Difficulty: EasyParaphrased Fact Recognition

Before operating an industrial milling machine, technicians must inspect the emergency shutoff mechanism to confirm it responds immediately. Regular lubrication of the spindle prevents friction buildup that could warp metal components during high-speed cutting. If abnormal vibration occurs during a run, operators are instructed to halt the equipment at once rather than completing the cycle. Adhering to these protocols significantly decreases the risk of mechanical breakdowns and ensures operator safety.

According to the passage, what protects metal components from becoming distorted during high-speed cutting?

  1. A
    Disconnecting the main workshop electrical breaker
  2. Routine oiling of the spindleAnswer
  3. C
    Completing the cycle after noticing abnormal vibration
  4. D
    Allowing friction to build up gradually over time

Answer

Routine oiling of the spindle
The passage directly states that 'regular lubrication of the spindle prevents friction buildup that could warp metal components.' The correct option accurately restates this fact using the synonym 'routine oiling' for 'regular lubrication.'

Step-by-Step Solution
