I upgraded to a Milltronics VMC instead... for the Lagun, I've just been replacing the belt as needed, it acts as a shock absorber for when I do dumb things with it occasionally.

I think you might be confusing clamp torque with rotary torque.

I know this is kind of an experiment, that's part of what makes it interesting. The newer Tsudakoma tables are direct drive like...

I've been considering this. The bearings in this motor are designed specifically to do this, although machining may or may not have been beyond the original design.

The motor specs are on page...

Not really possible. The motor IS the rotary table, so that would defeat the purpose entirely.

Thanks, though.

Thanks, I'll have a look. My control seems to have been upgraded to an SBC or otherwise is on the newer side of hardware revisions if that matters. If the chips are missing, I'm pretty comfortable...

I don't have a picture handy, but the motor is a Yokogawa DR1400A direct drive servo with a Litton Industries UR1A-400N drive. It's an older servo, I think surplus from its previous life in a...

My bad, actually... I looked it up, and the manufacturer claims +/- 30 arc seconds.

It doesn't have an encoder exactly, it has a resolver that feeds back to a position loop in the servo drive. ...

There is no belt drive and no gearing. This table is essentially a large high torque/low rpm direct drive servo with a mounting plate attached. It was originally shop made for a factory purpose -...

I do have AC drives. I'll review the parameter sheet for the ones I need to change - that's probably in the printed manual that came with the VMC. It's a direct drive 4th, so no gear ratio, or...

I do have it... I can see how I'd connect the wiring, but is there anything that has to be set in the control, like encoder counts, or to enable the axis?

Thanks!

I have a 4th axis with a servo drive available and I'm wondering if I can connect it to my VM16 with Centurion VI. There are two sets of axis connectors available in the electronics, although I...

Thanks for replying.

Yeah, I am running on single phase, although my understanding is that the VFD would just draw more current through the other two legs to handle it? If I'm getting reduced...

Hi, all;

I've been fully switching my workflow to use my VM16F after weaning myself off the knee mill I've had.

After learning the machine, I'm wondering what effect upgrading the spindle VFD...

Yes, thanks. I ordered some too.

I had thought I posted this yesterday, but apparently I didn't hit submit or something.


I'm cleaning out my VM16F which I acquired last year. I've finally gotten around to commissioning it -...

I forgot to reply back to this... I got the machine inside by removing the leveling feet, dismounting the Z servo, and using a newly purchased set of 3 machine skates. It went in with a couple...

Excellent, thanks. How tall is your door?

Hello -

I'm in the process of acquiring a VM16, and I'm planning on putting it in my heated garage.

It's barely going to fit in the door width wise, so it's going to be tricky to get in...

I've done that, and it's about a 40V/krpm motor. From that it's either an 80V (2k rpm) or 100V(2500 rpm) motor.

The diameter of it compared to e.g. Baldor DC servos would lead me to believe it's...

I have a couple of servos I'd like to use for something. The problem with them is that they're older DC servos and the nameplates are long gone - they've been repainted and/or cleaned away.

I can...

I got one from another CNCZone user a while back, but then I lost the file :\

The manual for the 310 that's out there is pretty similar... is there a specific question you have about the mill?

Roadside, I'm going to expand a bit on what Eldon suggested.

Because you're welding the metal (and machining it) to create your lathe, you're creating internal stresses in the metal. I'm assuming...

My image hosting is down. I'll check to see if I can find somewhere to put the images and restore them from a backup.

FYI, I'm currently getting ready to build another revision to my mill, a new...

Any updates on how it's working? Have you made any more mods?

I'm currently cleaning up an older version of the same lathe, and I'll probably CNC it before I'm done.

Do you have any issues...

Well, either way OP should check the specs on his ballscrews and rails to see what's recommended. If either can be used, usually there's a speed limit for the ball screws that's higher if oil...

Hi, just ran across your thread... nice build, way to stick with it.

A quick note: You mentioned a grease zerk on the ball nut. You should know that most ball nuts want oil, not grease, and the...

I've just acquired an X/Y table that was manufactured in the 1990s or early 2000s in Germany. Both axes are driven by DC servos and are designed for high accuracy and high rigidity in a vacuum...

I'll stick a reply here in case someone else wonders whether the encoder resolution change affected the operation of my mill.

In short, changing the resolution made the encoders work better in my...

Wow, nice work! I'd love to see some videos (or in RL) of your machine working.

I picked up a second mill myself... another 310. I haven't started anything with that one yet though :)

Erik

I ran across this thread today... since the subject came up, here's an idea of the size of machine needed to cut steel well using milling heads at a 4 foot by 8 foot scale.
