Preventing Saw Blade Fractures
There are several reasons why bandsaw blades fail. Weld breakage is generally thought of as a manufacturer problem. The required length of band is cut from a coil and then welded together at both ends. Most weld centers follow the same procedure in creating bandsaw blades. It is important to assure that the two bands are tightly joined to avoid blade fracture at the weld. Simple adjustments to your bandsaw will put an end to blade problems. Bandsaw operators should be knowledgeable in order to prevent such problems. Common ways for an operator to prevent blade breakage include: Accurately setting …
Issues with Square Cut
A few of the possible causes for a bandsaw machine’s inability to cut square depend on the nature of the problem. Is the bandsaw level and secure? Are the load and discharge conveyors on the same plane as the vise bed? Are the saw guide inserts, backup bearings, and thumbscrews all in good condition? Are the band wheel and wheel bearings in good or bad condition? Is the saw head squarely adjusted to the fixed vise? Does the pivot head show wear? If the saw cut is dished or curved, the cause might be inadequate band tension, excessive feed force, the feed control system may be out of calibration, applying …

Bandsaw Blade Twist
Bandsaw blade twist occurs when the saw blade suddenly changes direction — left or right — while making a cut. The term might not be familiar to some but this is actually a common problem that can crop up during the cutting process. Some common causes of bandsaw blade twist include the saw blade binding in the cut. This occurs when the amount of feed force applied exceeds the required rate. Reduce the feed rate or follow the saw blade manufacturer’s recommended feed rates The wrong blade width is used on radius cuts. Use a narrower blade or refer to the bandsaw’s owner’s manual for recommended blade …
Work Hardening and The 701 Series
Work Hardening and The 701 Series of high performance bandsaw blade that ends at 4-6 TPI. Why does this blade end at 4-6 TPI? The difference between the 3-4 and the 4-6 TPI from 5-8, 6-10, and 10-14 variable tooth pitch is the rake angle on the teeth. For the 3-4 and 4-6 variable tooth pitch, both blades have ten° of positive rake teeth, which means that the tooth angles move forward — in the direction of the cutting action. The 5-8, 6-10, and the 10-14 TPI all have a zero° rake angle on the teeth, which means that the harder the blade …
Measuring Saw Blades Without Cutting
Measuring Saw Blades Without Cutting — Like many items that may have been procured second-hand or a long time ago, the chances of having the owner’s manual that came with the piece is usually slim. If that is the case, then today’s post should offer a bit of help meant to help explain how measuring a bandsaw blade without the need for cutting. For bandsaws that have been in use for awhile, the actual length of that blade can be a tricky number to determine. However, with a little bit of measuring, the number is easier to find than one might think. Here are the steps …
Defining Saw Blade Tooth Sets
Defining Saw Blade Tooth Sets Nomenclature is the study of words and their usage, and jargon is a term used to describe the unique aspects of a profession’s equipment and/or procedure. In the metal sawing industry, this jargon becomes a complex issue of word usage that can often end up overwhelming and exasperating those not familiar with all aspects of the industry’s jargon. It even has the potential to confuse those already in-the-know when the same piece of equipment is referred to by two different forms of that jargon. We say tires when we mean belts, or we will refer to lubricants as coolants interchangeably when …
