Automotive industrial machining

Automotive machining plays a vital role in the production of high-precision mechanical parts. JACQUEMOUX DÉCOLLETAGE produces large series of machined mechanical parts for commercial vehicles, trucks, agricultural machinery, construction equipment, buses, and sports and leisure vehicles. From medium to very large production runs, our automotive machining expertise meets the reliability requirements of both manufacturers and suppliers.

Machining of parts for the automotive market

JACQUEMOUX DÉCOLLETAGE supports the automotive industry in the manufacture of specific high-precision parts, combining historical expertise in automotive industrial machining and a fleet of high-performance machines: latest generation numerical controls (CNC) and multi-spindle cam machines.

The company produces complex mechanical components, designed for light vehicles as well as for commercial vehicles and trucks, meeting the reliability requirements of manufacturers and equipment suppliers.

Automotive machining: precision technical expertise

The overall performance of a vehicle depends on the perfection of its smallest details. To meet this requirement, JACQUEMOUX DÉCOLLETAGE combines over 60 years of experience in the sector with state-of-the-art machinery. This technological investment transforms bar turning into a high-precision industrial process, capable of producing highly complex automotive components in large series.

This technical expertise is demonstrated through the machining of parts with varied characteristics, including steel, brass, stainless steel, and aluminum. Thanks to the use of CNC lathes with fixed and sliding headstocks, the workshop guarantees perfect repeatability and unwavering precision, an essential condition for high-volume automotive machining.

Ultimately, this expertise guarantees industrial production strictly aligned with the requirements of the IATF 16949 standard. The combination of historical know-how and cutting-edge technologies makes it possible to meet the most complex specifications, while respecting the highest quality standards in the industry.

Automotive parts manufacturing processes and production capacities

JACQUEMOUX DÉCOLLETAGE's industrial responsiveness is based on a structured organization, supported by its ISO and IATF certifications, capable of transforming a technical concept into perfectly controlled mass production. Each project follows an optimized manufacturing cycle:

• Technical analysis : study of the specifications and plans provided by clients in the automotive industry.
• Support and optimization: suggestions for improvement to optimize cost and time, from the project phase onwards.
• Programming: machine coding with CAD/CAM software, mainly FANUC, used in our workshop.
• Precision machining: high-volume machining of parts such as connectors, shafts, spacers or specific screws.
• Quality control: VICCI VISION dimensional control machine with vertical laser and DELTA VISION automatic control machines with tray or in-line, to guarantee 0 PPM to our automotive customers.

Beyond light vehicles: trucks and agricultural machinery

JACQUEMOUX DÉCOLLETAGE's automotive machining services are not limited to passenger cars. Our machine park and expertise in automotive machining also meet the needs of manufacturers of commercial vehicles and mobile equipment, regardless of their size or use:

• Trucks and heavy goods vehicles: Machined mechanical parts for transmission, steering or on-board connectivity systems, dimensioned for high mechanical and thermal stresses.
• Agricultural machinery: Hydraulic axles, bushings and fittings for tractors, harvesters and harvesting equipment, designed to withstand intensive outdoor environments.
• Buses and public transport vehicles: fastening and connector components meeting the same reliability requirements as those of the passenger car.
• Sports and leisure vehicles: Custom-made machined parts, in small to medium series, for specific applications.

This versatility is based on the same mastery of materials, tight tolerances and quality controls as for light vehicles, which allows JACQUEMOUX DÉCOLLETAGE to cover all the needs for turned mechanical parts for the automotive industry and associated mobile equipment.

Applications in the manufacturing of components for the automotive industry

Every component that leaves JACQUEMOUX DÉCOLLETAGE is designed to last. Automotive industrial machining is not limited to simple production; it's about understanding the interaction of each part within a complex assembly.

The machined mechanical parts for the automotive industry manufactured by JACQUEMOUX DÉCOLLETAGE are integrated into several essential sub-assemblies:

• Automotive connectors: parts ensuring reliable electrical connection in injection and on-board electronic systems.
• Axes and pivots: pivoting mechanical element in steering or suspension systems.
• Plastic supports and fixings: components ensuring the robust assembly of the various parts of the vehicle.
• Transmission elements: parts ensuring the connection between engine and gearbox, requiring tight tolerances.

These components must meet criteria for resistance to fatigue, corrosion and thermal variation, particularly in harsh automotive environments — and even more so on trucks and agricultural machinery, which are subject to particularly demanding conditions of use.

Quality, traceability and compliance in automotive machining

Ensuring consistent quality relies on an integrated management system, following the requirements of the IATF 16949 standard. Each batch of machined mechanical parts for the automotive industry benefits from complete traceability, allowing rigorous monitoring from the receipt of raw materials to final delivery.

Rigorous controls are applied at each key stage of the production flow:

• Online dimensional control: continuous monitoring through integrated metrology systems to ensure process stability.
• High-precision final inspection: 3D CMM measurements and optical systems to validate tolerances of up to one hundredth on critical dimensions.
• Compliance validation: strict control protocols guaranteeing scrupulous compliance with customer specifications and assembly constraints.

This metrological expertise is now the essential foundation for supporting the evolution of mobility. As vehicles become lighter and more electrified, components become more compact and precision requirements more stringent. This technological shift reinforces the industry's need for robust supply chains capable of flawlessly delivering high-tech components. To meet these new standards of excellence, JACQUEMOUX DÉCOLLETAGE continuously adapts its processes and invests in the technologies of tomorrow.
