METHOD OF CUTTING MIRACLE PLATES (BRIGHT CUT PLATES) AND SETTING DIAMONDS THEREIN USING THE PUSH-SET METHOD FOR USE ON CASTED MOUNTINGS OF FASHION PIECES AND JEWELLERY.
TARA JEWELS LIMITED, a company incorporated under the Indian Companies Act, 1956, having its registered office at Plot No. 29(P) & 30(P), Sub Plot " A ", Seepz S.E.2., Andheri (East), Mumbai - 400 096.
The following specification particularly describes and ascertains the nature of this invention and the manner in which it is to be performed -.

This invention pertains to an unique method of cutting miracle plates (bright cut plates) and setting diamonds therein using the push-set method for use on casted mountings of fashion pieces and jewellery.
PRIOR ART:
Under the prior art plates are made mechanically by a process of stamping or manually using files. As the size of the plates is small, the facets are too close to each other resulting which the finish of the plate is not uniform. This in turn hampers the brightness of the plate.
INVENTION :
Under the present invention the applicant has created and innovated a bright cut plate called a Miracle Plate keeping in mind customers interest and satisfaction of buying jewellery which gives an appeal as if one is wearing diamonds bigger than its usual size and which have a sparkle-like shine.
The Miracle plates are CNC Machine cut plates in different shapes like round, marquise, square and triangle shape. The essence of this Miracle plates is its uniform sized facets which may be multiple in

number and which help in reflecting the bright light and giving a high shine and a sparkling effect around the diamond.
DETAILED WORKING PRINCIPLE :
This invention involves two processes : (a) the making of the bright cut plate named Miracle Plate and (b) setting of stones in the bright cut plate named Miracle Plate using the push-set method.
The technique of making the bright cut plate is undertaken using a CNC programmed machine which continuously cuts multiple plates from a single rod. Plates of desired dimension are manufactured considering only two major parameters i.e. outer diameter of the Miracle Plate and thickness of the Miracle Plate. For manufacturing a desired size of the Miracle Plate, a rod having an outer diameter more than 0.5 to 1 mm of the desired size is taken as a raw material in this process. This process is completely CNC program operated hence the CNC machine is programmed with the following parameters as mentioned below :-
a) Face Outer Diameter, b) Drilling Outer diameter, c) Y and Z axis parameters for holder movement, vertical and lateral, d) Degree of facets depending upon number of major facets (for example 8 facets

of 45° each), e) Offset/Change Y & Z axis for minor facets and f) Thickness of the plate.
To start this process we need to insert a desired size of the Rod (A) from one end of the machine and attach three different tools on a Multiple Tool Holder (B) facing the Rod (A), as depicted in Figure 1, for three different processes to be undertaken. The first tool is the Parting Tool (C) which faces the rod and makes the outer diameter. The second tool is the Drilling Tool (D) which while facing the rod drills a hole at the centre of the plate for diamond setting. The third tool is the Diamond Tool (E) which cuts through the plate at a desired angle for facet making.
The first Parting Tool (C) comes into operation for reducing the outer diameter of the Rod (A) in the desired diameter for example a 3.5 mm diameter Rod can be reduced by filing into 2.5 mm diameter plate. The Rod (A) is first put into a holder which holds the Rod horizontally. When the CNC machine is started, the Rod (A) starts to rotate. Parting Tool (C) which is a sharp tool touches the rotating Rod (A) thereby filing/reducing the outer diameter of the Plate (F) to the desired outer diameter, as depicted in Figure 2 and 2A. The Multiple Tool Holder (B) then slides down to a position as seen in

Figure 3 wherein the Rod (A) faces the Drilling Tool (D). The Drilling Tool (D) advances towards the centre of the Rod (A) and drills a hole of 0.8 mm in diameter into the same, as depicted in Figure 3A, thus making a slot for the diamond piece. There are certain plates which we do not want to be drilled, so the drilling operation is skipped in making such plates. After drilling the hole, the Multiple Tool Holder (B) slides down further to a position, as depicted in Figure 4, wherein the Diamond Tool (E) comes into operation. The cutting point of the Diamond Tool (E) comes at the centre of the Plate (F) and starts cutting the Plate (F) into 8 major facets with 45° angles adjusting itself as shown in Figure. 4.
Once the major facets are made, the Diamond Tool (E) moves in Y axis direction about 5.77 mm and in Z axis direction about 0.18 mm to cut the minor facets sideways. It creates 8 side facets but along one side only as shown in Figure 5. After completing the cutting of one side of the facets, Diamond Tool (E) again moves in Z axis direction with an offset of -0.18 mm which creates the other side of the minor facets and completes the design of the facet making, as depicted in Figure 5. After completing the above narrated three staged facet making operation using 3 different tools, the Parting Tool (C) comes into operation and cuts and finishes the Plate (F) from the

main Rod (A) and get a single Plate (F) which emanates the necessary shine, which is called as Miracle Plate. This process is repeated continuously through the use of the CNC machine till the entire Rod (A) is cut into bright and shining uniform sized and numbered facets. Each such plate (F) being termed for the purposes of this application as a Miracle Plate.
Sizes that can be manufactured-:
With the current set up the applicants are manufacturing Miracle Plates of varied dimensions ranging from size 1.5 mm outer diameter upto 6.00 mm outer diameter.


Multiple stone setting in Miracle plates
By changing the offset dimensions of the Drilling Tool (D), one can drill more than a single hole at the centre of the Miracle Plate (F) and accommodate more diamonds depending on the requirements.

TABLE 2
Setting of diamonds into this Miracle Plate (F) using the push-set method involves a procedure of masking the Miracle Plate (F) with the red masking solution to avoid any scratches or tool marks on the facets of the said Miracle Plate. Masking is undertaken using small painting brushes which carry the thick masking solution having property of becoming solid coating layer after drying which creates a thick layer protecting against any tool marks or scratches. Once the Miracle Plate (F) is ready with the masking it is inserted and assembled in the slot provided in the jewellery piece, as depicted in Figure 6. The centre hole of the Miracle Plate (F) is made bigger on top with the Round burr (G) of size 0.1mm or 0.2 mm less than the

size of the diamond to be set therein, as depicted in Figure 7. This gives it the necessary tightening effect while pushing the stone in the cavity. The diamond from its girdle is then slid at an angle into the hole and is pushed down into the cavity from one side first. Then the stone from its other side is pushed into the cavity such that the diamond fits into the Miracle Plate (F) resulting in the setting of the stone tightly into the cavity as depicted in Figure 8.
