Stone Diamond Tools

It is divided into two categories: manual quarring and blasting quarrying, or a combination of the two. Workers use diamond circular saws, diamond wire saws and other tools to separate the stone from the mine, and simply saw the separated stone to make it convenient for transportation. The large rocks quarried at this time are called blocks.

The large stones quarried are called blocks, which are usually cut and processed into stone slabs with a diamond disc saw. For marble, it can also be processed with an emery saw.

Diamond disc saws use a large disc-shaped saw blade inlaid with powder metallurgically bonded diamond particles. This kind of equipment can process super-hard stone and is relatively flexible to use. The disadvantage is that the diameter of the disc requires twice the height of the stone plus the diameter of the flange. It is difficult to manufacture a saw blade with a diameter that is too large, so it is not conducive to processing oversized specifications. Plate. The emery saw uses a row (multiple) of saw blades. Each saw blade is similar to the hand saw blade used by carpenters, but the emery saw has multiple strips arranged in parallel, and the intervals between each strip are equal to the thickness of the board. In this way, the sand saw The entire block of material can be sawed into many boards at one time.
The sawn boards are called rough boards or strips.

The purpose of grinding and polishing is to further process the sawn rough board to make its thickness, flatness and gloss meet the requirements. This process first requires rough grinding and leveling, and then gradually goes through semi-fine grinding, fine grinding, fine grinding and polishing to fully display the color and texture of the granite.
The main processing equipment is: automatic multi-head continuous grinding machine, diamond leveling machine, bridge grinder, disc grinder, reversing rough grinder, and hand grinder.
Diamond is generally used as abrasive. For granite polishing, diamond grinding blocks (also called grinding heads) bonded with composite materials are generally used for polishing. Generally, there are 1#, 2#, 3#, 4#, 5# and 0#, a total of 6 kinds of grinding blocks, 1# is the most Coarse, 5# is very fine, and 0# is a polishing paste that does not contain emery. The processing is generally carried out in sequence from 1# to 5#, and finally 0# is used for polishing.
Polished plates are called bare plates.

At this time, the stone already has preliminary commercial value, in order to better adapt to the needs of users. The stone also needs to be cut, chiseled, auxiliary processed, inspected and repaired, protected, etc. before it can be packaged and transported to the stone market.

Sometimes the stone needs to be processed on-site at the construction site, such as resizing or cutting corners. This is usually done using a portable cutting machine. For example, some stones need to be drilled, edged, etc., which are usually processed with a portable cutting machine or angle grinder.
