Cutting costs through the right band saw blade
In machining shops large volumes of piping and tubes are being cut which requires band saw blades Toronto with the best combination of cutting performance and fatigue life. Blades can be made from one piece of metal or built from two pieces based on the performance and life expectancy required. Bimetal band saw blades are high speed steel edge materials that are electron beam welded to fatigue resistant spring steel backing. When this type of band saw blades Canada were introduced 20 years, they immediately offered significant improvements in blade durability compared to the carbon blades that were made from carbon steel with a hardened back and tooth edge. The new variations of the bimetal band saw blades have been proven suitable in cutting bundles or structural shapes like pipes and tubing.
The latest bimetal blades feature high speed steel cutting edges that are manufactured with more carbide and higher percentages of carbide-forming alloys that include chrome, molybdenum, tungsten and vanadium. The result is the carbide-tipped blades that are harder, tougher and more wear resistant with teeth that retain their sharpness for longer period of time.
Cutting costs through right feed rate
Feed is the term used for the depth of penetration of the tooth into the material that is being cut. In order to achieve cost effective cutting, it is important to remove as much material as possible in short time by using a high feed rate/pressure that the band saw machine can handle. However, feed is limited by the machinability of the material being cut and the life expectancy of the blade. Cutting can be made faster but it will compromise the life of the blade. A deeper feed will result into lower shear plane angle while a lighter feed will increase the shear plane angle that will increase the cost per cut. In order to determine the right feed rate, examine the chips and evaluate their shape and color.
The goal in cutting is to achieve chips that are thin, tightly curled and warm to the touch. If you notice that the chips have turned from silver to golden brown, it means you are forcing the cut and generating too much heat. If the color of chips is blue, it indicates extreme heat that will shorten the life of the blade. Adjust accordingly based on your monitoring of chip formation.
