Natural stone surface processing types
1. natural surface
Natural surface refers to the use of hammer and other tools to naturally split a stone from the middle, forming a shape such as the extreme uneven surface of natural stone, to maintain the natural mechanism of the stone processing method. The natural surface is very rough, and it is widely used in small blocks, roadside stones and other products.

3. Polished surface
Processing process: test selection -- rough grinding -- fine grinding -- fine grinding -- polishing -- inspection: Before the test selection, check the drawings, check whether the stone species, size and Angle limit tolerances of the semi-finished products meet the requirements, and then further check whether the tone and pattern on the polished surface are consistent with the semi-finished products of the same year, whether the quality defects such as missing corners, missing edges, cracks, color lines, and color spots meet the product quality requirements, and whether the surface has oil spots, rust and other pollution.
Fine grinding, fine grinding, polishing, respectively, in order with 200# metal disk, 400# metal disk, 500# resin disk grinding. During the fine grinding process, it is necessary to check frequently whether the surface being ground has eliminated the grinding marks of the former grinding disk. The grinding marks of the former grinding disk have been eliminated, and the process is completed. The key to fine grinding is to select a good 500# resin disc.
4. Surface fire
On the granite plate surface, through high temperature gas injection (i.e. flame injection method) processing a uniform, rough, bright color surface, this plate is called the fire plate. Its working principle is the use of hot gas flame (flame temperature of more than 20000°K, gas flow rate of 2500m/s) and stone surface contact formed thermal impact force, the use of different mineral particles in granite thermal expansion coefficient difference, when the flame spray its surface part of the particles thermal expansion loose off, Form a natural, convex degree does not exceed 1~1.5mm fluctuation and regular rough decorative pattern. It has a non-slip effect and can also play a role in weathering resistance due to high temperature treatment. This surface is mainly used for interior such as floors or as a finish for commercial buildings.
5. Matt surface
Matte surface plate is a kind of rough grinding and not smooth or cut with diamond saw, there is no brightness of the plate, generally rough grinding to 120 mesh, without fine grinding, fine grinding and polishing after several processing, and the more popular matte furniture effect is similar.
The processing technology is more similar to the polished plate, generally by sawing - thickness - rough grinding - cutting - edge grinding chamfering - inspection packaging - shipping or storage. The key is to master the number of rough grinding head, the rough grinding process required for the rough board sawn out by the big saw should start from the small number of mesh, generally from 24 mesh, 36 mesh, 60 mesh, and then to 120 mesh, and the plate processed by the machine cutting board can be processed by 60 mesh and 120 mesh rough grinding. Its operation method is the same as polishing plate. This kind of plate is widely used in outdoor floor, elevator entrance, corridor, lavatory and other places, mainly plays a non-slip function. In addition, this kind of product is also used in the decoration of furniture.
6. Sand surface
A kind of process effect made by stone sandblasting machine. The airflow size can be adjusted according to the hardness of the stone to reach the required depth and uniformity.
Product categories and mainly used in:
(1) Large wall carving, suitable for hotel, hotel lobby decoration, exhibition hall, museum exhibition hall layout, office, conference room interior decoration.
(2) plate carving, suitable for laying marble, granite plate of senior buildings inside and outside the walls, inside and outside the ground decoration. Through cutting and pattern splicing, add the change and vitality of marble and granite panels.
(3) non-slip floor, carved on the smooth granite surface of the light pattern to non-slip, while with a variety of geometric curves, more beautiful, can be used under the canopy, corridor, elevator door, bathroom and other places need non-slip function.
(4) Tablet inscription, monument, tombstone, cornerstone, inscription, tour guide plate and other text pattern engraving, based on natural stone, can be permanent without loss of beauty.
(5) Craft gifts, with granite, marble and other natural stone shaped processing, and with carving technology with special text patterns, as office, family interior decoration of arts and crafts.
7. Antique plane
As the name suggests, it is to take natural marble or granite and other old into an ancient look, according to the hardness of the texture of the plate to choose antique water immersion, that is, corrosive liquid, and then after grinding and polishing and other special treatment, so that it can reach or close to the natural weathering surface. The surface processing that mimics the antique effect of stone after a certain number of years is generally treated with an antique grinding brush or antique water, and the effect and cost performance of the antique grinding brush are generally higher and more environmentally friendly.
Flamed+ Brushed: fire first and then do antique processing.
Pickling+ Brushed: After pickling, antique processing is done.
8. Acid surface
The stone surface is corroded with strong acid to make it have small corrosion marks, and the appearance is more rustic than the polished surface. Most stones can be acid-washed, but marble and limestone are the most common. Pickling is also a way to soften the luster of granite.
9. Litchi surface
Use alloy knife to make a tool, artificial or machine hit the stone surface jump skin, so that the surface is rough, a little uneven; Or use a chisel to cut small holes densely on the surface, intentionally imitating the effect of water droplets dripping on the stone for years. It has a non-slip effect on the ground, deepens the rough and thick feeling in the wall, absorbs light and heat, has no large area reflection, and increases the three-dimensional sense.
10. Pineapple Face
Using an alloy knife to make a tool, artificial or machine hit the stone surface to jump skin, making the stone surface more uneven than lychee processing, just like the skin of pineapple.
11. Ax surface
Also called longan surface, a tool made of alloy sheets, artificial or machine regularly hit the stone surface to jump skin, into strips. Or use an axe to cut on the stone surface, forming a very dense strip texture, some like the effect of longan skin. Anti-slip effect.
12. Mushroom noodles
Generally, artificial cleaving is used, and the effect is similar to natural cleaving, but the sky surface of the stone is a plateau shaped shape with a depression around the middle. The surrounding teeth are clear, and the natural surface of the middle is fully raised, so that it has a rich three-dimensional and stable sense of firmness.
13. Groove surface tension
Also known as wire drawing surface, grooves of a certain depth and width are opened on the stone surface.
14. Surface waves
Roughly the same as the litchi surface, but deep concave, spot shape, strong three-dimensional sense.
15. Surfage planning machine
A long groove made by a special planer using alloy sheets. The effect of the finished product is really good, but it has been basically eliminated, time-consuming, high cost, waste of plate.
16. Face wash
Also called water flushing surface, a high pressure water jet stone surface, causing the mechanism of treatment. With high pressure water directly impact the stone surface, peel the soft texture of the component, forming a unique decorative effect.
17. Parquet noodles
18. tumbled
The surface is smooth or slightly rough, the corners are smooth and broken. There are several ways to achieve the tumbling effect. 20mm bricks can be rolled in the machine, and 3cm bricks can also be rolled and then split into two bricks. Marble and limestone are the preferred materials for tumbling treatment.
19. Rough-Rubbing
The surface is simply polished, and the machine cut lines formed in the process of cutting the wool plate can be ground without, and the feeling is very rough matte processing.
20, brush (Brushed)
Also known as water brush surface antique. The treatment process is to scrub the surface of the stone to mimic the natural wear effect of the stone.
