Widely used in DIY workshops and metal stores, Aluminium is one of the most versatile metals. While easy to machine, aluminium does present some challenges. In fact, it’s often because aluminium is so easy to machine that some novice machinists can screw up their cuts. Aluminium is soft, heats up quickly, and can deform or bend if not cut properly. At best, this leaves more work for the mechanics. At worst, it can ruin an otherwise good project. That’s how vital it is to use the right way with the right cutting disc to achieve the perfect cutting aluminium every time.
Aluminium Cutting with Cutting Disc Tips
- Cutting disc rotates very fast, which causes the hot sparks and chips to fly quickly. To protect your safety, goggles, heavy-duty work gloves, protective footwear and ear protectors are recommended.
- First select the best cutting disc for aluminium, then check that the maximum rpm of the disc is higher than the maximum rpm of the tool; this will prevent the disc from being overstressed and broken, resulting in serious injury.
- The disc has two forms: a flat surface, a convex center, and a concave center. The raised and lowered center discs are well suited for entering narrow corners and cantilever because they allow access to the aluminium at different angles. Do not drive these discs too deeply, as the changed disc geometry may block and damage the disc.
- Firmly clamp the workpiece near the desired cutting point or ensure that the workpiece cut from it is strong and does not fall during operation.
- Run the grinder for about a minute to check that the tools and discs are installed correctly to ensure that any balance or installation problems are found before starting work.
- When starting to cut, always place the blade at a 90-degree angle to the workpiece, taking care to ensure that the shield is between the worker and the workpiece. Avoid impacting the aluminium or hitting the disc against the aluminium, and always place the cutting blade in the thinnest part of the aluminium. Because the surface is evenly contacted, it is easiest to machine circular contours, such as “I-beams” and box sections. The outline should start from the corner. Reduce friction. Don’t put too much pressure on it, just let the best cutting disc for aluminium get the job done.
- If needed, it is useful to use a wire brush after corner grinding to deburr and smooth the burrs.
