Determining the durability of band saws For a band saw, as for any other metalworking tool, the characteristic of durability is important.
This is the period of time during which the saw is continuously working, without requiring overfilling (or at the end of which it fails).
How to evaluate the durability of a band saw?
There are several options for assessing the durability of the band saw blade: the total amount of processed material in m2, the amount of material per meter of the saw blade (m2 / m linear), the number of cut blanks (pieces, cuts).
Signs of failure of the band saw: the teeth are destroyed in an area longer than 10 cm, the blade has ruptured, wear of the cutting edges leads to a "withdrawal" (deviation) of the cut from the required straight line, the back of the blade is worn or crumpled.
What determines the durability of a band saw The durability of a band saw depends on a number of factors: The right choice of cutting speed and productivity.
Recommended ranges are specified by the manufacturer.
The higher the performance, the lower the durability.
The correct selection of web parameters for specific workpieces.
The choice of the shape of the saw teeth is made in accordance with the material of the workpiece, the pitch of the teeth is in accordance with the dimensions.
The shape, brand and quality of the material of the blanks.
A decrease in durability is observed when sawing thin-walled pipes, profiles, hard-to-work metals, heterogeneous workpieces containing sand, shells with scale on the surface.
Design features of the equipment.
Industrial machines are more productive.
The width of the web increases durability.
The technical condition of the equipment.
It is necessary to regularly check the tension of the web, the parallelism of the pulleys, and the fastening of the frame.
The quality and concentration of coolant.
Low-quality coolant reduces durability by 10-20%.
The quality of the run-in of the new canvas.
The new saw must first operate at reduced operating modes.
