Spindle Motor, a new technology that integrates lathe spindle and motor in the field of CNC machine tools.
The spindle is a set of components, which includes the spindle itself and its accessories: spindle, high-frequency frequency converter, oil mist lubricator, cooling device, built-in encoder, tool changer and so on.
This motor and spindle "two in one" form of transmission structure, so that the spindle components from the machine tool transmission system and the overall structure of the relatively independent, and therefore can be made into a "spindle unit", commonly known as the "Electric Spindle" (ElectricSpindle, Motor Spindle), featuring high speed, high precision, low noise, the inner ring with a locking mouth of the structure is more suitable for spray lubrication.
The features are high speed, high precision, low noise, and the structure of inner ring with locking port is more suitable for spray lubrication.
1,This spindle is with built-in three-phase AC asynchronous induction motor, which is controlled by a frequency converter for stepless speed change. With compact structure, low vibration, low vibration and low noise, The spindle can realize high speed, high precision and high stability
The spindle adopts grease lubricated ball bearings, which can be reused indefinitely within the life cycle of the bearings without replacement
3,This spindle uses forced cooling to cool the motor, the coolant flows through the spindle body to take away the heat generated by the high-speed rotation of the spindle, to achieve thermal balance, so that the temperature of the spindle is constant within a certain value. The external cooling device serves to keep the temperature of the coolant constant.
4, The spindle is with air seal structure in the front of the spindle shaft end, which can effectively prevent the damage of external harmful substances on the spindle during its working.
