Metal Band Sawing Machine FAQ

1. What are the types of metal sawing machines?

• Bandsaw Machine: Suitable for cutting large cross-section metals with high efficiency and smooth cuts.

• Circular Saw Machine: Ideal for high-speed cutting of small cross-section metals (e.g., pipes, rods).

• Hacksaw Machine: Traditional equipment for simple cutting but with lower efficiency.

• Cold Saw Machine: Low-speed cutting with no thermal deformation, offering high precision.

2. How to choose the right saw blade?

• Material Compatibility:

  • Carbon steel blades: Best for soft metals (aluminum, copper).

  • Bi-metal blades: Versatile, suitable for stainless steel and alloy steel.

  • Carbide-tipped blades: Used for high-hardness materials (e.g., titanium alloys).

• Tooth Pitch (TPI):

  • Coarse teeth (3-6 TPI): For thick materials.

  • Fine teeth (10-24 TPI): For thin-walled pipes or precision cutting.

3. What to do if the cut is skewed or has burrs?

• Causes & Solutions:

  • Insufficient blade tension → Adjust to the recommended tension.

  • Worn blade or incorrect tooth pitch → Replace the blade.

  • Excessive feed rate → Reduce feed pressure.

  • Workpiece not clamped properly → Check fixture stability.

4. Saw machine maintenance tips

• Routine Maintenance:

  • Clean metal chips to prevent clogging.

  • Check hydraulic/oil levels.

  • Lubricate guide rails and bearings regularly.

• Long-term Maintenance:

  • Replace worn belts and gears.

  • Calibrate blade guide alignment.

5. Possible reasons for excessive noise during cutting?

• Loose or uneven blade tension.

• Incorrect blade selection (e.g., too fine tooth pitch).

• Machine instability or vibration from the foundation.

6. How to extend saw blade life?

• Use appropriate cutting fluid (e.g., emulsion to reduce friction).

• Avoid sudden speed changes or overloading.

• “Break in” new blades: Use slower feed rates for the first few cuts.

7. Safety operating guidelines

• Wear protective gloves and goggles.

• Never remove chips by hand (use a brush or tool).

• Adjust the blade or workpiece only when the machine is stopped.

8. Advantages of CNC sawing machines

• Automated cutting with high precision (±0.1mm).

• Programmable for repetitive tasks, ideal for batch production.

• Supports complex angle cuts (e.g., miter cuts, multi-step cutting).

9. Troubleshooting if the saw machine won’t start

1. Check power supply and emergency stop switch.

2. Verify hydraulic/pneumatic system pressure.

3. Inspect motor or controller for faults.
