FAQ's:

• 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.
