In Spain, more and more industrial companies are seeking precision turning companies capable of offering custom-made turned metal parts with very tight tolerances (±0.01 mm) and high production volumes with total repeatability.

What exactly does precision turning mean?

The term bar turning refers to automatic bar turning, a process in which the raw material (usually in the form of a metal bar) is continuously machined using automatic CNC lathes, producing turned parts with high dimensional accuracy.

Unlike other machining processes, bar turning is particularly optimised for:

• Medium and long series productions
• Small or micromechanical parts
• Components with complex geometries
• High standards of quality and repeatability

What is bar turning used for? Industrial applications

The precision bar turning service is used when the customer requires machined parts that guarantee:

• Consistent accuracy in large volumes
• Controlled surface finishes
• Automated and efficient production
• Manufacturing according to drawings or technical specifications

Some common examples of bar turning parts are:

• Components for locks and security systems
• Axles, pins and bushings
• Turned parts for medical systems
• Automotive components
• Industrial fasteners and assembly components

What are the most common machining processes?

There are several key processes involved in the manufacture of metal parts. The three most common are:

1. Turning

Process in which the workpiece rotates while a tool removes material.
It is the basis of precision bar turning and turning.

2. Milling

The tool rotates and the workpiece remains stationary.
It is used for prismatic geometries or flat surfaces.

3. Rectification

Finishing process to achieve extremely high tolerances and improve surface quality.

Bar turning mainly combines automatic CNC turning, although it can incorporate secondary operations such as milling, drilling or threading.

What is machining roughing?

Roughing is the initial phase of machining, where most of the material is removed to approximate the final shape of the part.
In small part machining processes, roughing must be perfectly controlled to avoid internal stresses or deformations, which is especially critical in precision parts.

Is milling the same as turning?

No. Although both are CNC machining processes, they have clear differences:

• Turning: the workpiece rotates → ideal for revolving parts
• Milling: the tool rotates → ideal for flat or complex surfaces

CNC bar turning is primarily based on automatic turning, optimised for assembly-line production.

Difference between precision turning and CNC machining

One of the most common questions is:
Are CNC turning and machining the same thing?

The short answer is: not exactly.

Although bar turning and CNC machining share similar technologies and principles, they are not exactly the same and respond to different production needs.

Bar turning is particularly specialised in the manufacture of small, high-precision parts, usually turned parts. This process is designed for assembly-line production, where large volumes with consistent repeatability are required. Automatic bar lathes are used for this purpose, allowing the part to be machined continuously from a metal bar, with a high level of automation and highly optimised cycle times.

CNC machining, on the other hand, is a broader concept that encompasses all types of parts, both small and large, simple and complex. It is used for short, medium and long runs, and employs a wide variety of machines, such as machining centres, CNC lathes, milling machines and multi-tasking machines. The level of automation can vary depending on the type of machine, the complexity of the part and the production volume.

Common materials in precision turning processes

Precision bar turning allows you to work with a wide variety of materials:

• Carbon steel
• Stainless steels
• Brass
• Aluminium
• Copper
• Special alloys

The choice of material depends on the end use of the part, the required tolerances and the industrial sector.

Types of machines used in bar turning

Lathes are at the heart of the process. The most commonly used are:

• CNC automatic lathes
• Sliding head lathes
• Multi-spindle lathes
• High-precision CNC lathes for metal

These machines allow multiple operations to be integrated into a single cycle, reducing time and costs.

In Dimeco They specialise in punching and profiling lines for the industrialised manufacture of metal parts. ‘At DIMECO, we offer solutions to metal parts manufacturers. We combine punching, forming, stamping and bending processes to guarantee high production volumes of parts with high-quality finishes.’

Our relationship with them

At Bianditz, experts in dies for punching and profiling lines, we have been manufacturing cutting dies for industrial lines for over 30 years. We also offer customised repair and maintenance solutions for existing dies.

“What stands out most about working with Bianditz is their quick response, adaptability, commitment to dealing with unforeseen circumstances, approachability and teamwork.” Josu Portilla (Mechanical fitter – specialising in line tuning).

Cutting Dies for industrial lines

Industrial punching and profiling lines require dies capable of working continuously, accurately and stably, even in high-volume production. In this type of environment, dies for industrial lines must not only guarantee the quality of the cut or punch, but also integrate perfectly into the line to avoid stoppages, deviations or defects in the final part.

In the case of DIMECO, its lines combine different operations, so dies for profiling lines play a key role in ensuring that each stage of the process maintains tolerances and repeatability.

