Spindle is a new technology which combines spindle and spindle motor in the field of NC machine tool in recent years. It will push high speed machining to a new era together with linear motor technology and high speed tool technology. The motorized spindle is a set of components which include the motorized spindle itself and its accessories: motorized spindle, high frequency conversion device, oil mist lubrication device, cooling device, built-in encoder, tool changing device.
Spindle fusion technology:
High speed bearing technology: the main shaft usually uses composite ceramic bearings, wear-resistant and heat-resistant, life is several times the traditional bearings; sometimes also use electromagnetic suspension bearings or static pressure bearings, the inner and outer rings do not contact, theoretically unlimited life;
High speed motor technology: the motorized spindle is the product of the fusion of the motor and the spindle. The rotor of the motor is the rotating part of the spindle. The key technology is dynamic balance at high speed.
Lubrication: The lubrication of the main shaft generally adopts timing quantitative oil and gas lubrication; it can also be lubricated by grease, but the corresponding speed should be reduced. The so-called timing, is every certain time interval injection of oil. The so-called quantitative, is through a device called quantitative valve, control the amount of oil per lubricating oil. And oil and gas lubrication, refers to the lubricating oil carried in compressed air, is blown into the ceramic bearing. Oil quantity control is very important, too little, can not play a lubricating effect; too much, in the bearing high speed rotation will be due to oil resistance and heat.
