Posted on 5th March 2020

When working alongside a bandsaw machine, it’s not unheard of to encounter problems with the overall performance of your blade every now and again. Working to maintain the quality and integrity of your metal cutting bandsaw machine can sometimes seem like a relatively menial task, however, through following just a few simple steps, you could successfully extend the lifespan of your saw blade by up to 30%. Through the employment of the following recommendations to the application of your saw blade, you can work to greatly improve its cutting performance, allowing the blade in question to uphold its value for a much longer time in comparison.
Below, we work to discuss some of the common cutting performance issues seen to occur during the application of industrial bandsaw blades, how to fix them, and what could be seen as the initial cause of the problem, helping to reduce the risk of the same issue occurring again.

Inaccurate Cut

If your bandsaw blade is experiencing issues resulting in an inaccurate cut being gained within your cutting project, this is a problem that could be seen to stem from a number of causes, including:

  • Guide arms being too far apart
  • Blade being worn out
  • Under or over feeding
  • Improper tooth pitch
  • Cutting fluid not being applied correctly
  • Guides being too loose or worn

Issues of an inaccurate cut as a result of the guide arms of your metal cutting bandsaw machine being too far apart are easily resolved by working to ensure that guide arms are properly adjusted to be closer to your cutting material throughout application within the future, helping to ensure that this is a problem that does not work to re-occur. Problems caused by the blade being worn out are also very quickly and simply resolved by replacing the blade.
If issues are stemming from the under or over feeding of material to your industrial bandsaw, it should be ensured that the cutting recommendations for your blade and machine are referred to as to guarantee proper use and help you to avoid repeat problems within the future. Cutting guidelines should also be followed in situations where inaccurate cutting results are seen as a result of improper tooth pitch; using proper tooth selection will allow users to avoid this problem.
If cutting fluid not being applied properly is causing inaccurate cutting within your application, adjusting the coolant nozzle will easily resolve this, whereas, if issues are stemming from guides being too worn or loose, these will either need to be tightened or replaced.

Rough Cut

If a rough, low quality cut is being gained from your cutting application, this may be a result of a multitude of various causes:

  • Damaged or dull blade
  • Incorrect feed or speed
  • Blade not being properly supported
  • Low blade tension
  • Incorrect tooth pitch
  • Guide arms being too far apart

If issues of a rough cut are seen to be gained as a result of improper feed or speed, the user should look to the cutting recommendations for their bandsaw machine, helping them to avoid this problem from re-occurring in the future. This is also true for issues caused by low blade tension; referring to the operator’s manual can assist in helping to easily resolve any problems being seen. As previously mentioned, if the guide arms of your bandsaw machine being too far apart is causing problems, this can be solved by working to make sure that guide arms are adjusted to be closer to the cutting material throughout your application, and improper tooth pitch is solved by using the proper tooth selection for your project.
If you find that your industrial bandsaw blade is not properly supported, resulting in the gain of a rough cut, guide arms should be adjusted or tightened to achieve a better quality cut. If the blade used within your application is dull or damages, a new blade is to be installed.

Some of the most common issues seen with the cutting performance of bandsaw blades are easily fixed through working to follow the recommended procedures for your machine, preventing the re-occurrence of issues and ensuring that your bandsaw runs as smoothly as it can.
