A spindle with a material attached rotates as a CAD program controls a multi head tool changer to remove material. Which machine is this describing?

• A. CNC lathes
• B. CNC milling machine
• C. CNC router
• D. Water jet cutting

Answer: (A)

Turning involves the workpiece rotating on a spindle while the cutting tool does the material removal. The description’s rotating spindle with material attached points to a turning process, and the CAD-controlled multi-head tool changer fits the way a CNC lathe switches between tools for different turning operations in one setup. In contrast, a milling machine or router uses a rotating cutting tool while the workpiece stays mostly fixed, and water jet cutting doesn’t use a spindle at all. So this setup is best described as a CNC lathe.
