Symptoms: A CNC vertical machining center supporting FANUC-0M system often has an overload alarm during processing. The alarm number is 434. The manifestation is that the Z axis motor current is too high, the motor heats, and the alarm disappears after about 40 minutes. Then the alarm disappears. After working for a while, similar alarms appeared again.
Analysis and treatment process: After checking the electrical servo system is not faulty, it is estimated that the load is too heavy to be fixed. In order to distinguish between an electrical fault and a mechanical fault, the Z-axis motor is removed and mechanically disengaged and the fault no longer occurs during operation. It was confirmed that the mechanical screw or the moving part is too tight. Adjust Z-axis screw locknut, the effect is not obvious, and later adjust the Z-axis guide rails, machine load significantly reduced, the failure to eliminate.
Air picks are tools driven by compressed air.The compressed air is distributed into two ends of the cylinder in turn by the tubular distributing valve to make the hammer conduct reciprocating impact movement and impact the tail of the pick, so that the air picks are driven into the rocks or the strata of ores, splitting into pieces.Pneumatic air picks are applied mainly in crushing reinforced concrete buildings, cement, permafrost, icy sheets of layers, soft ores, soft rock, pavement construction. We have five models of pneumatic air picks: G10, G11, G15, G16 and G20, in which G11 and G16 are anti-freezing pneumatic air picks.
