or only a finishing pass on an individual
step segment if required.
The operator can also choose the
amount of stock per segment to be
removed. The stock removal is applied
radially (on the diameter) or axially for
features such as square shoulders.
The operator is guided through a
step-by-step process to create the
blank geometry and stock removal per
segment. Programming a blank from
scratch using BlankX only takes a few
minutes, drastically reducing setup time.
When applying different stock removal

Operators using the CPX Linear can
apply their desired grinding strategy to
produce perfect tool blanks in minutes
and keep wheel wear to a minimum.
