Milling machine: where is the cutting tool mounted? Identify the correct component on which the milling cutter is mounted (general shop practice context). Choose the correct option.

Difficulty: Easy

Spindle
Arbor
Column
Knee

Correct Answer: Arbor

Explanation:

Shop context and assumption
In conventional horizontal milling machines, the cutter is mounted on an arbor, which is supported by the spindle and overarm. (In vertical milling, certain cutters mount directly in the spindle, but the common textbook answer for this general question is “arbor”.)

Final Answer
Arbor.
