Blank: stone with certain specifications, made of wool, used to process panels.

Wool (polished) board: a board sawn from wild wood.

Mirror plate (commonly known as large plate): a plate with smooth surface and mirror luster after polishing the wool plate.

Specification board: a board that meets the standard specifications.

(The specifications are generally: 600×600 and 800×800, the standard thickness is generally 20MM, or the size specified by the engineer is the highest price. )

(1) Flat plate: a square or rectangular flat plate.

(2) Special-shaped plate: non-square or rectangular polygonal plate.

(3) Template interface board: it is a standard board with complex shape (including arc) made according to specified drawings or board samples.

Special-shaped stones, mosaics, sculptures and mosaics are not discussed here.

Marble smooth board:

Selecting materials, shaping, frame sawing, splicing, gluing, screening, gluing, grinding and polishing by a mill, inspecting and warehousing.

Granite smooth plate:

Blank selection-trimming and shaping-sand sawing (feeding, sawing, sawing, discharging and discharging).

(selective screening and gluing)-grinding and polishing with a grinder-inspection-warehousing.

Smooth surface: After grinding and polishing, the surface is as smooth as a mirror.

Matte surface: the surface is smooth and dull, generally polished to 500# grinding head.

Antique surface: marble: polished with a grinding brush; Granite: after burning, polish it with a brush.

Sand blasting surface: the surface is even and gravel-like. It can be done by sandblasting machine, which can make words and patterns.

Burning surface (burning surface): after burning, the surface is mostly scaly, and the surface color is different from that of smooth surface. There are two kinds of hand-baked noodles and equipment-baked noodles. The former is used for irregular shapes and edges, while the latter is used for large plates.

Pickling surface: first polish with abrasive, then clean with hydrochloric acid and alcohol.

Chopping surface: it looks like the marks of an axe, and can be processed by hand or machine.

Litchi noodles: the surface is similar to the appearance of litchi, and it is processed by pneumatic engraving machine.

Hammer surface: the surface is uneven, so use a noodle burning machine to hammer.

Washing face with water: similar to burning face, but the stone surface does not change color. Water knife machine making.

Wire drawing surface: there are many grooves on the surface, which are machined by hand and Italian copying.

Natural fracture surface: the surface effect of waste edge skin.

Cutting surface: the surface of the saw blade is not polished after cutting. (it's hard to show it on the computer, look at the real thing)

Calculation formula of marble slab yield:

Output rate of each cube = 1000/ (product thickness+tool gap 5). 5 mm

For example, the output of 20mm slab is 1000/ (20+5)= 40 (M2/M3).

Calculation formula of granite slab yield;

Output rate of raw materials per square meter = 1000/ (product thickness+knife gap 8.5).

For example, the output of 20MM slab =1000/(20+8.5) = 35.08 (m2/m3).

The sales price of non-20MM board is based on 20MM board. When sawing slabs in batches, the price of 25MM slabs is = 1. 2 times 20MM slab price, 30MM slab price = 1.35 times 20MM slab price, 40MM slab price = 1.75 times slab price, 50MM.
