7.5kw/5.5kw 30000rpm metal cutting spindle motor.
High efficiency: the highest rotating speed is 30000 rpm, the power is 7.5kw/5.5 kw respectively(optional), High speed and fast machining, flexible tool change and stable performance. Installing encoder can realize quasi-stop.
High precision: taper hole runout is less than 0.001, reaching the same level abroad.
Long service life: The most advanced foreign ceramic ball bearings are adopted, and the vacuum dipping treatment of motor wire wrap is unique in the country.
High rigidity: (1) The main shaft has a compact structure and all parts are machined by grinding. (2) The bearing is preloaded with high-load spring, which makes the work vigorous.
