Resin bond diamond tools

In addition to the tough quartz crystal, the resin binder has a tendency to burn polishing pads not specifically designed for engineered stone. Special high-heat tolerant resins need to be used to avoid marking the surface.

Concrete is characterized as a very abrasive material that can vary widely in hardness depending on the local aggregate used. Typically resin bond tools designed for concrete are run dry and require a high-heat resistance.

In addition, they need to be of a higher density to withstand the weight of a concrete machine that can weigh up to 10 times more than a marble machine. Concrete pads also run on planetary machine heads, which means that they rotate many times more than a stone resin pad. Diamond resin bonded pads have greatly evolved over the years as new applications, new materials and new machines come on to the market. While it may appear on the surface that all resin polishing pads are created equal, it is certainly not the case.

Understanding how these products are made and what constitutes a high-performance product can mean all the difference.

In the next installment of The Basics, we will discuss the sintered bond. We share valuable tooltips and unique ways other professionals are using our tools.

The Mechanics The bond serves two important functions.

Resin diamond grinding wheel is used for finish grinding tungsten carbide tools and can obtain high finish of the workpiece. The bond can be evenly distributed on the surface of abrasives, and hold abrasive grains firmly in the resin bond diamond grinding wheel.

And it can be firmly bonded to the matrix. It can make the abrasives do not fall off easily in the early, and avoid the separation of the bond and the matrix to ensure product safety. Resin bond has elasticity and brittleness, so it has good self-sharpening and not block, but poor wear resistance. Therefore, resin bond diamond grinding wheel should have both high grinding efficiency and high wear resistance under the condition of ensuring the requirement of surface roughness.

The bond formula is very important for the wheel. Resin bond diamond grinding wheel with both grinding efficiency and wear resistance can meet the requirements of processing and reduce the cost.

If the heat resistance of the resin bond is poor, the grinding wheel will not bear high temperature and consume quickly and make the wheel burns and cracks because of the high grinding heat.

Therefore, should choose the bond with good heat resistance and add appropriate fillers to improve the heat resistance for resin bond diamond grinding wheel. At the same time, wet grinding with coolant is used to improve the durability of the grinding wheel. If dry grinding, the feed amount is as small as possible to improve the durability. The strength of bond directly affects the grinding efficiency, consumption, workpiece quality and safety performance of grinding wheel.

If the forming density of abrasives is low and the porosity of abrasive is high, and the bond strength is low. Selection of the abrasives of resin bond diamond grinding wheel:. There are the detailed classification of diamond abrasives in the world and China.

Among them, low quality diamond abrasives or diamond abrasives with high self-sharpening and. RVD type diamond abrasive is widely used in resin bond diamond grinding wheels in China. Its grains are mostly needle-like, irregular crystal shape, low strength, high brittleness, rough surface but sharp grinding. It has good bonding with the resin bond. In recent years, polycrystalline CSD diamond abrasives have been used in resin bond diamond grinding wheel, and significantly improved the sharpness.

A high rate of removal is achieved with these floors, but with higher tool wear. Usually refers to steel trowelled floors or certain types of cement. This includes granite. Diamond Xpress Series Diamond Xpress is a grinding system for marble, terrazzo and other similar types of floors. Thanks to advanced diamond and composite technology, the system requires no water.

Our FP-series is an excellent polishing tool that is very appreciated for its outstanding performance in creating a high gloss. Our REP-series is a grinding and polishing tool specifically developed for wet processing of natural stone such as marble, terrazzo and limestone. New Super Resin tools with extended life.
