Atelier LOUIS PROUVIER - PRECIFAB
PRECIFAB, established in Villeurbanne since 1974, is a precision machining workshop specializing in turning and centerless grinding. We expertly handle a wide range of materials—including special steels, stainless steel, titanium, and technical plastics—and primarily focus on small-batch production and prototyping, delivering optimal responsiveness to meet the demands of industrial clients.
Our expertise extends to parts up to 300 mm in length and 60 mm in diameter, with strict tolerances. Thanks to our agile organization, we ensure rapid processing of requests, direct technical dialogue, and an unwavering commitment to quality.
As an indirect partner to the defense, aerospace, energy, and medical sectors, PRECIFAB is currently experiencing a phase of renewal and growth. We leverage our core values—proximity, reliability, and performance—to offer a flexible and high-performing alternative to traditional subcontracting chains.
