Finding center without DRO
Great answers guys. Sometimes it's so simple. Neither one of us have much experience on the boring mill so sometimes our brains are overthinking simple things. I'll speak to him in the morning. Thanks for the replies. Cheers. -

Finding center without DRO
Good morning fellas. We have a part that we are machining and our DRO on the X axis is broke so we are using dials in the meantime. My question is, we have a half moon type part (picture a half pipe) that needs to be bored on the boring mill but finding the center of the X is proving... -

torque specs 1-3/4 thread
Awesome answers guys. We have determined that because of the application it is, that we do not have to have an actual torque value, so we just tightened as much as we could. I had forgot to mention, if it matters at all, that there were 1/2" thick MS washers used as well. I originally budgeted... -

torque specs 1-3/4 thread
Good morning. I'm trying to determine a torque spec for some bolts we made in house. They are 4340 HTSR material and are 1.75-8 and they are 16" long with 4.5" threads on each end. They are retaining bolts holding 3" thick plates together. but I am not sure a torque I should use. Before I... -

Large Buttress thread
Yes. Internal MD of the mating part was measuring 11.516. The nut was non measurable on the OD -

Large Buttress thread
Positive it's 1 pitch. It's only a single lead. That was the first thing I thought as well when I looked at it. I'm not positive it's imperial. I just wasn't sure what metric number it would be. 292mm ? Sounds weird. It's definitely 1 pitch though. We scanned it at 1.001 pitch. -

Large Buttress thread
I'm not cutting it with a profile insert. I'm using custom thread profile in Mastercam. Basically a 3D threading cycle to create the profile. -

Large Buttress thread
Hi guys, we came across a part we have to make for a customer and it has a massive buttress thread on it. The part was pretty destroyed and threads folding over, however I was able to gauge the profile at the bottom of the thread cause it wasn't damaged. (We used a 3D scanner) I basically got... -

HSS support calculators
Yes sorry, it's a large pc that will be partially on the mill, but the remaining end will be off the side supported by the legs. They will be welded to the bottom of the part. Straight down force. We need to machine the shaft areas down. I'm putting it on the boring mill and sweeping around to...- Hertz

HSS support calculators
Good morning, I'm trying to find some information on strength for HSS tubing. I'm using it end for end, its 5"x5"x3/8" wall and its 36" long with a 1" thick welded plate on the end. I'm trying to calculate how much weight that can suspend before failure but I can't seem to find a calculator for...- Hertz

spindle warmup Meldas 60
Good morning, I'm trying to write a daily warmup program for our small mill for the spindle, however I can't get the time to dwell properly. This is a Mitsubishi M60 control and while I thought G4P120 would dwell for 2 mins, it doesn't. This is the code I'm using. S1000M3 G4P120 S2000 G4P120...- Hertz

Machining Nitralloy 135
Good afternoon everyone. As the title says, I have a job here to make a part from 2" round Nitralloy 135. I've never machined this material and I was wondering what it compares to for turning? I actually need to drill a 3/4 hole through it and then, turn the diameter, and then bore a c/bore on... -

Another coolant thread. Keep using MB50 or change.
I don't see it like you do. What I take from his statement is that the coolant is drawing the oils from your skin. ALSO, drawing it from the coolant, so that you can skim it off. That's what I understood.- Hertz

Thread RPM
I was cutting M36x4 4340 on the CNC. I had went with a slower speed of 350 RPM to start because of slight chatter, but as I got closer to size, the chatter was stopping, however the insert had excessive wear on it.(I naturally thought the sfm was simply too high), but it still did it even at... -

Thread RPM
Good morning guys. I have a question. Might be a dumb one, but when threading on a lathe, what is harder on the threading tool, higher rpm or lower? I ask this because the feed stays the same obviously, and I was wondering if a slightly higher RPM would be less pressure on the tool or more for... -

ME ThreadPal - easy access to thread data
That's the site I originally went to. Try to click any of the links and it gets 404 error. -

ME ThreadPal - easy access to thread data
I know this thread is old, but is this program still around? Back in this day, I remember purchasing it, but when I try to go to the site now, it kicks back a 404 error. -

Potential New machine
We do any and all mining projects. Mainly though, we specialize in crushers, and not just local, but all of Northern Ontario.- Hertz
