With the widespread application of aluminum alloys in aerospace, automotive manufacturing, and architectural decoration, their sawing technology has also attracted increasing attention. Aluminum alloys are characterized by their relatively soft texture, low melting point, and rapid heat conduction. Therefore, during sawing, problems such as saw blade adhesion to aluminum, large burrs on the cut, and burning are easy to occur, and may even damage the saw blade and workpiece. To improve processing efficiency and safety, mastering scientific and reasonable sawing techniques is particularly important.
First, safety is always the top priority in the processing process. Operators should wear safety glasses, cut-resistant gloves, hearing protection, and dust masks to ensure personal protection. At the same time, the workpiece must be firmly fixed using a fixture, and hand-held workpiece cutting is strictly prohibited to avoid accidents. Before the equipment is running, a comprehensive inspection should be carried out to ensure that the protective cover is intact and the equipment is in good condition. The work area should be kept clean to eliminate tripping hazards. In addition, when changing saw blades or performing maintenance, power must be cut off to ensure personal safety.
Second, choosing the right saw blade is the key to improving cutting quality. It is recommended to use carbide tipped ( TCT) saw blades specifically designed for aluminum alloys. The number of teeth is usually recommended to be 60-100 teeth (10-inch saw blade) to achieve good cut quality and chip removal effect. In terms of tooth shape, it is recommended to use a zero or slightly negative rake angle design, combined with alternate bevel teeth (ATB) or trapezoidal flat teeth + bevel teeth (ATBR) combination, which helps to reduce burrs and improve cutting stability. Equipment parameter settings are also crucial. During cutting, the speed should be appropriately reduced. The ideal speed is generally controlled between 2000-2500 RPM to avoid aluminum adhesion or burning due to high-speed cutting. The cutting depth should be slightly higher than the workpiece thickness by 3-6mm to reduce friction and heat accumulation. Lubrication and cooling play an important role in aluminum alloy sawing. It is recommended to use a special cutting fluid or a mixture of kerosene and machine oil. If conditions are limited, lubricating wax can also be used. Manual application or continuous dripping can effectively reduce friction, prevent aluminum adhesion, and improve saw blade service life.
Aluminum alloy sawing is a technically demanding processing process. Only with scientific and reasonable operation methods and equipment configuration can efficient, safe, and high-quality processing goals be achieved. In the future, with the continuous emergence of new materials and new technologies, aluminum alloy processing technology will also usher in a broader development space.
