What is a motorized spindle

Motorized spindle is appeared in recent years in the field of nc machine tool spindle and the spindle

motor with new technology,it with the linear motor technology,high speed cutting tool technology,it

will put into a new era in high speed machining.Motorized spindle is a set of components,it includes

motorized spindle itself and acmotortrading.blogspot.com its accessories: motorized spindle,high frequency inverter device,oil mist lubrication,cooling device,the built-in encoder,changing tool device. The fusion electric spindle technology: High-speed bearing technology: electric spindle usually adopt composite ceramic bearings,wear-resistant heat-resistant,life expectancy is a traditional bearing several times;Sometimes also by electric or magnetic levitating bearing static pressure bearing,inside and outside the circle does not contact,theoretically infinite life;Technology: high speed motor motorized spindle is the product of motor and spindle fuses in together,the rotor of the motor is the rotation of the spindle parts,theoretically the motorized spindle can be regarded as a high speed motor.

Key technology is under the high speed dynamic balance;Lubrication: motorized spindle quantity and lubricating timing commonly used lubricating oil and gas;Also can use grease,but the corresponding rate to discount.The so-called timing,is every certain time interval note oil at a time.The so-called quantitative,is through a device called proportional valve,precise control of lubricant oil at a time.And oil and gas lubrication,refers to the lubricating oil in the compressed air to carry,was blown into the ceramic pumps bearing.Oil control is important,too little,no lubrication;Too much,when bearing at high speed for oil and heat resistance.Cooling device: as soon as possible in order to speed motorized spindle heat dissipation,usually on the walls of the motorized spindle with circulation cooling agent,the effect of cooling device is to keep the temperature of the coolant. Built-in pulse generator rotor and stator encoder: rigid tapping screw,in order to realize the automatic tool change and motorized spindle built-in pulse encoder,in order to realize the accurate phase Angle control and feed.
