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 dipstick 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 so aligned with each other that the full facet is polished on the polishing lap exactly as it has been cut on the grinding lap.

OPTIONAL ACCESSORIES

The grinding lap, the polishing lap, dopsticks, dopstick stand, transfer block, and coolant attachments are not provided with the machine.

MAJOR ADVANTAGES

1. The indexing attachment is fitted on the dop stick itself and as such this affords a full view of the stone. This machine is best suited for mass production of Gems.
2. Also the individual expertise of the operator with respect to faceting or polishing can be best utilized to make them do what they are better at.
