Automatic tool change spindle is a new technology that integrates machine tool spindle and spindle motor in the field of CNC machine tools in recent years. Together with linear motor technology and high-speed tool technology, it will push high-speed machining to a new era. The electric spindle is a set of components, including the electric spindle itself and its accessories: electric spindle, high-frequency inverter, oil mist lubricator, a cooling device, built-in encoder, tool changer.
Automatic tool change spindle technology: high-speed bearing technology, electric spindle usually uses composite ceramic bearings, wear-resistant and heat-resistant, life is several times that of traditional bearings; sometimes also uses electromagnetic suspension bearings or static pressure bearings, the inner and outer rings are not in contact, theory Unlimited life
The automatic tool change spindle motor is the product of the motor and the main shaft. The rotor of the motor is the rotating part of the main shaft. In theory, the spindle motor can be regarded as a high-speed motor. The key technology is dynamic balancing at high speeds. Lubrication: Lubrication of electric spindles is generally based on timed quantitative oil and gas lubrication. Grease lubrication is also possible, but the corresponding speed is compromised. The so-called timing is to inject oil at regular intervals. The so-called quantification is to precisely control the amount of oil per lubricant through a device called a dosing valve. Oil and gas lubrication means that the lubricating oil is blown into the ceramic bearing under the carrying of compressed air. Oil quantity control is very important, too little, and does not provide lubrication; too much, when the bearing rotates at high speed, it will heat up due to oil resistance.
