Turret magnet requirements are simple, is able to suck the tool, the tool does not fall.

But reality! Turret is a daily necessities, need to promote and seize market share. Vicious price competition is commonly used by businesses. In order to make room for profit, naturally knife in the spare parts on the knife.

The inside of the magnet can be learned. NdFeB material is characterized by hard and brittle, after magnetizing gravity is more than 600 times its own weight, easy to pull the bump. And can not use the magnet for magnetic separation. Bump more in general, resulting in wear and tear, loss due to loss of part of the coating, is oxidized, resulting in loss of magnetic power. First of all, the turret magnet is generally used NdFeB, the magnetism is always strong magnetism, the original high suction, high magnetism.

Therefore, NdFeB easily corroded, the general coating requirements are either galvanized or nickel plating. Galvanized and nickel plated are metallic silver, but nickel brighter and corrosion resistant, while the cost will be higher. The tool holder magnets are generally built-in, so naturally choose to reduce the cost of galvanized. Understandable

In summary, anyway, N28, N33, N35 are strong magnetic, as long as the tool sucked OK. Some people choose to take the risk of natural custom N28, N33 material. As a magnet in the field of magnetic constant material factory, it is necessary to tell you. N28, N33 table magnet is very strong, but very unstable. Perhaps two months, three months began to demagnetization, optimistic that is half a year. Can you imagine that when you cook in the kitchen, can the cutter fall off?

So, choose the magnet supplier, the preferred word of mouth is very important, and then is the delivery, the price that can be slowly discussed. Or that sentence, penny goods.
