Mastering Metal Notching Techniques: A Comprehensive Guide

Metal notching is the fabrication technique of removing unwanted metal from the perimeter of metal sheets or plates, giving them the desired shape. Whether it’s creating slots, grooves, or intricate designs, metal notching is used, and every metal fabricator, artisan, and manufacturer should be aware of the nuances of the technique.

Until then, please read this blog, where we have discussed the intricacies of metal notching, the difference between metal punching and notching, equipment selection, its applications, and other important concepts. Read on.

Understanding Metal Notching

Notching is the method of removing excess metal from metal sheets or plates to create specific shapes and patterns. Multiple techniques and tools are utilized, including manual tools such as hand notchers, power tools like hydraulic notchers, or CNC (Computer Numerical Control) machines for automated precision.

Exploring Metal Punching

Metal punching is another technique for creating patterns, holes, and distinct shapes within the perimeter of sheet metal or plates. It uses a punch and die set to achieve the goal. Punching is typically performed with a hydraulic or mechanical press, where the punch exerts force on the metal workpiece to produce the desired cutout.

Comparing Notching and Punching

While notching and punching are used to create holes and shapes in metal sheets and plates, their applications and outcomes are entirely different. Notching is primarily used to develop notches, grooves, or slots along the edge or surface of a workpiece while punching is focused on creating holes or cutouts. A suitable metal fabrication technique is used based on the project’s requirements.

Choosing The Right Equipment

Metal punching tools make this process indispensable. Here is a guide on choosing the right equipment for metal punching and notching operations.

Consider the capacity

Ironworkers are chosen by their tonnage capacity. The heavier the punch, the cleaner the hole. Whether you’re punching metal or notching, the first step towards choosing the right equipment is to determine the kind of project you undertake. For industrial projects, you need heavier machines.

At New Mexico Metals LLC, we use a GEKA Bendicrop 60S Universal Ironworker for our processes, which delivers cleaner and more precise holes.

Versatility Needs

Every metal is different, but you can only choose distinct equipment for some metals. It would help if you chose a machine made for versatile hole punching and notching. This is one of the most important considerations when choosing the right equipment.

Safety Issues

When choosing a metal notching machine, consider the safety guidelines. During a metal notching operation on sheet metal, one is prone to injuries when overlooking safety issues. The machine should be equipped with adjustable stroke control to avoid any accidents.

Metal punching and notching can be overwhelming, especially if you are a beginner trying it for the first time.

So, choose an expert like New Mexico Metals LLC in Albuquerque and entrust us with your metal punching requirements for quality metal works.

Best Practices for Metal Notching and Punching

These best practices must be followed during metal notching operation in sheet metal to ensure quality results:

  • Measure and mark the metal accurately before punching and notching. This is optional when using CNC machines, considering automated machines map the metal accurately and repeatedly.
  • Clamps are essential for the job. Secure the metal piece firmly to prevent it from moving during the operation.
  • Choose the right equipment based on the size of the operation.
  • Use coolants, if required, to ensure cleaner and smoother edges. Reducing the wear and tear of the punching and notching tools is also important.
  • Effective quality control policies should be in place. The completed workpieces must be inspected thoroughly to ensure quality results.
