Additional services
Quality
Quality assurance follows the four-eyes principle of operator self-inspection; on customer request, a documented 100% inspection with verification records is performed. A coordinate measuring machine ZEISS CONTURA with Calypso software is used for metrology; delivery reliability was above 98% from 2023 to 2025.
