It will not. 63a has a larger "taper" dia.

Mike

Jaydenn is describing the way I do it. Requires a test bar but the most accurate way IMO. 

Mike

We've got some Robo's doing somewhat aggressive milling on 4140 forging's 24/6 and they just keep chugin along.

Mike

I would thread mill that. Coupled with a pre-setter (allows you to set off the pitch) thread milling basically takes any risk out of the equation.

Mike

Everyone knows you aint cool unless you're on Emc

Mike

 

We have serious limitations on space and getting a machine in.

 

Our hallway is 93 1/4" clear access and the door frames are 6ft wide.

I got ya. If your going to go BT30 drill tap machine I would probably lean toward fanuc. Even if a little lighter duty, (not by much if any depending on model), they are very reliable, fast and very accurate for a machine with out a chiller. Plus I would much rather have a 31i instead of a Brother control (we have both).

Mike

I think the Brother is a little more "Heavy duty" than the Robodrill but I if I needed to do any real milling I would stick to a 40taper/HSK63a machine. We have over 20 robodrills here and while they are awesome/accurate machines, there are limits to a BT30 interface. I would go for:

Makino PS95

Matsuura VX-1000

Okuma 

Maybe even a Doosan.

Mike

We, (and a lot of other people), use a tool pre-setter (camera) to measure tools non-contact. Very accurate and you can check a lot of other things like dia, runout, angles, and radii to name a few. The only way to go IMO. A decent one will set you back 30K though.

Mike

I've pushed a 2in indexable drill on a 2000SY no problem. 2.875 may be possible on your larger machine. However, I would do like others have suggested and either drill with something a little smaller and bore, or helical open. The problem with milling it open is your live tooling unit will not do well with a tool that can do this efficiently so it will most likely add an operation.

Mike

 

 

as long as you can assign tool numbers to pockets.

This is why we will most likely won't buy any new machines that cannot do this.

Mike

We handle it the same way as Bob. It's some work starting out but after a few months youll find that your setting up way less tools and programming way fast. Much safer too IMO.

Mike

Possibly higher RPM of smaller tools causing thermal expansion of spindle in Z axis? What is your process in touching your tools off? Using a presetter for all tools I haven't really noticed this.

Mike

We just brought in an LB-3000 w/ Y axis for our tool room. Great machine so far.

Mike

Interesting read...

Mike

U-Axis head will be about a 35K investment for an HSK63 sized machine. I am working on a project that uses a couple of them right now.

Mike

Pro P is just a Fanuc Oi. MPmaster will work well but Postabilty would be able to dial it in for you if you want.

Mike

If they can, I prefer customers give us native solidworks or inventor (which we have). If not, step is the way to go IMO.

Mike

Verisurf has a MBD product. I'm not sure what formats it can read in though. Maybe Ron will chime in.

Mike

I've bought a couple and have a few more on the way. Very solid accurate machines with good support. However, I don't think you could go wrong with Okuma or Matsuura either. 

Mike

 

 

 ZIESS should be used

Why? He knows this is a machine tool probe with accuracy of .0002 at best right? We have all Zeiss CMM's and don't even buy their styli. I believe we get them from ITP. I would try to go ceramic if you can. That way it just snaps off at impact and you don't run the risk of making bad parts because someone bumped the probe in the tool magazine or something and bends the shaft without realizing it.

Mike

 

 but it could also reject parts that are actually good. 

 

QC guy should like it then..  

If the drill is one effective flute, you are doing pretty well on feed rate. Surface footage not too bad either. Maybe look at a replaceable tip type (like the Iscar Sumocham), or solid carbide. You will get a way higher penetration rate. 

Mike

Now we're cookin!

Mike

The AE's at Renishaw that I've talked to wonder the same thing...

Mike

Yasda is solid but ya have to go through Methods.....
