CBN & PCD TURNING INSERTS
Finished Surface (!m)a Improving Surface Finish Wiper
Under the same machining conditions as conventional breakers, but with the feed rate
increased, the surface finish of the workpiece can be improved.
a Improving Efficiency
High feed rates not only shorten machining times but also make it possible to combine
roughing and finishing operations.
a Increased Tool Life
When using to high feed conditions, the time required to cut one component is decreased,
thus more parts can be machined with each insert. In addition, the high feed rate prevents
rubbing, therefore, delaying the progression of wear and increasing the tool life of the insert.
a Improving Chip Control
Under high feed conditions, the chips generated become thicker and are more easily
broken, thus, chip control is improved.

NOTES FOR USE y Restriction for Holders
y No Restriction for Holders Use a holder with end cutting angle 93° for improving wiper
efficiency. A holder with end cutting angle 91° can improve
A standard holder can be used. wiper efficiency, however, there is no wiper efficiency with
