Bandsaw Blade Terminology

Bandsaw Blade and Sawing Terminology
Beam Strength is the result of a combination of a blades hardness, thickness and width. A wider blade provides greater Beam Strength which usually produces straighter and smoother cuts. However, never use a blade wider than that specified by the saw builder.
Cutting Edge is the toothed edge of the blade from the points of the teeth to the base of the gullets. The rest of the blade is considered the back.
Gullet is the valley from the tip of one tooth to the tip of the next tooth. It is designed to carry the chip from the kerf.
Kerf is the cut in the material being sawed. The width of the kerf is determined by the thickness of the blade plus the set of the teeth.
Set that is given saw blades is actually the tilt or angle given to the teeth of the blade which provides clearance in the cut. The overall set to right and left is another factor in determining the width of the kerf.
Tooth Pitch is always measured in the number of teeth per inch---from tip of tooth to tip of tooth. Variable Tooth blades are indicated by two numbers since the tooth pitch and the gullet depth varies.
Tooth Types are determined by tooth shape. Examples are Regular, Hook, Skip, and Variable Tooth. Tooth types are designed to do different kinds of sawing. It is essential to match the blade to the job.

Cutting tips that lead to better welds

Practical Welding Today May/June 2013

For performing structural cuts with a band saw, a few simple tips will help in your quest to make straight cuts, which can ultimately lead to better welds.

When band saw cutting I-beam, square, and round tubing, straight cuts are crucial to preparing the part properly for welding. Parts with crooked cuts make welding difficult, to say the least, and as a result, welders often must use a filler or additional welding wire to fill the gap left by the uneven edge. In more severe cases, the parts with uneven cuts may have to be recut or scrapped altogether, which is both costly and time-consuming.
If you are performing structural cuts with a band saw, consider these tips to help ensure that edges are straight and that welders can join parts easily and efficiently. Keep in mind the importance of routine maintenance on the band saw machine. If a machine has problems with its feed system or its variable-speed system, it will negatively affect the life of the band saw blade.
Know the Sawing Parameters

The best way to ensure the cuts you make will be straight is to set your sawing parameters correctly. Set the machine to the correct blade speed and cut rate for the material being cut. As a rule, slow the blade for tough material and increase speed for softer material.

Also, check to make sure the conveyor rollers that hold the material are aligned properly. Rollers that are out of alignment can lead to crooked cuts.
Set the Tension Properly

Use a gauge to measure and set the tension on the blade in the band saw machine. Most band saws work best with the blade tension set to a minimum of 25,000 PSI or a maximum of 32,000 PSI. Anything less than 25,000 PSI leads to poor beam strength, band fatigue, or crooked cuts. Tensions set to 32,000 PSI or more can break the band, crack the gullets, or wear out the machine bearings.
Cut From the Back of the Weld Seam

For applications that involve cutting through a weld seam on tubing, it is easier and more efficient for the band saw blade to enter the material from the back of the weld seam. Cutting directly into the weld seam serves as a shock point to the blade teeth and often results in shorter blade life or teeth strippage.
Secure the Bundles

When band sawing bundles of material, it is best to strap down the entire bundle or tack weld the ends of the bundle to prevent any pieces from moving. If the individual pieces vibrate or move during the cutting process, there is a possibility that the teeth will strip.
Use Proper Lubrication

The proper amount of cutting lubricant, also known as coolant, will help extend blade life. Band saws use a flood-coolant or a mist system to lubricate the blade. Not only does lubrication help maximize blade life, it also helps minimize the buildup of metal chips that result when the material is cut. Coolant should wash over the blade as it enters and exits the cut. Although the coolant is recirculated and used continuously throughout the cutting process, be sure to replace water that evaporates from the mixed solution.
Breakin New Blades

Be sure to break in new band saw blades before you ramp them up to full-speed cutting. This practice will hone the teeth and extend blade life. The best way to break in new bimetal blades is by reducing the normal feed rate by half during this initial period. The band speed isn’t what breaks teeth during blade break-in; it’s the pressure an excessive feed rate produces that is most damaging.

To break in your bimetal saw blade, multiply the recommended blade speed by 25 percent, and cut that number of square inches. Be sure to run the blade at 50 percent of the recommended blade feed rate. Once you approach the end of the break-in period, gradually bring your band saw feed rate up to normal.
Use the Right Blade

The right band saw blade makes all the difference when cutting structurals, where the desired outcome is a clean, straight cut that simplifies weld prep applications. Be sure to choose a blade that can withstand the stresses of structural cutting, produce a smooth finish, and ensure maximum blade life. Also, optimal tooth geometry is key to creating faster cutting rates, which increase productivity.

