What are you going to use to convert the acorn's step and direction signals into the dc servo drive signals?
As to moving the head.... You have to loosen the cross bolts, and tap the side with the nuts towards the head, and then, in theory, you can move the head. The head is very heavy and it tends to be a little stuck in place from dried coolant spray, misc debris, and (eh-hem) paint residue. Sometimes mine moves ok, and sometims I have to put a block of wood against it and beat on it with a 3lb machinist hammer.
Right now I'm planing on Viper drives with 160 volt Antec power supply,
Viper Servo Motor control products
I'm hoping when I put a lifting bar in I can break it all loose when I lift the head off base. I've had all the bolt loose and out to clean paint off, I'm going to re-clean them and powdercoat them before I reinstall them.
With it separated I should be able to move it on a trailer myself. My doors are 8 ft,so it barley fits through. I hope I can get a trailer in shop and lift it with a gantry crane.
A realy crane. Not an engine lift or most gantry cranes. I am sure you know, but the whole machine weighs about 4K lbs. Also, don't skimp on the trailer. A tandem trailer with atleast 6500 lb (7000+GVWR) weight limit is in my opinion the minimum to haul it. I brought mine home on a car hauler.
I will haul it over split in half. So gantry crane will lift it no problem. I just got a price to move it for $400 to just pick it up a drive it to new shop next door with fork lift.
Hey guys here are some videos on the steps I took to get this in paint,along with a final walkaround. Getting very close to move in date...I need to get my butt in gear!

Little update on the KMB1 build.
During a strange turn of events I no longer own the Hurco mill. Wife and I decided to build a new home and during the sale the new owner decided to purchase the Hurco from me. I was hesitant to sale it since it was ready for electronics,but did make it easier on me not needing to move it.
So consider this project closed
I ended up buying this mill from the new owner at the end of January. It was the exact type of project I was looking for. We picked it up and moved it a few days ago. That thing is heavy. The loader we brought wouldn't pick it up so we had to run down to the rental place a few miles away and rent an small boom lift. Its sitting on a trailer in my parents barn for now until I can line up a way to pick it up off the trailer and set it in my shop.
I plan on continuing the retrofit using an Centroid Acorn board. They have a lot of neat features including that 4th axis control.
Were there any spare parts that you left, or was it just the mill and the operator panel/station? More or less I'm looking for the way lube system and the power electronics. I would rather reuse some of the old fuse holders and power supply components instead of designing my own circuit boards from scratch.
Thanks for your time.
Hey moore60
Sorry for late reply,I didn't get a notification.
What a small world it is. Unfortunately as I reach the deadline on moving out I had actually planed on scraping it and the new owner said he would get rid of it for me. I tossed everything else in the dumpster including the full enclosure I made for it.
All the way / ball screw oil lines are still in place. Input line is on the left side of the knee as your facing it. The one line feeds everything.
Hope you you get it going
Good Luck
Oh? Wow! I'm so sorry to hear that you had to let the machine go.
I had at one time about decided to scrap mine out and started selling off tool holders. Then I changed my mind and fixed it. Now I miss all those tool holders. On a positive note I discovered I really like Acura Flex tool holders, and brand new collets for them from Universal are not very expensive.
Just picked up a Hurco KMB-IS at an auction.
Intention is to replace the early 80's electronics with something considerably more modern.
I have the owners manual and the operators manuals. I believe this unit is serial number 4 or 5.
Assuming the quill is Kwik Switch 200, but I can find no mention of this in the manuals. Machine did not include any tooling.
Can anybody comment on the availability of Kwik Switch 200 tooling? If the situation is bad enough, the Hurco might turn into 3500 lbs of scrap iron :-(.
Machine has Electro-Craft MAX-430 drives and 0703-02-089 motors. Power electronics (electrolytic capacitors) don't age well. Probably scrap the drives. Would like to use the motors. Can find no spec sheet on the motors. Does anybody know where I can fine one? And what's the advice on encoder upgrade and new drives?
If this project takes off, I'll probably start my own build thread.
