Heavy-duty metal sawing systems are used in an array of industries to saw and cut metal workpieces. They have now expanded into different designs and structures but their working principle relies on one logic.
The saw presses down on the material during the cutting stroke and rises clear in the return stroke. The bandsaw has a flexible steel band wich is carried on rotating wheels mounted on parallel axes.
Metal sawing machines can be NC and CNC controlled. They offer several features like user-friendly touchscreens, and automated cutting functions with up to 100 programmes, ensuring accurate cutting.
Therefore, choosing the right one for your plant leads to better production of precise and clean-cut metal pieces.
In this article, we will share tips on how to choose the best metal sawing machine for your plant, asking some simple questions.
Not every workshop needs the same sawing investment. Do you usually cut one type of material or are you expanded on a range of different ones? Do you process them on a small to medium or large-scale fabrication? Can your business’s demands be met with just one or two sawing systems, or would be wiser to invest in more?
Looking closely at the patterns in your general fabrication will help answer a lot of questions in your purchasing journey.
For example, in construction fabrication, your type of finished product includes large and high thickness materials, such as large steel beams and heavy flat plates. For this, you would require more than one bandsaw on your shop floor to handle the daily workload.
Sawing machine systems that fit this description are the NC and CNC twin-column range of our Sterling heavy-duty, automatic bandsaws. Their wide variety of models and specifications guarantees a suitable machine for every working requirement and material of mild steel, stainless steel, or aluminium.
A twin-column bandsaw would help to cut the large-scale H I steel Beams and an additional high-quality blade to cope with the dynamic cutting pressure. Our Sterling bandsaw systems are always paired with our locally manufactured GoldCut blades.

GoldCut; manufacturing the blades for all your cutting needs
Band saws are built with different blade types. According to your requirements, you can choose machinery with extremely accurate blade types, blades that don’t throw sparks, or blades that go especially well with heavy-duty, high-mix production.
Metal cutting blades are usually coated with carbide or ceramic blends. This helps them to cut hard and rigid materials without building up heat. This also helps to achieve clean cuts and better longevity of the tool overall.
For example, abrasive disc blades are lightweight and affordable, making them perfect for small workshops or less complicated products. They cannot create burr-free results but are relatively precise and clean. If heavy blades are what you need, cold saw blades are a version, which is also very accurate and doesn’t produce spars.
As we mentioned before, the core of the saw is the blade, wire, or chain used to cut the metal workpiece, by placing the edge against the material and applying force. The pressure force is applied by water, electricity, or other energy sources. It is very important to choose the right kind of power source. This leads to better performance and overall efficiency.
For example, if your line of work requires heavy-duty machinery, you can opt for gas-powered sawing machinery.
If, on the other hand, you need something less powerful, you can stick to a lighter version, like sawing machinery with rechargeable batteries, with or without cords, depending on your requirements.
Another detail to watch out for is the teeth count. The blade’s teeth are designed to keep an optimal temperature of the blade and workpiece avoiding heat build-up. Sharp teeth are made with stainless steel or aluminium oxide and all blades are coated before starting an operation in order to reduce sparks.
Pay attention to the teeth per centimetre ratio to choose the right blade type. Blades designed for burr-free results usually have up to 10 teeth every 2.5 cm. An optimal tooth count is close to 6 to 8. However, this depends on the size and type of material you are cutting.
A metal sawing machine can cut various metals and workpiece structures. Make sure to understand the line of work you’re in and what is the most suitable machine for your product. Talk with your operators and engineers to make a quick assessment before starting your purchasing journey.
Different operations require different time, technology, power, and energy to make, so knowing and communicating your requirements well is crucial in a purchasing journey.
If your work is based mostly on smaller materials and basic sheet metalworking, you could go for a smaller capacity pull-down or semi-automatic bandsaw to cut small to medium materials such as box & pan, and small U and I Beams.
If you’re looking for horizontal semi-automatic bandsaws, feel free to contact us and we will walk you through our Bianco and Sterling machine systems.
Another important factor is the machine size. Most metal sawing machines range in size from 10 to 100 feet in length. Make sure you buy only what fits your needs.
When you use the metal cutting saw for long, uninterrupted periods of time, you will experience fatigue.
This can lead to more errors during production, and more sparks and burrs. Some sawing machinery can provide a clean finish even after a long-running time. If your production process requires the machinery to stay in working mode for too long, have a talk with a professional that can help you filter the right options.
In the end, remember that this investment is a very long-term one. You are going to keep your future metal cutting saw for years to come, and the performance has to be the same. So you want to ask about tooling, part quality, cleaning and additional maintenance costs.
