The machine base is a sturdy Cast Iron base, which forms the machine table and is suitablysupported by a sturdy steel angle frame. ¼ h.p. 1440 rpm single-phase 220 Volts AC-50 cyclemotor to drive the grinding lap. One tiny DC motor to drive the work piece. A central housingthat contains the main shaft driven by the main motor, the r.p.m. of which can be adjusted withthe help of step pulleys provided. The main facetor of the machine is mounted on a bearingpedestal on top of two cross slides made of sturdy cast iron. All this is mounted on a bearinghousing for a separate angular movement. The master template is fixed to the back of the colletand is supported by a revolving base. Separate templates are supplied for different shapes. Themachine is fixed with the light attachment and a control panel, which contains the variouselectrical switches and a pilot lamp. The machine is fixed with coolant splashguards and coolantre-circulation system.OPERATIONAL DETAILSThe Gemstone is fixed on to a metal (brass/iron) dopstick with the help of a two compound epoxy glue. Dopstick isheated for glue to settle and fix the stone. The dop stick with stone is then inserted into the collet in the facetor andlocked. The electrical connections are so designed that as soon as the facetor is brought nearer the grinding lap, thefacetor motor starts operating. Stone is then ground on the grinding lap in accordance with the shape of the templateused. The motors help in rotating the grinding laps, the work piece, the master template for the shape etc. Loadingand un-loading of the stone and the angular movement are to be done manually.

The cross slides - like that of a lathe machine - are used for:

1. Setting the correct desired size of the stone - calibration. All stones operated on this setting willproduce same size stones.
2. Setting the height of the dome of the cabochon. This means that one can make cabochons of differentdome heights with the same master template.The machine is ideal for shaping and calibrating gems in virtually any shape including cabochons.

MAJOR ADVANTAGES

1. This machine makes cabochons on a standard 8" dia-grinding lap as against the expensive variationsused in other machines.
2. This machine uses a two dimensional template as against expensive 3-dimensional templates used inother machines. This machine uses only one template for many different heights of domes ofcabochons. Other machines need different templates for different dome heights.
3. This machine doubles as a calibration and pre-shaping machine with minor adjustments that can bedone by the user.
4. This is a very user-friendly machine capable of many options all rolled into one package.

OPTIONAL ACCESSORIES
The grinding lap, dopsticks, dopstick stands, heater and glue are not provided with the machine.

Standard equipment & accessoriesthe machine base is made up of cast iron and is mounted ondull finish mica fixed board which forms the table with heavysupporting legs. There are two motors - one is 1/30 h. P. 1400 r. P. M. Single-phase220 volts motor ac 50 cycle – used for rotating the faceting andpolishing rollers simultaneously and the other, a small dc motorused for back and for the linear reciprocating movement of thepolishing plate while polishing. The machine is fixed with a highly accurate faceting head whichis moved back and forth and sideways with the help of slideswhich can be pre-set for the required distance. Operational detailsthe gemstone is fixed on to a metal (brass/iron) dopstick with the help of dopping wax. The dopsticks are fixedwith the indexing attachment. The faceting head has the numbered slots for different angles. One end of the dopstick is inserted into these angle slots and faceting and polishing is done according to the shape and size andrequirement of the cutting styles. Various types of indexing attachments are available to achieve virtually anydesired shape and cut. The faceting and polishing rollers also come in a variety of sizes ranging from ½” dia to 1-1/4” dia. The number of options available for different cutting styles is enormous. The operator has only to use hisimagination to achieve almost any style of cut. This is made possible by the angular shifting of the faceting head orthat of the faceting and polishing rollers – provisions are given in the machine for bothoptional accessoriesthe faceting rollers, the polishing rollers, dopsticks, dopstick stand, and transfer block are not provided with themachine and have to be procured separately at extra cost. Most stones have a flat table and this can not be done onthis machine – hence some other machine (we recommend our aew-fpid model, as this machine is equipped witha similar faceting head) is required for this purpose. It is also our experience that for the sake of variety, people wantonly some of the facets to be concave cut and others to be flat cut – or they prefer the crown side to be flat cut andthe pavilion side to be concave cut – in such cases also, the other machine for flat cutting and polishing isrequired.


Major Advantages:

1. Excellent machine for concave faceting & polishing of virtually any size and shape.
2. The first machine for simultaneous faceting and polishing- without the need to change rollers – results in higheroutput and greater accuracy of the stone. Adapted to work on the facetors and dopsticks presently being used inthe processing of normal faceted stones – results in lesser investment for back end operations.
3. Also suitable for twisted faceting & polishing to a high degree of accuracy.
