Zeh Präzisionsteile

What Zeh Präzisionsteile does

Zeh Präzisionsteile GmbH is a family-owned German contract manufacturer of precision turned and milled parts, founded in 1996 by Dieter Zeh and headquartered in Illertissen, Swabia. The company produces CNC turned parts (Drehteile) using multi-spindle lathes, long-turning machines, and fine-finishing operations, alongside CNC milled parts (Frästeile) on horizontal machining centers equipped with pallet systems, and assembles complete subassemblies (Baugruppen) including proprietary-design pneumatic cylinders for printing machines, compressor relief pistons, and assembled camshafts. Materials processed include stainless steel, non-ferrous metals, castings, and sintered materials, with batch sizes ranging from 100-unit small series to one-million-piece production runs across a three-shift operation.

The technical stack centers on conventional, well-proven precision machining rather than digital or AI-native technology. Quality assurance relies on 3D coordinate measuring machines and bidirectional integrated measurement systems embedded in production lines, and full in-house manufacturing depth covers milling, turning, grinding, broaching, coating, and hardening. The company holds DIN EN ISO 9001:2015 certification (TÜV SÜD, valid 22.05.2024–21.05.2027), continuously maintained since initial ISO 9001:2000 certification in 2003.

The business model is a straightforward B2B contract-manufacturing model: revenue is generated per-part on a quote-based pricing structure determined by complexity, material, batch size, and finishing operations, with no public pricing disclosed. Customers are reached exclusively through direct sales (phone, email, contact form) and consist of industrial OEMs and Tier-1s in automotive and drivetrain, hydraulics, bearings, machinery, compressor/pump, and medical technology. The company serves customers worldwide from a single 12,000 m² site in Illertissen, with approximately 2,400 m² of production space plus a 2,000 m² expansion added in 2018. Ownership is fully retained by the Zeh family (Jennifer Zeh as Managing Director, Dieter Zeh in an advisory role), with no external investors, parent company, subsidiaries, or public listing.

Core offering

Zeh Präzisionsteile GmbH manufactures custom CNC turned parts, CNC milled parts, and complete precision assemblies for industrial customers. The company operates multi-spindle lathes, long-turning machines, and horizontal machining centers in a three-shift model, processing stainless steel, non-ferrous metals, castings, and sintered materials with lot sizes from 100-piece small series to 1 million pieces. It also delivers fully assembled subassemblies such as pneumatic cylinders, compressor crankcases, and relief pistons, supported by in-house heat treatment, surface coating, and integrated quality assurance.

Product overview

Zeh Präzisionsteile GmbH is a manufacturer of precision CNC-turned and CNC-milled parts operating from Illertissen, Germany. The company's core offerings center on three integrated manufacturing capabilities: CNC turning (Drehteile) using multi-spindle lathes and long-turning machines; CNC milling (Frästeile) on horizontal machining centers; and complete assembly of precision components into finished Baugruppen (assemblies). The portfolio includes specific product families such as Pneumatikzylinder (pneumatic cylinders) with proprietary designs for printing machines, gear components including Getriebesteckwelle (gear stub shafts), Getriebeteile (transmission parts), and Schalträder (shift gears); hydraulic components such as Hydraulikanschlüsse (hydraulic connections) and Überwurfmuttern (overarm nuts); and specialized parts like Entlastungskolben für Kompressoren (relief pistons for compressors), Dichtungsbauteile (sealing components) in difficult-to-machine stainless steel, and Innenring Wälzrollenlager (roller bearing inner rings). The company operates a full production cycle including raw material cutting, CNC machining, heat treatment, surface coating, and final assembly—delivering lot sizes from 100-unit small series to production runs of 1 million parts across three-shift operations.
