About products
The high speed spindle is drived by a matching frequency converter. You can equit the converter by youself, but you must pay special attention to set it before use. Of course, if you need, we will do these for you.
The spindle motor adopts Germany/Japanese imported bearing which can make it use for three times longer useful time than ordinary spindle motor. In extremely high speed working environment, ordinary bearing can not ensure this high rotate speed for using for long time. Our Germany/Japanese imported bearing can make spindle motor three times longer useful time than ordinary spindle motor.
