Many different types of stones vary according to their intended use. Among these, the most commonly used stone models are cut stones. Depending on the current size and design, it can be used in different places.
Three types of metals are used in grinding wheels: AO, ZR and CR.
Aluminum Oxide (AO) It is generally recommended for grinding high tensile strength materials such as stainless steel and tool steels. Still, it can also be used on some aluminum and bronze alloys with high tensile strength. Aluminum oxide is produced in various qualities.
Zirconium Alumina (ZR) It is designed to be used in demanding grinding applications requiring excessive stock removal. The sand in question has been developed with high-tech resin binders.
Chromium (CR); Much harder than standard aluminum oxide, with a very sharp abrasive grit. It is a versatile material recommended for grinding relatively soft metals such as aluminum or cast iron, but it can also be used on tough materials such as cemented carbide.
The grade indicates the relative holding power of the binder that holds the abrasive minerals on the stone.
Soft Grade:
• For hard materials such as hard tool steels and carbides
• For larger contact areas
• For rapid stock removal
Hard Degree:
• For soft materials
• For small or narrow contact points
•For longer stone lifetime
Flap discs are abrasive machines used to sand metal and obtain a smooth surface. This part is attached to the end of the angle grinder. Thanks to the sandpaper-like roughness on the flap disc surface, they help you to get rid of the burrs on the covers.
Flap discs are often used to etch metals. In addition, this disc is also used for sanding marble. When used on metals, they remove burrs and roughness on the surfaces and ensure that the characters are ready for joining. In the same way, they release the protrusions on the surface and provide a smooth surface. Like standard sanders, flap discs have numbers. Choosing the correct number of flap discs for the suitable material and the right job is essential.
