Bandsaw Chips Check
Fabricating shops use bandsaw machines to cut a variety of materials including beams, structurals, heavy wall tubing, stainless steel, tool steels , pipes, and tubes. Bandsaw operators incorporate an effective sawing operation by first choosing the right bandsaw blade, and then performing a blade break in procedure. These are then followed by properly setting the machine, using the correct feed rate for the material, running the saw blade at the recommended speed rate, and cutting with or without coolant (depending on the materials). But there is one aspect that most bandsaw operators do overlook, and that is to check the shavings …
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 …
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 …
