The main abrasive of the polishing pad is diamond-based, and then combined with composite materials to produce and manufacture flexible processing tools. So what is the performance of the polishing pad, whether it is easy to use or not, how do we choose a custom polishing pad manufacturer? Let’s take a look together.
Due to the irregular shape of the diamond material, there are many concave angles and rough surfaces, the resin bond has a stronger holding force on the abrasive material than ordinary diamond, so under the same grinding parameters, the self-sharpening diamond polishing pad and ordinary diamond grinding wheel In comparison, the grinding ratio is increased by more than 60%. And since the interior of the self-sharpening diamond abrasive is embedded particles composed of many single sub-crystal grains, under the action of stress, only small irregular fragments collapse, leaving many on the surface of each particle. The new small cutting edge, so the surface roughness value of the processed workpiece is lower.
At present, about 60% of abrasive grade diamonds in the world are used to produce resin bond grinding wheels. However, because the commonly used treatment methods do not greatly improve the inertness of the diamond polishing pad surface, the resin does not have good wettability to the diamond, and it is more difficult to form a chemical bond between the bond and the diamond. The bond’s holding force on the diamond is mainly mechanical Interlocking force, so in the resin diamond grinding wheels produced a few days ago, the resin bond’s ability to hold diamonds is not very strong. If we want to improve this situation, we should devote ourselves to improving the resin bond’s mechanical engagement force for abrasives.
According to reports from foreign grinding materials, after grinding PI8 (a foreign cemented carbide grade) products with ordinary diamond resin abrasive tools, about 70% of the abrasives fall off before they are fully functional. Although the use of diamond surface treatment methods (such as diamond polishing pad surface coating, surface plating, etc.) can improve the ability of the resin bond to hold the abrasive, but due to the complex production process and high production cost, the grinding wheel is self-sharpening The performance is also poor, which limits its application to a certain extent.
Due to the wide range of applications and fields of polishing pads, the current use of polishing pads is gradually extending, but what kind of manufacturer do you need to choose for bulk polishing pad customization? At the same time, the unit price of polishing pads is not low, only selected manufacturers must Can guarantee the final polishing pad customization effect, let’s take a look at what kind of polishing pad customization manufacturer to choose?
1. Quality first
Before choosing a polishing pad custom manufacturer, you need to know the manufacturer in advance, mainly to understand its reputation, product quality, and customer evaluation. If the manufacturer has had conflicts with multiple cooperative customers or the quality of the final customized polishing pad submitted If the standard is not up to standard, there is no customer willing to cooperate with such a manufacturer, so quality is the first.
2. Whether there is first-class production equipment
How does the manufacturer’s production workshop directly affect the quality of polishing pad customization? Some manufacturers have advanced production equipment and testing instruments, and when customizing polishing pads, they have strict requirements on the production line in accordance with international advanced standards. Choose such manufacturers to produce The quality of the polishing pad can be more recognized.
3. Choose manufacturers with good market reputation
It is a wise choice to choose what kind of cooperating manufacturer. Many companies know it well, and generally choose cooperating manufacturers with good market reputation and high industry evaluation.
The above is the relevant introduction on how to choose a custom polishing pad manufacturer. Only a professional manufacturer can ensure the quality of the product.
