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

Cut

Diamonds are luxury goods. People are willing to buy them irrespective of high price because it is best suitable for jewelry. Why are diamonds on high demand for jewelry?     Diamonds sparkle better than any other jewelry today. They store light and sparkle. Today it is a luxurious status of having diamonds as necklace, bracelet, rings, etc. Cut plays a vital role in diamonds fire, brilliance and scintillation which we will discuss further. Cut is general terms means craft. Like any other material wood, limestone, etc; diamonds are also crafted. History:     Diamond cutting process has been known since 6th century in Indian subcontinent. In 14th century, diamonds were fashioned for jewelry.  Before 15th century it was cutting natural diamonds with other natural diamonds only. Slowly improvements were made and in 15th  century a tool called scaif was introduced by a Flemish polisher called Lodewyk Van Berquem. This tool is infused with diamond dust and olive...

Clarity

     Diamonds are formed with carbon and few other elements(nitrogen, boron, etc) along with some air, dust, packed inside it. These packed particles are called inclusions. They define the clarity (grade) of the diamond. In simple words, diamonds clarity grade depends on inclusion location, number of inclusions, inclusion color, inclusion shape and reflection. All these factors are considered under 10X magnification and a final grade is decided by the quality checker from the top view. Grades are as below: IF- Internally flawless VVS1- Very very small included 1 VVS2- Very very small included 2 VS1- Very small included 1 VS2- Very small included 2 SI1- Small included 1 SI2- Small included 2 I1- Included 1 I2- Included 2 I3- Included 3     Was it difficult to find the difference between IF, VVS1 and VVS2 clarities? This is how difficult it is to grade the diamonds in these higher grades. So quality checkers will use higher magnification upto 20X or more to find t...

Diamond Basic Knowledge

Diamond is a solid form of the element carbon with its atoms arranged in a crystal structure called diamond cubic. This carbon is a pure carbon. Carbon is not only the chemical element in diamonds but diamonds can also have nitrogen, boron, etc in their bond structure      Diamond has the highest hardness and thermal conductivity of any natural material, properties that are utilized in major industrial applications such as cutting and polishing tools. People often get confused between hardness and strength. Hardness is resistance to scratching or indentation whereas strength is to withstand force. Diamond is hard but not strong. It is impossible to scratch the diamond with any other substance except diamond which is basically hardness. It is easy to break the diamond with many substances which is basically low strength. Thermal conductivity is a measure of its ability to conduct heat. Due to stiff chemical bonds between light carbon atoms, diamond has an incredibly high t...
