Horizontal machining center

nounStandard termMachine Shop

A CNC milling machine with a horizontal spindle axis.

A computer-numerical-controlled milling machine where the cutting tool approaches the work horizontally. This orientation relies on gravity to pull chips away from the cut, preventing recutting and tool breakage. They often feature pallet changers and rotary tables for high-volume production.
