Laser operator

Laser operator deals with the rough or window polished or laser sawn diamond. Follows planners' laser marking to laser saw and return back to the planner.

This task is performed because of following reasons:
  • Cut the diamond into planned pieces.
  • Cut big reject part where polishing it will consume more time



Responsibilities:

  • Check every parcel have diamond when receiving parcels from stock controller
  • Check weight of diamond in weighing scale and confirm if it matches with the current weight mentioned in the parcel
  • Be sure that you fully understand laser marking and label instructions by the planners
  • Consumables, tools and equipment are available and in good condition
  • Calibration is mandatory everyday in the morning before production
  • Cover your laser machine and shut down machine with technician help when going for long holidays
  • Ensure the aircon in the room is always on 18°-21°C
  • Ensure your room is clean and tidy before knocking off for the day
  • After planner/ section monitor/ section supervisor confirmation check current weight using weighing scale and write it in the parcel

Consumables, tools and equipment:

  • 0.5 Marker pen
  • Consumables for fixing the diamond in pot (Different factories use different consumables)
  • Pots in all sizes you laser saw
  • 10X or more magnifier loupe
  • Apron or dust coat
  • Regular pen and book to note down any instruction from monitor or supervisor
  • Cloth for cleaning
  • Power meter
  • Black plate or anything similar to check spot
  • Pollution meter
  • Whitener
  • Whitener cleaning liquid
  • Weighing scale
  • Fixing station with their tools(Lens, etc)
  • Long blade
  • Water
  • Tension meter
  • Emery paper or anything similar
  • Oven
  • Kettle
  • Twinsavers or anything similar
  • Laser machine

Calibration:

    Power check:

  • Power checking is primary task for any operator before laser sawing.
  • Ensure the power is off from the laser beam
  • Connect the power meter
  • Open the laser machine door and insert the sensor exactly under the laser beam. Use the keyboard arrows to move the laser beam cursor available on the screen
  • Select maximum power profile
  • Focus on the sensor
  • Now switch on the power from the laser beam and the power meter will display the power output from the machine
  • If your maximum power is 21 watts then the power meter should display between 20.5 to 21.0 watts
  • Power fluctuating should not go beyond 2.0watts which means you do not have stable power which can result in damaging the diamond
  • You can work and laser saw the diamonds though the above 2 points did not qualify but on your own risk because the technical support team for the machines do not encourage to work if any of the above 2 points do not qualify
  • Similarly do for the profile which you use for laser sawing
  • Switch of the power from the beam
  • Now you completed power checking and note it down in your book
  • Remove the sensor and the power meter and store them back to their place

    Spot check:

  • Insert black plate which can withstand laser beam power under the laser beam. Use keyboard arrows to move the laser beam cursor available on the screen
  • Select the profile which you use for laser sawing
  • Focus on black plate
  • Now power on the laser beam and click on spot
  • You will see a tiny hole on the black plate
  • Check if the hole is in middle of the cursor on the screen. If not adjust the cursor and ensure the hole is in the center
  • Now locate to another place on the black plate and Spot check again
  • Check if the hole is in middle of the cursor on the screen. If not adjust the cursor and ensure the hole is in the center
  • If hole is not in center then call the technician for support
  • Your spot checking is completed and note down in your book

Grains

Grains play a vital role in manufacturing diamond in terms production and quality. If the diamonds are not polished in proper direction will impact the time taken to polish it and might lead to damage of diamond none tension What are grains and its basic knowledge:     Grains are arrangement of fibers in a material. Diamonds have grains like any other material.  If you can crack open the knowledge of grains in diamond then you can be highly skilled polisher or planner. Before we understand grains in diamond lets understand grains in wood.      Wood can be cut from any direction where few directions are easy and others are difficult(rarely impossible). It is very easy to cut the wood along the grains and very difficult cutting across grains. So when you are cutting wood using hand saw blade, you will first find the grains and then cut it along. Similarly, we need to know the grains before cutting or polishing the diamond. Below is a 3D image of diamond ...

Repair polisher

Follows finishing supervisor instructions written in parcel to polish and return back to the finishing supervisor. They will confirm if polisher polished according to the instructions and the diamond need anything more to be polished and then send it to the section QC for polish and symmetry quality check. This task is performed because of following reasons: Ensure parameters, polish and symmetry are met as per rough estimations Responsibilities: Check every parcel have diamond when receiving parcels from stock controller Check weight of diamond in weighing scale and confirm if it matches with the current weight mentioned in the parcel Be sure that you fully understand finishing supervisor instructions written in parcel Consumables, tools and equipment are available and in good condition Opening the scaif should be done just before shift end so that you are ready for tomorrow Cover your scaif and oil your tang when going for weekend or holidays Ensure your polishing mill is clean a...
