Material Use

A wide variety of metallic and nonmetallic materials is feasible for milling machinery. Best results are obtained with materials having high general machinability ratings, see table below.

For most applications, castings, forgings, hot- and cold-rolled or drawn shapes, and extrusions of both ferrous and nonferrous material often have milling operations touch up critical tolerance areas.

 

Material	Ranking
