Just used this today. Glad these old forum posts are still availble!!

Hi

Need some help on a project here at work. We are roughing up some large 304 ss rollers ( 16" OD x 60" Length) by sending them out to be blasted. The results are inconsistent, at best. Does anyone here have any suggestions on a tool or process we can use here in house, to achieve the same result, while holding a decent tolerance on the OD? One of the guys here suggested knurling.... ?

Thanks in advance,

John

Hi

Anyone have any ideas on how to drill thru a plastic roller, 9.600 od, with a 2" dia. solid 304 SS shaft? We are currently using 12" long, 19/64 carbide tipped drills, but get maybe 2 holes max out of them. Feed 1., Speed 600 rpm, flood coolant, 2" R plane above part to blow off the chips etc.

Thanks

Hi

On the same topic, We're new to X5 (the company had us running MC8) and I'm trying to save my settings when I close the windows, so that they remain set when I close and re-open the program. Some of the operators here don't always double check things, and i'm betting this will become an issue, soon.

Thanks

Hi

I forgot how to set my preferences in MC9. Can someone refresh my memory, please.

Things like default tool offsets, libraries, etc.etc.

Thanks

John

Hi

I just ordered a multi point insterted 8-NPT threadmill, figuring that HAD to work.

We'll see.

Thanks

John

Hi

Trying (!!) to cut 3" - 8 NPT threads, 1" deep, 2 pockets, using MC9.2 and and OOOOOOOOOLD fadal with CNC 88 control, using format 1.

I know it's been done, because I can see the parts here in the shop, but I cannot find an MC or NC file ANYWHERE. I programmed it myself, but it output so many lines of code (over 1,000 for 2 holes) that I couldn't load it into the control. What am I doing wrong, and better yet, how do I do it RIGHT???

Again, PVC, 3" - 8 NPT using a boring bar type single edge cutter (measuring 2.072). Both pockets are 1" deep. No rigid tapping, or any of that fancy stuff on this machine....

Thanks,

John

Awesome, that's exactly what I need.

Thanks

John

Hi

Is there a formula handy, or someway to figure out the taper size to rough mil a pocket for a 3" - 8 NPT internal thread? I need to threadmill the pocket on a Fadal (Older than dirt...) using a single boring bar type cutter. Apparently that's what the last guy here did, but I can't find any existing NC files for the part.

Help...

Thanks

John

Using...

Mastercam 9

Fadal CNC 88 control

Hi

Thanks for all the input. I will definitely check on the oiling of the machine for rust, so far it seems to be in pretty good shape (for a 20 year old fadal, ha ha).

As for chips, MAN, this stuff FILLS the machine. I have started filtering the coolant drains, and that helps. I have to dump about 2 Barrels of chips per every 10 16" dia. parts!!

See Ya

John

PS-OLD ( I mean REALLY old!!!) fadals are a trip...

Hi

Just wondering if anyone had any idea what SFM I could use as a starting point for pvc and C-pvc??

My machinery handbook doesn't list ANY plastics.

Machining it on an old Fadal, with coolant, and HSS tools, programming in MC9.1

Thanks

John

Ha

Remembered my old password and login!!

Hope my post count is back....

Does this one count??

Hi

Just got my copy of X (Thanks CadCam), and have it installed, but with all the bugs being listed is there any benefit to switching over today, rather than waiting a little while before working with X??

What are the immediate benefits of X, to a novice user??

Thanks

John

Hi

Nevermind, it showed up the next day!!

It was slide, ala Jimmy Page - "In My Time of Dying", with a beer bottle. Nothing fancy, but it sounded cool with a lot of echo, and looked cool too. BTW, I DO NOT TAP and we still tune to 440!!

Later

John

Hi

Am I the only one here who has NOT received their copy of X yet?

John

Hi

I have a TREE VMC 840 with the dynapath 20, if you have any questions, give me a call or email. I also have a BUNCH of dynapath 20 manuals around here if you need one.

Good Luck

John

HI

I use them for slotting and finishing ops and always use coolant. These end mills kick butt!!

John

Hi

Dang, $545 is the cheapest I can find the starret version anywhere, by tomorrow. Ebay has them for around $150-$200, but then I have to wait, which will easily cost me the difference...

O'well, I 'll figure it out.

John

Hi

James - I got rid of the Mori, just didn't get enough work to justify the expense. Actually sold it for a small profit, too.

I don't even want to waste my time with Ebay, I figure someone here can use them, and the forum always helps me, so what the heck...

Thanks

John

Hi

Cool. Thanks for the tips. I'm going to attempt this sometime this weekend (if I can afford the level!!)

Thanks

John

Hi

I have a MAINTENANCE MANUAL for a Mori Seiki SL-20, brand new, an INSTRUCTION MANUAL for a Mori Seiki DL-20, also Brand New and 2 copies each of PROGRAMMING MANUAL for Mori Fanuc 6T and FANUC System 6T for SL-2 Operators Manual, these are pretty beat, but the info is good.

I am cleaning out the shop and don't need these anymore so if you need them, pay for the shipping and they're yours!!

Thanks

John

Hi

I've seen it done a few times so far, but wasn't sure if it was as simple as it looked. I made sure that the machine was placed on a single slab, so other than adjusting the leveling blocks, I should be ok.

Thanks

John

Are we required to pay next years maintenance, even if there's no version X yet?

Just wondering, 'cause I still have a LOOONG way to go learning ver. 9

John

Hi

We just moved a vertical mill to a different side of the shop, and I need to check the levelness(?) of the machine, any special technique or tool required? I'd like to do this myself, if it's possible.

Thanks

John

Hi

Thanks again. I will try these out and see what works best.

See Ya

John
