Basics of the CNC Mill

“Basics of the CNC Mill” explains the components and function of CNC mills. A CNC mill produces flat or curved surfaces on square or rectangular workpieces. CNC mills may have a vertical spindle or a horizontal spindle and either their table or cutting tool may move to execute a cutting operation. CNC mills use a variety of tools, which are kept in the toolchanger on a toolholder, to perform different cutting operations. The spindle grabs the toolholder and secures it. On the worktable, vises or fixtures may secure workpieces during machining. The CNC mill can perform multiple operations in the same setup. It is essential for a CNC mill operator to be familiar with machine basics prior to executing any cutting operation. A trained operator can use a CNC mill to create precise parts safely and consistently. After taking this class, users should be able to describe the general machine components of a CNC mill and their basic function.
