While waiting for help with a programing manual for the "out of style Analim Crusader II Lathe I bought I decided to make a chuck adapter for a 4" three jaw to one of my TG75 holder's I have a part I make for one of my customer
that I'm trying to produce with a minuim of hand's on time. I have done everthing up to this point in the mill except facing the one end and face and turn the first .800" in the Lathe manualy I Drill the large hole chanfer and thread in the mill Then I turn end for end and Drill and tap the other end and hog off the excess material on the od then comes the lathe part see pic's I hope Note ICRD in the third pic" Inprovised coolant regulating device " The finished part is on the right Took some playing with tool's and speed and feed to be satsafied with the part the only critical OD is the very bottom last .750" I hope to make the next batch on the Lathe but I will still do the internal thread in the mill It's slow but it is a weard metric thread and I have a proven program for the inside of the part P.S. any one with any pointer's on the lathe Emale at ktaylor253@earthlink.net Also need to finish the encloser lathe throws the birdnest all over!!!

Have finally gotten back to the retro of the BTC I bought a few months back, and wanted to get a sanity check on something:

Are the original servos (Powertron from Contraves) 100VDC??? This seems outlandishly large... I am going to build a supply for this, but at 100VDC and 15 amps apiece I wanted to be sure before committing to that size components.

Any info is appreciated!

That is about right, I am still using my original power supply, and it is at lest 80 volts.

Hello to the Btc Club,
I'm in the Pittsburgh, Pa. area. My btc was completely operational when demonstrated before I purchased it. I'll complete a rotary phase converter this week, then find out how well it survived the 10 mile trip to my shop. Any pointers on what to check before initial power up, or what sequence to follow when powering up?? Although I received 26 tool holders with it, there are no collets in the collet holders, does anyone know what type they are?? I will have a lot more questions shortly. Any other thoughts on getting the most from this machine??

The most inportante thing is Voltage If you have a service manual it has the places to check double check everthing if not I can foward a page to you The tool holder's small ones with extened length take DA300 the stanard large ones are TG75 There are suposed to be some TG100's out there I haven't put my hand's on any yet the tap hiolders I will have to check the # of there are large and small make shure the iner part of them moves in and out freeely or you will break tap's I have a tooling manual with part#'s post some pic's of holder's and I can identify I should have some extra collet's for the TG's and maybe some tap collet's will sell swap or whatever you must have air hooked up and fill the air oiler with marvelmistry oil and turn up the oil for a while to lube the selonid's there pron to sticking you can use a pick and manualy accuate the valves to free them up also fill the glas bowel on the tool changer cylinder if it is empty the changer becomes a treblejay fil the way lube res. or it won't move or come out of setup keep us posted Kevin

i Just had mine delivered yesterday, MY GOD THIS THING IS HUGE. at least it is in a 2 car garage.i'll try to get some pics up by tommarrow. it needs a little TLC and i still ned to get a converter. any sugguestions?? the tag on the mach says 320 3 phase on it.

the machine came with all of the manuals, i was thinking of scanning them and makeing a .pdf so everybody can have them

[Kevin Taylor]

Are you shure 320 how about 230V 3phase hope it's a typo Need a tall garage for them good luck Kevin

Thanks for the info Kevin. I have the installation manual with the page you refered to in your message. I don't have a tooling manual, but none of the holders appear to be tap holders. I could use a tooling manual and the first two sections of the maintenance manual, any sources?

Have a great day,
Chip

i have all of the manuals, they came with the machine. let me know what pages you need and i can scan them for you.

it was a typo its 230 3 phase, any one have an idea on what kind of phase converter to get???

also here are some pics, i know alot of the sheilding is missing, i took it off for the move so it wouldent blow away down the road

I have been using DES-CO 10hp rotary phase converter on my BTC-1 with great success. They can be purchased on ebay for $545.00 www.deselectric.com The BTC has a 3hp spindle motor so you may be able to get by on a 5hp rotory converter, However that would be all you could feasibly run from it. I chose a 10hp with the intent of having a small amount of added 3ph capacity. Originally I purchased it with the electrical box attached to the motor...This was a mistake. The vibration caused trouble with the components. Des-CO sent me a NEW mount on wall unit at NO charge and I have not had any trouble since.
Heed Kevins advise on checking your incoming power and when wired in your output from your rotary phase converter BEFORE powering up the BTC-1
These machines run on the SMOKE theory... If you let it OUT they quite working!
Happy Milling, Stephen

do i have to use a rotary phase converter??? what about any of the other styles?
the reason i ask is i have access to an electronic one for free.

[machintek]

Define "electronic." There are such converters called "static." They are worthless.
A good digital phase converter goes for a minimum of 5000 dollars. But they work very well. Good enough to run high end machines with fanuc controls.
