Engraving spindle is a kind of high-speed processing spindle, which is widely used in some small and medium-sized engraving machine equipment, mainly can be used for high-speed engraving, drilling, and milling, drilling, etc., involving a wide range of industries. Engraving spindle is the relatively accurate name of the industry, because of the local differences so may not be quite the same, some places referred to as high-speed spindle, some places referred to as engraving machine with spindle, some places called engraving mechanical and electrical spindle and so on are actually the same.
CNC engraving machine is generally equipped with a high performance spindle, in order to play its role. The high-speed rotation of the spindle will produce a lot of heat when it works. If the heat is not dispersed in time, it will have a great impact on the service life of the spindle, and the spindle will be burned seriously. Therefore, water cooled spindle motor or air cooled spindle motor will be selected for heat dissipation treatment.
The greater the hardness of the carving material, the lower speed engraving spindle, this is actually very well understood, the high hardness of the material needs to grind slowly, the speed is too fast but may lead to damage to the tool. The greater the viscosity of the carving material, the higher the speed of the spindle used, which is mainly for some soft metals or artificial materials. Engraving machine tool diameter is also a very important factor to determine the spindle speed. In fact, the diameter of the tool is related to the processing materials and processing lines, the larger the diameter of the tool corresponding to the spindle speed is slower.
