Selected projects

From design to series —
four examples.

Four projects from metrology, aerospace, testing and manufacturing — each from design to use in series production, from a single source.

Part holders for the GOM measuring cell.

Starting point

Integration of a precise part holder for rail systems into an existing measuring cell — directly into running series production.

Implementation

Concept, design, manufacturing and integration of the holders into the existing measuring cell — matched to the cycle time of the running series.

Result

The holders run at series cycle time — without modifying the measuring cell.

Part holding down to ± 0.1 mm

Reference project · Aerospace · Assembly & Inspection

Multi-jig: several variants in one fixture.

Starting point

Several part variants are to be held, assembled and inspected in a single fixture — instead of a separate fixture for each variant.

Implementation

Design, manufacturing, measurement, fitting of the measuring probes, control cabinet and interface to the ERP system — all from a single source, with official inspection report.

Result

In use in series production. Measured values go straight into the ERP without manual transfer.

Inspection gauge with sensors.

Starting point

A component has to be checked for dimensional accuracy quickly on the shop floor, without a metrology room — repeatably, independent of the operator and directly at the workstation.

Implementation

Inspection gauge on a machined aluminium base plate: zero-point stops, clamping elements with ball handles, pneumatic slides and sensors for presence and position checks — designed, machined and assembled in-house.

Result

Pass/fail decision in seconds instead of a metrology room. Every check under the same conditions — regardless of the operator.

Reference project · Mechanical engineering · Manufacturing & Assembly

Assembly production: milled, assembled, inspected.

Starting point

Aluminium assemblies in series — several milled parts per unit, to be assembled with precise fit and delivered ready to install.

Implementation

3- and 5-axis milling of the individual parts, assembly and inspection in-house — one responsibility from drawing to finished assembly.

Result

Ready-to-install assemblies in series — no interfaces between machining and assembly.
