440 cabinet complaints

Mill

Anyone modify the cabinet to make the area around the machine cleaner? I seem to get as many chips outside and behind the cabinet as I do inside it .

Yes: In progress and “beta”. I cut and bent some sheet metal to close off where coolant/chips try to escape under the rear wall and out the rear corners of the chip tray.

My bigger issue is the coolant dripping off the doors which swing out, instead of sliding back into the cabinet. I found a couple of examples of completed sliding door conversion…

I totally agree, I have had little trouble with the cabinet but for the awful doors. I wish I had known. I really would have made different choices. When I do small parts and loading/unloading the coolant just pours out on the floor as they drip (steam) off the doors.

I dont have a 440 but could you somehow put a bead of silicon along the inside botttom of the door to keep the coolant from gathering there? Or even mill a channel so it would all run back to the hinge.

  1. The doors open outwards. Coolant and/or chips will end up on the floor under where the doors open
  2. The bottom hinges of the doors, depending on what your options are, may need to be shimmed to angle/position the bottom edge where more coolant spray on the doors that dribbles down the plexiglass will end up back in the enclosure instead of outside - https://www.youtube.com/watch?v=XPQzmR6lX7U&t=3s
  3. I tried some silicone edge guard that I saw suggested. Didn’t stick/last and was a pain to position.

A sliding door conversion would really the best solution for those who are using a 440 with coolant and would be the design of choice.

I used an aluminum “U” profile extrusion at the bottom so the coolant runs down from the “window-doors” since they open they still make a puddle on the floor. I am often doing circular interpolation on round , stepped bushings which is quick (relatively) and the doors are open to remove and replace work. Very very messy. A sliding door which stays inside the cabinet would be a big improvement. I would prefer a 1500MX.
