Why does high speed and hard machining of molds and dies require tooling that can take the “heat” of higher surface speeds?
-
Answer: Efficient high speed machining generates high surface heat that must be dissipated quickly to ensure long tool life.
What role do coatings play in heat reduction?
-
Answer: Many different variations of these coating are available, such as TiAIN and Si (silicon).
Why is tooling geometry important in controlling heat?
-
Answer: The tool geometry allows for efficient chip removal, which removes the heat at the same time. Millstar’s new geometry is evident in the MB ball nose insert.
