Schmith grinding discs - ideal for metalworking
Metal grinding discs are extremely commonly used accessories not only in the metalworking industry, but also on the construction site. They are designed to remove contaminants from metal workpieces, grind welds, soften sharp edges, remove rust and prepare the surface for further work, such as polishing with a polishing machine. Grinding discs are characterized by high performance, so they can be used intensively for a long time.
Metal grinding discs, like cutting discs, are made of grains of electro-corundum, an abrasive material characterized by high performance and sharpness. Discs can be made of ordinary EDM or ceramic or zirconium EDM, which, due to additives, have better cutting properties. However, regardless of the type of material from which grinding discs are made, their key feature is the grammage of the abrasive grain, which determines the aggressiveness of grinding.
What to look for when choosing metal grinding discs?
The choice of an alumina grinding disc, as with the choice of any other type of grinding disc, should be dictated by the purpose for which it will be used. For this reason, it is important to pay attention to several features and characteristics of grinding discs, which are:
- Disc size - the most popular and common types of grinding discs are those suitable for use with various sizes of angle grinders. They can be 115 mm, 125 mm, 150 mm, 180 mm or 230 mm in size, and have a center hole of 22.23 mm, the standard size assigned to discs for angle grinders.
- Disc thickness - the thickness or height of metal grinding discs is much greater relative to metal cutting discs, this is the parameter by which you can most easily distinguish one type from another. The most common grinding discs are 4 mm, 6 mm, 7 mm, 8 mm or 10 mm high. The thicker the disc, the longer it can be used on the job, but at the expense of its convenience, which is reflected in the increased weight of discs of greater thickness.
- Disc hardness - is denoted by the letters T and E, where T is assigned to hard discs and E to soft discs. Disc hardness is essentially the type of hardness of the abrasive grain. Discs with soft alumina do a better job of grinding hard materials, as they minimize the effect of loose abrasive, thereby preventing the disc from overheating. The opposite is true for grinding soft metals, where a disc with hard alumina will perform better.
Types of discs for grinding metal
Discs for grinding metal is a group of products that includes not only alumina grinding discs, but also other types of grinding wheels, such as:
- Fiber discs - also known as fiber discs or abrasive discs . These are abrasive-coated discs, equipped with a distinctive hole with a cross-cut in the center, which makes them easy to mount in angle grinders. They are designed for preliminary grinding of various surfaces.
- Flapdiscs - also known as flap wheels, are made of flaps of paper or abrasive cloth and equipped with a center hole of 22.23 mm, which allows them to be placed in an angle grinder. Flap discs have several types of corundum grit, distinguished by color, where brown indicates use for metal and wood, blue for stainless steel and red for stainless and acid-resistant steel.
