The machine spindles are the important parts of the machine tools, which traditionally driven by the gearings. The electrical spindles are the shortened name of embedded motor spindles, the main property of which is to out the motor inside the spindle, and to run by driving power. Thus to fulfill the motor and spindle compounding.
Characteristics:
Tight structure, high mechanical efficiency, low noise, low vibration, high precision.
Stable running, weak impaction, prolonging bearing life of the spindles.
High speed,high dynamic and static precision, high stability.
The step less variable speed in the rang of the rated running speed is available to suit the request of various conditions and loads.
Driving control skill makes accurate stop, accurate position and accurate speed suitable for the request of processing center and other numerical control machine tools.
Upon the above characteristics, the electric spindles play the important role in improving the production efficiency and promoting the related industry development. Up to now, we have developed 8groups'series,200 variaties of electric spindles with rated speed from 5,000r/min to 150,000,r/min,high speed precision rolling bearing and air static pressure bearing used as its support ,the grease, oil mist, oil gas etc. for its lubrication, two kinds of output of constant torque & constant power.
