About UTA GmbH
UTA GmbH is an owner-managed contract manufacturer based in Aschaffenburg, specialised in demanding individual parts, small series and custom-made products. The service portfolio includes CNC milling with 5-axis simultaneous milling machines and 3D milling machines (travelling range up to 2000 × 1000 × 1000 mm), CNC turning of parts from Ø 2 to 1000 mm with tolerances in the micron range, and CNC grinding of hardened steels with Ra values below 0.4 µm. A second pillar is gauge making, including go/no-go snap gauges, hub and shaft keyway gauges, go/no-go groove gauges and custom designs made to customer drawings. Materials include steel, stainless steel, aluminium, brass and tool steels such as 1.2379, 1.2842 and 100Cr6. Customers include mechanical engineering, plant engineering, nuclear technology, metrology, medical technology, automotive and aerospace suppliers as well as the electrical industry. At the Aschaffenburg-Schweinheim site, 17 employees manufacture on around 20 machines; quality is certified to DIN EN ISO 9001:2015.
