im stumped on dilling these holes

[mikechvz]

those 4 holes are 1.160 dia. the 2 center ones are spaced 4.0 inches from each other edge to edge. ive worked on holes and bores that were partially blocked but they were very small diameters and it wasnt 4 that need to be concentric.

 

Does anyone have a tool/setup suggestion or experience with something similar.

 

the 2 outer holes are also partially blocked by the 45 degree wall nexto it also

 

thanks in advance

What kind of tolerance?  It looks like you could keller them with a lollipop, but if they're +/- .0002 bearing bores, probably not going to fly.

Right Angle head?

Baseball bat to the knees of the engineer?

[mikechvz]

.010 tolerance on diameter

 

baseball bat sounds like the solution tho, thanks

 

we looked for a angle head bit trying top find one small enough for the length

We could sinker EDM them for you.

How I would recommend they get done. 5 axis with a Lollipop cutter would get part of it, but be real hard to get the complete hole.

 

Got to love engineers. I got me a piece of paper says I am smart and smart I is. :laughing: :w00t: :no

An ELTOOL head will handle that no problem.

^^^^^^  We were a little apprehensive first time out with interpolating holes with these heads.  Of course the sales staff says "no problem" but in real life it doesn't always work out that way.  In this case it was good with a little playing with S&F once set up.  We have done holes with drills hundreds, thousands of times.  Milling was fine once we had all feed and DOC figured out.  The "M1" head is the way to go.

all i can say is WTF!

We looked into these not long ago. They look pretty sweet, but I think they require high pressure CTS

Print it.

FYI, I will vouch for the ElTool coolant driven heads. We have just purchased another one for our Integrex. They work great and are a bit less expensive compared to mechanical heads. We drill and mill titanium with them without any issues.

If you feel more comfortable using mechanical heads than look into Koma Slimline. We also use these as well with very good results.

We use several of those at the time in bt-40 on a 4th axis vertical (tool change is not a problem). Drill, mill and surface. Shanks max out at .125" but never had issue. Used them for 3-4 years now.

If you can model it you can make it, right?   Reminds me of some of the programmers I know, "Hey, it compiled. What's the problem?"

[Brian Pallas]

It looks like a weldment.  Is it a weldment?  If it is couldn't you make the seperate pieces, put the holes in, then turn some shatfs to hold the plates in the appropriate posistioning while it is welded?

that would work, but no sir, its not a weldment

Have you asked the customer if it can be redesigned? This is going to be an expensive feature and it's possible the customer could easily modify their assembly. Telling them that feature will cost them an extra $$$$ per piece may motivate them.
