Feed and Speed Rate Factors
Running saw blades at the correct feed and speed rates is important if the goal is to achieve desirable output. There is an optimum balance between blade speed and feed rate for every saw blade and every material to be cut. Proper adjustment of feed and speed rates will help to maximized blade life and assure a satisfactory cut. Feed rate is determined by the bandsaw, material size and shape, guide spacing, cutting fluid, and tooth size and shape. The greater the blade speed, the greater the feed rate — up to the limits imposed by the above-mentioned production factors. Blade Speed Bandsaw …
Horizontal and Vertical Bandsaws
Selection of horizontal and vertical bandsaws, like any other decision, depends on things like need, capabilities, and fit. Both can be used for woodworking and in metal fabrication shops. Horizontal bandsaw machines have the capacity to cut materials from soft woods to thick metals. Vertical bandsaw machines are used for cutting wood, metal, and plastic. Horizontal bandsaws hold the work piece stationary while the blade is moving back and forth through a cut. The configuration of the horizontal bandsaw helps to cut long materials. Vertical bandsaw machines need the operator to move the material against the blade to make a …
Bandsaw Blade Gullets
Bandsaw blade gullets are the space or curvature between each individual tooth on a saw blade. With each pass of the blade, the material being cut will curl into the gullet, creating a spiral of material called the chip. Too many teeth in the cut will make the gullet full. The teeth become filled with this excess material, and the chip will eventually break away. Use a variable pitch blade since the alternating pitch created increases and then decreases the chip load inside the cut. One reason to pay attention to gullet size is that with coarser pitch blades, the …
Bandsaw Blade Tooth Design
The machining industry uses four different types of bandsaw blade and each bandsaw blade tooth design is unique. Each set is made to correspond with a specific cut and material. The most commonly used tooth styles are the regular (or standard) tooth design and the variable (skip) tooth design. Each has its own specific purpose, with the definitions and usage being described as follows: Standard or Regular Tooth -Rake angle of Zero ° -For cutoff and contour cutting, or general purpose use Variable (Skip) Tooth Style -Same as Standard Tooth Style but with less teeth (every other tooth being removed) -Increased gullet capacity -Good …
Variable Pitch Bandsaw Blades
The variable pitch bandsaw blades, their unique qualities and applications, are designed for a particular reason. In this case, it is pitch. Saw blade pitch is defined as the number of teeth per inch — TPI — the number of teeth that come in contact with the material being worked. TPI has the ability to affect both the bandsaw blade’s performance and it durability. Too few teeth in the cut can lead to early stripping of the teeth. Conversely, too many teeth in a cut will greatly reduce the cutting rate and ultimately make the material impossible to cut. The choice of correct …
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 …
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 …
Band Saw Feed Rate and Feed System
Band Saw Feed Rate and Feed System. Feed Rate and Feed Systems in band saw operation are important cutting variables that impact production rate and machine-ability. So, what is Feed Rate and the various types of Feed Systems that exist? The Feed Rate is defined as the amount of material (in square inches) that a band saw can cut per minute. This number or amount is often referred to as S.I.P.M. (Square Inches Per Minute). Critical to the proper operation of a band saw is the smooth steadiness of the head of the saw as it drops onto the material being cut. The feed should always be …
