an entire video on this. If you
haven't done this already, please check out that video.
So the Haimer is kind of a unique edge finder. It allows you to set X,Y, and Z
axis all with the same tool. So it's really a time saver when you're setting up your
machine. So you can see on our dial face here, when we move the stylus over we get
the two indicator needles move with it. When we line both the small red needle
up and the large black needle on zero, it compensates for the diameter of the ball.
So it also makes it quicker since we don't have to remember what size and it
just kind of reduces some error opportunities, but it also works in Z. So
to use this with Z, we need to set the tool length like we do all of our other
tools. In our system, the way we like to teach tool offsets, is the distance from
the spindle nose to the tip of the tool. This tool is a little unique when you're
comparing it to like a solid end mill, there's no compliance in an end mill. With
the Haimer, there is some compliance so we need to preload the Haimer to the zero
location to make sure that we have an accurate length. So to measure the tool
offset you really just want to do the same process you're gonna do to set all
of your tools. So if you're going to use our height gauge, measure your Haimer with the
height gauge. If you're gonna use a piece of paper, or touch the parts off, and your
tools off in your machine, then you want to set your Haimer the same way.
Consistency is truly key when you're looking for accuracy while
machining. So we're gonna go ahead and show you how to do it on the granite
block here. So what we do is we just put the height gauge down right on the top. We
zero this out. And what this is representing in the machines mind is the
spindle nose. So we zero this out on the spindle nose. we raise it up, and we
preload it. As we put tension on this, the easy way to do it's the height gage has
a little lock on it. So we can lock this top portion then we can use the thumb
screw to dial it down to zero. So then we just watch our face here as we dial down
and we just keep going until we make it to zero.
So as you can see, we have four point seven six five five. One thing to note is
if this is under tension, it is a spring tension so if you don't put a little bit
of pressure here it can lift up the indicator but..the height gauge base. So
it's just kind of good practice just to kind of keep a little pressure here
while you're checking your number. So just again it's four point seven six five
five. So once we have our number then we can just enter that into the offset
table and PathPilot. So we jump to our offsets tab, we go down to the tool
number we want to enter that we're gonna use tool fifty we're gonna enter a
description here so just put heimer and i'm gonna enter my length offset at my
four point seven six five five then we should enter the standard stylus on the
timers is right about an inch long they do make an optional long reach stylus
which is a little bit over two inches long this is nice we just need to reach
down into a board a set of zero the ball diameter is larger on the long stylus
since the heimer compensates for that diameter on the small one when we make
that stylus longer we need to make the ball bigger to compensate for the change
in throw needed to put the indicator back on zero so it's great little tool
to have your toolbox if you need it but just as a note it does make the diameter
larger so something to keep in mind so the long stylus installed i had a length
of six point four zero four five I'll go ahead and enter that in is another tool
offset so that if I need to switch to this stylus I don't have to measure the
tool later I'll be able to just swap stylus back and forth on this same timer
and use whichever one's appropriate so I'll enter that length in here in the
offset table as well let's make that tool 51 I'll just call it high your long
and our six point four zero four five so now whichever one I need to you is I can
just activate the appropriate tool length and pretty quickly get my part
set on so you see we're going to use the short one for the part we're setting up
so we're going to activate tool fifty I'll put the heimer in the machine
so in this part we're gonna set this back left corner on the top is their
zero and then we'll also set the center this pocket is the zero to show you guys
how to find center of a bore or find center of a feature real quickly so
we're going to a dog a machine over come over we'll set our expositions we're
just gonna jog down Knight to the side I'm gonna jog the Machine over and with
the jog set on the outer wheel you can move it the farther you move it the
faster it goes so we can get somewhere quickly and then we can slow down so we
don't break the tips off of these so we'll walk it over as we start to see
the indicator engage when we almost get to zero we'll stop and then we'll switch
to our Center wheel and we'll just dial this right over to zero from here we can
really just hit X 0 the heimer is compensate for the diameter and
everything so when you're on zero you're on the edge of the part it makes it real
quick and easy to set your zeros so we'll jog back on Y bring it over and
we'll set our Y position the same way
don't say y zero
one thing to keep in mind and just to always think of all while you're
studying your zeros make sure you have your tool links activated
I still get myself in this every once while you just get in a hurry and you
forget to do it so always just double check to make sure that the appropriate
tool is loaded so we have tool 50 activated on path pilot then we can come
down and Z and we can set it set our zero position so you jog it close walk
it in nice and slow right at zero there so we can say Z zero so you can see it's
a real quick process with this tool it's really it's really kind of a fun nice
tool to use an abra on the shop another nice thing about it and rate feature is
it's really quick to set the center of a features a is a zero as well whether
it's the center of AB or if you're gonna use the outside of this rectangular
block to set it I mean here we'll do the inside of this this pocket so just bring
it down we'll come over and Y will touch the edge of the part will hit zero I'm
gonna jog to the other side of the pocket
walk it up to zero then in our right in our dro on the Sun path by here we're
gonna select our box so we're just going to hit the right arrow to get to the end
of it and we're gonna say divide by two and this is gonna go ahead and do the
math for us putting the zero right on center really makes it quick and easy
the the less you can do math throughout the day the less opportunities you have
the make mistakes so I always anytime the machine can do it for me I am a big
fan align and do the work so we'll just do the same process here and x0 on the
one side of the pocket
find the other side click on RDR o again hit the right arrow and then just say
divide by two and that puts this on center so now if we just drag the
machine up to a safe position we can jump to our MDI line type in g 0 x 0 y 0
and the machine will move this Center you can see we've found our zero
position Center so I hope this helps you guys use your himer effectively if you
