A lathe is a machine that rotates a workpiece
and machines it with a cutting tool.
Cutting tools for external turning are called tool holders, while those for boring are called boring bars.
A CNC lathe can machine curved surfaces and complicated-shaped workpiece using numerical control and automatic tool changing (ATC) function.
A multi-task machining centre is a machine that can perform many kinds of machining operations. The machining operations that can be conducted include turning, milling, drilling an oblique hole, slotting and hobbing.
