Diamond CBN Sanding Belts
Flexible Diamond Sanding Belts

HANS Flexible Diamond Abrasive Tools was developed by our engineers to combine the long life and aggressive cutting of diamonds with Nonmetallic cloth and strength backing materials with strength and flexibility. This makes it easy to polish and polish various hard materials such as natural and synthetic stones, construction, composites, superhard coatings, ceramics, glass, operations, metallographic and other flat grinding, Fabric, hardware and other hardmetals in a economically way , we also have alternatives to electroplated flexible patterns that are particularly effective when used as discs and belts for quick removal applications.Diamond abrasive sanding belts in all specifications and dimensions for special applications like centre less grinding of molybdenum heating elements.Flexible diamond abrasive belts for special applications such as center less grinding molybdenum heating elements.

The hardness of CBN Diamond Abrasive Sanding Belt is lower than that of diamond abrasive belt (CBN: 7000-9000; diamond: 8000-10000). But the thermal stability of CBN abrasive belt is much higher than that of diamond abrasive belt, especially when machining iron group metal elements, it has good chemical inertia (diamond abrasive in high temperature during grinding iron group elements makes diamond carbonize easily), and it is not easy to bond.

The CBN abrasive belts have a special patented support material, called aramid fibres. Aramid fibres (also known under the brand name, kevlar) are characterized by their high strength, a very high elongation and a high capacity to dampen vibrations. The support material is applied with a formfitting copper layer. With a nickel base alloy, the CBN crystals are bonded to the abrasive belt galvanically, strewn in a regular intermittent pattern or with no spacing, covering the entire surface (see fig.s).

Applications of CBN abrasive belt

CBN abrasive belt is used to machine containing iron elements hard-to-process materials such as iron and steel, iron alloy, etc. Especially for the surface grinding and polishing of high hardness steel such as high carbon steel, alloy steel and hardened steel, and for the places requiring automatic control, precision and ultra-precision grinding and polishing.

Examples of CBN abrasive belt

Application in precision bearing grinding technology

The abrasive belt is often used for grinding and polishing the surface of precision bearing after forming. But the requirements of shape accuracy and surface finish of finished products are very high. If use conventional abrasive belt, it has poor surface shape retention, and the abrasive passivates easily, and then the chips heat easily, and it has low machining efficiency. While, the abrasive belt has short service life and is needed to replace frequently, so the operator’s technical level is required to be higher.

If use CBN abrasive belt, the abrasive has good shape retention and long service life. It reduces the frequent for replacing belt, and greatly improves the production efficiency.

Applications in CNC abrasive belt grinder

CNC abrasive belt grinder can be used to grind complex curved surface such as all kinds of automotive machine blades and aero-engine blades, as well as to grind and polish propellers, impellers etc. parts.  Conventional abrasive belt has been used for CNC abrasive belt grinder. But it is needed to replace the belt frequently, and greatly reduce the efficiency for CNC grinder. Use CBN abrasive belt, it not only improves the machining efficiency, but also improve the machining quality of the workpiece and reduce the labor cost.
