    Great to have you back, Adobe. And, that's a very nice looking enclosure as well!

    Best,

    A very good friend called me and asked me if I wanted a series 3 Bostomatic Mill that appeared in very good condition, but had been sitting in storage for 14 years, he said it looked good.(this has always been my "dream Machine ) Well ,I looked ( and bought this beautiful machine )..this machine has two spindles ne 200-7000 rpm and one that goes to 40,000 rpm ( gawd what do you machine at 40,000 rpm ? The table is immuculate.. nary a scratch, they ways ( what I could see) are like new and covered in Turcite, the way covers do not have any scratches,. no indication of use whatsoever..The machine came with 34 Bostomatic 40taper tools with collets, ( almost look like a CAT 40 )most looked brand new...

    Originally this machine was sold to the biggest Southern Arizona Aero Space Co to make prototype electronic boards..after finishing the job, the machine was sold to a high up employee, but they stripped the memory and damaged the control. The machine was shut down at 4460 hrs. There it sat for the last 14 years.

    As you can see it includes a very nice 4th axis, 2 huge cabnets ( one is actually air conditioned to cool componets ) . I will not use the cabnets in a retro-fit, but they have some neat componets if any one wants the cabnets (free)

    I'm transporting to my shop this week end, and will begin cleaning and retrofiting immediatley..will post as this goes along !

    Never as much time as I'd like, of course. But the mill is CNC'd and running well. Lately I've been spending most of my "shop" time on my G-Wizard Machinist's Calculator.

    Adobe,

    You could use that 40,000 rpm spindle and 4th Axis to make your wife a nice ring!

    Now that is a friend. You'd better have another kid so you can name it after that friend

    Good to have you back Adobe.

    Yeh, I'm sure she would appreciate a nice ring, but I'm more into Hot Rod Parts ( shiney stuff) than rings and baubbles...Also, I had to buy her some "gifts" when she found out I was dragging another machine home ( what do you need that for ?How much is this one costing ? What is your fasination with old machines? and on and on..)

    I was wondering if any one of the members have any experiance with Bostomatic 300 or 400 series machines ? The cat 40 tooling on the main spindle requires hydraulic Pressure to lock/unlock the tooling, but I did not see a pump in either cabinet ( it was getting dark, and the person we are buying the equipment from was in a hurry)The hydraulic lines were long enough to go to one of the cabinets ?

    My second question is the high speed spindle. There are lines going from and to the high speed spindle which are the liquid cooling lines.The one cabinet has what is labled as
    " Heat exchanger" and again I did not see any hook ups for the two liquid lines.

    Although there were 7 books that came with the machine , most had to do with motion control, but there are very few pictures . I will say this is one of the more complex machines with a two HP spindle I've ever seen.No doubt it would take an operator some time to learn the machine and the operating system. The section to calibrate and bring to .0001 ( that is expected) is 11 pages long !

    Again, if any members have experiance with this machine I do need help, so I won't break something or burn the thing down.

    Mark, glad to hear from you, how is the Plane Project ? Ours is going slow, slow ( watching paint dry ) And yes Bob is a very good friend, out of this deal he got a working CHNC (?) Hardinge lathe in very, very good condition. But no more babies for us ! We raised 9 ( a few adopted) children, and I would never want to change a dirty diaper again, ever.

    Every one, have a good and safe Thanksgiving !

    The Plane project is on the back burning, as we still don't have a house.

    In the meantime I built a Valve guitar amp and have been working on the controller to CNC the mill.

    Got the machine home and in the shop..There were some heart stopping moments with the last phase of getting the Bostomatic off the trailer..The 1st part was real smooth,my friend Bob rented the biggest forklifts I have ever seen, and it handled his lathe and my mill like nothing was being lifted.In fact, we could not get the fork lift at his house through his gate, so the boom was long enough to reach into his shop, with a 5000 lb machine on the forks..that is a 15 to 20 ft boom streatch ,with the machine in idle !

    Anyway the trip home was uneventful, then this weekend we borrowed a 5000 lb fork lift.
    We loaded the Fork lift on an Izuzu Truck with a flat bed and beaver tail, but required 5 ft ramps ...1st the fork lift broke one of the ramps going up, then slipped to one side of the flat bed, which almost tipped over the truck, the rear dullys on one side were off the ground and everything was just balanced enough to not turn over...we were able to get the fork lift over to the middle and lashed down. The 2-3 mile trip to our house was just as intresting, as the now top heavy truck wanted to sway a gut wrenching lot to both sides. At the house while transporting the Mill into the shop the rear wheels of the fork lift came up going over a small hump..Whew, any way all turned out OK. Now its up to me to figure all of the wiring out for the 4 axis.. will do pictures as this project progresses. Note, the machines table does not have one scratch or gouge..I'm going to put a 2 inch machine plate over the table, so I don't screw it up.

    Hi Adobe,

    What a nice find! I'm looking forward to the retrofit story, perhaps if it were less exciting than the trip home that would be a good thing?

    Regarding the HF spindle - would that happen to be a Precise unit, perhaps an SC77 or SC82? If it's an SC77, I have a copy of the operation manual I can scan for you if that's any use. I think the SC77 was used when Bostomatic was Boston Digital, perhaps 20+ years ago? They replaced the SC77 with the SC82, apparently.

    Kind regards,

    Jason

    Tree enclosure

    Can you post some pictures of the inside of your Tree enclosure? Does the mill sit in the coolant all the time? Is it tapered inside? I have a similar mill that I would like to make an enclosure for. As mine sits, it makes a mess with the coolant.

    Thanks

    Vince
