CNC production with maximum precision

Surface treatment plays a decisive role in post-processing, as it influences the appearance, tolerances and functionality of the workpiece.

It is determined on the basis of the requirements of the end product, including aesthetic aspects, wear resistance and friction properties.

Techniques such as grinding, polishing and coating are used to achieve certain surface qualities. The choice of process depends on factors such as the material used, the required precision and the desired finish.

The complexity of the workpiece design is a decisive factor when choosing the appropriate CNC machining process. Turning isideal for rotationally symmetrical parts, while milling is better suited to complex geometries and parts with multiple planes or irregular shapes.

Complex designs may require the use of advanced 5-axis milling machines that allow simultaneous movements in five axes to machine intricate geometries in a single set-up. The choice of machining process is based on the ability of the process to produce the required geometry efficiently and to the required tolerances.

Thermal treatments such as hardening, tempering and normalizing can significantly change the mechanical properties of CNC-manufactured metal parts by altering the microstructure of the material.

Hardening processes increase the wear resistance and hardness of steel, for example, but can also lead to a reduction in toughness. Tempering is often carried out after hardening in order to restore toughness with slightly lower hardness.

These treatments allow engineers to tailor the material properties precisely to the respective application, but must be carefully planned to avoid undesirable stresses or deformations in the component.

CNC24 supports all common industry formats such as ST, STEP, STP, DWG and DXF as well as PDF, ZIP, XLS and CSV. Please contact us if you require further information on the file formats.

Machine calibration is of crucial importance for quality assurance in CNC production, as it ensures the accuracy and repeatability of machining processes.

A correctly calibrated machine ensures that the movements and positioning of the tools correspond exactly to the specifications of the G-code. Insufficient calibration can lead to deviations from the specifications, poor surface quality and, in the worst case, rejection of the manufactured part.

Regular calibrations, supported by precise measuring equipment and protocols, help to ensure that machine performance meets production standards.

Yes, through CNC24, customers can have custom-made precision parts manufactured that have complex geometries or special design requirements. The sourcing platform’s technology, including advanced CAD file analysis and AI-driven tools, enables the evaluation of complex designs and the identification of suitable manufacturing processes. Suppliers in the CNC24 network have diverse capabilities, including advanced machining and manufacturing technologies that enable them to meet a wide range of custom specifications and complex design challenges.

The choice of material has a significant influence on the programming of the G-code, as different materials require specific cutting speeds, feed rates and cooling requirements.

For example, harder materials such as titanium require lower cutting speeds and possibly special coolants to prevent overheating. In contrast, softer materials such as aluminum allow higher cutting speeds and feed rates.

These parameters must be precisely defined in the G-code in order to optimize the tool load and ensure a high surface quality and compliance with dimensional tolerances.
