In the metalworking industry, there are parts for which the margin for error is minimal. When demanding geometries, tight tolerances and consistent production volumes are involved, CNC turning ceases to be merely a machining process and becomes a critical decision for project stability.
At ETMA, the Turning process is part of the 10 Integrated Production Processes system and is geared towards the manufacture of precision turned parts tailored to the client’s needs, with diameters ranging from 3 mm to 60 mm, supporting demanding technical requirements and controlled series production.
When the objective is to ensure precision parts with consistent performance throughout medium and large production runs, several factors make the difference. From the technical capability of the process to production control, including the equipment and materials used, each element contributes to the reliability of the final result. Let us therefore look at the main factors, while also highlighting the role of ETMA’s specialised technical team.
- WHEN DIMENSIONAL REQUIREMENTS LEAVE NO ROOM FOR IMPROVISATION
CNC turning is especially relevant when dealing with small parts with demanding technical requirements.
At ETMA, this process is applied to the manufacture of components in which precision and repeatability are decisive for final performance, such as:
- parts for injectors, bushes, compression limiters, shafts, spacers and rings.
This capability also extends to product types such as:
- precision shafts and micro-shafts, bushes, technical sleeves and spacers, functional threaded components, cylindrical parts with multiple diameters, and complex components for mechanical subassemblies.
It is this specialisation in small and technically challenging parts that enables ETMA to operate with confidence in projects where dimensional accuracy is critical.
- A PROCESS DESIGNED FOR SMALL PARTS WITH A HIGH DEGREE OF COMPLEXITY
At ETMA, turning is not approached in a generic way. It is geared towards small parts with demanding technical requirements, which implies strict control over geometry, repeatability and process behaviour in an industrial environment.
This is precisely where accumulated know-how makes the difference: it is not simply a matter of manufacturing a part according to drawing, but of ensuring that such conformity is maintained consistently throughout medium and large production runs. This positioning is aligned with the way the company presents itself: a focus on small to medium-sized parts, with precision and reliability, and technical support from the project stage through to the final product.
- A TECHNOLOGICAL BASE TAILORED TO PROCESS ROBUSTNESS
ETMA’s response capability in CNC turning is supported by a diversified equipment base tailored to the requirements of precision turned parts for medium and large production runs. Among the main resources available are:
- Mono-spindle automatic lathes and fixed and sliding headstock CNC lathes (Swiss-type turning), such as CNC DECO 26a, DECO 20, Tornos DELTA20, Index G200, Ergomat Traub TND 65, TD26, Muratec MW 35 and Muratec MW 50.
ETMA also has:
- Multi-spindle automatic lathes and 6-spindle CNC lathes, namely Gildmeister GMC35 ISM, GM-16, AS-16 and AS-20, as well as 9-station transfer machines, such as the Variomatic T3, and pallet-changing machining centres, such as the Fanuc Robotdrill T14ia.
This technological base makes it possible to respond more robustly to demanding geometries, consistent production volumes, and high repeatability and process stability requirements.
- RAW MATERIAL, PROCESS AND APPLICATION MUST BE ALIGNED
Another decisive factor lies in the compatibility between the material, the geometry and the functional requirements of the part. At ETMA, the Turning process works with different forms of raw material, namely slugs, bars and tubes, depending on the requirements of each project. The materials processed include:
- carbon steels and alloy steels, stainless steels, aluminium and aluminium alloys, brass, copper and other metallic materials under technical specification.
This diversity allows greater flexibility in responding to different industrial applications, ensuring that the production solution is technically suited to the context of use, the expected performance and the client’s requirements.
But the real added value lies not only in the variety of raw materials: it lies in the ability to transform them into parts with predictable behaviour, suited to the sector, the function and the context of use.
When the client is looking for a reliable solution, they are not merely looking for a machined part — they are looking for a process capable of technically responding to what that part will be required to do in service.
- SERIES PRODUCTION REQUIRES MORE THAN CAPACITY: IT REQUIRES CONTROL
A technically sound part in a first sample is not enough. In medium and large production runs, the real challenge lies in maintaining the same level of quality over time, across batches and under higher volumes.
This is where ETMA’s integrated approach becomes especially relevant. By operating with a vertically integrated production model and 10 Integrated Production Processes, the company reinforces control over the various stages of the production chain, reduces external dependencies and improves responsiveness, traceability and final consistency
For the client, this translates into greater industrial predictability, greater process stability and lower risk throughout production.
CONCLUSION
What, then, makes ETMA’s CNC turning a reliable solution for medium and large production runs? The answer lies in the combination of precision, technological suitability, technical competence, process control and production integration.
When these factors work together, turning ceases to be merely a manufacturing operation and becomes a robust industrial response, prepared to transform demanding requirements into consistent results.
At ETMA, more than manufacturing precision turned parts, the focus is on ensuring that each project meets the client’s needs with rigour — from the definition of the solution to stability in series production.
