Traditional Cylindrical Grinder

Traditional Cylindrical Grinder

Traditional Cylindrical Grinder



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.


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.



The workhead can swivel 120°, variable spindle speed. The spindle can be fixed and runs reversibly, making it ideal for flexible grinding operations for internal and external cylindrical grinding applications.
