How to Deal with Cracking of Horizontal Band Saw Blade

There are basically the following points for saw blade cracking of woodworking band saw machine:

First, the saw blade quality is not good, now many manufacturers cut corners, saw blade quality is seriously unqualified. 

Second, the saw blade does not match the saw machine, and the saw blade is too thick. 

Three, bearing damage, performance for running noise, saw machine jitter, sometimes even run. 

Four, the saw blade is too long, the saw blade fatigue, sawtooth passivation, under the impact of wood, tearing friction, make the saw blade cracking. 

Five. Excessive calendering of the saw blade causes the saw blade to lose its proper elasticity, or the round or bent saw blade exceeds the standard, resulting in cracking. 

Six, saw blade back is not neat, running back and forth, make the stress part cracking. 

Seven, the lack of cooling water, make the saw blade in the work can't effectively cooling lubrication, and fever fatigue, lead to cracking.

Resolution:

1. Loose saw blade 

2. Change thinner saw blade 

3. find a professional roller saw blade (not professional pressure saw is not straight, remember to random pressure) 

4. find a professional lathe wheel (or change bearings)

What if the saw blade opens its mouth?

If the small opening is less than 2CM, stop it with the small sample punching eye, then stop it with force. both sides should be punched, then gently hit it with the small hammer head, and stop it with the small sample punching eye as early as possible (cut off the head of the hole)

For gas welding larger than 2CM, acetylene must be used instead of gas. Gas welding is easy to open again. Pay attention to flattening, three-part welding and seven-part repair, and finally flattening with wide setback.
