What Kind Of Magnet Is Used For The Tool Post Magnet?

What kind of magnet is used for the tool post magnet?

The requirement of the tool holder magnet is very simple, that is, it can hold the tool and keep the tool from falling. Knife holders are daily necessities and need to be promoted to seize market share. Vicious price competition is a common method used by merchants. In order to free up profit margins, it is natural to reduce costs on the spare parts of the tool holder.


The NdFeB material is characterized by being hard and brittle. After magnetization, the absorption weight is more than 600 times its own weight, and it is very easy to absorb and bump. And can't use magnets for magnetic separation. In general, there are more bumps, resulting in wear and tear, and the damaged part is oxidized due to loss of coating, resulting in loss of magnetic force. First of all, the tool holder magnet is generally made of strong magnetic neodymium iron boron, which has the characteristics of high suction and high surface magnetism.


NdFeB is easily corroded, and the general coating requirement is galvanized or nickel-plated. Both galvanized and nickel-plated are silver-white metals, but nickel-plated is more shiny and corrosion-resistant, and the cost will be higher. The tool holder magnet is generally built in, so it is natural to choose galvanized in order to reduce costs.


To sum up, anyway, N28, N33, and N35 are all strong magnets, as long as they hold the tool, it will be OK. Naturally, some people choose to take the risk and customize the materials of N28 and N33. The magnetism of N28 and N33 is very strong, but extremely unstable. Demagnetization may begin to appear in two or three months, and it is half a year to be optimistic. Can you imagine that when you are cooking in the kitchen, the knives fall due to lack of suction?

 

Therefore, when choosing a magnet supplier, it is very important to have word of mouth first, and then the delivery date, and the unit price can be negotiated slowly. As the saying goes, you get what you pay for.
