Electrospindle initially used in bearing grinding machine, its higher rotational speed (the current application type up to 300,000r/min) can ensure that the grinding of small holes can also be obtained when a high wheel linear speed, so that the bearing to obtain a high surface roughness and form accuracy. Since April 1931, the German physicist Carl.J.Saloman put forward a high-speed cutting (HighSpeedCutting) theory, with the 20th century eight, nineties tooling technology to obtain progress, high-speed cutting technology to obtain more and more widely used. As a high-speed cutting in the high line speed speed source, the development of high-speed spindle also ushered in the spring.

    The use of electric spindle so that high-speed CNC machine tool spindle drive system eliminates the belt wheel transmission and gear transmission of these mechanical transmission mechanism. The electric spindle is directly driven by the built-in motor, thus reducing the length of the machine tool spindle transmission chain to zero, realizing the spindle "zero transmission". This spindle motor and machine tool spindle "into one" form of transmission structure, so that the spindle components from the machine tool transmission system and the overall structure of the relatively independent, so called "spindle unit" or "built-in spindle unit", commonly known as "spindle unit". Unit", commonly known as "electric spindle" (ElectricSpindle, Motor Spindle).

   The main business of our company is the development and manufacture of electric spindles and their supporting motors.
