Question 657General Subjects - Assistant Engineer
70% to passOne of the steps required to increase the drilling speed of a drill press is to _______________.
Achange the terminal connections of the drive motor
Bmove the drive belt to a smaller diameter motor pulley
Cchange to a larger diameter spindle
Dmove the drive belt to a smaller diameter spindle pulley
AI Explanation
The correct answer is D) move the drive belt to a smaller diameter spindle pulley. Increasing the drilling speed of a drill press can be achieved by moving the drive belt to a smaller diameter spindle pulley. This reduces the spindle speed, resulting in a higher drilling speed. The other options are incorrect because they do not directly affect the drilling speed - changing the terminal connections of the drive motor or using a larger diameter spindle would not increase the drilling speed, and moving the drive belt to a smaller motor pulley would actually decrease the drilling speed.
