When band saw blades are over-used, they may begin to experience back cracking ? a serious issue that can damage your blade permanently. This issue can be caused by many problems ranging from a wide variety of issues we will cover in this video. Looking out for these fourteen common issues, you can help prevent band saw blades backs from cracking.
One of the main problems that causes saw blade back cracks is when you have your machine?s guide arms spread to far apart, so be sure to keep them properly spread. Always make sure the guide to wheel alignment is correct and that the guides are not too tight. If the top guide is missing, then back cracking is a definite risk to your operation.
If you observe the band saw blade rubbing on the wheel flange, than that can be a sign that back cracks had occurred. Making sure your top guide doesn?t have a notch on it can help prevent back crack. Additionally, if the bend of the saw is too straight than back crack may occur.
Before starting up the saw make sure your speed settings are set correctly and always make sure the saw is not run for too long. Make sure the feed rate is set correctly and the pressure isn?t too high. And always ensure that the saw has the proper amount of tension.
