The use of diamond wire saws for cutting marble and granite in quarrying operations is a well-established technology. However, improper use can lead to unnecessary losses, so careful selection of the diamond wire saw is essential.

 

Commonly used diamond wire saws fall into two main categories: spring-type and plastic-encapsulated (rubber) types.

 

① Spring-type: During the sawing process, the springs facilitate the rapid discharge of stone slurry. Therefore, the spring-type diamond wire saw is the preferred choice for cutting marble.

 

Granite is harder, the cutting rate is generally slower, and it does not produce the sticky slurry characteristic of marble; consequently, plastic-encapsulated (rubber) diamond wire saws are selected for cutting granite.

 

② Cutting performance: High cutting speed and efficiency are required.

 

Electroplated diamond wire saws feature exposed, sharp diamonds, resulting in high cutting speeds. Thus, electroplated diamond wire saws are frequently chosen for marble processing.

 

However, while electroplated saws are less expensive than hot-pressed sintered ones, they are less durable and have a shorter lifespan, making them unsuitable for cutting granite. In contrast, hot-pressed sintered diamond wire saws offer a long service life and higher costs but are capable of cutting both marble and granite.
