The hydraulic cutting unit fails to cut sheets completely with rough edge, burrs and tearing, unable to meet delivery standards.
Main causes: worn and dull cutting blade edge; low adjusted hydraulic pressure; air mixed into hydraulic oil circuit leading to insufficient cutting power.
Solutions: Grind blunt blade edge or replace with new alloy cutter; adjust hydraulic pressure to standard range; lift and lower the oil cylinder repeatedly to exhaust air inside the oil circuit, ensuring powerful cutting and smooth edge without burrs.
