Diamond polishing pads are commonly used abrasive tools in polishing and grinding. They are used to process various materials. Diamond polishing pads are divided into polishing pads made of various materials. Metal diamond polishing pads and resin diamond polishing pads are the two main types. They are different in material, structure and application.
I will explain to you what I know about these conveniences so that you can better understand their characteristics and scope of application and how to select them.
Difference in materials
Metal diamond polishing pads, their matrix is mainly composed of metal, such as (copper，bronze, nickel, etc.). The diamond particles are directly embedded in the metal matrix, and the emery particles are firmly fixed on the surface of the diaphragm through a welding process. The metal binder plays a supporting and fixing role for the diamond. At the same time, the stability and durability of the grinding disc are ensured.
The matrix of resin diamond polishing pad is mainly composed of resin (such as epoxy resin, phenolic resin, etc.). Due to the flexibility of the resin bond, it provides the pads with good flexibility and softness
Features and Benefits
The sharpness of metal diamond polishing pad is very high, and their diamond grit is in (30/50/100/200/400). Because the diamond particles are directly fixed on the metal matrix, the metal pads are very sharp.
It also has high stability, so metal pads are more stable during high-speed processing, which is beneficial to improving grinding efficiency and accuracy.
In comparison, the sharpness of resin diamond polishing pad is lower, and their diamond grit is in (50/100/2000/400/800/1500/3000), reaching a fine diamond particle size. Due to the softness of the resin diamond grinding disc, it distributes the pressure on the working surface more evenly, thus producing a smoother and finer surface. And has a long service life.
Application areas
How to Choose the Right Diamond polishing pads
Metal diamond pads are mainly used for grinding materials with higher hardness, such as metal, ceramics, glass, carbide, granite and other hard materials. Suitable for removing uneven materials on the surface of the material
Resin diamond pads are more suitable for fine polishing of stone, rubber, plastic, etc.
For example, when processing stone, it is recommended to use metal diamond pads for rough grinding and fine grinding. Metal pads are highly sharp and can quickly remove material from the stone surface.
If polishing is required, resin diamond pads can be used, which are not easy to scratch the surface and can achieve very high surface finish and flatness.
Some things to note
The correct selection and use of diamond grinding discs can improve processing efficiency and processing quality.
When using diamond grinding discs, you should pay attention to the following matters:
Please choose the type and particle size of the grinding disc correctly.
Use appropriate grinding speed and pressure.
Pay attention to cooling and lubrication.
Clean the grinding powder on the grinding disc regularly to avoid affecting the next use.
There are significant differences in material, structure and application between diamond metal diamond polishing pads and diamond resin diamond polishing pads. Selecting the appropriate abrasive disc depends on the material properties of the workpiece, the processing requirements, and the required processing accuracy and surface quality.
Therefore, when making processing selections, it is necessary to comprehensively consider these factors and select the most suitable type of grinding disc according to the specific situation.
