Hello everyone, whoever the hell I may be (lol), I need help for my friend Ed,
he runs his own low-tech metal shop of machining and welding services and
does not have internet, he gave me a really low price on a minor peice of work
so I offered my help in asking in here, about his problem.
Recently he bought the upright mill, Gorton Mastermil 1-22 and it is HUGE!
Purple accented! He got it from Raytheon and it has a makeshift electric
control box that needs repair, he can get that done but a source for parts would
be nice to know about.Need a new reverse control switch, and the electrical
innards re-assembled. Large motor on top runs fine but needs "genuine" 3-phase
hook-up, to put it mildly, not a real problem.
Important stuff:
What he needs to know is about the collets and collet holding system in detail,
he want to switch from whatever it is to R8, like his smaller (large) mill-drill
uses, Does anyone know anything about it? Can the collet holding system be
replaced with currently available or commonly available used parts?
Current tool holding collet shape, circular:
_______
/ \ top camfor/bevel (camfer?)
| | here approx. OD is 1 3/4" or so, maybe less
| |
-------------------
| | | | approx. OD is 2 1/2" with two opposing 1/3"
cutouts, 1/4" deep, both sides
------------------- and approx 3/8" thick, sticks-out maybe 3/8" as a rim all
around
\ / no straight here, cone top flush to the middle
section
\ /
\ cone /
\ /
\ /
| |
| | straight, approx 5/8" OD and approx. 5/8" long down from the
cone
-------
through-hole top to bottom
These tool holders are/were sold by Enco and made in Poland, but the box
does not say what type of collet it is. He would need a new collet holding
system for the head.
Please help, thanks very much,
Alex
