what cnc machine do you run?

[m016324]

I am curiuos what machines people actually run currently. We have quite a few machines in our shop but i usually run either a nakmura-tome sc250 or a doosan puma 700. i also run a bridgeport romi II every once in awhile when the other machines are busy. Let's see what you run

Old school Tree Journeyman 310. Almost had a 325 but somebody beat me to it by about 7 minutes :( .

Only one I have ever used is a Fadal 4 axis. Dont know the model off hand.

What shop is it? Im in ABQ too.

i program and run a nakamura tome super ntj 9 axis millturn.http://www.mmsonline.com/mag_images/090302g.gif

we just bought this recently with a makino a 66 horizontal with a 2 tier 10 pallet ,pallet stacker.
we also have some old haas machines.

i program the nakamura using esprit software.its still a nitemare

I work for accurate machine. Over by the airport. I think I met you last summer at the car crushing thing. You had a jeep on like 38s I think. You know nate I'm sure that's who i think we met though. I also helped build that Land Rover 110 on unimog axles that was at that event.

"i program and run a nakamura tome super ntj 9 axis millturn"

that thing looks cool by damn there would be a lot of stuff to think about on that thing. We have a coupld of mills with pallet stackers and separate setup tables, but our shop is pretty much divided between mill and lathe people and it just matters when you show up as to which you do. So if you start with mills you usually stay with them except for an odd job here and there

Gents,

I've got a Cincinnatti Arrow 500! Bitchen machine with 20" x 20" x 20" travels. PC touch screen control that is super easy to use.

the ONLY gripe I have is it's an air hog. I've got an 80 GALLON compressor and it goes off every four minutes! All it uses air for is the spindle oiling, seems excessive!

later,

i love my quickload servo lns barloader on our hyundai lathe.it holds 4 ft max.we also bought a 12 ft lns barloader for the nakamura.it will push up to 2.5 bars.it is not servo driven and it always pushes.
its an absolute pia to change liners for different bar sizes,(covered in oil),set the topcut position and set the end of bar.
my life was so much easier before we bought this nakamura.

also you cannot get a very good finish contour milling with it.u can get satisfactory results with a very heavy cut ,loading up the tool.the problem is the tangdrive system for the rotary tools.there is always a little slop in it.most of our parts require slight edgebreaks and fine milling which always come out shitty.some of the heads i use cost close to 10 grand each.(right angle speeder heads)
when they tighten up the preload on the bearings (right angle head bearings have to b looser than straight)they get hot and burn up.

we are wishing now that we had bought a regular b axis nachine rather than a turret style b axis.ours is faster because all of the tools are on the upper turret and it doesnt have to do a toolchange.the upper turret will go 91 deg in either direction and anywhere in between.this is even a programmable axis but even nakamura says how the hell are u going to program that?

oh well thanks for hearing me vent.
im setting it up right now,

2 Fadals
1 Quaser VMC with twin pallet
2 Hyndai Quickturn 15N
1 Mazak Quickturn 18N
1 Victor 25
1 Daewoo Puma 700
1 Mazak Multiplex 640 with robotic gantary
1 Mazak Nexus 250M
1 Old VMC known as the 500,

This is what my workplace runs

The Mazak Nexus 250M is a very nice machine, also is then Quaser VMC, the Mazak Multiplex is great when it is running, had a lot of problems in the first 3 - 4 months with the robotic gantry

[cherokeechief79]

hey bubs

your hyundais have seimens controls?

[bubs]

Mazatrol

They are exactly the same as the older mazak quickturn machines, just made in korea. Neither one has ever caused a problem for us.

[vegard]

kitamura my center1, 3, WJ, all with fanuc 6m, and one with 11m. old and can be a pain in the ass, but the big ones are stiff powerful gear drive machines, that will blow the socks off some newer stuff.

My Dad's Mfg Plant runs:
CNC Lathes-
Daewoo Puma 2500 SY
Mazak 15M
Mazak (little lathe, don't know the model)

CNC Mills-
Fadal (something or other)
Haas (Brand new something or other)

The only one he regrets buying is the Haas, and it's only about 1 yr old. He totally loves the Daewoo.

[cherokeechief79]

we always make fun of our haas machines too!
even though we have several

How old of a Fadal are we talking? I played with some machines equiped with Fadal brand controls and wouldn't trust it to machine dog s***.

It's probably 10 years old or older. It works pretty well for the applications they use it for. It hasn't really caused many QC issues that I'm aware of.
I'm not really familiar with the controls on it. If I need to make something I do it on one of our old bridgeport mills...

What about the controls did you not like ?

[Captain Ron]

Me too, every week on the way to the bank. They are a great customer... they shipped over 700 machines last month.

What CNC machines do I have?

Why, Amadas, of course. :flipoff2:

PS: Fadal is a customer too!

[Goat]

What about the controls did you not like ?

Their motion tracking is really poor...trying to mill some aluminum with some authority is hard to do. Feed rates above 50ipm are for roughing only on those machines.

I'd be lucky to mill in the range of 70-80ipm and hold a good surface finish with some acceptable tool life. Comparable machines get into the 120-150ipm range and 3x the tool life with a superior finish.

Being able to change the servo gain on the fly is a testament that the control is poor...using M92 to up the gain so the machine tracks right at higher feeds, just makes you cringe from the banging sounds that you hear. M92 = hello new thrust bearings, forget M93.

The 104D control is something that fadal should have never released...

There is a reason the new fadals come with the option of Fanuc sevos and control.

If I was given the choice between Haas and Fadal, I take Haas...at least the service guy shows up when you need service.

2 Hardinge GT SPs
1 Hardinge T42
1 Hardinge Cobra (popcorn maker)
1 Daewoo Puma 240 (lemon, manuf is replacing it)
We program without software, been doing it for 20 years.
Fanuc controls

Have run;
Agie wire EDM
Brothers tapping maching (CNC mill)
Hardinge C42
Bridgeport BOSS5 (old)
Some other odd machines, Bandit controls and conversation line programming.

[Magoo]

Anything you put me in front of :D

Right now I run a Bridgeport and on old Cincinatti Millicron POS. It sucks working for a shop that's too cheap to heat the place let alone get decent equipment.

On the plus side, I run what I want when I want, and noone is looking over my back to see if I'm done yet :flipoff2:

This is all pretty minor league compared to the rest but:
I do the nesting/programming for the cutting table at work. Its a Koike-Aronson table with a Hypertherm HPR-130 plasma and Hypertherm D80 control. 150ipm quality cut on 1/4" steel. Super user friendly, windows based. If they added an ethernet card I could surf the web from the control. I could "program" and run it without knowing g-code existed. I only get to play with it when my operator is sick.

In the past:
-ran a manual lathe converted to CNC ID grinder, used 150k rpm air spindles with dental drills for tools. Parts about .150 OD
-ran/programed a small Mazak lathe with conversational programming. machine came close to killing me, literally
also played with a Bridgeport BOSS5 a little when the mazak was down.

BTW, couple of anybody know what an old cnc knee mill goes for these days? We could keep a beater machine busy all day if I could talk the boss into it.

I have a Milltronics VM16 in my garage
