Bandsaw Blade Terminology

With regard to bandsaw blade terminology, it is important to note the different types of saw blade teeth, the terminology, and their usage. Hopefully, this post will help to clear up any misconceptions while offering sensible advice toward the purchase of a new saw blade for a particular cutting operation. Here they are in no particular order: Regular Tooth Style:  zero° rake angle on the blade tooth; full, well rounded gullets, a strong supporting back tooth, and all tooth shapes are the same. Skip Tooth Style:  zero° rake angle on the blade tooth, skip tooth style blades have double the gullet capacity in …

Speed and Feed Rates

The relationship between Speed and Feed Rates is vital to the proper function of a bandsaw and requires a saw operator’s full attention or the bandsaw will fail to perform as expected. Speed Rate A saw blade’s speed is defined as the distance in feet that the blade travels per minute: a measurement of S.F.P. M. or Surface Foot Per Minute. In order to achieve proper blade speed, the SFPM must be optimum for the application. The drive belts cannot be slipping under the load being machined, and the tachometer needs to be checked often in order to assure that the proper RPM’s are being …

All About TPI (teeth per inch)

Here at Sawblade.com, questions arise with regard to perceived saw blade problems. After a few inquiries, it can be determined if the machine operator made any miscalculations with speed and feed, the materials being cut, TPI, and any other variable that ends up impacting the cutting process. In most cases, the customer already knows exactly what is needed. The operator knows the blade size, length and width, the thickness of the blade being ordered, and they know the materials to be cut so there is often no need to ask about carbon, bi-metal, or carbide blades or the proper tooth pitch required for that particular job. There …

Bandsaw Guides and Saw Blade Replacement

Bandsaw Guides and Saw Blade Replacement: blade guide information and the safe replacement of bandsaw blades. First, a Blade Guide is a small, molded piece of porcelain (generally) which allows a bandsaw blade to track along a consistent path and functions to keep the blade flat on a steady track as it moves with the saw mechanisms. The guide functions with an adjuster knob, raising the guide up and down to accommodate different material thickness. Roller Guides are used on small machines, or when blade speeds run over 600 SFPM. They are flat discs, almost like washers, and must retain blade tightness in order …

Vertical Bandsaw Vibration

Vertical Bandsaw Vibration There are a number of reasons why vibration may occur during the use of a bandsaw machine. The saw blade speed and the types of saw blades being used, if incorrect in either case, have the tendency to cause vibration. The tooth pitch and speed rate need to be adjusted for the materials being cut in order to avoid vibration from happening. Vibration may occur during a break-in process, or if the saw blade is tripped on the work piece. Decrease speed during break-in and slowly increase the feed rate to help prevent vibration from occurring. Other issues …
