What is the burr on the cut surface of a horizontal bandsaw machine?

As a supplier of horizontal bandsaw machines, I've been getting a lot of questions lately about the burr on the cut surface of these machines. So, I thought I'd take a moment to explain what it is, why it happens, and what you can do about it.

What is the Burr on the Cut Surface?

A burr is a raised edge or small piece of material that remains attached to the cut surface after a sawing operation. It's like a little rough patch or a tiny ridge that you can feel when you run your finger along the cut edge. You might not always see it right away, but it can cause problems down the line, especially if you're working on a project that requires a smooth, clean finish.

Why Does the Burr Occur?

There are several reasons why a burr might form on the cut surface of a horizontal bandsaw machine. Here are some of the most common ones:

• Dull Saw Blade: If the saw blade is dull, it won't cut through the material cleanly. Instead, it will tear and rip at the material, leaving behind a rough edge and a burr. It's like trying to cut through a piece of paper with a blunt pair of scissors - you'll end up with a jagged edge.
• Incorrect Feed Rate: The feed rate is how fast the material is fed into the saw blade. If the feed rate is too fast, the saw blade won't have enough time to make a clean cut, and a burr will form. On the other hand, if the feed rate is too slow, the saw blade can overheat, which can also lead to burrs.
• Improper Blade Tension: The blade tension is how tight the saw blade is on the machine. If the blade tension is too loose, the blade can wobble as it cuts, causing a rough cut and a burr. If the blade tension is too tight, the blade can break or wear out quickly.
• Material Hardness: Different materials have different hardness levels. Some materials, like soft metals or plastics, are easier to cut than others. If you're cutting a hard material, like stainless steel or titanium, you might be more likely to get a burr on the cut surface.

How to Reduce or Eliminate Burrs

Now that we know what causes burrs, let's talk about how to reduce or eliminate them. Here are some tips:

• Use a Sharp Saw Blade: This might seem obvious, but it's important. Make sure you're using a sharp saw blade that's appropriate for the material you're cutting. You can sharpen the blade yourself or have it professionally sharpened.
• Adjust the Feed Rate: Experiment with different feed rates to find the one that works best for your material. You might need to slow down the feed rate for harder materials or speed it up for softer materials.
• Check the Blade Tension: Make sure the blade tension is set correctly. You can use a tension gauge to measure the tension and adjust it as needed.
• Use a Coolant: A coolant can help keep the saw blade cool and lubricated, which can reduce the risk of burrs. You can use a water-based coolant or a cutting oil, depending on the material you're cutting.
• Deburr the Cut Surface: If you still have a burr on the cut surface, you can use a deburring tool to remove it. There are several types of deburring tools available, including hand tools and power tools.
