Having trouble with your band sawing operations? Fix it quickly with our practical tips!

PREMATURE WEAR

• Lower blade speed. Use a finer tooth pitch
• Use proper coolant for the material.
• Keep teeth engaged to prevent blade "polishing".
• Do not allow teeth to rub inside the cut — increase pressure if needed. Use excess coolant if required when cutting mild or non-ferrous metals.
• Ensure teeth are facing the correct direction.

VIBRATION DURING CUTTING

• Adjust blade speed (increase or decrease depending on material and thickness).
• Increase blade tension. Use finer tooth pitch. Increase feed pressure. Clamp workpiece securely.

TOOTH BREAKAGE

• Use finer tooth pitch for thin materials.
• Eliminate vibration by securing the workpiece. Check for blade slippage or incorrect tension. Use proper coolant for soft materials.
• If clogging occurs, switch to a thicker coolant. Reduce feed pressure.
• Use coarser tooth pitch based on workpiece size.

POOR SURFACE FINISH

• Increase cutting speed. Use a finer tooth pitch.
• Reduce feed pressure. Use proper coolant.

PREMATURE BLADE FAILURE

• Blade thickness may be too high for machine wheels or speed. Lower cutting speed.
• Check for wheel edge defects. Reduce feed pressure.
• Lower blade tension. Adjust blade guides.
• Use coolant.

CROWNED OR HOLLOW CUT SURFACES

• Increase blade tension.
• Adjust guide spacing to suit the workpiece width. Use coarser tooth pitch.
• Reduce feed pressure. In case of chip clogging, use coarser tooth pitch and increase coolant
• Adjust pressure or feed rate as needed. Increase blade speed.

POOR CONTACT WITH BACK GUIDE (VERTICAL MACHINES)

• If blade bounces in front of back guide: remove weld burrs from blade back.
• If blade intermittently touches back guide: reweld and realign blade ends.
• Check wheel alignment, especially with more than two wheels. Check for worn or deformed back guides.

BLADE BOWED OR CONCAVE BACK

• Blade is pressing too hard on guides.
• Adjust blade tracking on wheels first, then adjust guides. Convex back = excessive pressure.
• Use coarser pitch for better penetration. Guides may be too far apart for workpiece size.

BLADE WANDERING (TRACKING PROBLEMS)

• Asymmetric or damaged tooth set.
• Misaligned guides — readjust or replace if worn.
• If equipped with cleaning brushes, verify alignment and replace if necessary.
• Excessive feed pressure — reduce feed.

TWISTED BLADE

• Blade warps during cut: reduce feed pressure. Side guides may be too tight?
• Blade may be too wide for the cutting radius. Reduce blade tension if needed?
