FAQ Related To Slitting Machine
What slitting accuracy can you achieve?
A
Our slitting machines achieve accuracy of ±0.1 mm with clean, burr-free edges — suitable for a wide range of materials from paper and non-woven to films and aluminum foil.
What should I do if slitting edges have burrs?
A
Possible causes include worn blades, incorrect blade angles, or unstable material tension. Regular blade sharpness checks, optimized tension control, and ensuring the material enters the slitting unit flat and wrinkle-free are recommended.
Can your equipment handle specialty materials like metallic card?
A
Yes. Our high-precision double-helix slitting machine for metallic card is specifically designed for high-value materials, delivering ultra-precision slitting to meet the most demanding customer requirements.
What if the machine has excessive noise or vibration?
A
Check blade mounting, bearing wear, and lubrication of transmission components. Our intelligent monitoring system provides early warning of bearing faults to prevent unexpected issues.
