Turret
Unlike machining centers, CNC lathe do not have a magazine that can hold dozens or even hundreds of tools. Lathe tools are placed into a turret, which can usually hold eight, ten, twelve or fourteen tools, depending on the size of the machine.
Turret is designed in such a way that it can hold all three types of lathe tools- external tools, internal tools, and tools that are used only at the machine centerline.
The arrangement of tools is very flexible in order to provide the best combination for any machining job. Both right hand and left hand tools can be setup in the turret.
