Mills and Drills
Can anyone elaborate on the differences between a Drill and a Mill as
far as the relative size, placement, and materials when it comes to the chuck, spindle, quill, arbor, collet, bearings, gears, ect.? In other words, it's obvious that a mill can move the tooling along more than a single axis, unlike the drill press, but I am attempting to get a handle on the *physical* reasons why so many here say that a drill press shouldn't be adapted to mill use. If these physical reasons can be solved with only small manufacturing changes in drill presses to allow them to become more suited for milling, then does the conventional drill presses unsuitability have to do with the bottom line of the manufacturers or lack of consumer interest responsible for a lack suitable adapers/tooling, or perhaps there are other logistical issues involved? I've heard about the specific forces that the bearings and so forth would have to take as being a reason for a drill presses unsuitability for milling operations, but it seems to me that a suitable gearing adapter would negate much of these "lopsided" forces.(Probably at the expense of a lot of power). Also, I figure that since so many of you have been machining for so many years, is there a possibilty that any bad drill press milling experiences are at least in part a result of a lack of availability of suitable adapters and tooling for this? Anyway, in the meantime I will of course still take the advice of not using a drill press for milling purposes, but only when it comes to metals, because there shouldn't be as much of a problem with plastics like Nylon or Delrin.(But I'll listen to opinions either way). :-) Thanks a lot.
