fenn do you have any experiance editing a post processor for MC?
sed__ nope, never used a post processor myself, just heard that's what worked for others
never used a post processor?
you write all your g-code by hand?
yeah, that's why i dont make much stuff
omg, my neighbors are high
brb visiting maddash's neighbors
too late, they're finished
they skinny dipping or something?
no, just giggling excessively
woohoo, i just chop-chopped another ap
no FBI affiliates here, right?
you are being monitored
NSA is reading everything...
I wonder if they care about my activities...
does anyone own or use a large lathe
large = ?
something like 30"x120" or larger
best Ive done was a 24" - and that was long ago and far away
top speed of 470rpm
but probably too low on rpm to be a valid thing for what i'm about to ask
i've seen a bunch of those size lathes, 25/30/35" swing
that will spin about 1k rpm
or a bit under
so I was wondering if there was an advantage to running smaller jobs on a bigger machine
or if it was just too awkward
it was a PITA
what parts bothered you
I used that monster to make a bunch of 1/2-20 studs
why did it suck, though
for one thing you did not want to get in close to the work with a huge chuck swinging right next to you
a 24" 4 jaw is a lot of iron with plenty of ways to grab you
yeah, we have a CNC with a chuck near that size
it is quite frightening to see it move at 3000 rpm
but i can always put a smaller chuck on the thing, like a 12"
they mainly had 3 or 4 jaw chucks - hated to swap them out cause its a 2 man job to lift them out of the machine
that's a bear man
but was there anything about the machine itself
I did get to use it with a 5C adaptor once - since we were going to be mounting a faceplate to bore some tooling plates
so I put that up between jobs
I like a good sized machine - they cut smoother with all that iron to damp things
same on CNC
the Leblond at school is a 16" swing
want a 10" chuck and a big turret
but i'm kind of curious if there's a functioning difference between working on a 16" machine versus a huge 30" machine
and min 2" thru the draw tube
lag and inertia
harder to stop on an exact Z
yeah, but most of our stuff have hard depth stops
makes repeatable Z pretty easy on our stuff
16C doesn't mean big
only one machine is bar fed
what do you mean?
have some tiny Mazaks that use 16C collet chucks
bigger than a 5c
all our machines take 16c
even the super tiny ones, i know
machine is like a 5x5x4 cube
but we have two that take 25C, and those take 2.5"
yeah25 is getting up there
easier to set than a chuck
we use those on the inertia welder
too bad they're expensive
I think those Mazaks are like 3hp
my favourite lathe at work is our big Mori Seiki
lots of room to work, can stand inside the machine to change stuff out
ooooh the Rolls Royce of Nippon lathes
it really is
all our other lathes drift over time except that mori
and the mori is real old
turns stuff more accurately than the other machines, and hogs a lot harder
easy to set up, easy to prove programs on
to bad they sold off all there manual machine stuff to there Korean subsiderary Hwacheon
that sucks a lot
but manual machines don't have the profit margine of CNC
yeah years ago - early 90's or late 80's
the only manual lathes I'm really familiar with are the old brands
modern stuff I only know of Sharp, Birmingham, Ikeagi, Mori, and Mazak
and we don't make any in the U.S. anymore
Harding makes small stuff - nothing you'd want to use on anything over 6"
if I had to buy a manual machine I'd rather pay for an old American or Axleson and get it refitted
for a business, anyway
I'd like to find a LeBlond - simply because they were designed to have feild replaceable ways
just bolt up a fresh set and the bed will be good as new - hopefully the gearbox has been treated well.
I like the Mori and Okuma manual lathes better - they run much quiter - but you are out of luck if anything goes wrong - they have been out of production a good 20+ years
Makino dropped the LeBlond lathe in the late 90's
unfortunately from what I've seen, finding a leblond is easy
in great condition, no less
they're just 5k for a machine with no accessories
so spares might be found
Leblond parts are still made
even from the very first conehead lathes
call them up, they will either send you the drawings for the part or make it for you
far as I know all leblond stuff was phased out before Y2K
it is phased out
you can't buy new lathes
but they still support all of the old gear.
it's not cheap, but they still support it if you MUST have a factory part.
I need a building to put machines in
there are guys on practialmachinist with details on how to get stuff from them, and I believe my school also gets stuff the same way
haha yeah =(
are you using a garage right now?
I get offers of great deals I have to turn down cause theres no place to put it
house has no garage
I have my big mill in my kitchen
and thats just to keep it stored in a temp controlled area
I was going to buy a ranch and move when I ordered it
I backed out - company was doing 'strange' things that made me nervous.
did not want to start a new mortgage and find the plant was closing
and my gut was right
seems a deal went thru and we are in a buy out from our parent company
so plant is not closing - but is forming a seperate LLC
is that good news for you or bad news?
but it means we have to re-apply for our jobs, and all new benefit package has to be worked out
and that re-applying thing might be a blessing or a curse, i guess
has yet to be seen - if not hired by the break away LLC I will get a severence pkg from parent corp
some are thinking of taking the severence package and applying later - like an extended vacation
that would be nice
provided they can get their jobs
i've considered trying to find a better paying place, which would be very easy
but the place i am working now is giving me experience and they're willing to take me on field trips
they lost most of there best people in the last year - management was cutting corners to horde cash for the buyout - and pissing off people in a bad way on how the did things
I'll have been there 3yrs in OCT
i thought that was some department
and I'm up to about 6th in day shift seniority
thats counting down from the machine shop production manager
how large a department
24 people on days - 20 on nights
but we are understaffed at those numbers
and they are hiring - plus putting on a crew of 7 for a weekend skeleton shift
what kind of jobs do you guys do
start with extruded AL tubing and form end journals - cut to lenth, paint the ID, finish turn, grit blast, teflon coat, final caotings - silicon moldings, and pack for shipment
make fuser rollers for high speed laser printers and copy machines
about 4800 a day
you mentioned this
same part familys - over and over
i'm familiar with that kind of thing =(
wish I could go back to doing proto type work - but the work flow isn't there - no money in it.
we are fortunate in that our product is expensive enough that prototype work is profitable
so we do get that kind of thing through the shop if a person wants to work on it
I used Solidworks, and Bobcad/cam plus the built in Hurco conversational as well as the CAM output for the Mori & Okuma mills.
I used to go to lunch with a client and go over print details - or even a rough sketch
then drop buy with the finished part by 4pm
That is what really built my rep - same day working parts
but most of the customers we had have gone overseas - not much local work
so now I push the green button making fuser rollers becuase the work is steady and enough OT to choke on.
there is good work ing other cities
but I'm not sure I want to migrate
there is still enough proto work to make a good sideline - just don't count on it being steady
does the g43 h* setting affect the coordinates returned in manual mode?
maddash: in emc or what
