What RPM and DOC/WOC were you using?
Thanks!
[/QUOTE]
I am running a 3" WOC at 0.055" DOC, 40 IPM and 2500 RPM. The finishing pass is the same recipe with only 0.005" DOC.
Not sure what you mean, can you elaborate please?
Done and done, now we wait...
I am hesitant to modify the post processor because then I have to manually check for updates and make this revision every time. Does anyone know if Tormach provides the post processor for Fusion 360...
Has anyone else been bothered that the Fusion 360 post processor for Tormach always outputs G54 as the work offset in the first line of code after the tooling comments regardless of the work offset...
So what did you guys think of your new shell mill? I am still loving it and I haven't had any issued with storing it in the ATC during production runs!
You did that all in the high belt position? That's great!
I am interested in switching over to a formed tap given how this discussion has gone but I am worried about the torque of the machine. Can anyone chime in here to let me know if I could tap 1/4"...
[QUOTE=Steve Seebold;2156026]I tap a LOT of 8-32 holes and the way I do it, I haven’t broken a tap in over 40,000 holes.
Is the idea here to let the pitch of the thread drive the tap through the...
I am using a spiral flute tap:

For flood coolant I use 251C and honestly it cut really well. I do have Tap...
That did the trick! 500 rpm and a larger retract height! Thanks everyone!
I guess I didn't give everyone enough information. I tuned the VFD for the RPM that I was using with a laser tachometer. This is a through hole so there is plenty of chip clearing. I have a...
Here is the g-code:

I just bought the Tormach Modular Tension/Compression Tapping Head Kit:

My shell mill came with a screw threaded into the tool.
I am pretty sure I got the last two collars from Tormach. They said they were on backorder because of quality issues but I called and they found 2 good ones and sent them next day air. Great customer...
I hope they speed up this release because my operator just experienced the same issue!
Nathan, I have Mitee Bite locating rails with 0.100" height above the part surface on two sides of each piece of stock. This way I am able to machine the entire perimeter of the part on the first...
Well IMT made some great suggestions and I was able to achieve 6.6 in^3/min MRR! I removed 3 of the inserts, ran a roughing pass full 3" WOC at 0.055" DOC, 2500 rpm and 40 ipm. The finishing pass...
I made a custom pallet that uses miteebite clamps. My stock starts at 3/4" but my final part is 5/8" thick. I saw the exact same finish when I was testing in a vise so I am confident in my...
Well today got away from me and I didn't get a chance to do any more testing. Should be able to get something tomorrow!
I am using the polished carbide inserts for aluminum:

I will definitely give that 0.050" DOC 3" WOC a try but I already ran the other recipe and I was not able to hold 20 ipm because the spindle bogged down on me. I could only get about 15 ipm.

Well today I got to play around with the new MariTool 45 deg shell mill (3.15" OD) and it is really nice! It took about 10 iterations to find a good recipe for what I am trying to do. As a...
The new tool showed up today! I am going to put her together and I'll probably do a short video with some test cuts.
I hope that going to a face mill reduces the shock on the entire spindle system compared to a fly cutter. I am worried that the large tool diameter puts a significant torque on the R8 collet that...
Wow, I must have some bad luck because today I broke my first superfly, and in the mean time it spun the R8 collet in the spindle and mangled the key that prevents rotation of the collet. Has anyone...

Do you mind elaborating on why you would choose the 25mm center cut insert end mill? Are you getting really good material removal rates? Is it a stable and rigid tool?
Thanks!
