Re: [CAD_CAM_EDM_DRO] Mini Toolchanger Videos

I noticed that in most of those videos the tool changer was mounted on a
Sherline mill. I tried for a while to use a Sherline for production work,
but found that the amount of maintenance required to keep it running
outweighed the benefit of using it that way. I know some people use these
machines for production work, but I think it only works well if you have the
right combination of precision, complexity and price insensitivity. In other
words, if you are producing something that commands a fairly high price but
does not require a great deal of precision and does not have to be produced
in large numbers (i.e. cost-insensitive niche market) then it might work.
Otherwise, because these machines were never designed for continuous
operation, the cost of maintenance and rework becomes prohibitive. Unless
somebody is a wealthy CNC hobbyist who loves gadgets, or one of those few
manufacturers who fit the profile, they would be unlikely to have any use
for such a thing. Personally I think they're pretty slick, but would view it
as a time sink unlikely to pay off in any way besides fun. If that's what
you want, go for it.
