Ball nose milling cutter CBN-FB2

CBNfor steelfinishing

Product Overview
Mold materials have grown increasingly harder in recent years, demanding higher machining precision. The CBN-FB2 uses a CBN sintered body with superior wear and heat resistance to maintain consistent cutting geometry over extended runs. This stability reduces dimensional variation caused by tool replacement and shortens overall mold manufacturing lead time by limiting machine downtime.

Product Type
