The production process of the stone bracelet is as follows:
Material selection
Have a preliminary understanding of the color, texture and cracks of the stone. Only materials without large fissures or cracks can be used as raw materials for making bracelets. Carefully examine the materials, apply techniques according to the materials, and determine whether it is suitable for making bracelets.
For instance, when picking up stones to make bracelets in the Gobi Desert, try to pick larger materials and check if there are any cracks. Since they will crack as soon as you drill, you should prepare more materials.
Slice
When cutting the surface of materials with a jade cutting machine, the blade is coated with a layer of diamond sand, which can accurately and quickly perform the cutting.
Based on the direction of the material's color band, the grid pattern, and the planned quantity of the bracelet, etc., the material is first planned for the cutting method, and then the material is cut into slices using a cutting machine, with each slice reaching the thickness of the bracelet. Common slicing methods include slice cutting, wire cutting and thallium cutting.
Positioning
Carefully inspect each piece of material, avoid cracks, select the most suitable position for design, and draw the shape of the bracelet. This is a very important step in making a bracelet. It is necessary to ensure that the entire bracelet has no flaws or patterns.
The specific operation is to draw the shape of the bracelet on the sheet material, select the part with the best water or color, and determine the diameters of the outer and inner rings of the bracelet.
Embryo suction
Suction of the outer blank: Place the sheet material marked with the bracelet position on the diamond drill lathe, and use the drill bit corresponding to the outer circle diameter to press down and suck out the entire bracelet shape.
Suck out the inner blank: Select a drill bit based on the diameter of the inner circle, suck out the inner circle to form the initial shape of the bracelet. The middle part sucked out is called the "bracelet core".
"修形" 可 以 翻 译 为 "shaping"
Topping: Remove the edges and corners of the bracelet and grind it into a smooth shape.
Edge tapping: Adjust the curvature according to the type of bracelet (round or flat), and the Angle and force used during the shaping process are also different. After the blanking process is completed, the marks on the rough blank should be ground smooth and the shape should be completely set from the inside out.
Grinding and polishing
Polish the polished bracelet back and forth several times until it reaches the desired brightness.
Waxing
Soak the bracelet in warm wax and boil it. After waxing, take the bracelet out of the pot to make it brighter.
