Filigree craft is a fine gold process that processes gold and silver into silk, and then makes gold and silver jewelry by means of coiling, pinching, filament, and stacking. According to the different decorative parts can be made of different patterns of filigree, arch wire, bamboo silk, wheat ear silk, etc., the production method can be divided into pinching, filling, saving, welding, stacking, base, weaving, weaving, weaving, etc.
1. Filigree is to pinch the groove made of filigree into various patterns such as plum blossoms, peony flowers, birds, dragons and phoenixes, pavilions and pavilions.
2. Filament filling is to fill the filigree that has been pinched and flattened in the design outline. Commonly used types are arch filling, petal filling, etc.
3. Welding is the process of putting together the patterns made and forming a complete jewelry through welding.
4. The stacking is the process of using the method of stacking charcoal ash to wind the code wire evenly on the charcoal ash shape, build out various shapes, and use a small sieve to sieve and weld the medicinal powder.
5. Weaving is to weave the edge patterns of gold and silver filament and the shading of different shapes, and then glue different patterns and patterns made by various technological methods on the shading, which is completed by welding.

Summary. Causes: (1) The diameter of the bottom hole is too small, and the tap is not easy to cut into the orifice (2) When tapping the second cone, the thread that has been cut out is not screwed in (3) The thread is skewed too much, and the tap is forcibly corrected (4) The toughness material is not cooled and lubricated or the chip is not broken and forcibly attacked, and the thread that has been cut is broken (5) The edge of the tap is blunt.
Prevention method: (1) select a reasonable bottom hole diameter according to the workpiece material (2) when tapping the second cone, first screw the second cone along the thread cut out by hand, and then slowly attack (3) when starting to attack, the force of both hands should be balanced, and check the perpendicularity between the tap and the surface of the workpiece (4) the ductile material plus cooling lubricating fluid, and invert the tap more to break the chips (5) grind with an oil stone or grinding wheel.
The thread tap is not sharpened well.
Can you elaborate on that a little bit more?
The causes are: (1) the diameter of the bottom hole is too small, and the tap is not easy to cut into the orifice (2) when tapping the second cone, the thread that has been cut out is not screwed in (3) the thread is skewed too much, and the tap is forcibly corrected (4) the ductile material is not cooled and lubricated or the disturbing chips are not broken and forcibly attacked, and the cut thread is broken (5) the tap edge is blunt. Prevention method:
1) Select a reasonable bottom hole diameter according to the workpiece material (2) When tapping the second cone, first screw the second cone into the thread along the cut out by hand, and then slowly attack (3) When starting to attack, the two hands should be balanced and check the perpendicularity between the tap and the surface of the workpiece (4) The ductile material is cooled with a vibrillation cooling fluid, and the tap is reversed more to break the chips (5) Grind with a stone or grinding wheel.

The filaments are part of the stamens. The structure that supports the anthers. It is generally filamentous, but there are also conzygosis cylindrical (e.g., most malvaceae and leguminosae).
There is usually a vascular bundle. Each stamen, composed of filament and anther (anther) two parts, among them, the filament is slender and filamentous, its outside is a layer of epidermal cells, and keratinized, often epiphytic hairs, stomata, etc., the inside is full of parenchyma cells, ** there is a three-dimensional tube bundle through. (as shown in the image).

Explanation of filaments The lower part of the stamens is mostly filamentous, and its role is to support the anthers. (See 'Flowers').