Dies designed for punching and cutting metal

To respond to this type of line, at Bianditz we design and manufacture punching dies and cutting dies, adapted to the characteristics of each line and the material to be worked.

Specifically, we develop cutting dies for metal and punching dies for metal designed to work at high speeds, minimise wear and tear, and guarantee a long service life for the assembly.

Each die is adjusted to the geometry of the part, the thickness of the material and the production speed, ensuring a clean cut and precise punching even in demanding jobs.

In addition to punching and cutting, many industrial lines incorporate forming and bending operations. In these cases, we manufacture dies for sheet metal bending machines and dies for bending that allow these operations to be carried out within the line itself, maintaining process continuity.

Last Friday, we celebrated our 60th anniversary at our facilities in Irún, in an event that brought together around 90 people, including employees, customers, partners and institutional representatives.

During the day, there was a tour of the facilities and a screening of a commemorative video about the history of the company. This was followed by one of the most special moments, an interactive talk led by organisational psychologist Ángel Castrillo, who, together with representatives of the three generations of Bianditz, proposed a symbolic journey to Mount Bianditz, which gives the company its name.

Through this metaphor, the company’s past, present and future were reviewed: the difficulties faced by those who paved the way, the experience of those who are currently following in their footsteps, and the vision of those who will continue the climb. Javier Martínez, CEO of Bianditz Group, highlighted the importance of collaboration as a pillar for continued growth. He stressed that the future of the company depends on relying on a solid network of local partners, strengthening ties and generating shared value.

The event also included recognition for employees with more than 25 years of service and concluded with a relaxed gathering featuring music and catering.

The event was attended by the Mayor of Irún, Cristina Laborda, accompanied by the Deputy Mayor, Nuria Alzaga, and the Director of the Mayor’s Office, Mikel Huarte. Eva Fernández, Director General of Bidasoa Activa, also attended. Representing the Provincial Council of Gipuzkoa were Unai Andueza, Deputy for Economic Promotion and Strategic Projects; Amaia Arregi, Director General of Economic Promotion; and Xabier Iridoy, Director General of Innovation.

During the ceremony, the Mayor of Irún highlighted that ‘you have managed to convey very well who you are and what you do as a company,’ also emphasising ‘the challenge of continuity, generational change and deep roots’ as key elements of the project. For his part, Unai Andueza, Deputy for Economic Promotion and Strategic Projects, pointed out that “you have perfectly staged your trajectory. The first steps of the metallurgical tradition in this area can be seen in your history. That mountain, Bianditz, is an excellent metaphor for what you are today.”

At Cauchopren they are speacialist in the manufacture of technical moulded rubber and liquid silicone parts for applications in various industrial sectors.

“We have a close and strong relationship, we have been working together for many years

and we are very pleased with the service they provide us”.
— Etxahun Olaizola (Head of Cauchopren)

At Bianditz, experts in custom rubber injection and compression molds, we have been manufacturing injection, compression and rubber-metal moulds for Cauchopren for over 30 years. Most are molds for small rubber parts with complex geometries, usually with multiple cavities.

Además de la fabricación de moldes nuevos, para Cauchopren ofrecemos también soluciones personalizadas de reparación y mantenimiento de moldes ya existentes.

“In anticipation of our experience with Bianditz, I would highlight two aspects above all:
proximity and quality”.
— Etxahun Olaizola (Head of Cauchopren)

What their needs were and how we solved them

On this occasion, Cauchopren requested a customised rubber injection mold from us to produce bellows for control equipment. Our experience in similar projects enabled us to tackle the job with confidence and deliver a precise result. How did we do it?

• Mold design – mold manufacturing: based on the customer’s specifications, we design a 3D model. Once validated, we generate the 2D drawings to begin programming.

• CAM programming: after gathering the materials, we configure the CNC machine for manufacturing.
• Mold manufacturing: the mold undergoes various machining processes, such as milling, turning, erosion and blasting.
• Adjustment, assembly and control testing: we verify that everything is ready before delivering the final mold.

FINAL RESULT

These types of projects reinforce our position as a rubber mold manufacturer in Irún and as a supplier of customised rubber injection molds in Spain and the Basque Country.

At Bianditz, we continue to offer injection molding and compression molding tailored to each customer’s needs, providing customised industrial molds for rubber with the guarantee of a company with over three decades of experience.

