Metalworking is a rather laborious process.
Therefore, the equipment that is supposed to be used in this operation must be powerful and resistant to mechanical loads.
The durability of a cutting tool is the actual time period of the equipment before it breaks down.
When working on band saws, the durability of the equipment is considered as the ratio of the number of processed parts (in this case, the amount of cut material) in a certain time interval.
The format of measuring the total amount of materials in relation to one meter of the linear web of the belt mechanism can also be considered.
In some cases, it is possible to take the number of completed cuts as a rationing of equipment operation.
What factors influence the breakdown of a band saw?
Unfortunately, like any other industrial equipment, a band saw has its own working life, and after it expires, it is capable of breaking even despite the fact that this kind of saw is a fairly stable and strong tool in this industry.
The causes of various malfunctions of band saws are quite diverse.
Here are some of them: The saw teeth themselves may collapse if a processing area with a length of more than one hundred millimeters is selected.
With prolonged operation or various overheats, such a malfunction as a fracture of the canvases is possible.
Moreover, such a disaster can happen anywhere on the entire surface of the saw blade.
The working guide edges, which are responsible in the mechanism for adjusting the exact orientation of the saw blade, may wear out.
This failure is fraught with the so-called "withdrawal" of the saw to the side.
The workpiece being processed may be damaged in this case, since the cut will be uneven.
The back of the band saw blade is also capable of deforming during operation.
In more detail, this breakdown can be called a crease or crack in the back of the working tool.
Of course, at many domestic enterprises, the heads of mechanical services are constantly trying to reduce production costs by extending the service life of various equipment.
This aspect concerns band saws to one degree or another, since in many factories this equipment is one of the main ones, and without it the technological process can simply stop.
But at the same time, the cost of maintaining the tool is significantly reduced, placing the "lion's share" of the work on the technical maintenance personnel who monitor the equipment.
An example of such savings may be the refusal to purchase a spare part that has failed, and its restoration by the repair services of the enterprise.
This point is not always positively reflected in the further operation of the units, since not enough knowledge of repairmen can lead to faster wear of the repaired part or, due to poor repair, failure of other parts of the equipment.
Therefore, it is not always worth saving on spare parts when repairing equipment, as unforeseen factors may arise in the work, entailing a long downtime of the equipment itself.
Also, do not forget that the proper operation of mechanisms and machines also entails an extension of the operation of the units.
The equipment should not be overloaded to "peak" loads and should always be operated according to the recommendations of the passport data, described carefully in the operating manual, which is available for all commercially available equipment.
Let's look at some of the main factors that affect the durability of band saws: You always need to choose the right saw blade relative to the material being processed.
The parameters in this case can be various typical sizes of the cutting material, tooth pitch, tooth shape, and the mark of the surface to be treated.
When using band saws of various capacities, it is necessary to pay attention to the parameters that will directly characterize all cutting modes.
These parameters will be the cutting speed and the performance of the saw.
It should be noted that each group of materials and the format of the workpiece are cut at a certain speed and this speed limit should be strictly observed.
Otherwise, otherwise you can get a huge breakdown of the saw and it will result in a rather expensive repair.
All parameters of the band saw (including operating speed and equipment performance data) can be obtained in the technical operation and repair manual, which is attached to almost every industrial unit.
The various shapes of the processed materials and their brand also play a huge role in the stable operation of the saw.
The more complicated the size of the workpiece, the more the saw will perform operations, and therefore wear out.
The harder the metal, the faster the canvas can fail, heating up and erasing during processing.
The uniqueness of the design features of the band saw in production.
If the plant has a large area and large volumes of output, which should be further processed on a band saw, then a more high-performance machine should be taken.
These machines are made in the form of rigid structures with two columns and are necessarily equipped with various devices that provide feedback.
For easier production, machines of conventional power, made in the format of two racks or a cantilever arrangement of the saw frame, are suitable.
It is necessary to constantly monitor the technical condition, since a saw malfunction that is not fixed in time can lead to negative consequences and failure of other parts of the machine.
During operation, the level of lubricating fluid and cooling fluid should be constantly monitored.
If a new belt blade is installed on the saw, then before operation it should be qualitatively adjusted in relation to the workpiece at minimum speeds in order to avoid chipping of teeth and other deformations.
