What are the problems with aluminum cutting?

Alu alloy refers to a “compound material” consisting of aluminum metal and other elements to improve performance characteristics. Other elements many include copper, magnesium silicon or zinc, just to mention a few.

Alloys of aluminum have exception properties including better corrosion resistance, improved strength and durability, just to mention a few.

Aluminum is available in a number of different alloys and each series may have several different tempers in which to choose. As a result, some alloys may be much easier to mill, shape or cut than others. It is vital to have a complete understanding of the “workability” of each alloy, because they have such different properties.

These find use in a wide range of industries, including automotive, marine, construction, and electronics.

However, cutting and grinding aluminum effectively and efficiently can be challenging for several reasons. Aluminum is a softer metal with a lower melting point than other materials, such as steel. These characteristics can lead to loading, gouging or heat discoloration when cutting and grinding the material.

Aluminum is soft by nature and can be difficult to work with. In fact, it may form a gummy buildup when cut or machined. This is because aluminum has a relatively low melting temperature. This temperature is low enough that it will often fuse to the cutting edge due to the heat of friction.

There is no substitute for experience when it comes to working with aluminum. For example, 2024 is not too difficult to work with, but is nearly impossible to weld. Each alloy has properties which give it advantages in some applications but can be disadvantages in others.

CHOOSING THE RIGHT PRODUCT fOR ALUMINUM

Perhaps the most important factor to consider with aluminum machining is the machinist. Understanding the properties of aluminum is essential but so is choosing the right tools and knowing how to set the parameters for the machining process. Even with CNC machining methods, one must take many things into account or you could end up with a great deal of scrap, and this can take away any profits you make from the job.

There are many tools and products available for cutting, grinding and finishing aluminum, each with advantages and disadvantages. Making the right choice for the application can help companies gain better quality, safety, and productivity, while also minimizing downtime and labor costs.

When machining aluminum, you need very high cutting speeds to get the best results. In addition, cutting edges must be hard and very sharp. This kind of specialized equipment can represent a substantial investment to the machine shop on a limited budget. These costs make it wise to rely on an aluminum machining specialist for your projects.

Analysis and solutions to problems with abnormal noise

If there is an abnormal sound when the saw blade is cutting aluminum, it is likely that the saw blade is slightly deformed due to external factors or excessive external force, thus triggering a warning.

Solution: Recalibrate the carbide saw blade.

The main shaft clearance of the aluminum cutting machine is too large, causing jump or deflection.

Solution: Stop the equipment and check to see if the installation is correct.

There are abnormalities in the base of the saw blade, such as cracks, blockage and distortion of the silencer lines/holes, special-shaped attachments, and other items other than the cutting material encountered during cutting.

Solution: Determine the problem first and handle it accordingly based on different causes.

Abnormal noise of the saw blade caused by abnormal feeding

The common cause of this problem is the slipping phenomenon of the carbide saw blade.

Solution: Readjust the saw blade

The main shaft of the aluminum cutting machine is stuck

Solution: Adjust the spindle according to the actual situation

The iron filings after sawing are blocked in the middle of the sawing path or in front of the material.

Solution: Clean up the iron filings after sawing in time

The sawed workpiece has texture or excessive burrs.

This situation is usually caused by improper handling of the carbide saw blade itself or the saw blade needs to be replaced, for example: the matrix effect is unqualified, etc.

Solution: Replace the saw blade or recalibrate the saw blade

Unsatisfactory side grinding of the sawtooth parts results in insufficient accuracy.

Solution: Replace the saw blade or take it back to the manufacturer for regrinding.

The carbide chip has lost its teeth or is stuck with iron filings.

Solution: If the teeth are lost, the saw blade must be replaced and returned to the manufacturer for replacement. If it is iron filings, just clean them.

FINAL THOUGHTS

Because aluminum is much more malleable and less forgiving than steel — and more expensive — it’s important to pay close attention when cutting, grinding or finishing the material. Remember that aluminum can be easily damaged with overly aggressive practices. People often measure how much work is being done by the sparks they see. Remember, cutting and grinding aluminum does not produce sparks, so it can be harder to tell when a product is not performing as it should. Check the product after cutting and grinding and look for large aluminum deposits, paying close attention to the amount of material being removed. Applying the proper pressure and reducing the heat generated in the process helps address the challenges presented when working with aluminum.

It’s also important to choose the right product for the application. Look for high-quality, contaminate-free products that are designed for use with aluminum. The right product coupled with key best practices can help produce quality results, while also reducing the time and money spent on rework and scrap material.
