You will need
  • - bench vise;
  • - angle grinder ("grinder");
  • - cutting disc with diamond coating;
  • water;
  • respirator;
  • - rags.
Try to determine is existing magnet breakup. Some types of magnets, for example, powder, can not withstand machining. Magnets of ferrite material under certain conditions be split into independent parts, while maintaining the magnetic properties of the material. Before you start working on cutting the magnet, try as he machinable, nedelev him off the edge.
Prepare tools and materials for the job. You will need an angle grinder ("grinder") and the cutting disc with a hard diamond coating. Such disks are used for the treatment of high-strength metal or pieces of stone.
Check the source magnet cut line. To do this, use a sharp metal object (nail, metalwork Scriber) and a metal ruler. Line markings apply to three or even all four sides of a magnet, if you want to get a smooth cut.
Clamp the magnet into a bench vise to cut the line was clearly visible and the grip does not interfere with the alignment tool. In order not to damage the surface of the magnet, use a strip of soft metal, for example aluminum strip.
Protect face mask or respirator because during processing, the magnetic material will produce a specific dust that can easily get into the respiratory tract. Now you can start cutting the magnet into pieces.
Put the cutting edge of the tool to cut lines and carefully, without effort, start to process the material. Do not hurry, otherwise, cut the line it may turn out uneven. In the course of the work the magnet does not lose its properties prevent overheating of the material. To do this periodically during cutting, stop the process and moisten the treatment site with cold water. After processing, clear the resulting new magnets from abrasive particles by wiping with a clean rag.
