It is known from practice in production that the tension force of the band saw in the band saw machine affects the quality of the saw blade.
Problems that arise when cutting through the web If there is insufficient tension when cutting through the web, then the cut will be uneven.
You will have to additionally leave a large canvas allowance, and sometimes introduce an additional technological operation in order to properly process the ends of the workpieces.
These operations are costly, because you have to spend both money and time to process the ends of the workpieces.
In production, this is a huge disadvantage.
If you additionally leave a large margin of the blade, then the blade may jam during cutting, which will lead not only to the breakage of the saw, but also to the failure of the machine itself.
If you tighten the band saw in the band saw machine too much, a breakage of the web may also occur.
At the same time, the consumption of coolant increases, since the "overstretched" cloth heats up more.
Band Saw tension Studies Nordex has conducted band saw tension studies in a band saw machine.
Studies have shown that the optimal value of the tension force for a band saw is 300 N/mm.
After the research, the company's specialists developed a special device — a speedometer, which is used in production in order to correctly set the tension force of the saw blade.
One of the most important parameters for the technological mode of operation of equipment in production was also taken into account — the cutting speed of the web.
Advantages of the Nordex speedometer It is important to note that almost a third of modern band saws are equipped with control devices that do not give correct data on the cutting speed of the blade.
This is because the control devices do not take into account the errors that appear due to wear of the drive.
Thanks to the Nordex speedometer, wear and many other errors can now be taken into account.
The Nordex speedometer is easy to use, accurate and reliable.
The data obtained with the help of the Nordex speedometer allows you to accurately set the technological modes of operation of the band saw, and this saves equipment life and reduces operating time and the number of blanks rejected by the quality of the cut.
