PROBLEM:

1. No clearance between body back and flange of the wheels.
2. Worn back guides.

SOLUTION:

1. Adjust wheels.
2. Replace back guides.

PROBLEM:

Body cracks caused by worn back guides. Leading to the back edge of the blade becoming brittle.

SOLUTION:

Replace back guides.

PROBLEM:

Worn or incorrectly adjusted brushes are reducing the life of the saw blade.

SOLUTION:

Adjust brushes regularly and replace when worn.

PROBLEM:

Incorrect alignment causes burrs at the band back edge, followed by microcracks. RESULT: Blade breakage.

SOLUTION:

Adjust wheels. Keep a clearance between band back edge and flange of the wheels. (Recommended clearance: 0.5 to 1.5mm).

PROBLEM:

The constant rubbing along the band saw back edge has induced a brittleness. Microcracks appear. RESULT: Blade breakage.

SOLUTION:

Replace back guides.

PROBLEM:

Too tight or blocked damping rollers may lead to rupture of the body.

SOLUTION:

Reduce the contact pressure so the rollers can be rotated with little effort in passive state. Replace blocked damping rollers.

PROBLEM:

Too strongly adjusted or damaged side guides cause formation of microcracks and blade breakage.

SOLUTION:

Reduce pressure. Clean side guides.

PROBLEM:

The tooth gullet is too small. To much frictional heat is generated. Result: Heavy wear and cut deviation.

SOLUTION:

Select a coarser tooth pitch.

PROBLEM:

The tooth gullet is too small. Chips will overfill the tooth gullet and lift the blade. When the chip clears the gullet, the blade will be forced back into the cutting channel resulting in a shock load on the toot

SOLUTION:

Select a coarser tooth pitch.

PROBLEM:

Teeth have no guide in the cutting channel. Resulting in high tooth loads at the cutting point. RESULT: Fractures and breakages as well as microcracks in the tooth gullet.

SOLUTION:

Use finer tooth pitch.
