Quick Troubleshooting for Common CNC Shearing Machine Malfunctions
Minor daily faults of CNC shearing machines can be resolved rapidly on-site.
- Excessive cutting burrs: Incorrect blade clearance or worn cutting edges – readjust clearance or regrind blades.
- Inaccurate backgauge dimensions: Insufficient lead screw lubrication or loose encoder – apply grease and recalibrate origin points.
- Unmoving tool holder: Insufficient hydraulic oil or clogged solenoid valves – top up oil and clean valve assemblies.
- Lost system parameters: Dead CNC backup battery – replace battery while power is on.
- Twisted cut sheets: Swing beam models unsuitable for thick plates – switch to guillotine shears. For major faults such as hydraulic leakage or frame deformation, call the manufacturer’s national 400 hotline directly; service outlets across 28 cities provide on-site maintenance within 24 hours.
