Hey everyone.
So I am trying to find the best way to organize all of our tooling in our CNC department. We have a fairly large tool crib, but it is currently a total mess. We have 4 setup people, all with their own tool boxes with many random boring bars, drills, collets, etc inside. But we also...
Hey everyone. Thanks for the replies. I have done my research, passed it up to the higher ups to see what they decide. Not going to go with any homemade things, because production is quite high. About a couple thousand a couple times a year.
We will either go with the pot chuck idea, or end up...
Hey Everyone,
Thanks for the quick and thought out replies.
Mike I like your thinking about a pot chuck, something that I completely gapped on. I believe that something like that would work, except that we are worrying about the part slipping at all. There are 4 cast tabs on the ID near the...
Hey Guys.
I have a Brass Casting that needs to be turned on both faces and the OD. The ID is approximately 4" (has a 1 degree draft angle though).
I was going to just use an ID chuck (with steps so I can do the back face), but have been told that no chucking marks are allowed (which makes no...
Hi guys
This is more af a preference and job specifice thing, but when picking off with a sub spindle do you usually have the spindles turning (synced of course) and/or what are the scenarios/advantages to spinning rather than not.
Thanks

Hi, when looking in a tooling book, you have your standard 6 different coloured boxes indicating the type of material being cut. P-Steel M-Stainless Steel K-Cast Iron S-Heat resistant super alloys N-Aluminum H-Hard Part.
I use alot of Copper, Brass and Non ferrous materials and just wondering...
Just to let people know I have been running ST1 now for a few weeks with Windows 7 and other than the 2 small inconviniences I stated above, everything still is running great with no other flaws yet.
Thanks

Hi MRSSPOCK
Again, I didnt have a specific part in mind but tolerances usually run from about .002 to .010 total depending on the part. So not overly tight, some more than others.
That was also my train of thought using 1 centre drill for the first drill and none after that. But wouldnt this...
Mike- I like your thinking. Give it all it has. I just wasnt sure if this would, in your past experiences, dramatically decrease the tool life, or have any other negative effects. Or else everybody would always take the highest recommendeds for roughing.
Saber- I never had plans of going...
Hmm, never really took into account the power behind my axis's and spindle. I dont believe that any of our parts will be a problem because most holes are smaller than 3/4" but if any larger jobs come up this will be definately be handy information.
Thanks Bill

Just a general past experiences question. I know this has many variables but when machining, If the ISCAR book gives a range for feedrate and depth of cut for an insert, what percentage of that range would you use when roughing. Mostly turning, but milling answers are very helpful too!
Ex. CNMG...
Saber, we do use step drills for alot of applications, this was for all of the times without. Thanks though.
Mike, this is opposite to how I would have done it, trying to reduce how much force that I need to push the drills through, but that is like you said the manual way of thinking and your...
Hi.
When Drilling multiple holes on a lathe, all to different depths, is it always smallest hole to largest hole or is it sometimes beneficial to start with the larger holes first to save the smaller drill or for any other reasons (concentricity, finish, etc)
Thanks
Jordan
So a few minor inconviniences to report. Both on drafts.
One is the diametrical centre mark only leaves a very small centre mark, wont go full size.
The other is that new sheets keep slowly getting added with different templates, but a quick delete and were off running again.
Seems to be running just fine now, that was the only problem I encountered before, I have done a few things in draft as well, all seemingly fine. I will keep you posted if I find any more glitches but so far so good.
All I did was take Pellaken's advice.
