Details

Diamond sanding abrasive belt is a kind of coated abrasive tool, which is superhard material (synthetic diamond) abrasive particles adhesive to the flexible base by the bond.

Applications of Diamond Sanding 

Diamond Sanding

Diamond sanding abrasive belt can be widely used for grinding steel, stone, glass, ceramics, monocrystalline silicon, polysilicon, zirconia, alumina, metal-nonmetallic synthetic materials, cemented carbide, aluminum-magnesium alloy, aluminum beryllium alloy, titanium alloy and etc. hard brittle materials.

Classification of Diamond Sanding Belt
Bond:Diamond sanding abrasive belt is divided into metal nickel plating electroplated bond and resin bond, a resin bond also consists of flexible and hard type.

Pattern:There are many grinding advantages such as sharpness, durable, flexible, dry or wet grinding for diamond sanding abrasive belt with various patterns. Please choose different design patterns according to needs.

Backing Base:The main characteristics of the backing are thickness, softness, temperature resistance, and easy quickly removal. Select the backing base according to the material which will be ground.

Bonded Type and Characteristics Analysis

Electroplated Bond Diamond Abrasive Belt

Electroplated Bond Diamond Abrasive Belt

Diamond particles are bonded on the required coated pattern by nickel plating, which forms a sharp abrasive layer with very strong grinding force.

Resin Bond Diamond Abrasive Belt

Resin Bond Diamond Abrasive Belt

Resin bond divided into flexible and hard resin according to the degree of hardness.

With good softness and flexible coated patterns, the flexible resin can better fit the surface of the workpiece and has better polishing performance. Because the resin is soft, wear is faster, and the temperature resistance is poor, it is not suitable to make coarse grit sized abrasive belt. While the flexible resin sanding abrasive belt must be for wet grinding, which also restricts the application under certain condition.

Thus, compared with the flexible resin, the wear resistance of hard resin is obviously improved, and the temperature resistance is better. Therefore, hard resin diamond sanding abrasive belt can dry grinding to meet the processing requirements of water-proof and oil-proof products. Thicker resin abrasive layers make sanding belt to be various meshes, forming the system application from rough to finish grinding. But hard resin belt is not relatively flexible and suitable for a roller with a larger diameter, especially for thermal spray coating industry grinding.

CBN Abrasive Belt

The hardness of CBN abrasive 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

Features of the CBN Abrasive Belt

*The hardness of CBN abrasive belt is much higher than that of conventional abrasive belt. It is suitable for machining materials with high hardness, high toughness, high strength and low thermal conductivity. Compared with diamond abrasive belt, its metal abrasion rate is 10 times higher than that of diamond abrasive belt.

*CBN abrasives have excellent grinding performance. Because they are sharper than conventional abrasives, when machining difficult-to-machine material, they are not only efficient, but also the workpiece after processing has good shape, high dimensional accuracy, good grinding quality and good surface integrity. The workpiece processed has longer service life and higher reliability.

*CBN abrasive belt features high hardness, high grinding ratio and long service life. Compared with conventional abrasive belt, it can save cost.

*The shape and size of CBN abrasive belt change little in the process of using, especially suitable for machining high precision parts in CNC machining center.

*In the process of machining workpiece, CBN abrasive belt can keep sharp cutting force for a long time, and grinding force is small, and the workpiece processed has high accuracy and high finish, and the power consumption of the lathe can also be controlled.

*The temperature is low in grinding process. The surface quality of the workpiece processed is high, effectively avoiding the workpiece crack and burn.

*Compared with conventional abrasives, there are less dust and reduce environmental pollution and harm to employees for CBN abrasives.

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.
