Vertical lathe bench during use, due to various reasons often leads to the upper and lower guide surface research injury, resulting in hydraulic instability, there is no float and oil overheating phenomena, machine can not function properly. Large vertical flat rail cars are generally circular, once the research will result in injury, damage to the entire contact surface, not timely repair the machine will directly affect the accuracy of the workpiece geometry errors. In production practice, we solve the problem injury research summed up an effective repair solutions. Double column vertical lathe table inlaid with zinc, aluminum, steel wear plate rail, and rail access between (0.2-0.4MPA) Pressure to improve rail carrying capacity. Table spindle is equipped with a one-way thrust ball bearings and a double row cylindrical roller bearings, to ensure that the spindle rotation accuracy. Rigorous casting artificial aging and VSR to ensure that the double column vertical lathe machine tool rigidity and stability. The use of advanced ultra-quenching process, the double column vertical lathe machine last longer. Double Column Vertical Lathe workbench can use horizontal shaft 16 speed, but also select the frequency conversion stepless speed regulation, so can use AC 18 knife feed speed, but also to select the variable speed feed. Special requirements can be installed according to the number of display devices.