At Bianditz, as injection mold makers and manufacturers of cutting and bending dies, we know that quality is not an option, but a requirement. Whether it is injection molds for rubber, metal or aluminium, or dies for punching, cutting or bending, every project must meet the highest standards before it leaves our premises.

Industrial molds for rubber and metal: control before delivery

Before any mold is delivered, we carry out a thorough check that allows us to guarantee its performance under real conditions. For some molds, we use a thermal verification system with BCR, where the mold is inserted into a specific part and oil is injected at 90°C for 2-3 days. This allows us to detect possible leaks, escapes or internal imperfections that could compromise production.

This procedure is particularly important in the manufacture of customised industrial rubber molds, where any deviation can affect the sealing, filling or durability of the final part.

Contact accuracy in dies and molds

In addition to the thermal test, we carry out a visual and mechanical check: we paint the base of the mold and join it to the upper part. If there are unpainted areas when separating them, we immediately detect the non-contact areas and adjust them to ensure the correct flow of material.

In the case of dies for profiling lines and dies for industrial lines, another method is used where precision in closing is key to obtaining clean cuts and accurate folds.
At Bianditz, control means attention to detail. That’s why our precision injection molds and dies come ready to integrate into demanding environments, with no margin for error.

At Bianditz, we continue to take firm steps towards a more responsible industry. As part of our commitment to sustainability, we have begun a process of reviewing and improving our packaging, with the aim of reducing the use of plastics and opting for more environmentally friendly materials.

Cardboard instead of plastic: a conscious choice

As part of this initiative, we have replaced plastic packaging with recyclable cardboard packaging for two key products in our tool range:

Magnetic nut setter
Plasterboard bit holder

Both products now come in new cardboard packaging, maintaining their functionality and protection, but with a much lower environmental impact. This improvement is not just about presentation, but represents a real commitment to reducing waste and facilitating recycling.

A further step in our commitment to the environment

Sustainability is not a one-off action, but a constant journey. We know that packaging is part of the product experience and also an opportunity to add value from an environmental perspective. At Bianditz, we will continue to incorporate improvements that allow us to reduce our footprint without compromising quality, because we believe that innovation must also look to the future of the planet.

At Bianditz we continue to be committed to solutions that facilitate the daily work of professionals. That is why we are launching the new ESTU cable ties (“Estu” means tighten in Basque), designed to offer a faster, safer and more efficient use experience in any work environment.

One of their great advantages is that they do not require scissors to cut: a twist of the wrist is all it takes to break them cleanly. This not only saves time, but also makes them a particularly practical option for work at height, electrical installations, gardening or any application where tools are not always at hand.

More comfortable, safer

Another of their special features is that, once cut, the edge remains blunt, avoiding possible cuts or snags. In addition to this improvement, they are highly heat-resistant, withstanding temperatures of between -10 °C and 70 °C, making them suitable for both indoor and outdoor use.

Built to last (and reuse)

ESTU cable ties are made of Nylon 66, a material recognised for its mechanical resistance and durability. In addition, their design allows them to be given a second life in certain applications, reducing waste and providing a more conscious solution.

Available sizes and colours

They are available in three formats (150×2.8 mm; 200×4.6 mm; 360×8 mm) and in two colours: black and white, thus adapting to different needs of use and finishes.

With ESTU cable ties, we simplify work without sacrificing quality.

A unique solution in the European market.

Precision turning is an essential process within precision machining, especially when we are talking about sectors that require parts with minimum tolerances, such as watchmaking, locksmithing or industrial valves. At Bianditz, as a specialised bar turning company, we understand that guaranteeing quality is not a final stage: it is an inseparable part of each manufacturing process.

Optical and three-dimensional verification

To ensure that each component complies exactly with the drawing specifications, we apply two control systems:

1. Optical verification: using high-magnification lenses that allow even subtle variations to be analysed in visual detail.
2. Verification by 3D digital probing: we use a three-dimensional verification machine, which first measures the dimensions with high-precision probes and, when the geometry requires it, activates a visual analysis camera.

Thanks to this dual system, we validate that each of our precision turning parts exceeds the highest quality standards, whether for large batches or for single parts with specific applications.

Quality assured in precision machining

In the manufacture of high-precision parts for watchmaking, locksmithing and valves, every hundredth of a millimetre matters. Our commitment to quality has led us to implement a rigorous control system that combines technical expertise with advanced means of verification.

We have verification systems that allow us to continuously and reliably monitor accuracy. This is key in micro-die-cutting processes, where parts are only a few millimetres in size and must be perfect in both form and function.
