Diamond saw blade use and classification

Diamond is the hardest natural substance we know of, and its hardness makes it ideal for use in cutting tools. A diamond saw blade is one such tool that contains a diamond as a cutting component. It is widely used in industries cutting food, concrete, ceramics, glass, gemstones, and other hard and brittle materials. The continuous advancement of technology has further expanded the application field of diamond saw blades. They are now used in various industries and become an indispensable tool of our civilized society. These blades have exceptional cutting power for precise, efficient cuts. The surface of the blade contains diamond particles, which enhance its durability and strength, allowing it to efficiently cut a variety of materials.

In the construction industry, diamond saw blades are commonly used for cutting concrete and other construction materials. They are able to make clean, accurate cuts, ensuring a seamless construction process and enhancing the overall stability of the structure. In jewelry making, diamond saw blades are essential for cutting gemstones, enabling artisans to transform raw materials into beautiful jewelry creations. In addition, diamond saw blades have found their place in the food processing industry. Their precision cuts allow for precise slicing and preparation of food, increasing efficiency and consistency in commercial kitchens. Additionally, these blades are used to cut technical ceramics used in advanced engineering projects where precision and durability are critical.

With the continuous advancement of technology, we can expect the application fields of diamond saw blades to be further expanded and improved. Its superior cutting ability and versatility make it an indispensable tool in various industries. However, it is important to ensure proper safety measures are taken when using these tools, as well as regular maintenance and adherence to usage guidelines to maximize their performance and longevity.

Diamond saw blades can be classified according to the manufacturing method and sawtooth shape.

Manufacturing method:

a. Sintered Type: These diamond saw blades are manufactured using a powder metallurgy process. They are further divided into: Hot Press Sintering: In this method, the diamond tip is sintered under high pressure and temperature, which creates a strong bond between the diamond and the substrate. Cold Press Sintering: Here, diamond blocks are pressed together using a low-temperature sintering process, creating a softer bond.

b. Welded Type: These blades have a diamond tip welded to the metal core. They are suitable for heavy-duty cutting applications and offer good stability and durability.

c. Electroplating Type: In this method, a thin layer of diamond particles is electroplated onto the surface of the metal core of the blade, creating an extremely sharp cutting edge. These blades are especially effective for cutting brittle materials such as glass, ceramics, and porcelain.

Zigzag shape:

a. Continuous Edge Saw Blades: These blades have a continuous edge with diamonds distributed along the edge. They provide a smooth and precise cut, making them suitable for cutting soft and brittle materials.

b. Segment blades: These blades have a segmented edge consisting of individual segments separated by grooves. They provide efficient cutting performance and are commonly used for cutting hard and dense materials such as granite and concrete.

c. Turbo Saw Blades: These blades have a serrated or turbo edge design with small ridges. They provide faster cutting speeds and can effectively cut through a variety of materials including concrete, stone, and masonry.

Understanding the different types of diamond saw blades can help users choose the one that best suits their specific cutting needs and materials.

Continuous-edge saw blades made by sintering are commonly used for trimming or cutting glass and ceramic materials. Its continuous edge evenly distributes diamonds along the rim for a smooth, precise cut without excessive chipping or cracking. On the other hand, welded saw blades are often preferred when machining construction materials such as stone. These blades have diamond tips welded to a metal core, providing exceptional strength and durability for cutting dense materials. Welded saw blades are suitable for heavy-duty applications and can withstand the rigors of cutting stone. It is worth noting that the shape of the saw blade can be changed according to the specific processing requirements. For cutting boards, a serrated saw blade can be used. These blades feature serrated or serrated edges to help prevent binding and ensure efficient cutting. The gaps created by the serrations allow for easier chip removal during cutting, resulting in a smooth cut across the board. Overall, the choice of blade type and shape depends on the material being cut, the quality of cut desired, and the specific machining techniques involved.

Electroplated diamond blades or wire saws are often preferred over sintered blades when machining gemstones. Electroplated diamond saw blades have thinner thicknesses and higher mechanical precision, making them suitable for cutting precious gemstones without unnecessary damage. On the other hand, sintered saw blades tend to be thicker in thickness, which may not be suitable for cutting precious stones. Instead, they are often used to cut relatively inexpensive gemstones or other materials where precision is less important. Choosing a continuous-edge saw blade is very important for gemstone cutting as it provides a smooth and even cutting action which reduces the risk of chipping or cracking the gemstone during the cutting process. In addition to electroplated diamond saw blades, wire saws are also commonly used for cutting gemstones. A jigsaw consists of a thin wire with diamond beads or segments attached to it, allowing precise and delicate cutting of gemstones with minimal loss of material. Given the value and delicacy of gemstones, choosing the proper saw blade and shape is critical to ensure precise cuts while minimizing the risk of damage.
