Advice

[Rakesh]

Goodmorning everybody,

Our company is thinking to buy Hardinge Lathe,Quest 6/42 and Quest 10/65 with subspindle and Y axis.

Do anybody work on these machines and how is their performance compare to Miyano, Mazak and Nakamura with the same options.

Any input will be helpful.

thanks

advice......don't use black text

 

sorry, can't help with your lathe question

[crazy^millman]

Well the black letters are funny. Well I consider the 2 a big cut above then Hardige, I would take the Mazak just becuase I know the machines. I do know the Nakamura is a very nice machine and I think they are running the Fanuc control which is very good IMHO.

 

HTH

Sorry John if color bother you but I put the red text and it appear on my screen as the red colour

[John13]

It doesn't bother me, I just can't see it without dragging the mouse over it to highlight it.

We already have 2 hardinge swiss type machine which they now stop making. This was their low end machine(swiss type) and they claim Quest type is their high end machine. But I still want if any body work on the quest with Y axis.

I have [2] Conquest 'Super Precision' lathes and I think that they suck. I also think that Hardinge, in general, is lousy to deal with and that their customer service is, essentially, nonexistent.

 

I think Okuma makes the finest lathes to be had, but I'll take a Nakamura or Mori all day every day over a Hardinge.

I know they seem to have alot of service issues, hold great tolerance but dont run often. Mazak, Nakamura, Okuma!

[Rakesh]

Chris, you scared me now. I also know their service is bad specially in canada. With Chris comments I have to think more to buy these machines now and I appreciate if more input come regarding the Hardinge machines.

thanks

We have a crapload of Hardinge lathes. We have one Questsp with Y and Sub and its been a great machine. No service calls have been needed and these things can take a hit. We've had it since 2002. 8000rpm live tools are nice to.

[Guest CNC Apps Guy 1]

I'd have if I was choosing, I'd pick wither the Miyano or the Nakamura. I love them Fanuc controls. ANd whoever is writing your post will also.

[Rakesh]

Hi Tryon, Good to hear that.

Do you use mastercam to program y axis?

From where I can find the tutorial for Y axis and sub spindle programming?

Any input will be appreciated.

thanks

[Rakesh]

James, Hardinge is also with the fanuc control

[tryon]

Yep i have my post all set with this machine. I think some sample Mill/turn parts are in the sample folder with the install. You can also read at the top of a 4 axis lathe post and it describes the proper T-planes and such that is needed to get the toolpath to work out properly.

[Rakesh]

Hi Tryon

I never work on editing the post and always get it done from the dealer.

If possible, can you e-mail me few samples with the NC output. I just curious what plane gonna be when we using cross milling cutter and front milling tools and how to select those plane.

thanks

[Guest CNC Apps Guy 1]

Prolly gonna have some issues with service from what I hear on Hardinges.

[Rakesh]

Hi James,

You are right, service was bad specially in toronto area but now they have 2 service personnel and 1 service guy for toronto area.

One more thing I am worry about is how strong is milling side is? These machines have VDI30 holders and ER25 collet system. This look to me little weaker. I guess Tyon can answer better about its stength in milling end.

thanks

Miyano gets my vote. Ours gets serviced just about as often as a mori, which is never

No milling on our miyano though, so can't comment on that.

Lucky for you since their service is awful

You could tap the turret on my T51SP with a plastic hammer and knock it out of alignment; I have never come across a more finicky or gutless machine in my life. A chip that would pull a 60% spindle load on on of my Okumas will break the needle off the loadmeter on the Conquest before it fills the screen with red as it alarms out...

 

If you want to see how well ours 'take a hit' there are photos on the FTP of my machine 1/2 apart after one of my guys did a little computation error. Here's the old thread:

 

Hardinge thump and bump thread

 

VDI, especially VDI30, is going to be a weak link in anybody's machine, but you need to be realistic about what you're doing. If you are profile milling aluminum of plastics or something you will probably not tax that machine too much; if you are going to be working with tough stuff I would want to see a demo or do a turn-key regardless of whose machine you look at.

mori is the way to go

[Rakesh]

Finally we bought two Nakumura WT-150 with LNS bar feed. I hope coming week we will start cutting the part. This lathe with double spindle,two turrett,y axis on the main. Any advice from the people who using the mastercam for programming these or similar machines and Any advice for handling these lathes will be helpful?

[Zoober]

Miyano hands down. But then you knew I'd say that!

[Rakesh]

Hi everybody,

Where I can find the sample files for mastercam using twin turret, twin chuck,live tooling, y axis, and showing part tranfer.

Thanks

[terry5357]

programmed in screw machine shop had 5 citzen L13's and 6 L25's and one conquest which sub spindle would just quit in middle of pick off........what a piece of (*(*&%&^%%^

[Rakesh]

Terry, I guess you are talking about Hardinge machines but we bought now the Nakamura lathes.

Even hardinge, we have 2 swisstype and we don't have any problem

thanks
