3 Axis Vertical recomendations

[DavidB]

cincy k what are the feelers like with 3D surfaces have you got AICC or AICC 2 ?

 

Have you got the OI-MD controller. Do you have Manual guide I?

[cincy k]

It does reasonably well. I have AICC 2 on both machines with the Oi-MD. I typically hold my total surface tolerance to .0002" and stepovers to around .004 with say a 1/4" ball mill and have never had an issue. If you're going to be doing strictly 3D stuff or a whole lot of it you'll be better off with a 31i or nicer control. They'll process the data faster. But if you don't need it don't pay for it.

 

I don't know if I have the manual guide. I do everything in Mastercam.

[Newbeeee™]

^^^manual guide is not worth a (insert suitable derogatory word here )

Siemens shopmill on the other hand...

[DavidB]

If you have a 8.4" monitor you dont have Manual Guide I. Manual guide I has the 10" mointor and a FULL key pad and 7 buttons under the screen.

 

Do you use the card reader or did you get the data server for your large programs?

[cincy k]

No manual guide for me. I just use the card reader for all larger programs. If i need to start in the middle of a large program I put a main program in memory to call subs off the card. The programs on the card are split at each tool change.

I like the Manual Guide i INTERFACE. The programming is a bit cumbersome. I've NEVER been a real proponent of programming at the machine anyway.

Yup - talking about the manual guide grammin. Soooooooo long winded and clunky.

And yes, prog at the cam system and let the machine make you money while your programming.

[DavidB]

So you can have a Fanuc OI-MD with AICC 2 and no Manual Guide?

It might depend on each machine tool builder. Some reps are saying you must upgrade to Manual Guide I ( 10" screen and FULL Alpha key board) to also get AICC.

 

Nice to know you can get AICC 2 on the standard OI-MD controller

 

The Doosan does look good with the 31i as standard along with AICC standard

Doosans also use the 0iMD.

That control uses the same architecture as the 31i Series,

It really depends on the machine and what was ordered from the factory.

I had a good look at the Doosan DNM 500 around $125k and the 650 around $135K today.

 

They come standard with AI APC (Advanced Preview Control) 20 Block preview.

The reseller in OZ brings them in with the option AICC (AI Contour Control) 40 Block preview

There is another option AICC II with 80 Block preview.

 

I'm wondering if the 40 block look ahead will be enough??? I'll run a test cut on it.

 

I'm looking at the Makino PS95 on Friday.

[Newbeeee™]

If you're surfacing but with G2/G3 etc (ie arcs) then 40 will be fine. We do it quite a bit with no issues.

If you're mold and die and everything is G1, then I wouldn't think so.

Get the 80 Block preview if you plan on doing a lot of 3D programs.

40 blocks is plenty for 2.5D but you always want to look ahead as far as possible.

For 3D, 40 Blocks is nothing.

That said, if you use the filtering in Mastercam properly, you would probably be OK

but always better to have more look-ahead than you need.

Have a look at the Okuma Genos M560V.

Great machine, even better price tag.

[DavidB]

Great machine, even better price tag.

 

The Okuma on the USA web site starts at $119K.

So in OZ that will be over 200K

 

Only 460mm in the Z axis ????

Question Newbee why would mould and die not use arcs?

Still a great machine. And do you need more than 460mm Z travel? We have an Okuma MB56VA and that has 460mm Z travel. I can't recall ever needing more

[Newbeeee™]

Question Newbee why would mould and die not use arcs?

I *think* that for pure accuracy, G1 (with very short line length) gives the best accuracy.

Tim and Foghorn would be better to answer though.

[Matthew Hajicek - Singularity]

There's also the possibility of the control interpreting an arc weird and going the wrong way leaving a gouge. It's only a problem on some controls, and one in a million even then, but you could have a million arcs in a mold.

This is thrown a spanner in the works.

I've come across a second hand Hardinge Bridgeport GX1000 with a 4th axis rotary. Year is 2010

 

Used Hardinge CNC Machining Centre:

 

Hardinge Bridgeport GX1000

Installed Jan 2011

BT40 10,000 rpm Spindle

1000 x 540 x 540mm X/Y/Z

Spindle Chiller

22kW Spindle Motor

30 m/min rapids,

30 Tool Swing Arm ATC,

4th Axis Drive + 250mm Rotary Table

Chip Conveyor

Fanuc Oi-MD Control

 

Its a big saving over the new machines I have been looking at.

 

Can anyone comment on the Hardinge Bridgeport GX1000???

 

Thank you

[Newbeeee™]

Ask whoever if this is a Quaser made cnc (Taiwan - they make for HB with a badge on).

If it is a Yang made m/c stay away.

If it is a Quaser - I'd snap their hand off.

Matsuura have got a deal with them now and they make the 1metre and 1.5metre machines for Mats.

HTH

[DavidB]

Thanks for the heads up Newbee I'll ask the quetsion.

Cheers Dave

 

Oh a little more info I found out

 

The Control Storage Capacity is 512KB

It has a Compact Flash card for drip feeding larger programs in.

From the machine information I have this machine does have AICC + Manual Guide i

 

I'm looking at the machine on Monday morning anything I should look for?

[Newbeeee™]

funnily enough I was at the UK distributer today of HB loking at a Feeler 510 drill tap (another thread... )

They are bloody well built the quasers - stout linear ways and big head castings with not a lot of spindle poking out - like matssura/mori etc

The D control is the latest and very user friendly

[DavidB]

This is the reply I recieved re the Hardinge.

 

This machine is a Hardinge Bridgeport made at the Hardinge Plant in Taiwan.

There is no longer any association with Yang.

Hardinge USA bought the Marketing Division and License from Bridgeport in 2000

 

Quaser were building some of the Hardinge Bridgeport XR Range but Hardinge Taiwan now build these.

 

 

I looked at the Makino PS95 today great machine and comes with the price tag.

[jeff]

If they start at $119k, then the prices jumped up significantly in the last couple of months.

I swear just back in November they started at about $80k. That price tag is the main reason we bought another Okuma.

460mm of TRAVEL on Z axis yes, the spindle stops about 6" from the table. Or 152mm for you metric lovers.

[DavidB]

I looked at a Hardinge Bridgport GX1000. Very surprised they have no orgars to remove the swarf from inside the machine. It relies on coolant to wash the swarf to the front of the machine, then into the chip conveyor.

I fill a 44 gallon drum with Alloy swarf in 1 hour I can't see this machine handling the swarf issue.

Crossed off the list.

 

I really like the Makino PS95 but its 60K more than a Doosan DNM 500
