Denford Micromill rebuild
Posted: Sat 02 Jun , 2018 12:01 pm
I'm updating the internal components of my Denford Micromill and thought it may be useful for anyone considering doing the same, plus I would very much like some help as I've not done anything like this before.
The machine was used in a school to cut mostly acrylics so has had very light use. I'll be using it to make small injection mould tool inserts from aluminium. This is the plate: And this is what it looked like before: I stripped out the parts I wasn't keeping and changed the transformer to DIN rail mounted power supplies. For now I'll keep the spindle motor control board to get me up and running, but I'll be replacing this and the motor to a faster one later, as soon as I get some advice on what to buy. It now looks like this: All high voltage wiring is complete and safe (I blew the house fuse on the first test because of a short!) so I'll now work on where and how I'm going to mount the motion controller and stepper controller, and how I connect these to the E-Stop, guard lock, key, fan (new), work light, power light and everything else. The basic wiring is quite logical, but everything listed above is way over my head and I'm hoping I can get some help here.
Thanks, Steve
