Worked Solution & Example Answer:10.1 State THREE effects of insufficient lubrication of pedestal drilling machines - NSC Mechanical Technology Welding and Metalwork - Question 10 - 2022 - Paper 1
Step 1
State THREE effects of insufficient lubrication of pedestal drilling machines.
Answer
-
Rusting of components: Insufficient lubrication can lead to corrosion and rusting of the machine components, which compromises their integrity over time.
-
Movement between parts will be affected: Lack of lubrication causes increased friction between moving parts, leading to potential jams or reduced efficiency.
-
Excessive wear and seizure of moving parts: Components may wear down significantly or seize up completely, resulting in costly repairs and downtime.
Step 2
State THREE effects of overloading on a bench grinding machine.
Answer
-
Resulting in malfunction of the machine: Overloading can cause the machine to malfunction, leading to safety hazards and interruption of operations.
-
Excessive wear and reduction of machine lifespan: Operating beyond its designed capacity accelerates wear and can significantly shorten the operating lifespan of the machine.
-
Damage to grinding wheel: Overloading can cause the grinding wheel to crack or break, making it unsafe and ineffective.
Step 3
State TWO general maintenance guidelines for a power-driven guillotine.
Answer
-
The machine should be tested for correct operation: Regularly testing the machine ensures that all components are functioning properly and safely.
-
Lubrication points should be serviced: Ensuring that lubrication points are regularly serviced enhances the efficiency and longevity of the machine.
