Sure. I'll measure them tomorrow when I'm in the shop.

Hello Thomas,
I did purchase from UK a used Mazak VQC 15/40 manufactured in 1989 with M32 NC, no pallet changer.
I did disassembly it and clean each part because it was a mess, very close to your pictures. Did not paint it yet, only purchased the polyurethane paint and I did not install the protections on it because I decided to start it after the cleaning processes.
I have the same Mazak machine with a small difference, I got the version with AC servo that use MR-S amplifiers and 5000PPR encoders on both motors and ball screws.
Unfortunately the axis amplifiers cannot be used with analog input, they only connect to FC335M using bus link .
Both motor encoders and ball screw encoders are connected to the amplifier. Amplifiers close the loop with add on card RF31C.
After starting up the machine I had problems with the initialization procedure because the NEC floppy unit was not functional. I was able to replicate the System disk and DNC Option disk using Omniflop and create some USB images. I also did purchase a FLOPPY emulator at this phase.
The intention was to test first the machine and to see how M32 looks. I was reluctant and scared of servos replacing idea.
Reinitialize the M32 controller and again got an error (different from the first one), the second is a parity error message and a CPU_B DOWN error. I did purchase MC111, MC121, MC427 etc from eBay and start again. The same error, Parity Error , Error at or near $00780DCA
CPU_B DOWN.
At this point I decided to contact Mazak representative in my country, register the machine and got no response until today (one month waist).
So my next step would be to remove the NC controller.
I have two option to use MR-J2S-70A with HCUSF73 servos (I have them already from a future project of a rotational axis) or use a generic amplifier Argon (ordered already from granitedevices) from www.garnitedevices.com with the HA83 servos.
Until now we did use Linuxcnc on our CNC machines so we are familiar with Axis interface. We did had some problems with Mesa regarding grounding in the past because of poor grounding points.
How is your experience with Kflop/Kanalog/KConect until now? It was easy to program the tool magazine?
Thank you,
Razvan
Hey Razvan,
Seems like you have a lot going on. Overall the kflop is pretty good with only a few issues. I do on occasion have the konnects fault out and need to be reinitialized but that is due to a bad cable connector and that only happens about once a month. Also on rare occasions, while running g-code and a custom user program is encountered, like during an m code or S word, the program will hang for several seconds and then continues as normal.
Something you should take into account is that the controller can only perform coordinated motion with 2nd order motion. This makes the jerk infinite and produces a harsh thump when an axis is accelerating if the acceleration isn't set quite low. For a machine the size of the VQC the acceleration has to be set quite low because of the inertia otherwise you will induce a lot of stress on the screws and bearings.
Other than those issues the kflop and it's peripherals are great. It's easy to customize and program, especially if you're familiar to C programming. If not it's still pretty easy because there are a ton of sample programs included with the software which can easily be customized to suit your needs.
The tool changer was very easy to program. The machine I have uses the hydraulic motor which spins the carousel via a geneva cam. Some of the newer VQCs used servo motors which made indexing the carousel to a non-sequential tool much faster. This would require you to interface to its servo amplifier just like any other axis but should still be pretty straight forward.

Hello Thomas
My machine had MR-S AC servos instead of brushed DC servo that you have. MR-S AC servo does not have analog controls, driver can be interfaced only with Meldas NC Controller.
I did replace the MR-S servo pack with MR-J2S , 750W ac servo pack. The HC-USF73 had the same flange so no modification was necessary. Only new pulleys because older had taper shaft.
I did install LinuxCNC and Mesa 7I77 board and 7I85S for extra encoders .
How did you setup the limits, the machine has a trapezoidal limit dog.
Can you tell me what type are the oil sensors? The spindle chiller is a pressure sensor or temperature sensor ? The hydraulic pump for the ATC motor is a pressure sensor?
What encoder input signal did you use as feedback device for Kflop? Did you split the spindle encoder to Kflop and FR-S driver?
I do not have the electrical wiring of the machine so I only have to go on each wire. Can you share the wiring diagram, l will pay for it. Will help a lot, because finding each wire will eat my time.
Thank you,
Razvan
Thomas I send you a PM with few questions...
Hi!
I really appreciate what you've got with this machine!
It was nice and it works well as usual.
I have a question for you.
I would like to buy such a machine. The seller wrote that ( Maschine hat Fehlercode 55X Servo... , Machine has error code 55X servo ) this error message is.
What is this, what's wrong with the machine?
Thank you very much for your response.
Sincerely Yours Mihály
Hello
Can you email me? i got a VQC like this from 1990 - i got some servo drive problems maybe you can help me with :)
my email is vohnsen AT gmail.com
pl share images of whole mazak vqc 15/40 parts during retrofitting and pl share mechanical manual of mazak vqc 15/40 if available and send it to "[email protected]"
Hi Dear Thomas,please give me email,i have question from this machine,need help
