CNC numerical control cutting aluminum sheet, the efficient tool of modern manufacturing



In modern manufacturing, aluminum sheets are widely used, and CNC (Computer Numerical Control) cutting technology has become an efficient tool for processing aluminum sheets. CNC cutting aluminum sheet technology relies on its high precision, efficiency, and flexibility, and has been widely applied in various industries. This article will delve into CNC cutting aluminum sheet technology, its advantages, applications, and its significance in modern manufacturing.

What is CNC Cutting Aluminum Sheet Technology?

CNC cutting aluminum sheet technology is an automated numerical control processing technique that precisely cuts aluminum sheets through computer programs to achieve complex shapes and high precision cutting. CNC cutting machines employ different methods like tungsten inert gas cutting, laser cutting, or plasma cutting to efficiently process aluminum sheets with high automation and intelligence.

Cutting CNC Techniques for Aluminum Alloy Sheets:

Use suitable CNC machine tools and cutting tools. Cutting aluminum alloy requires higher spindle speeds and lower feed rates compared to cutting steel. Your CNC machine tool needs to have enough rigidity to withstand the cutting force of aluminum. Cobalt steel cutting tools are most suitable for stainless steel.

Secure the aluminum alloy sheet properly. Compared to other metals, aluminum alloy generates more vibration and shaking during processing. Use fixtures, mechanical devices, or vacuum suction to securely fix the sheet. If possible, apply tension to prevent vibration.


Use appropriate feed rates and spindle speeds. For a 1/4-inch end mill, the typical spindle speed range is 15,000-20,000rpm, and the feed rate is 8-12ipm. Too slow can cause chip buildup on the tool, while too fast can lead to premature tool wear. Start with conservative values and gradually increase until optimal.


Use compressed air to blow away chips. If chips accumulate in the cutting path, it may re-cut the workpiece. Use compressed air to blow away chips regularly. Before restarting the program, use a brush to clear any chips on the workpiece surface.


Prepare the workpiece surface. Wipe with solvent to remove any oil stains, dirt, or oxide layers before processing. This can achieve better cutting results and avoid contaminating the workpiece.

Use lubricants/coolants. Aluminum alloy quickly generates heat. Spraying lubricants or coolants can help dissipate heat, prevent chip welding, and prolong tool life.


Take light cutting and multiple-layer cutting. Adopt shallower cutting to limit the tool load. Avoid cutting to full depth in a single pass, allowing intermittent cutting for heat dissipation.


Regularly check the cutting tools. The soft nature of aluminum alloy can quickly wear out cutting tools. Check for any chips, buildup, or wear on the tools, and replace them as necessary. Be careful when tightening the tools to prevent loosening.

Advantages of CNC Cutting Aluminum Sheet Technology:

High Precision: CNC cutting technology allows precise control of the cutting equipment's movements, achieving sub-millimeter cutting precision, ensuring the machining quality of aluminum sheets.


High Efficiency: CNC cutting aluminum sheet technology can achieve continuous high-speed cutting, saving a considerable amount of labor and time costs, and enhancing production efficiency.


Flexibility: CNC cutting technology can flexibly adapt to various product requirements, suitable for producing aluminum sheets of different shapes and sizes.


Waste Reduction: CNC cutting technology maximizes the utilization of aluminum sheet materials, reducing waste and lowering production costs.
