A large powerful drill press that has a single fixed spindle with an automatic feed is called a
Correct Answer
C. Upright drill press
Explanation
An upright drill press is a large and powerful drill press that has a single fixed spindle with an automatic feed. It is called "upright" because the spindle is positioned vertically and the workpiece is placed on a table that can be adjusted up and down. This type of drill press is commonly used for drilling holes in metal or wood materials with precision and efficiency. The term "upright" distinguishes it from other types of drill presses that may have different configurations or features.
2.
At type of drilling machine that has two or more drill presses mounted on a common base is called
Correct Answer
B. Gang drill press
Explanation
A gang drill press is a type of drilling machine that has two or more drill presses mounted on a common base. This allows multiple holes to be drilled simultaneously, increasing efficiency and productivity. The term "gang" refers to the grouping of the drill presses together. This type of drill press is commonly used in manufacturing processes where multiple holes need to be drilled in a single operation.
3.
A type of drill press that has several spindle that all revolve and advance at the same time, enabling several holes to be drilled at the same time, is called a(n)
Correct Answer
A. Multiple spindle drill press
Explanation
A multiple spindle drill press is a type of drill press that has several spindles that all revolve and advance at the same time. This allows for multiple holes to be drilled simultaneously, increasing efficiency and productivity. The other options, gang drill press, turret drill press, and radial press, do not accurately describe the specific feature of multiple spindles revolving and advancing together.
4.
A type of drill press that has a single spindle mounted on a movable arm that can swing around it's supporting post or column i called
Correct Answer
D. Radial drill press
Explanation
A radial drill press is a type of drill press that has a single spindle mounted on a movable arm that can swing around its supporting post or column. This design allows for greater flexibility and reach, as the arm can be adjusted to drill holes at various angles and positions. The term "radial" refers to the radial movement of the arm around the post. This type of drill press is commonly used in industries such as metalworking, where precision and versatility are important.
5.
A type of drill press that has several spindles that revolve around a common point, but which allows only one tool at a time to be in the operating position is called a
Correct Answer
C. Turret drill press
Explanation
A turret drill press is a type of drill press that has several spindles that revolve around a common point. However, it only allows one tool at a time to be in the operating position. This means that the operator can easily switch between different tools without having to manually change them. The turret drill press is commonly used in situations where multiple drilling operations need to be performed quickly and efficiently.
6.
The part of the drill press that revolves and also carries the drilling tool is called the
Correct Answer
A. Spindle
Explanation
The correct answer is spindle. The spindle is the part of the drill press that rotates and holds the drilling tool. It is responsible for driving the tool into the material being drilled. The spindle is an essential component of the drill press, as it provides the necessary rotational motion for drilling operations.
7.
The part of the drill press that causes the drilling tool to move up and down is called the
Correct Answer
B. Quill
Explanation
The part of the drill press that causes the drilling tool to move up and down is called the quill. The quill is a vertical component that holds the drill bit and can be adjusted to control the depth of the hole being drilled. It is connected to the spindle and moves along with it, allowing for precise drilling operations. The spindle, collar, and drill holder are other parts of the drill press, but they do not directly control the up and down motion of the drilling tool.
8.
A 16" upright drill press
Correct Answer
A. Can drill a hole in the center of a 16" diameter circle
Explanation
The correct answer is "can drill a hole in the center of a 16" diameter circle." This answer is correct because a 16" upright drill press refers to a drill press with a maximum drilling capacity of 16 inches. Therefore, it can drill a hole in the center of a circle with a diameter of 16 inches.
9.
An 8' radial press
Correct Answer
B. Can drill a hole in the center of a 16' circle
Explanation
The correct answer is "can drill a hole in the center of a 16' circle." This is because an 8' radial press has an arm that measures out 8' from the center of its column to its tip. This means that the arm can reach a distance of 8' in any direction from the center. Since the radius of a circle is the distance from the center to any point on the circumference, the arm of the press can reach a radius of 8'. Therefore, it can drill a hole in the center of a circle with a diameter of 16' (which is twice the radius).
10.
A drill bit that drills round holes with flat bottoms is called?
Correct Answer
A. Forstner bit
Explanation
A drill bit that drills round holes with flat bottoms is called a Forstner bit. This type of bit is specifically designed to create clean and precise flat-bottomed holes, making it ideal for woodworking projects that require a flush finish. Unlike twist bits or hub bits, Forstner bits have a unique design with a center point and sharp cutting edges that allow for accurate drilling without splintering or tearing the wood. Therefore, the correct answer is Forstner bit.
