Several principles for choosing a cutting piece

Cutting sheets are widely used in many industries for their convenience, economy and the like. However, many people have neglected to make reasonable choices of cut pieces according to the occasions they use. So what is the selection principle of the cutting piece?

1. Good uniformity appearance and no cracks are the basic appearance of the cutting piece;

2, excellent packaging and printing anti-counterfeiting barcode is the difference between the factory products and counterfeit goods;

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

4. The general rule of cutting and grinding is that the amount of iron to be removed is small, the wear is low, the grinding wheel is too hard, the amount of iron to be removed is too large, the material is too poor, the inner quality is as little as possible, the amount of iron is reduced, and the hand feels good. ;

5. For carbon steel, alloy steel, cast steel, stainless steel, copper and aluminum, glass stone, because their tissue density and heat status are different, it also determines the difference when choosing the cutting piece; for the glass stone, the market There are special glass stone cutting and polishing tools; copper aluminum and stainless steel solid materials are used for cutting or grinding sheets with lower thickness or zirconium corundum as the base material; hardness is required for cutting carbon steel and stainless steel profiles (non-solid) Higher grinding wheels will greatly improve the life; but for solid round steel and forgings, the grinding wheel should not be too high in hardness, otherwise it will not move!

In summary, when grinding hard metal in grinding, a softer cutting piece should be used. Because it is easy to blunt at this time, in order to be able to self-sufficiency in time, it should be soft. Conversely, when grinding a slightly soft material, the sand passivation is slower and should be chosen to be harder to maintain the grinding performance. However, in the grinding of very soft materials, such as non-ferrous metals, because the grinding wheel is easily blocked by chips, a softer grinding wheel should be used.
