How to Tap Aluminum Extrusion?

Aluminum extrusion is a popular manufacturing technique used to create a wide range of products. One of the key steps in the manufacturing process is tapping, which involves creating internal threads in the extruded aluminum. In this article, we’ll discuss the steps involved in tapping aluminum extrusion and some important considerations to keep in mind.

Step 1: Choose the Right Tapping Tool

Before you can begin tapping aluminum extrusion, you’ll need to choose the right tapping tool. There are a few different types of taps that can be used for this purpose, including hand taps, machine taps, and spiral point taps. Hand taps are the most common type of tap used for tapping aluminum extrusion, as they are easy to use and require minimal setup.

When choosing a hand tap, it’s important to consider the diameter and pitch of the thread that you need to create. You should also choose a tap with a sharp cutting edge, as this will help to ensure a clean and accurate cut.

Step 2: Prepare the Aluminum Extrusion

Once you have your tapping tool, you’ll need to prepare the aluminum extrusion for tapping. Start by measuring and marking the location where you want to create the internal threads. Then, use a center punch or other tool to create a small divot in the center of the mark. This will help to guide the tap and ensure that it stays centered during the tapping process.

Step 3: Begin Tapping

With the aluminum extrusion prepared, it’s time to begin tapping. Insert the tap into the hole that you created in step 2 and begin turning it clockwise. Apply a moderate amount of pressure as you turn the tap, but be careful not to force it too hard, as this can cause the tap to break.

As you turn the tap, it will begin to cut into the aluminum and create the internal threads. Continue turning the tap until you have created the desired depth of thread.

Step 4: Clean the Tap

After you have finished tapping the aluminum extrusion, it’s important to clean the tap to remove any metal shavings or debris. Use a brush or other tool to carefully remove any debris from the cutting edges of the tap. You can also use a lubricant or cutting oil to help remove any debris and protect the tap from wear and tear.

Step 5: Inspect the Threads

Once you have finished tapping the aluminum extrusion and cleaned the tap, it’s important to inspect the threads to ensure that they are clean and accurate. Use a thread gauge or other tool to check the diameter and pitch of the threads. If necessary, you can use a thread chaser or other tool to clean up any rough edges or imperfections in the threads.

Benefits of Tapping Aluminum Extrusion

Tapping aluminum extrusion offers a number of benefits, including:

– Increased versatility: Tapping allows you to create internal threads in aluminum extrusion, making it easier to attach other components or create a secure connection.
– Improved strength: By tapping the aluminum extrusion, you create a stronger and more secure connection than you would with other attachment methods.
– Cost-effective: Tapping is a relatively simple and cost-effective process, making it a popular manufacturing technique for a wide range of products.

Tapping Aluminum Extrusion vs. Other Attachment Methods

While tapping is a popular attachment method for aluminum extrusion, there are other methods that can be used as well. Some of these methods include:

– Welding: Welding can be used to attach aluminum extrusion components together, but it requires specialized equipment and can be more time-consuming and expensive than tapping.
– Adhesive bonding: Adhesive bonding can be a good option for attaching aluminum extrusion components, but it may not be as strong or secure as tapping.
– Mechanical fasteners: Mechanical fasteners such as screws or bolts can be used to attach aluminum extrusion components together, but they may be less secure than tapping and can add extra weight to the product.

Conclusion

Tapping aluminum extrusion is a cost-effective and versatile manufacturing technique that allows you to create internal threads in aluminum extrusion. By following the steps outlined in this article, you can tap aluminum extrusion with ease and confidence. With the right tapping tool and a little bit of practice, you can create strong and secure connections that will stand up to the test of time.
