A bench mounted drilling machine is of the same type as a _____.

Explanation:

Correct Option Analysis:

The correct answer to the statement "A bench mounted drilling machine is of the same type as a _____." is Option 1: sensitive drilling machine. Let's explore why this is the case.

Bench Mounted Drilling Machine:

A bench mounted drilling machine, also known as a bench drill, is a type of drill press that is mounted on a workbench or table. It is designed for precision drilling operations and is commonly used in workshops, laboratories, and small-scale manufacturing environments. The primary features of a bench mounted drilling machine include its compact size, ease of use, and ability to perform accurate drilling tasks on small to medium-sized workpieces.

Similarities to Sensitive Drilling Machine:

A sensitive drilling machine is a type of drilling machine that allows the operator to "feel" the cutting action of the drill bit as it penetrates the material. This sensitivity is achieved through a hand-fed mechanism that provides greater control over the drilling process. Sensitive drilling machines are typically used for drilling small holes in delicate or thin materials where precision is crucial.

The bench mounted drilling machine shares several characteristics with the sensitive drilling machine:

• Precision: Both machines are designed for high precision drilling operations. The bench mounted drilling machine's stable base and adjustable settings allow for accurate hole placement, similar to the control provided by a sensitive drilling machine.
• Size and Application: Both machines are suitable for small to medium-sized workpieces and are commonly used in workshops, laboratories, and small-scale manufacturing settings.
• Ease of Use: Both types of machines are user-friendly, making them suitable for operators who require precise control over the drilling process.
• Hand-Fed Mechanism: While not all bench mounted drilling machines have a hand-fed mechanism, many do, allowing the operator to manually control the feed rate and pressure, similar to a sensitive drilling machine.

Based on these similarities, it is clear that a bench mounted drilling machine is of the same type as a sensitive drilling machine, making Option 1 the correct answer.

Analysis of Other Options:

Let's analyze why the other options are not the correct answer:

• Option 2: Deep Hole Drilling Machine

A deep hole drilling machine is specifically designed for drilling deep holes with a high depth-to-diameter ratio. These machines are equipped with specialized tools and techniques to handle the challenges of deep hole drilling, such as ensuring straightness, managing heat, and evacuating chips. Deep hole drilling machines are used in applications such as the manufacturing of gun barrels, oil and gas drilling equipment, and aerospace components. They are significantly different in design and application compared to bench mounted drilling machines, which are not intended for deep hole drilling.

• Option 3: Radial Drilling Machine

A radial drilling machine is a large, versatile drilling machine characterized by its radial arm, which can be swung around to position the drill head over the workpiece without moving the workpiece itself. This machine is designed for drilling large workpieces and allows for easy adjustment of the drill head position. Radial drilling machines are commonly used in heavy industries for drilling large and heavy components. The design and functionality of a radial drilling machine are quite different from those of a bench mounted drilling machine, making this option incorrect.

• Option 4: Gang Drilling Machine

A gang drilling machine consists of multiple drill heads arranged in a line or a group, allowing multiple drilling operations to be performed simultaneously on a single workpiece. This type of machine is used for high-volume production where multiple holes need to be drilled in a specific pattern. Gang drilling machines are commonly used in automotive and manufacturing industries for repetitive drilling tasks. The setup and purpose of a gang drilling machine differ significantly from those of a bench mounted drilling machine, which is designed for single-hole precision drilling.

In conclusion, a bench mounted drilling machine shares the most characteristics with a sensitive drilling machine, making Option 1 the correct answer. The other options represent different types of drilling machines with distinct designs and applications, which are not directly comparable to a bench mounted drilling machine.
