Introduction to Hard Milling with Ceramics—Application
The cutting speed necessary for successful hard milling with ceramics is based on the actual material hardness, usually in the 45–65 Rockwell C hardness range At elevated temperatures the metal being machined becomes plasticized, or softened, which lessens the cutting forces, and aids in chip separationHard milling of injection mold cores, cavities and inserts is one of the best ways to shorten delivery dates and save money In fact, if you are not already hard milling, you will soon find yourself at a distinct competitive disadvantage Injection mold making is a perfect fit for hard milling, and this has permanently changed the mold makingHard Milling Is Not That Hard Moldmaking Resource
