The quality of the stone will directly affect the quality of the finished product. If the material is not good, it is no good to use the best stone engraving machine. The engraving machine will give you an explanation of how the stone required for engraving distinguishes the quality of the material. You can make a preliminary understanding from the following aspects:
1. First observe the surface structure of the stone
If the surface structure is a stone having a coarse or unequal grain mechanism, the appearance of such a material may be poor. In addition, most natural stone will have some slight cracks, which are caused by the crustal movement of nature. Natural stone can easily break along these cracks. When selecting materials, you should pay attention to eliminate these cracked products. The stone material with uniform and fine structure is exquisite, the material is excellent, and the product is naturally better.
2. Size specifications of stone
Everyone knows the difficulty of splicing. In order to avoid affecting the splicing effect and the pattern, pattern and line deformation after splicing, it will affect the overall decorative effect. When purchasing stone, everyone should pay special attention to the control of the size rules. Measurement of stone.
3. Listen to the percussion
For most of the stone on the market, if it is a high-quality material with good quality, uniform internal density and no obvious micro-cracks, its knocking sound will be crisp and sweet. If there are obvious micro-cracks or fine veins inside the stone, or inferior stone that becomes loose due to weathering, the knocking sound will be rough.
4. A small method to check the pros and cons of stone
Drop a small drop of ink on the back of the stone. If the ink spreads out quickly, it indicates that the inner particles of the stone are loose or cracked. The quality of the stone is not good. On the contrary, if the ink drops do not move in the original place, the stone is dense and the texture is good.
