The
benefits of "CNC Qualified" broaches include
superior work-piece finish, perfect repeatability of
the sharpening process and a consistently accurate tool.
Increases in tool life are commonly found to be from
20% to over 300%. These improvements are the result of
the even loading of all cutting teeth throughout the
broach and strict adherence to the engineering specifications.
Near perfect tolerances are held utilizing pre-formed
plated borazon metal wheels along with high pressure
heavy oil coolants. This process produces consistent
tooth gullet forms without the heat and friction generated
by conventional grinding.

(CNC Regrind begins with probing the existing tooth
form into the memory of the machine which will then grind a minimal amount
of stock from the broach in order to return the tooth to its original
sharpened form)

*When "CNC Qualified" broaches
are sent to Pioneer for re-sharpening, we regrind the minimal
stock necessary to remove the worn cutting edges from all
the teeth and still retain the even loading per tooth. When
manually ground broaches are re-sharpened on the CNC grinders,
the broaches are first probed (to record in the computer's
memory the exact position of the face of each tooth ), and
then the minimum amount of stock is removed.
