Tighter tolerances. Less downtime.
Abrasive excellence for automotive
Since our inception, Darmann has partnered closely with transportation and automotive parts manufacturers to achieve grinding and superfinishing quality competitors cannot reach. We custom-build to achieve finer geometries across every system in modern vehicle manufacturing for both internal combustion engine vehicles and electric vehicle platforms.
Darmann helps automotive manufacturers get real results:
Ra 0.05 μm surface roughness
in fuel system and bearing applications
50% smoother surfaces than spec
in an automotive bearing application
20-second superfinishing cycles times
in automotive fuel system production
Up to 4,000 parts per grinding wheel
in automotive fuel system production
Automotive manufacturing applications
In the automotive world, millimeters and microns matter just as much as dollars and cents. Darmann boasts four decades of experience supporting automotive parts engineering and production.
