The electric spindle is a new technology that has emerged in the field of CNC machine tools, integrating the machine tool spindle with the spindle motor. The spindle is a set of components, which includes the electric spindle itself and its accessories: the electric spindle, high-frequency frequency conversion device, oil mist lubricator, cooling device, built-in encoder, tool changer, etc.
The electric spindle has the advantages of compact structure, light weight, small inertia, low noise, fast response, high speed, high power, simplified machine tool design, easy to achieve spindle positioning, and is an ideal structure in high-speed spindle units. The electric spindle bearing adopts high-speed bearing technology, which is wear-resistant and heat-resistant, and its life is several times that of traditional bearings.
