Slim oil pipe, many elbows and no fixing are easy to cause pipe shaking when oil flow rate is high.Unbalanced rotating parts of electric motor and hydraulic pump, poor alignment during installation or loose coupling can generate vibration and noise.

Solution: It is suggested to separate the long oil pipe from the wall of the machine tool and install support pipe clamp properly.Adjust installation accuracy of motor and hydraulic pump;Reinstall the coupling to ensure that the coaxiality is less than 0.1MM etc.

In addition to routine maintenance, when the ultrafine vertical mill encounters abnormal phenomena in operation, check the fault parts and causes one by one and take corresponding measures in time, so as to avoid greater losses.
