The stamp battery must be regarded from two different points of view, (a) as a crushing machine, (b) as an amalgamating machine, and it should be remembered that the modifications designed to make it a more efficient crusher often reduce its power as an amalgamator, and vice versa.. Stamps were originally designed as crushing machines, and the tendency is just now towards a return to this view ...
A thread mill is a specialty tool designed to cut threads via the milling process.