Bandsaw Technology "moving on"

The last giant leap in band saw blade technology happened in the mid 1960s with the establishment of bi-metal technology, which was soon followed by the introduction of carbide-tipped blades.

Band sawing efficiency was limited prior to the advent of bi-metal blades. The band saw blade used to be made entirely of high carbon steel because it was pliable enough to withstand the stress caused by its winding path around the band saw machine’s drive wheels and through the saw blade guides. Because it was necessary to use a softer, more flexible backing material, manufacturers were prevented from capitalizing on the sawing efficiency that could be gained by using a harder material that would provide a more durable tooth edge.

Bi-metal and carbide-tipped band saw blades changed band sawing tremendously and permanently. Since then, advancements in tooth configurations, tooth geometry, edge materials and backing steels, in addition to improved methods for welding carbide-tipped teeth, have continued the band saw blade’s march toward increased productivity and blade life at a relatively steady pace.

Recent developments in second generation physical vapor deposition (PVD) coatings and tooth design constitute the latest big jump in band sawing, such as the one experienced with the introduction of bi-metal and carbide-tipped blades.

Second Generation Coatings
After being used on smaller cutting tools, such as drills, inserts and end mills for many years, coatings made their first marginally successful appearance in the band saw blade industry in the early 1990s. These first mono-block titanium nitride (TiN) coated blades were expensive and plagued by inconsistent manufacturing. Now, second generation coatings enable higher speeds and feed rates by making the tooth edge harder and tougher, protecting it from excessive abrasion and heat. Applying protective coatings to a band saw blade provides a demonstrable increase in productivity without decreasing blade life. These coatings are the next step of improvements that the band saw marketplace has been demanding—coated carbide for increased feed rate and coated bi-metal for improved blade life.

The last few years have seen blade manufacturers taking steps toward the mastery of the various processes (chemistry, material preparation, application technique and fixturing) necessary to apply coatings to larger cutting tools such as band saw blades. As manufacturers have improved their methods of applying coatings, coated blades have steadily gained industry acceptance, especially in high-production shops.

Manufacturers now offer a variety of blades with advanced, application-specific coatings such as titanium nitride (TiN) and aluminum titanium nitride (AlTiN) that deliver previously unheard of productivity and increased life.

Coated bi-metal blades combine the benefits of bi-metal with those of coatings, offering high sawing and feed rates in addition to increased blade life.

Band saw blade manufacturers are currently researching and developing the coatings of tomorrow. Nano-composite third-generation PVD coatings are among those currently being investigated.

The Up-And-Comer: Tooth Geometry
Manufacturers have been making improvements in tooth geometry at a slow and steady pace for years. The pace quickened in the mid 1990s, when progressive design technologies such as 3D machining simulation software arrived on the scene, making it possible to minimize field testing, which was typically long and costly. Using these new tools, innovations such as variable tooth height/set forms were optimized, helping shops get the most from their band-sawing investments.

New developments, such as the recent introduction of a band saw blade with a tooth design that provides a larger tooth cross section, indicate that there is more room yet for manufacturers to make big breakthroughs in tooth geometry. This particular tooth design’s increased cross section provides a reinforced cutting surface, which eliminates tooth strippage, prevents premature failure, reduces burring, removes chips more quickly for long life and provides low vibration and noise levels.

We can expect other manufacturers to follow suit with similar improvements in tooth design as we become increasingly aware of the ways in which even the minutest, but specific, changes in tooth geometry can affect cutting performance.

Breaking In a Bandsaw Blade

Bandsaw Blade Blade Break-In Procedure
All band saw blades, regardless of the manufacturer, need to be "broken in". When new, the teeth are just too sharp. Cutting at full rate will cause fracturing of the feather edges which will lead to premature blade failure. Breaking in a saw blade wears off this ultra sharp edge and allows the blade to retain its cutting ability longer. Each manufacturer has their own preferred method for blade break-in. However, they all share the same principles:
1. Maintain recommended band speed
2. Reduce feed pressure to ½ normal rate
3. Run at these settings for the first 50 square inches of material cut (150 square inches on mild and low carbon steel)
Note: If you are unsure what the normal feed pressure is, start light. Increase feed pressure until good, curly chips start to form. After cutting the recommended area, slowly increase the feed pressure until you reach your desired cutting rate.
Special consideration must be given while breaking in a saw blade on nickel-based alloys. (Stainless Steel, Inconel, Hastelloy, D2 Tool Steel, etc.) These alloys tend to work harden very quickly; therefore, sufficient feed pressure must be applied during the break-in period to remove some material. As a general rule, alloys sawed at lower speeds need more pressure during break-in period.
