Understanding Aluminum’s Unique Properties
Learning about the characteristics of aluminium is essential before moving on to tool selection. In contrast to heavier metals like steel, it is very malleable, strong, and lightweight. Because of these qualities, aluminium is not only a desirable material, but it also requires specific tools and equipment to be worked.
Aluminium, a member of the carbon and boron families of elements, possesses characteristics common to both metals and nonmetals. Producing commercially viable, pure aluminium requires processing bauxite ore, even though aluminium is one of the most abundant elements on Earth.
The next step is to sort aluminium into a 4-digit series, from 1xxx to 8xxx, based on the alloyed elements. Copper, magnesium, silicon, manganese, and zinc are elements that are commonly added. Because of these, a wide variety of alloy compositions are possible.
The appearance and fabricability are influenced by these particular alloy compositions. When compared to pure aluminium, alloyed aluminium has superior strength, flexibility, corrosion resistance, conductivity to electricity, and density.
Types of Aluminum Cutting Tools
Hand tools
Hacksaws
Commonly utilised in woodworking and on construction sites, a hacksaw is a cutting tool that comprises of a frame and a blade.
Aviation snips
Aviation snips, crafted from durable alloy steel, are ideal for slicing through various materials, including thin sheet metal, aluminium, and plastic. There are three different kinds: left-cutting, right-cutting, and straight-cutting. The snips' blade type is determined by their quality.
Nibblers
Mechanical nibblers are a time and labour saver when compared to hand twisting when cutting plastic or metal at connection points; they find widespread use in model making.
Like the back half of pliers, they resemble scissors but have smaller, thicker heads. A wire stripper is a feature on some nibblers, while others are specifically made to cut wires.
Power tools
Circular saws
Steel can be easily cut with a toothed circular saw. Just like cutting through 2×4's with a traditional pipe, metal circular saws can effortlessly cut through steel.
Circular saws have improved chip handling, eliminated heat transfer, and sped up metal cutting compared to previous models thanks to their innovative tooth designs and materials.
Jigsaws
Jigsaws are a type of sawing machine that use a track to move a sliding guide, also called a roller, on which the blade is mounted. A feeding mechanism is used to accomplish the sawing process.
Band saws
Machine tools known as band saws are utilised for the purpose of cutting a wide range of metals. Their structural differences allow us to divide them into horizontal and vertical varieties, while their functional differences allow us to categorise them as semi-automatic, fully-automatic, or CNC.
You can further categorise horizontal band saws into scissors and double-column varieties.
CNC routers
Among the many uses for CNC routers are the carving of relief, flat, and hollow patterns into a variety of materials, including electric wood, wood, jade, plastic, glass, acrylic, and aluminium alloys. They carve with great speed and accuracy.
Grinding Wheels
For aluminium, use grinding wheels made for that material. In order to guarantee effective and efficient grinding, these wheels are designed to reduce the likelihood of clogging and loading.
Inspect the Grinding Wheel:
Check the grinding wheel thoroughly for wear and damage before you begin. It must be mounted correctly and fastened to the grinder securely.
Coolant or Lubricant:
To keep the grinding wheel from overheating and cutting its life short, use an appropriate coolant or lubricant while you work. In addition to keeping the work area clean and safe, it aids in reducing the formation of aluminium dust.
Tips for Successful Aluminum Cutting
Selecting an Appropriate Saw Blade
Industrial aluminium profiles are easier to work with than steel because of their lower hardness. They aren't very hard, though, so they can also stick to the blade. As a result, you should always use new, sharp blades.
How to Pick the Right Lubricant:
Without lubricant, cutting aluminium profiles leaves a surface covered in numerous burrs that are a pain to remove. The saw blade will also be damaged by this.
Maintaining a precise cutting angle:
While right-angle cuts are the norm for industrial aluminium profiles, angled cuts, like 45 degrees, are sometimes necessary. Careful control of the angle is required when cutting at an angle. For this, a CNC sawing machine is your best bet.
Safety Considerations
1. We need to give the machine a quick run before beginning the operation to make sure everything is running smoothly.
2. Operators must maintain complete concentration while cutting aluminium profiles; they must not look away or play around in any way.
3. It is important to wait for the saw blade to reach normal speed when cutting aluminium profiles. Always wear the safety cover and maintain a distance of at least 15 cm from the blade when operating the machine.
4. Wait for the saw blade to stop before releasing the cylinder gripping mechanism to remove the sawn aluminium profile while operating a fully automatic cutting machine. Avoid wiping down the machine's aluminium chips.
5. Neither the operator nor their arm should ever be in close proximity to the saw blade or the operating table while the cutting machine is in use.
6.Cut power to the machine immediately and have an expert take a look if anything out of the ordinary happens while it's running (smoke, strange noise, heat, sparks, etc.).
It is the obligation of every manufacturing facility to ensure the production process is safe by reducing needless risks, providing frequent training to workers, and adhering to processing orders and principles.
Protective Clothing and Equipment
The safety of workers depends on their having the proper protective gear. With these, you can do your job with much less risk and complete assurance that you are well-protected. The rule of thumb is that you'll get more done if you can reduce your stress levels.
Some protective equipment may include:
- A hard hat
- A back brace
- A pair of gloves
- Steel-toed work shoes
- Goggles
- Work uniform
Taking precautions is more of a habit than an inconvenience in an aluminium fabrication shop. By incorporating safety measures into your daily routine, you can create a safer and more efficient work environment.
