This set of Machine Tools Multiple Choice Questions & Answers (MCQs) focuses on “Radial Drilling Machine”.
1. The rigidness of radial drill machine is______ column drill machine.
a) less than
b) same as
c) more than
d) none of the mentioned
View Answer
Explanation: Radial drills can make large diameter of holes so its rigidness should be more column drill machine.
2. Thickness of valve in the radial machine is _____
a) small
b) large
c) can’t say anything
d) none of the mentioned
View Answer
Explanation: Valve thickness is quite large in this machine as it has to drill large diameter of holes.
3. There is a radial arm on the tubular column in radial drill machine.
a) true
b) false
View Answer
Explanation: As per the construction of this machine. On this radial arm, the spindle head is mounted.
4. Which type of movement is possible in case of radial arm?
a) only swivel
b) only up and down
c) all up, down and swivel
d) none of the mentioned
View Answer
Explanation: Only up and down movement is possible in this case. Generally, horizontal movement is not possible in radial arm.
5. The movement of radial arm is______
a) manual
b) powered
c) either manual or powered
d) none of the mentioned
View Answer
Explanation: Both movements are possible. But at the time when we have to deal with heavy and large workpieces the powered movement is more preferable.
6. Which of the following holds the drill spindle?
a) radial arm
b) tubular column
c) drilling head
d) none of the mentioned
View Answer
Explanation: Drilling head holds the drill spindle. There is a motor which is mounted on the spindle head rotates this spindle.
7. The drilling head can move_______
a) inward and outward
b) up and down
c) all inward and outward and up and down
d) none of the mentioned
View Answer
Explanation: These all types of motions are possible in this case. The drilling head is mounted on the radial arm.
8. Which of the following is not true for radial drill?
a) it can work with jobs, which are odd shaped
b) the tubular column is very thick and has small diameters
c) drill is mounted on drilling spindle
d) none of the mentioned
View Answer
Explanation: The tubular is thick but it has large diameter not small.
9. Which of the following is true for radial drill machine?
a) drilling spindle is subjected to rotation
b) the entire drilling head is mounted on radial arm
c) the gap between the drill and job is known as stroke length
d) all of the mentioned
View Answer
Explanation: All sentences are true. There is a one thing that we should know about radial drilling machine is that we can make multiple holes in one setting of work. This is the advantage of the radial drilling machine.
10. The radial arm can be rotated about the tubular column.
a) true
b) false
View Answer
Explanation: This is the property of radial arm. This arm can be lifted or lowered according to the requirements.
11. In radial arm, spindle may be_____
a) vertical
b) swiveling
c) swiveling and tilting
d) all of the mentioned
View Answer
Explanation: These all types of spindle are possible. The rotation of spindle is done by the motor mounted on the spindle head.
