Rubis Precis Group

What Rubis Precis Group does

Rubis Precis Group is a privately-held French industrial group founded in 1948 that manufactures high-precision components from hard materials—technical ceramics, ruby, sapphire, and tungsten carbide—and from metals and alloys including precious metals. Operations span three wholly-owned entities: Rubis-Précis (Charquemont) for bar turning and metal machining, Micropierre (Besançon) for diamond-wheel grinding, lapping, and optical-quality polishing of hard materials, and High Tech Ceram (Darvault, acquired in 2011 from German firm DPL Friatec) for technical ceramics and ceramic-metal brazed assemblies. The group combines these capabilities into integrated sub-assemblies using laser welding, induction brazing, press-fitting, and crimping, achieving tolerances of ±2 µm on internal diameters and ±3 µm on external diameters on ruby and sapphire pieces.

The customer base is enterprise-focused and diversified across metrology, aerospace, defense, medical/biomedical, watchmaking and luxury goods, optical/fiber-optical, semiconductor, and scientific-instrument end markets, with 50% of revenue exported to 15 countries. Manufacturing capacity totals 8,400 m² across three French sites, producing approximately one million parts per month at unit prices ranging from €0.10 to over €10,000 depending on complexity. The group holds ISO 9001 and ISO 9100 certifications and is approved at French Defence Secrecy Level, enabling participation in military, missile, and aerospace programs.

Commercially, the group operates a sales-led direct model: a team of three sales technicians supported by international sales agents across Europe and the United States, with customer acquisition driven primarily by trade-fair participation and professional referrals. Revenue mechanics are quote-based custom manufacturing under multi-year framework agreements with industrial OEMs, with no disclosed external investors, public listing, or recent funding events. The group is controlled by the Chaney family, with Philippe Chaney serving as site responsible and Clara Chaney as site administrator.

Core offering

Rubis Precis Group manufactures high-precision components and sub-assemblies from hard materials (ruby, sapphire, technical ceramics, tungsten carbide) and metals/alloys for industrial buyers. The group operates three divisions—Rubis Precis, Micropierre, and High Tech Ceram—providing precision machining, micro-assembly, and hard-material finishing services to the metrology, aerospace, medical, defense, luxury, and semiconductor sectors.

Product overview

Rubis Precis Group is a precision micro-manufacturing consortium comprising three divisions: Rubis Precis (bar turning and metal machining in Charquemont), Micropierre (hard material grinding and polishing in Besançon), and High Tech Ceram (technical ceramics machining in Darvault). The group produces high-precision components from hard materials (ruby, sapphire, tungsten carbide, technical ceramics) and metals (stainless steel, brass, titanium, precious metals), offering micro-assembly services that combine these materials. The three divisions operate cooperatively to serve industries including metrology, medical/biomedical, aeronautics, defense, luxury goods, optical/fiber-optical, semiconductor, and scientific instruments.
