New Toy CNC Lathe!
« on: June 06, 2008, 09:12:24 AM »
Well guys,

I finially got the new CNC lathe up and running.

She's a Prototrak 16" x 30" with so called conversational programming.



I've been fooling with a few artillery projects between real jobs as I get up to speed.

Here's a little barrel that has about a 4 minute cycle time.



That dosen't include drilling , making the trunnion, silversoldering and cleaning them up.

This one I did on the mill. It has eight sides.



Here's a couple mini mortars in 303 stainless.



Here is the solid model of a , dern I forget the name of it, a "smasher".



This shows the program moves, rough and finish cuts, for the above with the cycle time of 2 hours and something.



That will be about 12 inches long by 3 inch diameter from a piece of 3" crs.

When I say "Conversational", this program has seventy some lines including rough cycles.

Anyone have anything in this range that you need (want) to have made?

Here's the eight sided one on a garrison carriage to be compleated.



More later.

Looks like fun.    ;D

Too bad it is only 30".   ;D

Nice!!! The things I could do with one of those.....wish I had one myself. I've never ran a Prototrak but have ran various others with conversational programming...mainly 5 axis Mazak's with onboard "Mazatrol" capabilities . It's amazing how fast you can program complicated parts with these machines.

 Brings back memories...

 I used Southwestern Industries "Trav-A-Dials" for years and knew the man who manufactured the first production brackets to mount them on various lathes.

 I operated their first model TRAK CNC Bridgeport mill retrofit machines when I worked at McDonnell Douglas.

 I was at the Southwestern factory when they were assembling their first batch of CNC lathes.

 I arranged for the purchace of the third DPM mill they produced for the company I worked for at the time.

 Good machines, and a good company.

Andy,

I can hardly believe my good fortune!

George,

Right, my equipment is never big enough.
I have a 54" right behind it, but that's an old manual
Pratt and Whitney.

Six Guns,

Prototrak, and a host of other companies were sued for
using the "conversational" description.

Seems it's a trade mark of IBM or something.
Conversational dosn't seem so conversational when you have to
input seventy some lines of code for a project.

Still better than g and m coding!

Victor,

Nice to hear some history on Southwest.
I learned myself how to run their mills in about a week.
Very quick and powerful system.

Course the day after I put the money down on the lathe for home, 
the Prototrak at work crapped out.

That gave me a warm fuzzy feeling!

It was a spent x axis drive motor. That is now fixed.

Dan,

They have various converters avaliable.
One uses cad files.

The machine is supposed to be able to import a Fanuc 6 coding,
or convert files form other machines.

These are options for $$$$.  Have to talk to my salesman to get the best
option.

I may be able to get a post processor for the software I now use at work (Mastercam).

Mastercam is really high per seat.

CNC lathes are fun. When I got mine going I kept going smaller and smaller and rounder, all without steadies, until it got quite ridiculous  ;D



Then I did CNC milling, now working on CNC plasma for fancy iron cannon fittings ;D

Squire Robin,

That's a neat little part.

I'd guess you started with rather oversize material and finished as you went along.

Here's Sundays progress.



I do the back end first cause if I mess up, I can cut it back and make a shorter piece.

Once the holes in there, you have a nice piece of pipe.

Had to program a finish cut both ways.



Here's the finished (almost) carronade in the model above.



This model came from a cannon plan on ebay.

There are quite a few plans that are old reprints from magazines on there at any time.

More progress on the swivel gun.





Work is really hectic these days.

Don't believe it took this long.

There's also a bronze Handgonne in the foreground.
