As I stated at the beginning I would like to introduce you to one of
our customers, Mr. Tom Frick. We have recently added HEAT to his
machine. I would like him to tell some of his experiences.
TOM FRICK:
My name is Tom Frick, I'm the owner of Intricate EDM in Columbia,
Pennsylvania. I purchased a Makino SP-43 in April and I had the HEAT
technology installed on the machine in July. I got this HEAT technology
and naturally like anybody else you don't believe it until you use it.
I got this certain job that you'll see the pictures of. It's a cast
starlite part, which I believe starlite is stainless steel. Very poor
flushing conditions as you can see. It's typical job shop environment.
You grab a piece of steel just to make a fixture that fixture just
happens to be made of cold raw steel just lying right on the table half
inch thick. You can see in the picture here that all I did was cut a
square out of it but what you don't see is how I started. I started
with a through hole with a counter boar top and bottom which is very
poor flushing conditions plus my half inch thick fixture and I can't
get the head right down on top of the part because the clamp is in the
way. You naturally in a job shop environment you want to try and do as
many as possible. As you can see we can get nine on there. The power
that's on it was a plus or minus a thousandths.
With this
HEAT technology we were able to achieve six tenths straightness on it
and six tenth part tolerance. The technology here is using, it's using
straight brass wire no special coated wires in this case with standard
technology and we were cutting, our cutting speed was roughly seventy,
seventy five thousandths per minutes. With the HEAT I'm holding the
machine back at a hundred and forty-thousandths per minute, which is a
hundred percent increase. You know a cast part, anybody does cast parts
you know that you could have voids in the casting. The casting moves
because it's, there is stress in the casting and all the EDM process is
doing is relieving the stress. We are not really seeing any deviation
or anything in the, by using the HEAT technology we are not getting, we
are not experiencing breakage of wire which you normally would. Part
moving yes the part moves some but we are not pinching the wire having
problems in that respect. You know the HEAT technology with a job shop
environment you never know what's going to be coming in the door next,
as Nick had previously stated and in this case as you can see it's just
a thrown together fixture, it works typical job shop and you know you
don't know. Parts there is no way to hold this part other than that,
it's not round and it's not square. You can't hold it in any vise. You
have to fixture it somehow and this is how we came up with a fixture.
NICK CASBAR: Is this typical of, what kind of percentage of work that you do now is like this Tom, is poor flushing?
TOM FRICK:
Poor flushing, probably about forty/fifty percent. Again you don't know
what's going to come in the door you know and naturally you're not
going to turn it away.
NICK CASBAR: Yeah you
know it's interesting the claims of some of the manufacturers and you
know with what kind of diameters they use with their high cutting
speed. In your experience have you ever purchased a machine as a result
of you know the claims of you using fourteen thousandths wire, is that
real world thirteen thousandths wire? Would you buy a machine or
purchase one for your facility with that kind of criteria?
TOM FRICK:
Well try and get fourteen thousandth wire to begin with. You know ten
thousandths is the standard, twelve thousandths is the standard for the
industry for everybody's machine. Even these manufacturer's that have
to use the thirteen or fourteen thousandths wire to obtain the speeds
that I'm seeing with this HEAT technology but I'm doing it with ten
thousandths wire. Now I'm getting how many feet or yards are on a ten
thousandth spool versus a fourteen thousandths or a twelve thousandths
or a thirteen thousandths spool and you know I'm probably getting
double the amount of wire on a ten thousandths than I am on a fourteen
thousandths.
NICK CASBAR: Couldn't have said
it better myself. That's why I brought it up where what Makino is
trying to do is to develop a real world technology and you know of
course some of the claims that we made to you in the beginning you know
a couple of comments from you is, I got to see it to believe it and you
know one of the greatest parts of my job is to drive down the road and
get a call from Tom Frick and just to thank us to put this technology
on your machine. I remember the day when you did that.
TOM FRICK: It hurt me.
NICK
CASBAR: It did hurt you didn't it? But know it was it is something to
get those kind of results under a real world condition instead of
buying a machine based upon a certain speed that you thought it was
going to go and all of a sudden you can't get the wire because it's
fourteen thousandths or what you were told is really not real world. So
you know the guys at Makino have really come up with something here and
I'm glad you are the recipient because you're a good looking guy. No
I'm kidding.
TOM FRICK: Thank you.
NICK CASBAR: Thank you Tom so much for your effort here.
TOM FRICK:
I just wanted to let you know that I am not being paid by Makino for
this. I believe in the technology that I am using. I didn't believe it
at first until I used it and hopefully other people out there will have
the same experience, pleasant experience that I'm having with it.
NICK CASBAR:
I would like to thank everybody for attending our HEAT seminar and if
you would like to contact me directly you can, you can call you know
the numbers provided and I'll be glad to answer any of your questions.
Thank you very much.
