Faceting Machine- Jamb Peg


The machine base is made up of Cast Iron and is fixed with zinc coated steel legs with check nut to help in maintaining proper balance on any surface. ¼ h.p. 1440 r.p.m. Single-phase 220 volts motor AC 50 cycle. This motor is fixed on a removable base plate. The two housings contain two separate shafts driven by the same motor – but both these shafts can also be rotated in different directions with the help of an idler pulley. This pulley is adjustable and is also used in Tightening of the belt. One housing is used for fixing the diamond coated grinding lap of 8" dia. This housing is fixed. The other housing is for fixing the polishing lap of 6"- 8" dia. This housing is adjustable to match the height of the polishing lap to that of the grinding lap. The machine comes with faceting equipment consisting of a Facetor, which helps in maintaining the angles and has a cheater adjustment for fine tuning the alignment. The dop sticks are fitted with the indexing attachment.


This is the most versatile faceting and polishing machine for Gems. 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. The angles are changed subsequently and the same operation done again. Once the faceting is complete, the same operation is repeated on the polishing lap for achieving polish on the facets. The indexing attachment has the standard divisions to achieve various facets on the stone. The angle of cutting and polishing is controlled by using the facetor slots. 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. This machine is ideal for simultaneous faceting and polishing of gems in almost all conceivable shapes and is ideal for operator based adjustments for achieving higher yield and also for altering facets and angles at will for irregular shapes.


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


1. The indexing attachment is fitted on the dop stick itself and as such this affords a full view of the stone. Very sturdy base - the naked base alone weighs over 15 Kgs. This results in much greater stability and vibration free operation of the machine.

2. Since the faceting and polishing is being done with the same Facetor on the same base, the problems, those arise due to misalignments are not faced in this machine. The facets are fully polished in exactly the same way as they have been cut.
