BREAKING IN THE BLADE How to guarantee that your new blades last longer WHAT IS BLADE BREAKING IN? New blade teeth are razor sharp. Before using the blade at the standard parameters, the tip of each tooth should be honed to create an extremely small radius on its tip. Not honing the cutting edge can cause microscopic cracks that reduce blade duration. A blade that is honed correctly with the right breaking-in procedure lasts much longer. HOW TO BREAK IN A BLADE Choose the right cutting speed for the material to be cut. Reduce the cutting rate so it is 20% to 50% slower than normal (the...

KAIZEN SERVICE KAIZEN SERVICE: HOW DOES IT WORK? It follows the S P D C A (Scan, Plan, Do, Check, Act) logic. Our engineers come to your cutting departments, they work with your operators and teach them how to approach and use instruments and techniques. Our engineers observe, then collect all the necessary data from every machine and together develop new solutions to improve the process and reduce cutting costs. The service is free and you will be given a report complete with all the data and possible solutions. THE ADVANTAGES OF ROUTINE MAINTENANCE Programmed maintenance must always be...

CUTTING RATE Cutting rate Tooth size 10/14 8/12 6/10 5/8 5/7 4/6 3/4 2/3 Multiplier (MR) 4,016 3,341 2,667 2,160 2,058 1,721 1,215 0,843 After having determined the right teeth and the cutting speed, select the MR multiplier for the selected tooth and use this formula to calculate the cutting rate in mm/min. In examples 1 and 2 you can see the difference in the cycle time when cutting a piece that is the same but positioned differently (example 1 short side or example 2 long side in contact with the blade). As you can see, a finer pitch can be used if the blade comes into contact with the...

GUIDE FOR CORRECT BAND SAW BLADE USE Choosing the blade width The blade width is the distance between the tip of the tooth and the back. The wider the blade, the greater its resistance to arcing while cutting. For straight cuts use the maximum width permitted by the machine. With arced cuts, however, choose the maximum width permitted by the radius of cut. To respect the tolerance of the radius of cut always consider not just the blade width but also the thickness of the material, its workability, the cutting rate and the starting point. SERRATION The serration of a blade is defined by the...
