key responsibilities
1. bench work & fitting
shaping & sizing: performing manual operations like filing, sawing, chipping, and scraping to bring metal parts to exact dimensions.
marking: using tools like scriber, vernier height gauges, and angle plates to mark guide lines for drilling and cutting according to blueprints.
accuracy: achieving high precision, often with a tolerance of � mm to � mm.
2. assembly & installation
mechanical assembly: fitting together components like gears, pulleys, shafts, and valves using fasteners (rivets, bolts, and screws).
interchangeability: ensuring parts can be replaced or interchanged across different units without individual custom fitting.
pneumatics & hydraulics: identifying and assembling components like compressors, valves, and actuators to build fluid power circuits.
3. maintenance & repair
preventive maintenance: regularly lubricating, cleaning, and overhauling machines (lathes, drill presses, grinders) to prevent breakdowns.
troubleshooting: identifying the root cause of mechanical failure, dismantling the unit, and replacing worn-out or defective parts.
testing: conducting performance tests on completed assemblies to ensure they meet operational standards.
