    I think that he meant the one for the 4th axis.

    My chum just took off today for a weeks vacation.

    Don't be afraid to look elsewhere if you are in a hurry.

    Default Victor 2050 Lathe?

    What's up Gentleman? Hope all of you are doing well. Ready for Christmas and all that Cheer.

    I'm going Saturday to look at an older dryed up Victor 2060 lathe local deal.
    Any if you Machine Dream Team fellas got any input or know about these machines?

    Still no mill here on my end..having chip withdrawal...had to build some small simple hydro manifolds on the ACRA BP copy just to remind myself how to read inches!!!
    I'm still shopping for a VMC...

    HOPE ALL IS WELL AND MERRY CHRISTMAS TO YOU ALL.

    Well.I own it now..$2500. its got a few things to maintenance and repair a leaky seal on spindle but other than dirty looks ok and sound's good so far..gear box oil is clean. Foot brake will be nice.
    Hope it will be a good upgrade from my 1996 china..
    Looking for a parts manual..like a free one! I found them online $60.00
    Anybody know where to get a free manual?

    That ain't no See and See.

    Should be labyrinth seals on the spindle. Not much you can really do to fix them. Unless it's leaking between the bearing retainer and the headstock casting.

    10-4 ewlsey....it wasn't leaking until I transported the machine. 82 mph for about an hour.
    Probably pressured up or more likely vacuumed it out .. may need nuthen'

    Check this machine out I just found give me some ideas what you guys think about this seems like a fair deal if it runs?

    My chum picked up a Lancer 1250 cheap b/c the spindle motor was out of it.

    That machine has an "integral" motor/spindle where it is all one. The mill had TSC and the union leaked a bit and of course no-one knew it, and the coolant got into then motor and destroyed it over time.

    The rewind on that is enough to scrap the whole machine!


    Now - I can't say if this one has that type spindle or not (possibly an RPM option thing?) but I wouldn't want in integral motor/spindle on a good day, but I wouldn't want an old one for sure!

    I'd want to find out if this is belt or direct drive, or integral.

    No one has ever given me a satisfactory reason why an integral spindle motor is good for anyone but the lazy machine builders. I'll take a few belts and extra brackets any day.

    I worked with an Okuma Captain with an integral spindle (that's a lathe). What a pain. No gear box, so no torque. I never saw the spindle bearings, but I can't see how it's any fun to change those.

    As Ox says, a rewind is going to involve the spindle bearings, probably the spindle balance, plus you have to get the fucker out of the machine.

    Good advice from you both..thank you. I'll ask or check it out online.

    I'm sure that price plays into it as well. Fewer part to make and assemble equals less $.

    Not sure about the linked machine. Since it has Siemens control it probably has a Siemens version of an integral motor and I've never worked on one. Fanuc integral motors can be re-wound without doing anything to the main spindle bearings. You just have to pull the cartridge/rotor assembly, then remove the stator and send it in for re-winding.

    In the case of coolant leaking on top of the integral motor the upper bearing would almost certainly be damaged and need to be replaced. Not too tough to do.

    May as well be looking elsewhere.

    These guys are really busy right now, and they can't find a spare 4th drive that they thought that they had, so they would have to buy one. Which would raise the price that much...

    Also - they have a nibble on the machine locally as a 3 axis machine only.


    If they don't sell it in the mean time, they may be able to dink with the 4th in a cpl of months if you still want it.

    Back in the day, if I remember correctly, Mazak was babbling some shit about "thermal stability",
    quicker accelerations, better surface finishes... BLAH BLAH BLAH.....

    Screw that, it takes a regular spindle replacement and turns it into a car loan.

    And that single speed NO TORQUE thing... Sucks... Running a drill on a 15hp Fadal at
    .012 a rev, move the same program over to the Mazak we had (FJV20, 12k rpm, 25HP, HUGELY EXPENSIVE
    integral spindle).. Had to back it down to .003 a rev to keep from stalling the damn thing.
    I stalled that thing ALL THE TIME...

    Odd thing, Fadal, lowly Fadal... The VMC15's, the lowest of the low of the Fadals.. They run
    single speed, one belt, no box, but they switch the windings that are used in the motor to get
    a high and a low..

    Would seem to be much LESS thermally stable with having the motor windings and the bearings all there together?


    That motor on that Fadal doesn't sound real cheap tho either?

    My Mori lathe has a 2 speed Yaskawa spindle motor. It's just a two winding motor and one winding has more poles for a lower speed. It's the same torque in either winding.

    You made me go look... Regular old motor, about $1500, 10hp continuous... But there is a
    board with 2 huge confusing relays and a metric buttload of connnections and it switches wye to delta or some
    confusing thing like that.. It flips from 2500 to 2501 rpms...

    Now I'm more confused than I was... I didn't realize that was possible.

    The winding with more poles will generate more torque (nearly double) but only run half as fast for any given input power frequency than the lower pole count winding.

    Yes. I mixed up power and torque. It develops the same power in each winding, but more torque with more poles.

    Jancolc, Ewlsey, OX, and Others... Hope all has been well with you guys.

    I need a test program written for a Mazak VTC20B. M32B I am going to go check it out and the seller doesn't know much about CNC..
    Like the buyer!

    I know You "Jancolc" got me interested in Mazaks and thought maybe you could shoot me a writ for spec-ing out this thing?
