Technologies – DENN
machinery from standard to fully custom
Positional Precision & Repeatability
DENN machinery employs electrical driven slide compounds with movement performed by slides and transmission with a servo driven pressure spindle.
Electronic Pressure Control
DENN metal spinning machines are equipped with an electric pressure control system. This system can be activated by the programmer or operator to a constant force rate, thereby avoiding adverse effects caused by temperature and other changes.
Surface Finishes & Tight Tolerances
The integration of innovative and feature-rich DENN CAD-CAM programming software, precise positioning, electronic pressure control, and high-quality components enables our customers to achieve the best possible surface finishes and tightest tolerances in the industry.
