Etablissements Gonon

What they make

According to their website, Etablissements Gonon is a family-owned precision turning (decolletage) workshop in Le Chambon-Feugerolles, France, producing custom parts as single units or small batches with no minimum quantity. They machine bronze, steel, aluminium, stainless steel and plastic, working from round, hexagonal, tube and other bar profiles, in diameters from 8 to 60 mm (down to 2 mm on request). Equipment spans a traditional Cazeneuve lathe for single-piece turning up to 50 mm diameter, plus two Nakamura-Tome CNC lathes with two-axis (X/Z) control: an SC-250 for series parts from 5 to 42 mm and a TMC-15 for series parts from 32 to 60 mm, combining century-old machinery with more modern numerically controlled equipment. Each request is handled by a technician working from paper or 3D drawings, who defines the manufacturing routing before a quality-control step. The site describes the firm as a small family structure passed down across generations, preserving both its know-how and its older machine tools. No certifications, standards, or export markets are stated.
