Metal Processing Techniques: An Overview and Their Applications

Metal processing techniques form the backbone of numerous industries. Nearly every sector utilizes metal materials or tools from manufacturing to construction, making these techniques crucial. This article offers a detailed insight into the diversity of metal processing methods and guidance on choosing the best one to fit your needs.

Understanding Metal Processing

In essence, metal processing involves dividing a metal workpiece into various parts using force or erosion techniques. Cutting actions can be generated using different methods ranging from blades to electrical discharges and the remarkable force of waterjets.

The Genesis of Metal Processing

The roots of metal processing trace back to ancient civilisations like the Egyptians. However, it was Henry Maudslay who invented notable processes like the lathe. Over the years, advancements such as electrical components and CNC technology have continued to refine and automate these processes.

The Purpose of Metal Processing

Metal processing is a vital step in raw material manipulation. Techniques like waterjet cutting, for instance, are advanced enough to create a finished product directly from raw metal sheets and blocks, bypassing several manufacturing steps.

Diverse Metal Processing Methods

Metal processing techniques are numerous, but they primarily fall under mechanical, abrasive, and thermal cutting.

Mechanical Cutting

Mechanical cutting involves a sharp tool against the metal, producing waste material. Notable mechanical cutting methods include turning, milling, drilling, sawing, shearing, and punching. Each of these methods comes with their own set of advantages, disadvantages, and suitable applications.

Abrasive Cutting

Abrasive cutting hinges on friction instead of force or sharp edges. Waterjet cutting is a premier example of abrasive cutting. By leveraging the force of highly pressurized water, it erodes metal particles and creates precise cuts in linear, non-linear, and internal patterns on the workpiece. Despite requiring a skilled operator, waterjet cutting is favoured for its high precision, minimal material wastage, and superior edge quality.

Thermal Cutting

Thermal cutting melts the metal material at the required location. Techniques under this category include laser cutting, plasma cutting, and oxy-fuel cutting. While these methods offer precision, they may also create heat-affected zones that can compromise the integrity of the workpiece.

Electrical and Electrochemical Techniques

Electrical Discharge Machining (EDM) melts metal through electric arcs without direct physical contact, making it suitable for creating non-linear cuts in conductive materials. In contrast, Electrochemical Machining leverages electricity and chemical reactions to remove the workpiece material, excelling at working with high hardness metals.

Choosing the Right Metal Processing Technique

Selecting the appropriate metal processing method should be done after evaluating factors like material type, required precision, production volume, cost, finishing requirements, operator skill requirement, and environmental impact, among others.

Wrap Up

A reliable metal processing machine can mean the difference between a quality outcome and a pile of discarded parts. Waterjet machines have revolutionized metal processing, offering the capability to handle almost any thickness and produce finished parts without additional processing steps.
