2024-03-15 14:42:51

Throughout human history, gemstones have always played an important role. Whether used as jewelry, crafts or decorations, gemstones are a shining part of human civilization. To transform raw gemstones into gorgeous works of art requires exquisite processing techniques. In this article, we explore how gemstones are worked, revealing this ancient and mysterious art and skill.

1. Preparation

The first step in working with gemstones is preparation. This includes selecting suitable gemstone raw materials, cleaning and inspecting the gemstones to ensure that their texture and shape meet processing requirements. At the same time, you also need to prepare the corresponding tools and equipment, such as grinding discs, saw blades, grinders, etc.

2. Cutting and sawing

Cutting is one of the key steps in gemstone processing. Cut the raw stone into the desired shape and size by using a saw blade or other cutting tool. During this process, special attention needs to be paid to maintaining the integrity and beauty of the gemstone and ensuring the accuracy and finesse of the cutting.

3. Lapping  and Grinding

Polishing and grinding are important steps in processing gemstones, which can make the surface of the gemstone smooth and shiny, and highlight its color and inner beauty. At this stage, it is necessary to use various grinding discs and abrasives with different particle sizes, select according to the hardness and texture of the gemstone, and gradually carry out coarse grinding, medium grinding and fine grinding until the desired effect is achieved.

How to choose gemstone grinding disc?

Gemstone grinding discs are usually divided into two main types: resin grinding discs and sintered grinding discs. Resin grinding discs are cheaper, suitable for general processing tasks, and have good self-sharpening properties. Sintered grinding discs are more durable and suitable for tasks requiring higher processing pressures and temperatures, but are generally more expensive.
