[K&T EB]

I am restoring a Kearny and Trecker Milwaukee-Matic Series Eb. It is a small horizontal cnc mill with an indexing tombstone and a tool change. Is anyone out there familar with this machine? I am looking for any documention or pictures anyone might have? Specificly I would like functional descritpions or maintanence manuals for some or all of the systems. I have exploded drawings, which are pretty helpfull, but I am still lost on how the spindle gear change and tool change work.

Thanks
Jeremy

Giddings & Lewis bought K&T. They should have any info you need. They're located in Fon du Lac WI

Very cool. We are in the long proccess of converting a IIIb. (I am not up on my k&t models....)

I have a thread here..

(1 of too many hobbies... but we just scored some rather large servo amps and I might be off the hook for making them)

Do you have any picutures? The k&t are really well made. The one we have uses recirculating kneedle bearings for the ways.

Sam,
Here are some pics of the mill, it is smaller than the one you have. This machine was origanaly hydraulic and was updated to CNC by kearny and Trecker around 1980. I would have liked to use the orginal electronics but I was missing to much and decided to go all new (newer anyway, most the parts are used off ebay).

As I take the machine apart I can't beleive the quality, it is as heavy duty as machines 10 times its size.

I am having a hard time finding info this machine, do you have a resource for manuals or anything?

[samco]

wow - that looks like a mini-me version of ours. Very nice! I would love to have one in the corner of my garage...

I don't have any sources of onfo on them. I think it is very different from ours. Shift logic on ours is 4 shift rails + 2 ranges in hydraulics. (we got rid of the hydraulics motor and put in a vfd)

So there are 4 shift rails giving 16 gears.

If you went with emc2 and maybe mesa or pico hardware - you might be able to directly interface with those servo amps... (if they take industry standard +/-10v or pwm+dir... What are they? (plus you could rigid tap... )

oh - your are the one going camsoft.... Darn

I have a camsoft PC control and the spindle is on a VFD, If I put an enconder on the spindle I should be able to use digital gearing to rigid tap.

You're lucky to have the eb instead of the infamous K&T180. The eb was a solid machine. With a modern control should work wonders.

I seem to recall that one of the first EMC conversions was a K&T 600.

[samco]

Do you have the tool changer?

sam

[K&T EB]

I do have the tool changer, my ceiling is a little low, the tool change itself will fit but I need to cut a hole to put any tools in it.

Sam,
Why you do you say "darn" on Camsoft?

[samco]

Sam,
Why you do you say "darn" on Camsoft?

Oh - I am just biased. (I love emc2) (I consider it the swiss army knife of machine control) 'opinions are like a$$holes.....'

So far I don't love camsoft, can you give me a bit of info on EMC, I see its free, will it run a full cnc with a tool change and lots of I/O?

[samco]

I am assuming it is using the galil hardware? galil is a motion card - emc has no use for that. So that might color things if you have already spent the money.

Emc supports a ton of I/O. The mesa pci card has 72 i/o and emc allows you to use more than one. Take a look at the supported hardware.

Pico hardware is also popular.

Looks like I'm stuck

Hello.
I have a K&T-Eb from 1969.
Equipped with the option 60-tool magazine. (similar as samco's magazine.)
Machine is for sale and have full documentation.

this is jthellin, how much asking price? and are the books with it? cell is 1 713 992 3914 i used ti run these machines in the early sixties

Too bad I have not looked at this. I came across your questions from a different search. I retrofitted 2 of these with Fanuc 0M controls. I did it a long time ago, but still remember some of the details and have a few parts. I converted the indexing table to a full fourth and changed the motors from hydraulic to ac servo. The spindle was changed to AC vector as well. It made a pretty good machine. I wish I had seen this in a timely manner. You are probably finished by a long time.
