CNC Swiss Style turning is unlike conventional turning
where the material is pushed through a guide bushing and the tools remain fixed
in a gang
tooling type setup. Where common turning centers can only manufacture
parts of a certain length due to deflection, Swiss Turning centers allow for
long parts to be manufactured with ease. Generally a length to diameter
ratio of 5 to 1 is ideal for Swiss machines, although shorter parts can be made
as well. A common misconception about Swiss machining is that they are
mainly used for high production runs. This is becoming more of a half
truth since new Swiss machines are outfitted with live tooling, turrets, and
even pickoff spindles which allows the machine to make the front of a new part
while the sub-spindle does back working simultaneously. This allows for
quick cycle times. Combine that with new technology setups are much easier
which makes short runs just as profitable as long runs.
