BANDSAW MACHINE INSPECTION GUIDE

Items checked / procedure:

Machine Inspection

1 - IDLER & DRIVE WHEELS

Inspect for flat spots on the wheel surfacesRock wheels side to side for bearing play

Problems Caused

Band breakage, blade slip

Items checked / procedure:

Machine Inspection

2 - Guides

Disassemble guides check for cracks and or chips. Carbide guide surface should be higher than surface of the steel holder. Look for excessive wear on the corners of the carbides.

Bearing type guides should be checked for looseness between the center shaft or post and outer bearing surface. Make sure the bearings turn freely.

Problems Caused

Band breakage, crooked cuts, blade vibration.

Tight roller guides will pull the blade off of the idler wheel. Blade should slip freely between guide rollers.

Machine Inspection

3-Guide Arm Alignment

Remove blade from the blade guides, place the blade against the wheel flanges or center the blade on the wheels. The center of the blade should line up with the center of the guide.

Problems Caused

Blade breakage or cracking. Scoring of the bladebacking and crooked cutting. CAUTION: Do not perform a guide arm alignment. Report this problem only. Special training is needed to perform this task.

Items checked / procedure:

Machine Inspection

4 - Blade Tracking

Inspect the band position on the band wheels, the blade must not ride against the wheel flange. The blade should be positioned so that the largest portion of the blade body is supported by the wheel surface.

Problems Caused

Blade breakage and or cracking. Crooked cutting, caused by set damage or blade twist. Wheel damage of flange wear.

Items checked / procedure:

Machine Inspection

5 - Blade Tension

Measure tension with tension meter and record. Proper tension for bimetal blade should be between 190 and 210 N/ mm^2.

Problems Caused

Blade breakage, crooked cutting, vibration and slippage between the band and the wheel.
