Principles and precautions for selecting cutting discs

Cutting sheet is widely used in many industries because of its convenient and economical performance.But many people have neglected to make a reasonable choice according to the occasion of their use. So what are the principles of cutting?

1. Good appearance of uniformity and no crack are the basic appearance of the cutting sheet;

2, Excellent packaging and printing anti-counterfeiting bar code is the difference between the original products and counterfeit goods;

3. The lower the static unbalance value of any cutting piece, the better, of course, the greater the production difficulty;

4. The general rule of cutting and polishing is that the amount of iron is less, the grinding wheel is too hard for low wear, the amount of iron is less, the amount of wear is too large is the material is too bad, the internal quality is as little wear as possible, a large amount of iron, at the same time feel good;

5, For carbon steel, alloy steel, cast steel, stainless steel, copper aluminum, glass stone, because their tissue density and heating conditions are not the same, also decided to choose to cut when there is a difference; For glass stone, there are special tools for cutting and polishing glass stone on the market. Copper, aluminum and stainless steel solid materials with lower thickness or zirconium corundum as the substrate for cutting or polishing pieces; For the cutting of carbon steel, stainless steel profiles (non solid) requirements to choose some higher hardness grinding wheel will greatly improve the life; But for solid round steel, forgings and requirements in the hardness of the grinding wheel can not be too high, otherwise it will not move!

In summary, when grinding hard metal, should choose a softer cutting sheet.Because at this time easy blunt, in order to be able to hone in time, so should choose softer.Conversely, when grinding slightly soft materials, sand passivation is relatively slow, should choose a harder, in order to maintain the grinding performance. However, in the grinding of very soft materials, such as non-ferrous metals, because the grinding wheel is easy to be blocked by chips, so should choose a softer grinding wheel.
