Boxford 165 HMC

Chris, I have the table and a double bracket with small Vice for the machine, but first I have dismantled all, to see if the guides are ok, how is all build and so on. I will try to remove the ratchet from the rotating axe and add a small bicycle brake so I can move not only in 45° steps. Maybe later, I will add a 5th axe and can machine parts nearly complete. If I add some
highgrade connectors, then I can change different slides, because the parts are not really heavy.

Unfortunately, I don't have any documents for the machine, I asked Boxford before but they write, the machine is to old and really rare, so they haven't any documents, parts or anything else. I write to the school, from where the machine is, but got no answer til now. What number has your machine, mine is 4209, where I think 420 is the series and 9 is the machine number.

I can explain the 3 small relay under the big Relay (which is actuated, when you press the green button on the right sife of the cabinet and released with e-Stop at the buttontable and the red bar under the machine)

The first is actuated, when the front doors are closed, if the doors are opened, no move, whether axis nor spindle is possible.

the second starts and stops the spindle motor via the lenze driver.

the third, next to the big one, changes the direction of the spindle. 2=CW 2+3=CCW

But I haven't any clue what is the function of the single white relay, (your Pic3 below Lenze driver) I suppose, it's for the tool turret, that is only a geared DC-Motor who turns the tooldisc 1/8 turn and stops, when the switch came to the hole on the underside of the disc.

I've got a wiring diagram for the 190 VMC from another colleage from here, that I can send you, but thats not complete, because this machines have only 3axis instead 4. The only difference is a different Stepper drive ST-Electronic DS-200 integrated package, and only one fast serial Board for connection to the drivers. All others seem the same.

Uli12us, my machine 4208! Wow,
but I wish I had the nice wiring that is in your pictures, I have managed to see where the feed to the relays comes from I can see that in your pics.
Can you please take me a picture of the RL1 from above so I can see if there is wiring missing from the relay base, if you can send me the 3 axis drawings that would be great, I wonder if I should put a Fuji frenic or similar drive in because that would save the need for some of this wiring especially the spindle reverse!

Can you identify the wire that my screwdriver is pointing to or more important is where it goes to?
i want to fit homing switches on x,y&z and a probe to set tool lengths but I am a long way from that yet, eventually I will be engraving the odd clock face and milling some fancy little clock parts on this baby!
i took the tool turret off the machine for somewhere to put my laptop!!

thanks for your help,
chris w.

I have some big trays for the machine to put the computer, Monitor, Keyboard and from 1995
maybe a big box of Diskettes on it, anyway, I want the toolcarousel and hope I can upgrade it to a 2nd disc, eventually if to room is sufficient, I'll try to add a ATC for it. Can it help, if you have the manual for the Lenze driver, I must see, if I have it in english instead german as well.

I have kept the disc with the tapers and numbers on it so I can identify the tools but my thoughts were if it's not an ATC then it's pointless!
i could use the google interpret web page for translation.
and I can look at the pictures.
thanks.

The screwdriver should be the hot wire from mains Plug, the next is the neutral wire, but I don't know, how its made, that the hot wire comes always to the hot wire plug, we in Germany have a mains plug, that can entry in 2 positions, I don't know if in Britain the hot wire must be always in the same position. Long time ago, i have a neighbor from britain, he had a radio or something that won't work, i had just turned the plug and it runs.
the next 2 wires goes to the motor, the last 2 unconnected are for a Motor with solenoid instead a permanent magnet.

With tools, they have all nearly the same length ok, but if you have tools with different lengths, the toolturret is much safer
