OPERATIONAL DETAILS

This is the most versatile faceting and polishing machine for Gems. This is an ideal machine for mass production of gems wherein the work is dived between Four operators. Two operators are faceting the stone sand the other two are polishing the stones.

The Gemstone is fixed on to the Brass dopstick with the help of dopping wax. This dopstick comes with an indexing attachment. One end of the dop stick has the stone and the other end of the dopstick is rested in the respective slot provided in the facetor unit. These slots provide for different angles at which the stone is required to be cut and polished.

The indexing attachment on the dop stick is rested and supported against the cross arm of the facetor. The indexing attachment is operated to get the different facets. Once the faceting is complete, these dopsticks are handed over to the operators who will be polishing these Gems on the polishing lap for achieving polish on the facets. The facetors are aligned with each so that the stone is polished on the polishing lap exactly as it has been cut on the grinding lap. The motor rotates the cutting lap and the polishing lap. The speed of rotation of either or both the laps can be changed with the help of step pulleys provided with the machine.
