The Evolving Precision of CNC Turning

Writer's picture: Louis DanielLouis Daniel

The implementation of CNC turning has brought about substantial changes in the manufacturing sector through the introduction of enhanced precision and complexity in the fabrication of machined components. As technology continues to advance, the future seems brighter for the deployment of more accurate applications across various sectors.



Exploring the Boundaries of Size via Nano and Micro Machining:

CNC turning is capable of manufacturing minuscule components that are measured in microns and have tolerances as low as 5 microns. Micro machining enables the production of extremely precise components, such as watch gears and medical devices, that are very small in size. 


In addition, emerging nano CNC technology will be capable of producing components at a microscopic scale, with tolerances that go below 1 micron. Applications encompass the fields of optics, electronics, and molecular-level surface changes. The specialised CNC machines needed are approaching the point where they can be commercially viable.


Adjusting to Challenging Substances:  

The range of materials suitable for precision CNC turning parts is likewise increasing. Recent advancements in machine rigidity, precise control of spindle speed, intelligent programming of toolpaths, and the development of specialised CNC equipment have made it possible to effectively perform turning and milling operations on these challenging-to-work-with materials. The applications encompass components for the aircraft industry, power production sector, and other high-stress applications.


Automating and Optimising Setups:

The productivity of CNC turning parts has been enhanced by the implementation of automation, which minimises the requirement for manual intervention. Bar feeders facilitate uninterrupted bar stock supply, allowing for unattended production operations. Automatic tool changers facilitate the exchange of tools as required throughout the machining process. Chip conveyors autonomously eliminate swarf without requiring manual intervention.


By integrating in-process inspection systems directly into CNC turning machines, faults can be promptly detected before further value is added. The use of this automated quality control system will lead to a significant enhancement in efficiency by reducing setup time and enhancing overall accuracy.


Acquiring Proficiency in Intricate Geometric Structures:

Advanced multi-axis turning centres have surpassed simple cylinder turning by excelling in the production of complicated asymmetric shapes, which were previously constrained by the latter. The ability to control numerous cutter axes simultaneously allows for the creation of contours that were previously unattainable.


Conclusion:

The ongoing advancements in multi-axis machine dynamics and five-axis CAM programming offer the potential for increased versatility in the creation of complex geometries, such as sculpted surfaces. The advancing CNC turning services from a renowned company like Createprorto Rapid System Limited will facilitate the use of smooth and organic shapes, which will be particularly advantageous for aerospace and medical implants.
