How SMART CUT ® Bond Works?
The sharpest and finest quality diamonds or CBN crystals that go into a SMART CUT® Diamond Bond, immediately penetrate into the material, grinding and polishing as they cut.
Diamonds or CBN Crystals are activated only at the exposed layer. As Bond Matrix layer begin to wear out, diamonds in a new Bond Matrix layer are immediately activated, substituting the already used up diamond layer. The SMART CUT® Bond Diamond Bond makes sure every diamond is in the right place and at the right time, working where you need it most.
The newly exposed diamonds don't effect diamonds already working on the material. Unlike many other diamond bonds, diamonds in a SMART CUT® remains sharp and grow sharper with each cut, prolonging product life and consistent performance.
This advanced formulated open diamond bond design insures minimal chipping, fast cut, constant speed of cut, minimal cutting noise, and most important of all, consistent performance.

Relief Design: The relief design means that the blade has a thinner steel core compared to the diamond section. This configuration reduces the amount of material in contact with the cutting surface, minimizing friction and heat generation. As a result, the blade can cut more smoothly and efficiently, reducing wear and extending the blade's lifespan. Steel Core: The core of the blade is made of high-quality steel, providing the necessary strength and rigidity to handle high-load cutting operations. The steel core's thinner profile ensures flexibility and precision, making it ideal for intricate cuts and maintaining tight tolerances. Diamond Section Thickness: The diamond section is thicker than the steel core, providing a robust cutting edge that can handle various materials. The thickness of the diamond section ensures durability and long-lasting performance, even in demanding applications. |
1A1RDiamond Cut Off blade with relief. This blade has steel core. Core thickness is thinner than diamond section thickness. This is the most common diamond blade used in most diamond cut off operations, across wide variety of industries. Description: A flat, continuous rim blade with no slots. Application: Ideal for smooth, precision cutting with minimal chipping. Commonly used in applications requiring a fine finish, such as glass, ceramics, and delicate materials. |
|
The 1A1 wheel shape is one of the most common and straightforward wheel shapes used in grinding and cutting applications. The 1A1 diamond wheel shape is a flat, straight-edged wheel with a concentric circle design, where the abrasive diamond particles are embedded in the perimeter of the wheel.
Shape: The 1A1 wheel shape is flat and has a straight profile with no recesses or flaring. Edge: The edges are straight and perpendicular to the face of the wheel, providing a clear and precise cutting surface. Face: The face of the 1A1 wheel is typically flat and used for grinding or cutting. Diameter and Thickness: The diameter and thickness of the 1A1 wheel can vary based on the specific application requirements. |
1A1The 1A1 diamond blade features no relief, meaning the diamond section and core thickness are identical. This uniformity ensures stability and precision during cutting operations. Application: These blades are especially suited for gang saw applications involving hard brittle materials, glass, optics, and composites. The inherent rigidity of the blade makes it ideal for high load and deep cut depth processing. The cut depth is limited to the height of the diamond section. Kerf Thickness: The width of the cut made by the blade, which matches the core thickness. This consistent thickness ensures stability and precision during cutting. Typical kerf thickness ranges from 0.12 inches (0.3 mm) to 0.125 inches (3.2 mm). Core Thickness: The actual thickness of the blade itself, matching the kerf thickness. This consistency is crucial for maintaining the blade's structural integrity and providing precise cuts. Diamond Depth (Height): The maximum cutting depth is limited to the height of the diamond section on the blade, dictating how deep the blade can cut into a material. Available diamond depths range from 1.58 mm (1/16 inch) to 14 mm (9/16 inch), meaning the blade can only cut as deep as the diamond section extends. |
