The right choice of steel processing technology has a direct impact on the quality, durability and cost-effectiveness of the finished components. At RADMOT, we understand how important it is to manufacture steel components with precision – regardless of the sector for which they are intended. Below, we explain how different processing methods affect the strength of the steel and dimensional accuracy.
The choice of the appropriate steel machining method should be based on an analysis of several factors: the type of material, the required tolerances, the batch size and the end use. At RADMOT, we use both turning and steel milling, as well as finishing processes such as grinding – selecting the technology in each case based on cutting parameters and the intended function of the component.
CNC milling enables the production of parts with complex geometries and high repeatability. The high-end milling centres in our machine park allow us to achieve tolerances as tight as IT6. Professional CNC milling – check out our services if you are looking for stable series production with guaranteed quality.
Precision CNC turning – see what we offer if your priority is high-precision cylindrical components with low unit costs – this applies, for example, to production for sectors such as mechanical engineering and automation or electrical engineering.
The type of steel being machined is crucial for selecting the right technology. Mild steels have good machinability but are prone to deformation during machining and cooling. They require precise selection of cutting parameters and thermal control of the process, particularly for thin-walled components.
In contrast, hardened steel with a hardness of 50–60 HRC poses a challenge for both tools and machines. At RADMOT, we use carbide tools and optimised machining strategies, enabling us to work effectively with hardened surfaces. This approach is particularly effective in the automotive sector and the medical industry, where wear resistance and component durability are of paramount importance.
CNC coolants play a vital role in the machining process – not only do they cool the cutting zone, but they also minimise friction, remove chips and extend tool life. Their correct selection directly influences the dimensional accuracy of the steel and surface quality.
At RADMOT, we use coolants that comply with the latest environmental and technological standards. This helps to reduce the formation of micro-cracks and thermal deformation, which is particularly important during milling and finishing steel turning, especially of thin-walled components. As a RADMOT expert explains, a properly selected coolant can improve machining quality just as effectively as advanced CNC control.
In the case of hardened steel or high-precision components, non-emulsifying oil cooling or high-pressure coolant delivery may also be used – this translates into better control over the final quality, particularly in applications requiring high dimensional stability, such as electrical engineering or the medical industry.
Heat treatment is a crucial stage in the production of steel components subjected to high mechanical loads, abrasion or temperature fluctuations. Processes such as hardening, tempering and nitriding significantly affect the steel’s final strength, hardness and service life. In industries such as the automotive, aerospace and consumer products sectors, this is often a prerequisite for meeting quality standards.
A typical process sequence may first involve rough machining (e.g. turning or milling), followed by heat treatment, and finally finishing operations such as grinding or lapping. This sequence of operations helps to minimise the risk of deformation and achieve high dimensional stability in the finished component.
Proper planning of this stage – taking into account the material, the component’s geometry, steel cutting parameters and the intended application – is essential when designing an optimal manufacturing process.
Minimising stress and distortion is one of the keys to success in the production of precision components. Even minor errors in planning CNC steel machining can result in workpiece deformation, which leads to increased costs or the need for rework.
The most commonly used approaches include:
Extensive measurement facilities, such as those available at RADMOT, allow us to effectively control quality right from the production stage, rather than only at final acceptance. In the case of very high-precision components used, for example, in the medical industry, this approach is crucial for the reliability of the final product.
