diamond gang saw manufacturing process

Introduction

Diamond gang saws have become an essential tool when it comes to cutting large stone blocks into slabs, making them suitable for use in various construction applications. Diamond gang saws consist of a set of blades that work concurrently to split the rock blocks into several flat slabs. While this process may seem simple, it relies on a sophisticated manufacturing process that involves several aspects, including substrate selection, diamond blade structure and size, and the choice of bonding material. This article aims to discuss the manufacturing processes involved in making diamond gang saws, and how the different aspects of the manufacturing process contribute to the final product.

Substrate selection

The choice of substrate or base material used in diamond gang saws is critical to the performance of the tool. The most common substrate materials used are steel, brass, bronze, or aluminum, each with specific properties that make them suitable for different applications. For example, steel is a commonly used substrate in diamond gang saws because of its durability and strength, making it suitable for cutting granite and other hard natural stones. On the other hand, brass offers excellent heat dissipation capabilities, making it ideal for cutting soft materials that generate a lot of heat during cutting.

Diamond blade structure and size

The diamond blade structure and size is another important factor to consider when manufacturing diamond gang saws. The blades are typically designed with a specific diamond concentration and size, which determines the cutting performance and blade life. Increasing the diamond concentration in the blade enhances the cutting performance but lowers the blade's life, while decreasing the diamond concentration generally results in a longer blade life but poorer cutting performance. The size of the diamond particles used in the blade also affects the cutting performance by influencing the blade's cutting speed and hardness.

Diamond selection

The choice of diamond used in making diamond gang saws is also critical to the tool's performance. The diamond used should have high thermal conductivity to avoid cracking during cutting, high toughness and wear resistance, and a low level of impurities. Additionally, the size and shape of the diamond particles used should be carefully considered, with the ideal size being between 20-30 microns, while the shape should be round to meet the specifications necessary for diamond gang saws.

Bonding material

The bonding material used in the manufacturing of diamond gang saws is another important factor that influences the performance of the tool. The most common bonding materials used are metallic bonding, which involves fusing the diamond particles onto the substrate using a metallic alloy, and resin bonding, which involves bonding the diamond particles onto the substrate using a thermosetting resin. Each bonding material has its unique characteristics, with metallic bonding being preferred for its durability and stability, while resin bonding is best for cutting applications that require high precision.

Conclusion

Manufacturing diamond gang saws is a sophisticated process that requires careful consideration of various factors, including substrate selection, diamond blade structure, diamond selection, and bonding material. Each of these factors plays a critical role in determining the final product's performance and applicability, with the wrong choice leading to suboptimal results. Therefore, manufacturers of diamond gang saws need to conduct extensive research and development to come up with suitable combinations that deliver the optimal performance for the specific applications.
