What is a function of the toolchanger?

• A. Spindle
• B. Toolchanger
• C. Coolant Pump
• D. Chucker

Answer: (B)

A toolchanger is the mechanism that stores multiple cutting tools and automatically swaps them in the spindle as a machining program runs. Its purpose is to enable different operations—like turning, drilling, threading, or milling—without manual tool changes, so a single setup can produce the part efficiently and consistently. The control selects the needed tool and triggers the swap at the right moment, often using specific CNC commands. This automation is what makes the toolchanger the correct answer. The spindle simply holds and rotates the current tool, a coolant pump provides cooling during cutting, and a chucker refers to a type of lathe machine rather than a tool-swap mechanism.
