Which of the following are advantages of drilling on a milling machine instead of a drill press?

Selecting a milling machine for drilling tasks offers distinct advantages, particularly in terms of accuracy and rigidity.

Milling machines are designed for a wide variety of machining functions and typically come equipped for high-precision operation. This capability allows for tighter tolerances and more intricate features than a standard drill press, which is primarily intended for creating holes. The enhanced accuracy on a milling machine arises from its adjustable settings and stable cutting environment, making it suitable for critical applications in various industries.

Additionally, milling machines possess greater rigidity compared to drill presses. Rigidity is crucial when performing machining operations as it minimizes vibrations and deflections during cutting, which can negatively impact the quality of the workpiece and tool life. The robust construction of a milling machine contributes to its ability to withstand significant forces without compromising performance.

While cost is always a consideration in machinery selection, a milling machine is generally more expensive than a drill press due to its more complex design and versatility. Therefore, emphasizing accuracy and rigidity correctly identifies the primary advantages of drilling with a milling machine over a drill press.
