Need Help!- Stupid simple but??

[CDTINC]

We have a an Old mazak QT10 that we acquired with a t2 controller. We are learning the mazak language and that seems to be doing well. We are working on a program to drill a hole but the drill keeps coming out offset apparently by half the width of the drill bit. I can't seem to find where to change this.

I can change the direction it is offset by touching off on the top or the bottom. I know this is porblably simple but can anyone help me out here. I can't seem to find it in the book.

Do you have a parameter book?

Hello scott,

What g code are you using to drill the hole?

No I don't have a parameter book. Do you think that it is a parameter problem?

We are using the mazatrol language.

Yes, the retract amount defaults are set in the parameters, atleast on my M32. You should be able to find a list of your parameters online. I'm not familiar with mazatrol so I can't speculate as to what the problem may be with your program.

Just sounds like a parameter too me.

Thanks for the help. We are just compensating for it in the tool offset table. I guess I just assumed that if I set the tool up as a drill then the offset for the x axis would have been preset to the correct zero. Apparently not.

Scott-

If all your trying to do is set the tool to X0, go to the tool data page 1, select the tool# X position then use the increment button and then add/subtract the distance offset to bring it back to X0.

Also, on tool data 2, insure that the correct drill diameter is listed.

Hope this helps.

Sounds like the machine things youre drill are an internal turning tool, that exact thing happens when this is wrong in the tooldata 2

Also have you set the standard value for the drill holder?

On my Mazak SQT18MS Mark IIthe standard ofset for drill/internal turning holder are -320mm

You should check both theese things, hope this helps.

On tool data 2 its the first thing you choose in the toll line for the toll you are setting the data for.

Ah, just too mention it, if you only change the diameter of the drill to the current diameter of the drill, but dont change the tool type to a drill, the machine thinks the drill size are the actual nose radius of the turning tool, therefore the tool gets out of center by about half its size

do not set the x axis with the tool eye on drills only.
it does not matter what size drill you use the x distance is always the same
for example my mazak sqt 8 is 170mm this is the fixed distane from home to the centerline of the chuck.
hope this helps

I ran a QT-10 for years. If the tool is not coming down to X center it is because of one fo two things:

1)The tool is not defined correctly
2)The X-offset is not correct (-10.5")

Any center cutting tool should be -10.5 if your home position is correct. If it is not, let me know and I will give you the parameter to fix it. To check to see if it is correct, put an indicator in the chuck and indicate one of the #2 holders on center. The machine postion should read -10.5 or very close to it. If it does not, let me know. Also, what is the X-value when the machine is drilling without your offset in?
