Mechanical processing is essential in modern industry. However, it’s not just about using cutting-edge machinery. It requires technique, sophisticated tools, and a touch of craftsmanship. Brass, an alloy of copper and zinc, is one of the most commonly processed materials. This is due to its versatility, strength, and adaptability in various industrial contexts. Nonetheless, working with it effectively demands experience and a keen eye for detail.

What is mechanical processing?

Mechanical processing is the method by which raw materials, such as metals and alloys, are shaped into components with precise forms.
The main techniques in mechanical processing include:

  • Turning: used to create cylindrical surfaces and threads.
  • Milling: to shape flat surfaces and complex forms.
  • Drilling and Threading: for secure and durable connections.

Many of these processes employ CNC (Computer Numerical Control) machines, ensuring extreme precision. In sectors such as automotive and thermohydraulics, these technologies are used to produce essential components like valves and connectors.

Why choose brass?

Brass is often chosen because it is a relatively soft material, making it easy to work with while remaining durable and resistant. Additionally, it is highly resistant to corrosion, a crucial detail for applications in humid environments or those in contact with fluids. The strengths of brass include:

  • Ductility: soft and easy to process.
  • Strength: withstands stress effectively.
  • Conductivity: ideal for heat and electricity.
  • Aesthetic Appeal: its golden shine makes it perfect for decorative purposes.

Thanks to these qualities, brass is used in industries ranging from thermohydraulics (fittings and valves) to automotive (electrical connectors), and even design.

Techniques for processing brass

Working with brass requires precision and the use of specific techniques, each with a distinct goal. The most common ones include:

  • Turning: a fundamental process for manufacturing fittings and valves, widely used in the thermohydraulic sector.
  • Milling: ideal for obtaining flat surfaces or complex shapes, often required for automotive components.
  • Drilling and Threading: essential for creating reliable and robust connections, particularly in hydraulic and electrical systems.

To produce many industrial components, brass is often processed through hot stamping or shell casting. Hot stamping allows for the creation of solid, durable shapes, ideal for parts that must withstand high pressures. Shell casting, on the other hand, is an excellent choice for producing more complex geometries, ensuring both precision and quality.
When used correctly, these techniques maximize the properties of brass, making it a versatile and indispensable material across many industries.

The Value of Human Expertise

Despite the efficiency of machines, the skill of an expert technician is irreplaceable. A technician can calibrate tools, select the right parameters, and monitor each stage of the process. They also know how to adapt to any variations in the properties of brass from one batch to another. In highly sensitive sectors such as automotive, even a small imperfection can make a significant difference.

The importance of maintenance

To ensure quality processing, machinery must always be in perfect condition. Here are some fundamental practices:

  • Tool inspection and replacement: To avoid imprecise processing.
  • Lubrication of moving parts: To reduce friction and prevent breakdowns.
  • CNC software updates: To handle complex processing with the latest technologies.

Maintenance not only improves product quality but also reduces downtime and costs.

Practical applications of brass

Brass is an indispensable material in various sectors:

  • Automotive: used for electrical connectors, valves, and fluid dynamics components, thanks to its resistance to high temperatures and corrosion.
  • Thermohydraulics: ideal for valves and fittings due to its resistance to humidity and pressure.

Brass processing demonstrates how tradition and innovation can coexist. This ancient material remains an irreplaceable choice for modern industry.
