  • What are the common faults of surface grinders

    2020 12 7 1 The grinding head spindle is locked due to overheating The main reason for this phenomenon is impurities mixed in hydraulic oil For example dust iron powder etc Impurities in the hydraulic oil will block the small oil holes in the bearing bush resulting in part of the hydraulic cavity without hydraulic oil so that the spindle cannot form a symmetrical pressure oil cavity.
