The granularity of the abrasive shows about the roughness. The hardness and size of the grinding wheel convey data about milling efficiency.
The functional of snagging wheels
We distinguish snagging wheel in the following types:
- cutting wheels
- grinding wheels
The primary purpose of the cutting wheels is to cut all kinds of metal profiles of iron, steel, and non-ferrous metals. Cutting discs make grooves of different depths in the metal and cut off the armature.
It uses snagging wheel for cleaning, polishing, and grinding of metal surfaces. That is why the thickness of this abrasive circle is greater than the cutting wheel. Using this abrasive device, you can remove fine chips from the material with the help of hard particles are in the grinding wheel.
The Type of tool used
- Abrasive discs for small-sized angle grinders with a power of less than 1500 W
- Abrasive wheels for large angle grinders with a power of up to 2600 W
There are also circles designed for installation of stationary equipment only. Their main differences are external dimensions and optimally rotation speed.
The grit size of Snagging wheels
Grinding wheels are divided by size and type of grinding grain. It is also customary to distinguish the quality of the connection of solid grains in a circle. Today on the shelves of construction stores, you can buy grinding wheels with abrasives from aluminum oxide. Carbon steels, hard alloys, cast iron, and wrought iron, can be ground with such circles. For soft metals (copper, bronze, etc.), stone and rubber; silicon carbide grinding wheels are perfect.
The outer diameter of the Snagging wheels
The width of the circle must correspond to the tool. Rings of different sizes are available – from 80 to 500 mm. But only some of them are suitable for household angle grinders.
The size also matters: the larger the diameter of the circle, the higher the angular velocity, and, the higher the cutting speed of the metal.
The markings placed on the labels of Snagging Wheels
When choosing to snag discs, the user should pay attention to the markings placed on their labels (or right on the circle), with the help of which manufacturers seek to convey the information about products to customers. Pictograms with images of gloves, headphones, and a respirator will remind users of the safety rules when working with snagging wheel.
There are also high-tech snagging wheels in the market, which include ceramic alumina. It produced by gel sintering technology. Grinding wheels based on this material can grind and even cut almost any material. Cutting should buy a disc with a large grain whereas for grinding fine grain size discs are perfect. The smaller the number on the disc marking, the larger the abrasive.
Conclusion: it uses Snagging wheel for stripping metal workpieces and plastic parts, which allows getting a perfectly flat and smooth surface. It belongs to the category of consumables intended for stripping rust, traces of welding, paints, and varnishes, etc.
