BLADE BREAK-IN Using the right break-in procedures for a bimetal blade assures longer blade life, faster cuts for a longer period of time and consistent performance. Conversely, blade life can be significantly compromised if the proper break-in procedures are not followed. LONGER BLADE LIFE NEW BLADE WITH RAZOR SHARP TEETH TOOTH CORRECTLY BROKEN IN The teeth on a new band saw blade are razor sharp. To withstand the cutting pressures of band sawing, the tip of each tooth should be honed to create an extremely small radius on its tip. Easy-to-cut material such as carbon steel and aluminum: A.Run the normal surface feet per minute (SFPM). B.Adjust the feed pressure to about one-half the normal cutting rate for the first few cuts or for 50-100 square inches (323-645 sq.cm). C.Increase to the normal cutting rate. D.Avoid vibration. Hard-to-cut materials such as nickel-based alloys like inconel, hardened steels,tool steels and stainless steels: A.Run the normal surface feet per minute (SFPM). B.Adjust the feed pressure to about threequarters of the normal cutting rate for the first few cuts or for 25-75 square inches (161-484 sq.cm). C.Then increase the cutting rate part way to normal for the next few cuts. D.Then increase to the normal cutting rate. E.Avoid vibration. BAND SAW SERVICE & SUPPORT Starrett service technicians are available to tune up and perform preventative maintenance on your production sawing machine using Starrett Band Saw Blades, at no additional cost. They fully review machine condition, blade mounting and operation in detail, making adjustments, as required, to help maintain good sawing and long life for both the machine and blades. TRAINING TOOTH INCORRECTLY BROKEN IN START TO CUT MATERIAL AT REDUCED CUTTING RATE Starrett service technicians can also instruct saw operators on achieving the best performance of blade and machine for your applications. Contact your Starrett Band Saw distributor about arranging a visit to your workplace by a Starrett service technician. AFTER BREAK-IN WHEN THE BLADE HAS FULLY ENTERED THE WORKPIECE, INCREASE THE FEED RATE OVER A SERIES OF CUTS UNTIL THE RECOMMENDED CUTTING RATE IS ACHIEVED BAND SAW BLADE INSTALLATION GUIDELINES Always follow the machine manufacturer’s instructions and recommendations for blade changes and the safe operation for the band saw machine. The guidelines are not intended to replace the machine manufacturer’s instructions or recommendations. The general information contained in the guidelines is intended to assist in the proper installation of band saw blades. Proper blade installation achieves more efficient blade performance. Please contact your machine manufacturer for appropriate procedures for blade changes for your specific machine and your saw blade manufacturer for appropriate cutting recommendations. The L. S. Starrett Co. nor its employees, shall not be held responsible for the accuracy or completeness of these guidelines. cWear gloves when handling band saw blades. cWear eye protection, safety shoes, and hearing protection. FOLLOW INSTRUCTIONS CAREFULLY cFollow all the safety instructions shown in the band saw machine operator’s manual and on the machine labels. Recognize and read safety and warning signs such as Danger, Warning and Caution. cFollow the saw blade installation instructions for the make and model of the band saw machine. BASIC BLADE CHANGE GUIDELINES cPosition saw head to appropriate location to facilitate ease of blade change. cFollow required lock out tag out procedures. cPosition chip brush away from saw blade. cRelieve saw blade tension and remove blade. cRemove wheels. any chips from saw guides and band cSelect appropriate blade for cutting application. (Refer to saw blade selection chart) cUnfold blade properly. Do Not Throw. Throwing the blade will result in tooth damage that will reduce saw blade performance. (Refer to unfolding procedure) cInstall blade with saw teeth pointing in proper direction. cApply appropriate tension to the blade. cBe aware of pinch points and keep hands and clothing clear of rotating blade. cAdjust guide arms to appropriate positions to workpiece. cAdjust blade guides for proper blade support. cAdjust chip brush to fully engage saw blade teeth to ensure proper chip removal. cCheck hydraulic fluid levels if applicable. cEnsure appropriate cutting fluid placement and mix ratios as applicable per machine, cutting fluid, and blade manufacturer’s recommendations. cBreak in blade properly before reaching desired cutting rates.
