We are a fairly large shop doing a lot of aerospace work and we recently got our first full 5-axis machine, DMG-Mori DMU70. Using it as an opportunity to break away from our normal operating procedures, we invested in dedicated tooling for this machine alone. These tool holdlers will not touch another machine (unless we get another DMU), and no other tool holders will touch this machine. We have a lot of old should-be-retired tooling floating around the shop, and one of the big recommendations I've heard from many different people was to not 'contaminate' our new machine with old and poorly maintained tool holders. On top of that, I do believe that to a certain degree you get what you pay for (as long as you know how to use it properly!), so I spent more for some quality holders.
Got a tooling certificate through Ellison when we purchased the machine, so I got a lot of Lyndex-Nikken SK collet holders, a couple milling chucks, and a few end mill holders. I held my ground against all the nay-sayers "wasting your money, doesn't make a different" people in the shop and have had to condition a few guys programming, operating, and tooling up the machine to get on board.
All of the sudden a crazy hot job with 3!! different tight tolerance bores comes up, and guess who doesn't have 3 fresh boring heads to use? This guy. So only second job on the machine and I already had to break my commitment to isolated tooling. Whatever, what's done is done. So I need a solution for boring on this machine. The reality is that we are a job shop and 25-50% of the work we will be running on this machine will be first time and short lead, I really need flexibility but I also can't go out and buy a whole set of boring heads for one machine. I'm looking to get the fine adjuster .00005 increments, I'd even consider looking at the digital boring heads if I can justify it with reduced setup time and reliability. We've currently got 2 Walter B3230s, a UN5 and UN6, gives me a total coverage of bore size from 2.165 - 3.543. They worked extremely well for a job that we purchased them for, this job will eventually end up on the new 5-axis and so will these boring heads. I would have to spend a ton on boring heads to cover all my bases. Could anybody give me some recommendations on a solid boring head or 2 that I can do a lot of damage with? A rep selling some wohlhaupter heads dropped a brochure off a little while ago and they seemed to have a pretty good "starter kit" type of modular set. Where else might I want to look?
