Surface treatments in production Definition, process and
the importance of trays

Introduction

Surface treatment is an essential part of modern production technology. Various processing methods can be used to optimize the external appearance of a workpiece to make it more resistant, more precise or more aesthetically pleasing. From the automotive industry to aerospace and medical technology: surface treatments are used in almost all industries.

But how do surface treatments relate to workpiece carriers and why do workpiece carriers play such an important role in the quality assurance and efficiency of machining processes? In this article, we will look at the most important surface treatment processes and the advantages of workpiece carriers in this context.

What is a surface treatment?

Surface treatment describes the processing of the outer layer of a workpiece in order to change or improve its properties. Depending on the process, the surface can be made harder, smoother, more corrosion-resistant or more visually appealing.

Objectives of surface treatment

The surface treatment is carried out in order to:

  • To increase the durability of the workpiece (protection against wear and corrosion).
  • Improve friction properties (important for moving parts).
  • To increase optical quality (important in consumer goods production and medical technology).
  • Optimize functionality (e.g. for mechanical components with precise surface requirements)

Why is surface treatment important?

The surface quality of a workpiece has a significant influence on its performance and service life. An inadequately treated surface can corrode more quickly, fail to withstand mechanical stress or wear out more quickly due to friction. Surface treatments help to overcome these challenges and ensure that workpieces reliably fulfill their intended purpose over the long term.

Why is surface treatment important for my industry?
Surface treatments are indispensable in many industries as they increase the service life and performance of components. In the automotive, medical and aerospace industries in particular, they ensure the necessary precision and reliability.

How do I choose the right process?
The choice of the right process depends on the material of the workpiece, the application and the required surface properties. For example, honing or grinding is often used for precision components, while polishing is preferred for decorative surfaces.

The most important procedures

1. honing: Precision through cross grinding

Honing is an ultra-fine machining process that is used specifically to improve the dimensional accuracy and surface quality of cylindrical components. It is particularly often used in the manufacture of cylinder liners in engines or hydraulic systems.

Advantages of honing:

  • High-precision surface structure: The cross-grinding that occurs during honing improves the lubrication properties and contributes to the longevity of the components.
  • Minimal material removal: The process enables extremely precise processing with minimal material loss.

Question: How can honing improve the quality of my product?

Honing improves the dimensional accuracy and surface structure of cylindrical components, resulting in better performance and a longer service life. This is particularly important in the automotive and mechanical engineering industries in order to minimize friction and wear.

2. polishing: Gloss and smoothness

Polishing is a surface treatment in which a smooth and shiny surface is produced by mechanical or chemical removal of material. It is often used for decorative or hygienic applications, for example in medical technology or the food industry.

Advantages of polishing:

  • Improved aesthetics: Polished surfaces not only look attractive, they are also smoother and more resistant to dirt and corrosion.
  • Hygienic advantages: In sectors such as the food and pharmaceutical industries, polishing contributes to easier cleaning and sterilization.

Question: In which sectors is polishing particularly important?

Polishing is particularly important in medical technology, aerospace and jewelry manufacturing, as it offers both aesthetic and functional benefits, such as improved cleaning and corrosion resistance.

3. milling: Versatile material processing

Milling is a machining process in which material is removed using a rotating cutting tool. It is used to carve complex shapes and structures into the workpiece.

Advantages of milling:

  • High flexibility: Milling can be used for a wide range of materials and geometries.
  • Precision: High-precision components can be manufactured using modern CNC milling machines.

Question: When should I choose milling instead of other machining methods?

Milling is ideal when complex geometries or special shapes need to be created. It is suitable for a wide range of materials, including metals, plastics and composite materials.

Other important surface treatment processes

4. grinding

Grinding is a fine machining process in which material is removed from the workpiece surface using rotating grinding wheels. It serves to improve the surface quality and is often used after coarser machining steps such as milling.

5. lapping

Lapping is a precision machining process used to achieve extremely smooth surfaces. A mixture of abrasives and liquid is pressed between two surfaces to remove material evenly.

6. anodizing

Anodizing is an electrochemical process that is mainly used for aluminium. It strengthens the oxide layer on the surface and thus increases corrosion resistance and hardness.

The importance of workpiece carriers
for surfaces

Now that we have looked at the most important surface treatment processes, the question arises: What role do workpiece carriers play? Workpiece carriers are essential for the precise and secure positioning of components during the machining process. They ensure that the workpiece remains stable and securely fixed during the entire machining process, which is crucial for the quality of the surface treatment.

Why are workpiece carriers so important?

Workpiece carriers offer several decisive advantages for surface processing:

1. secure fixation

During surface treatment processes such as polishing, honing or milling, the workpiece must be held in an exact position to ensure uniform processing. Workpiece carriers ensure that no movements or vibrations affect the result.

2. improved processing quality

The stable fixation prevents surface defects such as scratches or irregularities. This leads to a higher surface quality and increases the service life of the machined workpiece.

Question: Can a workpiece carrier improve material flow and efficiency?

Workpiece carriers can significantly speed up the production process by positioning the workpiece quickly and precisely and supporting the automated material flow.

3. automation and efficiency

In modern manufacturing, many surface treatment processes are automated. Workpiece carriers enable seamless integration into automated systems and help to increase processing speed and efficiency.

4. protection of the workpiece

Workpiece carriers minimize the risk of damage or deformation during processing. This is particularly important when it comes to sensitive or expensive workpieces that require high precision.

5. repeatability

In series production, every workpiece must be processed in exactly the same way. Workpiece carriers ensure repeat accuracy by positioning the workpiece precisely at each processing stage.

Conclusion

Surface treatment is an essential step in production that has a significant impact on the functionality, durability and aesthetics of components. Workpiece carriers play a central role in this process, as they not only ensure machining quality, but also make the entire production process more efficient and precise.
