Cylindrical Grinder
Hydraulic Universal Cylindrical Grinder
Characteristics :
PRECISION, RIGID SPINDLE
The grinding wheel spindle is supported by two special hydrodynamic bearings on the ends with five-point support, providing maximum rigidity and stability of spindle running. In case insufficient lubrication oil occurs, the spindle stops automatically to avoid wearing on the spindle and bearings.
SPECIAL VIBRATION ABSORBING DESIGN
The forced lubrication system of the grinding wheel spindle features vibration absorbing function. The oil film pressure, created by the hydrodynamic bearings, automatically absorbs vibration according to the current working condition.
