Been lurking for a bit, reading the various threads about Makino KE-55 and RMC-55... Finally got one, an RMC55 from 1990 and thought I'd start this thread as a place to share notes on these machines, and for me to log my adventures with the RMC55.
I was really hoping to get a newer KE55, as I'm...
Have you checked the "crash sensor" at the back of the head, right by the spindle motor belt tension adjustment? It's labeled "ESP Z" on mine.
These have a unique feature that allows the head to move up in a crash, tripping that switch and putting the machine in an e-stop state.
Thanks,
Alex.
This machine appears to be at/from Systron-Donner in Concord, Ca. That facility has been around for a long time and the machine is probably in nice shape for it's age. Now, as far as the great deal on shipping, I don't know hahaha.
They did gyroscope guidance stuff and electric test equipment...

This has a field control with a fair number of parameters to tweak it's behavior. And I do have the manual of the drive.
Here's a video of some gear shifting:

Thanks for all the input on this..... I am still thinking about strategy and, honestly, mostly ignoring it. Another power up and test session is tempting....
David Erickson may be interested in buying it, and stop by to take a look. In the meantime I I'll try to it up again see what it does...
I have an almost identical looking FP-3, that I've had for a long time but only recently started using/cleaning up. Drained the old oil and flushing with AW-32 hydraulic oil now.
I'm thinking of a set of bellows and way wipers as well, would be curious to see what it takes to get that stuff...
>> So even without a 50 HP, there'd still be about 100% or better reserve.
Here's the data plate of the drive. Obviously it's current and voltage limited in the parameters to match the motor specs but it does has a wide operating range :-)

>> I need to work that I/M gearbox, rebuilt 10EE headstock, NOS compound, etc., into this deal somehow...
Hmmm... don't tempt me lol.

>> Alex — are you selling both your 13EE’s or just one?
Just this one. The other one is a little newer, has the tube drive, but is dirtier/more beat up/needs more work to run. I'm thinking of doing a complete restoration on that one someday.

Yep, I did... And sending him an E-mail did not result in a reply. No phone number in the ad...
Are we all in agreement that 13EE is MG and 1000EE is a Tube machine? And MG is early 50's and tube late 50's? I'm still trying to figure it out after 20 years of obsessive collecting and having had...
The new drive is a 4-Quardant SCR Line-regen drive. Decelerating is done by returning power into the grid. The 13EE has a shunt wound motor, and reversing rotation direction of the motor only needs the reversal of the armature voltage. When decelerating (torque reversal), voltage is the "normal...
Thinking of selling one of the two Mythical Beasts (lol) from our collection....
1953 Monarch 13EE 15.5" x 54" toolroom lathe. 25 - 2000 RPM in 4 gear ranges, shifted electrically. Rapids in Z and X.
Had a Ward-Leonard (Motor Generator) drive originally, but we swapped in a Baldor SCR...
