We also have 4053 and error 34 on the VAC3 drive of the subspindle.
Probably because the inertia of the subspindle is higher because of a bigger chuck.

Our secundary voltage is 210 volt. A higher...

Hi,

Sorry I can't help you. But we are looking at a second hand Jenn-wey JMY-6020.
Apart from the trouble you have with the machine, is your customer happy with
the accuracy and stability of...

Hello cgmaster,

Thanks for your reply. We were happy to buy a copy of a manual of the right building year of our local reseller.
Thanks

We bought a Kitamura mycenter 4 1990 with Fanuc 15 controll.
Unfortunately we did not have manuals with the machine.


We are looking for the Kitamura instruction manual of the controll and the...

We found out that it was not the encoder. It was the motor that was wrong.

We did have the VAC2 drive 5 volt repaired which showed 0 volt.
That fixed the problem
Thanks

We have 2 mill motors BL-MH201E-30T for a Okuma LR15M with live tooling
Both motors have exactly the same ohm resistance for all windings.
They seem to be good both.
However, the newer one did...

I will have the top PCB repaired in the next weeks and will report
what happened.

Thanks
Richard

If the Vac drive is not in the power loss mode then we
can start the machine normally and we get

1136 vac coil error a for both spindle 1 and 2

We already cleaned the white relais under the...

I have a machine with 2 Okuma VAC2 11 kw spindle drives 1993 Okuma LT15.
One of them gets a power loss red led while the green power led is on.
Only the red and the green led is on while all other...

Could anybody help me with a list of option parameters for an old Fanuc 15T

Thanks

Richard

A Fanuc specialist fixed the problem.
There was an inertia ratio parameter, in the manual
they said if you don't know the exact value make it zero.
Other Fortune lathes with Fanuc 15 controll also...

I have checked the bearings and couplings with a micrometer
and they seem to be fine. If I am pulling with about 300N
I only see 0.01 mm of deflection, it doesn't look like play.

I found...

Oke good idea thanks.
I try that next week.

Oke I see this is confusing.
It is only about the Z bal screw, I called this spindle.
It is not about the Spindle with the chuck, that is all fine.

Oke thanks for your suggestions
I already checked the spindle bearing, it has no backlash
in Z direction but the ballscrew nut has backlash,
about .04 mm. I have seen machines with 0.1 mm...

We just got a 1990 Puma 10S lathe with a Fanuc
15 controll. Overal state is good, it has about
9500 cutting hours and guides are fine.

The Motor of the Z-ax is a Fanuc 10S-2000 rpm
(same name...

We have a Takisawa TC3 and just bought a Victor
Vturn 20 with both a 1990 0TC. They both have the
same Fanuc 5.9 NM servo motor and the weight of the
turrets are comparable. There is no...

Hi Kudos,

This is really well done. We are evaluating to rebuild
a waterjet with EMC. Circular roundness is important
for us. Apart from mechanical clearance, every PID filter
has some...

Sorry for my bad english.

For example, cut only 0.1 mm and have
a feed of 0.03 mm/revolution/teeth if
you have a sharp mill. What I just mean
is to not cut for example 2 mm if this
is the...

The easiest thing to check is to up and
down the X for example 0.05 and -0.05 and measure if your total displacement is zero after this movement. If not, this is your backlash and
you can check the...

The Dialog has a direct measurement so
it cannot compensate for backlash and
it is not necessairy. This is a very precise
system usually and it will automatically
compenate for any backlash in...
