CNC mill conversion to plasma cutter
Hello Group,
Just wondering what the down side would be to using my Haas VF2 and mounting a plasma cutter to the quill? I was thinking of putting a 15 X 20 water tray on the table. This must be a bad idea because I can't find anybody on YouTube that has done this. I'd appreciate anybody's opinion. I don't have experience with plasma cutters but I've got a customer with a lot of smaller parts (3/16 thick 304ss) that just wouldn't be practical to mill.
Thanks in advance,
Bill |
Re: 1mm lead screws on X and Y axis... should I use threaded captures one side or both sides of the axis?
Thanks, Will probably just go with one as the sync, binding issues are not to be discounted. Yes any thread lubricants will act as a magnet for swarf hence the planned extra shield either side of bed, and a vacuum of course. Dom |
Re: 1mm lead screws on X and Y axis... should I use threaded captures one side or both sides of the axis?
I'd go with a single nut - if you use 2, you'll have to come up with a way to make one of them adjustable to ensure it stays in synch with the other one. I'd also avoid grease lubrication - it ALWAYS acts as glue for wood dust. A better choice is something like NEOLUBE that leaves a dry film of lubricant. (There are other brands; I'm familiar with NEOLUBE because the major free world navy that gives me retired pay used it.)

Don’t forget to put a special grease on the threaded rod it is called kluber grease and it never deteriorates get on amazon Show a full picture of the machine Regards Harko On Sat, Aug 10, 2024 at 10:38 AM Dom Baines M1KTA via groups.io <dombaines=yahoo.com@groups.io> wrote:

Might not be really clear so will try to take a photo...
but.... Y axis, threaded rod use to translate the stepper rotation to a linear motion.... but should I fit just one capture nuts to one side or one to both sides of the gantry that connects to the X axis (same on X and Z).
CNC will machine wood and not to hyper precision so not using linear rails etc.
Regards,
Dom

Re: Bridgeport CNC needs a new home
When a 15hp Cazeneuve hydraulic pattern lathe -- functional
but being retired -- arrived on a low trailer, I moved it off the trailer
and into my shop using a 10' 12" i-beam, many short 2by4s to stack
on each side, and an ordinary floor jack to lift the lathe, slide the
trailer out from under it, and lower it onto some 2-ton dollies built for
the event. Same setup was used again to get the lathe onto the floor. And
yeah, if that forklift wasn't so expensive to rent....

Re: Bridgeport CNC needs a new home
I saw a trick once that I thought was a good idea for
casters . The guy put hunks of PVC pipe around his casters , they
rested on the ground were not attached & were free to move .
So when he moved his machines the PVC would move anything out of the way that a caster wheel may have tripped on before it could reach the wheel. animal On 11/6/2022 10:39 AM, Brian McKenzie

Have crated several machines for transport long distance, lifted
locally by crane equipped trucks. For one expensive VMC purchased
in Australia, I travelled there to pack it myself by wrapping it
up with many sheets of 2inch thick polystyrene sheet, which I
later used for workshop insulation. The machine was then rolled
neatly into a shipping container, which container was then
eventually set down on my driveway, after a sea voyage that I
could follow online. -Brian |

I had to call around a bunch, and found out there were few outfits that had lift gate trucks anymore. We ended up renting a Ryder truck with a 2500 Lb lift gate, and took the head and ram off the mill to lighten it and lower the center of gravity. Sliding the mill off the lift gate and onto my basement floor was a big challenge as we could not get the truck lined up for a straight shot into the door. It required comealongs and lots of plywood.

possible to do this by yourself with some thought and the right equipment. Forklifts make life very easy, but are not essential (although if you can get one, do it). I'm using skates, a toe jack, a johnson bar and a drop deck trailer and just moved a mill yesterday. I use a chainfall to pull the machine up onto the trailer deck and then chain it down with binders and add a couple ratchet straps for good measure. If you're carrying a load you want it to be part of the trailer. I once saw a trailer carrying a backhoe flipped over and the backhoe was still attached even though it was upside down. I try to ensure anything I'm towing is fastened similarly. You need a proper vehicle though. I've carried 3000 pounds lathes in the bed of my dually pickup without issues. Towing 5 or 6 thousand pounds gross weight is not an issue either. Or, just look for a local rigger and use the universal tool: money. Sit back and watch them take care of it. I had a machine moved cross country and the local rigger took care of it from the trucking terminal to my shop. I just pointed to where it should sit. Didn't even break a sweat :-) Do make sure the rigger is insured and reputable. I once had a guy drop a 3000 pound lathe 3 feet onto asphalt when his strap slipped (no damage, although the asphalt gave a little). At least it didn't slip when it was 6 feet in the air.

Re: Bridgeport CNC needs a new home
WHen I picked up my new to me mill & lathe a few years back I rented a tandem axle uhaul with the high sides . I rented a fork lift for 4 hours & had it delivered @ a hour after I arrived at the pickup location . I lifted the mill from the top
& put it on a pallet that was in the trailer . Then I strapped
the mill down to the pallet & secured them both to the trailer
. Then I removed the top of the mill which was the motor , the whole head
assembly & the casting between the two . I had almost a 500
mile drive & wanted to lower the CG of the unit . I strapped
the top assembly to a pallet & strapped it in the trailer ,
& loaded the lathe . Made the 500 mile fine , though it was a
much slower drive than I usually drive . The next morning I
unloaded everything with my backhoe where it all has been sitting
for 2 years while I finished our new house . I hope to have the
machine room all framed up & ready to move into hopefully in
the next month . Not really much to moving one of these machines , just a TON of Common sense . good luck animal On 11/4/2022 5:27 PM, Tom Harrison

You can do it. Just ask a lot of questions, and go slow. Tom Harrison At 2022-11-04 06:45, Tim Goldstein wrote: You can have equipment like this shipped without crating.

Re: Bridgeport CNC needs a new home
Bridgeport Series 1 with 2 Hp 3 phase motor. 9 X 42 table with ball screw slides.
I’ve mostly only used it as a hobbiest, mostly making tooling, etc. I paid $5000 for it about 2005 and it had been retrofitted in its history with a Bandit CNC. The Bridgeport was manufactured in the late seventies. That system was designed for tape input but I didn’t have that capability, therefore no way of storing a G code program that I would manually enter in. Then realizing that the old Bandit system was no longer supported, for example if a card in the card rack failed, it would be useless. On Google I discovered the Linux EMC software available to interface it with a PC through its parallel ports, I successfully converted it to that setup. I kept the original power supply and motor driver boards. I have all the documentation for the conversion that I did. Acurite glass scales on X and Y axis. Engraving jig with motor is included. Kurt 5" vise 7" rotary vise Cold Air cooling gun Bejur spray mister EDM power supply and control box. See demo photo of hole through carbide in photos link. For photos they are available on Google MyDrive: https://drive.google.com/drive/folders/1dTATMW9DM6REIOg-c9RihZbmx4Uw8YnG?usp=share_link I hope you are close enough that it would be reasonable to see it.

Re: Bridgeport CNC needs a new home
I am interested. Can you send pictures please? Do you have a way to get it on a skid and in a crate, and load it on a truck? I can arrange the freight. What is the asking price? Thanks, Denis
