Changing a machining process that actually worked well,
to a Silent Tools engineered solution, saved the customer
185 hours of production time per year. The upper body
steering unit for a ship required a special dampened
milling adaptor to achieve a greater depth of cut and to
speed up the whole process. This face-milling operation
isolated, increased the productivity of the component by
162%!
