Introduction to Milling Tools and Their Application

operations. Facing is used for machining a large flat area, typically the top of the part in preparation for other milling operations. A face mill is a solid body that holds multiple carbide inserts that can be replaced as they wear out. The more inserts, the faster the metal removal rate. Cutters with a 45 lead angle are used most frequently.

Steam & Condensate System Improvements

in a Thunder Bay paper mill in 1967, which when combined with new open-mesh dryer fabrics in the 1970s, flooded the dryer pockets with low-pressure air, thereby lowering and leveling the humidity across the machine. These systems provided tremendous paybacks by increasing production rates and allowing higher sheet moisture levels.


dryer while the liquids are processed through a shared evapora-tion process. The evaporation process yields a high-protein syr-up, which is added to the animal feed, and an overhead stream of water for recycle in the plant. The high-protein animal feed product, being sold commercially, is an important product out of the biorefinery.
