How To Cut And Polish Rocks?

Stones are cut and polished according to their uses. For instance, for jewelry, the process is milder than that of installing a granite countertop.

Cutting and polishing rocks are quite easy. After taking the necessary safety all you have to do is to follow the procedure:

Step 1

First, Scratch a gemstone with a thin circular blade composed of steel or copper. That too impregnates with diamond grit along the outer edge. 

This also revolves at several thousand surface feet per minute. It is the most typical method of gem sawing. 

A liquid, such as oil or water, helps to wash away cutting waste. Also, keeps the rock and saw blade from overheating. Which, by the way, could cause damage to both of them.

Step 2

Grind the rock to the desired rough shape with a grinder. For bigger pieces, a manual grinder stands high.

Although an all-in-one grinder/sander/polisher can save time. That too by many procedures into one machine. 

This process is very significant as it decides the longevity of your stones. I don’t want you to regret skipping this process and struggling while cleaning the stone tile floor.

Step 3

Make a flat bottom on a rock piece with a lap. It’s a sander for flat sanding.

In order to prepare for a setting, the stone is used to level down the bottom. You may need to polish likewise if the lap creates unfortunate edges.

Step 4

Sanding is similar to grinding, except that the abrasives are finer. Its job is to remove deep scratches left behind by coarser abrasives while grinding.

Because it removes more material. It enables the rock to be sculpted more delicately before polishing.

On rounded rock, a flexible surface, such as a belt sander, is employed. Its purpose is to prevent flat areas from forming and to encourage smooth curves.
