What tool is predominantly used to machine keyways in hubs or bores?

Lathe
Milling machine
Drill press
Band saw

The correct answer is: Milling machine

The milling machine is predominantly used to machine keyways in hubs or bores due to its ability to achieve precise cuts and shapes. Keyways are grooves that are machined into a shaft or hub to allow for the secure attachment of gears, pulleys, and other components. Milling machines are designed for intricate cutting operations with various types of cutters, such as end mills, which can effectively create keyways of different widths and depths. The capability of a milling machine to handle both horizontal and vertical movements allows for greater flexibility in machining shapes accurately, making it the ideal tool for this specific task. In contrast, a lathe is primarily used for turning operations and is less suited for making flat bottomed keyways. A drill press is designed for drilling holes and lacks the versatility needed for milling operations. Similarly, while a band saw is used for cutting materials, it is not capable of creating the precise and controlled machined grooves characteristic of keyways. Therefore, the milling machine stands out as the most appropriate tool for this application.
