Discover some examples of parts machined by PB Décolletage, illustrating the diversity of our expertise and the precision of our work. Each part shown reflects our ability to meet specific technical requirements, in compliance with quality standards and deadlines.


We have a machine fleet dedicated to traditional screw machining, specially configured to guarantee high productivity and consistent quality on medium and large series.
Our machine fleet includes:
These machines feature integrated in-line dimensional control systems, enabling real-time monitoring of critical dimensions. Regular inspections and systematic records are also carried out every 4 hours, ensuring consistent quality and optimal compliance of the parts produced.

At PB Décolletage, we push the boundaries of precision machining with a state-of-the-art CNC machine fleet, designed to meet the most complex industrial applications. Equipped with Index C100 CNC lathes (twin-spindle, three turrets, Ø42 mm maximum) and Nakamura WY 150 lathes (twin-spindle, two turrets, Ø65 mm maximum), we produce bar-turned parts from Ø5 to Ø65 mm, from small to large series.

This state-of-the-art equipment enables us to achieve a high level of precision, optimize production rates, and ensure consistent repeatability, all while maintaining controlled lead times. This technical mastery makes PB Décolletage a reliable partner for industries with high demands in quality, performance, and responsiveness.




We master the machining of a carefully selected range of materials, dedicated to manufacturing simple parts in large series, with a high level of precision and optimized productivity. This positioning allows us to meet the strictest industrial requirements, combining technical performance, process reliability, and material durability.
Aluminium
Lightweight and naturally corrosion-resistant, aluminum is particularly well suited to automotive and electronic applications requiring performance and low weight.
Traditional brass
A versatile, easily machinable material, brass is perfectly suited to hydraulic and electrical components. Our cam-driven machines guarantee micron-level precision and excellent repeatability in large series.
Traditional steel
Robust and cost-effective, steel is ideal for mechanical parts subject to high stress, while ensuring reliable, controlled production.
Innovation – Lead-free brass and steel
In line with environmental and regulatory standards, notably REACH, we offer lead-free alloys, reducing toxic impact while maintaining a high level of productivity. These innovative solutions are fully aligned with eco-responsible production, meeting our customers' CSR commitments.

An increasing number of manufacturers are choosing to relocate their purchasing to Europe in order to reduce their carbon footprint and secure their supply, in the face of the limitations of long, poorly traceable supply chains. At PB Décolletage, we support this transition through 100% French production, locally rooted and close to our customers.
Reducing the carbon footprint
By favoring European manufacturing, transport distances are considerably reduced compared with intercontinental flows, contributing to a significant decrease in logistics-related emissions.
Environmental commitment
PB Décolletage follows a structured environmental approach, working toward ISO 14001 certification, aimed at continuously improving the environmental performance of its operations.
Concrete benefits for your purchasing
Controlled lead times, high industrial quality, and compliance with European regulations: a responsible choice that helps improve your own carbon footprint and secures your projects.
Join the companies choosing Europe, and contact us to assess the environmental impact of your industrial project.

Many buyers turn to Asia for simple parts at an apparently low cost. Yet the real cost includes longer lead times, customs constraints, non-conformity risks, and productivity losses that directly impact industrial performance. At PB Décolletage, we favor an approach based on overall value rather than unit price alone.
Local responsiveness
Based in France, our organization enables short, controlled lead times, with fast quotes and agile production, supported by geographic proximity and complete control over our operations.
Quality and reliability
Consistent precision, rigorous inspections, and high repeatability limit rejects, rework, and production stoppages, generating lasting savings over the long term.
Optimized total cost of ownership (TCO)
Thanks to high productivity and controlled processes, we optimize costs without compromising performance, offering a TCO that is often more competitive than offshore solutions.
Sustainability and supply security
French production guarantees a reduced carbon footprint, better traceability, and a secure supply chain.
In comparison
– Distant sourcing: lead times of several weeks or more, variable quality, increased logistics risks.
– PB Décolletage: short lead times, controlled quality, and personalized support at every stage of the project.
