Stainless steel is a hard metal. Its many grades and types make it a complex metal requiring special techniques and tools for forming and punching. The pros of stainless steel, such as its corrosion resistance and exceptional strength, make it a difficult material to work with, especially during punching.

Punching requires a thorough understanding of the metal to ensure it is punched without compromising its structural integrity or appearance. At New Mexico Metals LLC, we know it, and thus, we have shared in this blog why special techniques are required for punching stainless steel.

Read on for the details!

Understanding Stainless Steel

A clear understanding of the metal is essential for effective punching.

Stainless steel is an aesthetically pleasing metal known for its tensile strength and corrosion resistance. It can be as hard as iron but as malleable as aluminum, depending on its composition.

The hard nature of the metal makes it ideal for use in construction, medical, automotive, and other industries, but it also increases the risk of cracking or deformation during punching.

It requires greater force and sharper tools to achieve clean results. Thus, punching stainless steel involves more than just pressing a hole.

What is Punching in Metalwork?

Meal punching is the art of punching holes of distinct shapes within the perimeter of the sheet metal or pipes using a punch and die set. The punch applies shear force on the metal underneath and pushes out the unwanted metal piece, leaving a clean hole.

The technique is used in multiple industries to create slots, holes, or patterns in metal parts, prepare material for bolts, rivets, or fasteners, produce electrical panels or enclosures, precision forming, etc.

What Are The Challenges of Punching Stainless Steel?

There are multiple challenges that everyone faces while punching stainless steel, which are discussed below:

Material Hardness

Stainless steel can be very hard, requiring a higher tonnage to carve clean holes or shapes through the metal. Using standard tools means that the tools wear out faster, leading to rough edges.

Tool Wear and Tear

Stainless steel punching tools are often prone to quick wear and tear due to the abrasive nature of the metal. It can lead to inconsistent holes, burrs, rough edges, and tool failure. Thus, HSS or coated carbide punches are required for steel.

Heat Buildup

Punching generates heat, and stainless steel retains the heat for a long time. It leads to metal becoming even tougher and, thus, difficult to work with.

Spring-Back Effect

Due to its elasticity, stainless steel springs back after punching. It can affect dimensional accuracy, especially in metal forming and punching tasks that require tight tolerances.

Whether a DIYer or a metal professional, you must avoid these challenges by relying on expert metal punching services.

Specialized Techniques for Punching Stainless Steel

At New Mexico Metals LLC, we use specialized techniques to punch stainless steel, which are discussed below:

Tooling Selection

Our tooling selection succeeds in material inspection, allowing us to understand which punching coating or punch and die machine is right for the operation. Appropriate coatings like titanium nitride help reduce friction and wear. Also, it has the tools to remain sharp for a longer time.

Optimized Punch and Die Clearance

Proper clearance between the punch and die is required; otherwise, the edges can be burred, and you might end up with misshapen holes. Punch and die clearance is the difference between the punch and the die when they hit and remove the metal. This clearance depends on the metal thickness and hardness. Too little clearance can result in burrs and galling. For stainless steel, a slightly increased clearance is used.

Controlled Speed

Rather than using fast, high-impact motions, a slower and steady force is required to cleanly remove the slug. It improves accuracy and minimizes heat and distortion.

Lubrication

Friction and heat must be controlled during punching; thus, an effective lubricant is needed. It ensures smoother motion during punching and also controls heat levels.

What is Sheet Metal Notching?

The sheet metal notching process involves removing material from the sheet’s edge. It involves creating custom designs on the perimeter, creating rounded edges, or cutting the metal in any way that would serve the project’s purpose.

Sounds easy? It is, if you have the right tools, materials, and machines.

Here are some of the key items that help achieve the best notching results:

Sheet Metal: As the operation is performed on sheet metal, its presence is mandatory for the operation. However, it is crucial to choose the right material, as the project’s success depends significantly on this particular choice.

Metal Notcher: A metal notcher is any tool that helps notch the material. It is designed to cut precise notches on the sheet. For smaller notching jobs, manual notchers are a popular option. These are also available in powered options.

Safety Gear: Safety gear is a must for any metal-related operation, considering the nature of the job. The flying debris, the dust, the noise, etc., all of these impact your health, and thus, you need safety gear. It includes hand gloves, safety glasses, ear muffs, etc.

As a DIYer, you need not invest in all these tools, because you might not have a long-term use of the tools. It is advised to seek professional help to ensure your safety.

Steps to Achieve Perfect Sheet Metal Notching

Check out these essential steps to achieve perfection in any sheet metal notching operation:

Preparation and Measurement

The first step is to prepare the sheet metal for the operation. Thus, you should take a ruler or measuring tape and mark where notches will be created. Double-check measurements to ensure accuracy, as precise marking is crucial for achieving clean cuts.

In manual operations, notching is normally achieved without any additional tools. Thus, the need to secure the sheet metal is much more than the automated operations. Ensuring stability prevents unnecessary movement during the notching process, which could lead to inaccuracies.

Set Up The Metal Notcher

This step is not necessary, especially if you are undertaking a small notching job with a manual notcher. These are quite straightforward to use and need not require setting up.

The step is crucial where powered notchers are required. Depending on the machines, you must adjust the cutting blades or guides to match the width and depth of the notch needed.

If you use a CNC or another automated advanced technology, the machine shall determine the measurements.

Make the Notch

Once the machine is prepared, it is time to align the sheet metal. Position the marked notch lines under the cutting head or blade of the metal notcher. Ensure the sheet metal is aligned properly to avoid crooked or off-center cuts. Activate the sheet metal notching tool and allow it to notch the sheet metal.

Some metal notchers have a lever or a hand crank that requires pulling to activate the notch. Depending on the machine you have, activate the notcher.

The story of manual notchers is different. You must apply steady pressure for every notch to achieve perfection. One deformation can render the entire sheet useless.

Inspecting and Finishing

After every notching job, no matter how small it is, carefully inspect the edges and corners for any imperfections or burrs. Use deburring tools or sandpaper to smooth out rough edges, ensuring a clean finish.

For large-scale operations, a test fit is recommended. Test the notched sheet metal piece into its intended place and check the fit. If any adjustments are required, make them.

Is Sheet Metal Notching Right For You To Attempt?

If you are a professional, you can follow the abovementioned steps and achieve perfection.

However, if you are a DIYer, it is wise to consult a professional for a notching job. Multiple aspects of notching should be considered before you attempt it.
