What is the gemstone grinding, peeling and polishing equipment with outer skin?

Shenzhen Jinxin answers the plane grinding problem for you: the sapphire grinding and polishing pressure is calculated according to the area, and the pressure per unit area.

There is a special polishing point, put the jig in the grinder, put it in it, and it's OK

Polishing directly with a polishing machine.

There is also a domestic land, relatively mature technology or a good point of import, the stability is relatively good, mechanical and chemical polishing is mainly for the processing of semiconductor products.

Precision parts can be machined with a magnetic grinding machine. 1: Excellent and fast removal of burrs around the workpiece.

Including small inner holes, pipe holes, and dead angles. 2: The grinding workpiece does not affect the original accuracy; There will be no change in shape and size.

The surface roughness value can be reached, and the surface shows a bright metallic luster. 3: The time is short.

Each processing time is 5-20 minutes4: Convenient and simple operation; The workpiece is processed in batches at one time, and the cost is extremely low; No pollution; Stainless steel needles are long-lasting abrasive materials. 5：

After processing, the finished product will never be deformed, the surface will not be damaged, and the accuracy will never be affected. 9: The models are complete, and special models can be designed.

Kunshan Qixin grinding machinery.

The answer upstairs is not comprehensive enough, ultra-precision grinding and polishing not only uses chemical polishing, but also needs to be combined with physical polishing to achieve a more ideal effect. Moreover, some special materials cannot be chemically polished, because chemical polishing is acid and alkali corrosion, which may have a series of effects such as pinholes and blackening when targeting a certain workpiece. Chemical polishing is now widely used in the market, including silicon wafers, semiconductor materials, optical lenses, watch hardware, stainless steel castings, as well as iron oxide products, copper, and the United States Universal is only a well-known company upstairs, and the representative products are zox-n is weakly acidic.

The advantages of ultra-precision grinding and polishing technology in similar processing technologies.

Shenzhen Hyde is a professional manufacturer of grinding and polishing machines, as a relatively senior enterprise in the industry, today Hyde is here to share with you the advantages of ultra-precision grinding and polishing technology in similar processing technology? Can other technologies replace ultra-precise grinding and polishing techniques?

It can be seen from the application of different technologies in some well-known domestic manufacturers to process the effect of precision metal mirrors, and the ultra-precision grinding and polishing technology has great advantages over other processing technologies.

It is not difficult to find that this grinding and polishing machine with ultra-precision grinding and polishing technology has great advantages compared with other processing technologies, and its advantage is mainly that this process technology adopts domestic leading technology, especially for the polishing of sapphire substrates, which has great advantages.

High-precision plane grinding and polishing machine is a kind of precision polishing equipment, and the workpiece and the grinding machine do relative friction to achieve the purpose of grinding and polishing.

The grinding and polishing machine polishes the sapphire substrate for a variety of materials, such as silicon wafers, molds and light guide plates, etc., which are different according to the specific parameters set by various materials.

Sapphire substrate polishing machine according to the principle of sapphire hardness is higher, and easy to break the principle to set the parameters, it is necessary to ensure that the pressure is moderate, the grinding speed can not be too high, to ensure that there are no scratches, no broken edges and other characteristics, its main advantage is also the use of PLC program control system, touch screen operation panel, the speed and timing used can be directly operated on it.

It can be seen that ultra-precision grinding and polishing technology is irreplaceable by other technologies, and the prospect of ultra-precision grinding and polishing is immeasurable. Hyde welcomes customers to come to sample!

(1) The shape of special-shaped gemstones.

There are two types of special-shaped shapes: free type and random shape.

The freeform is a shape that people deliberately think about according to the natural form, color, and color shape of the rough stone (see Figure 5-1-51). Freeform is further divided into free-faceted and carved according to the tools and methods used.

Figure 5-1-51 Special-shaped cut.

Shape is a simple way to polish and polish the shape of the rough stone given by nature. Ornamental stones such as rain flower stone and Three Gorges stone are with the shape stone.

2) The processing process of special-shaped gemstones.

1.Processing of free-type gemstones.

1) Free faceting type.

Most free-faceted gemstones are high-grade gemstones, such as diamonds, rubies, sapphires, opals, etc. The main processing steps for free-faceted gemstones are: roughing, grinding and polishing.

Rough is to remove the outer skin of the rough gemstone, cut off large cracks and impurities, so as to obtain the general shape of the gemstone (rough). The grinding sequence is similar to that of faceted gemstones, where the rough is glued to one end of the sticky rod and half of the stone is ground and polished. Then turn the blank, grind and polish the other half.

For oddly shaped shapes, it is sometimes possible to grind and polish them separately in several parts.

In free-faceted gemstones, there are many and irregular facets, so it is important to remember the angle and hole position of each facet so that the subsequent polishing can proceed smoothly. Or polish one side for each side of grinding.

2) Carved pieces. Carvings are designed according to the similarity between the shape of the gemstone material and certain animals and plants. The main material of the carvings is jade, but there are also gemstone crystals, such as Guanyin carved from tourmaline crystals, flowers, insects and birds carved from crystal crystals.

The process of carving is the gemstone carving process, which is described in detail in the next chapter.

2.Processing of shaped gemstones.

There is no restriction on the raw materials of the type gemstones, high, medium and low-grade materials. This shape not only preserves the weight of the gemstone to the maximum, but also allows the human imagination to be unleashed.

The shape of a conformal gemstone is basically determined by the shape of the rough itself. Generally, only the edges and corners can be polished and polished, so the process is relatively simple. Both its grinding and polishing are done using a roller. The method is the same as that of pearl gemstones.
