Positional Precision & Repeatability
DENN machinery employ electrical driven slide compounds with movement performed by slides and transmission with a servodriven pressure spindle.
Electronic Pressure Control
DENN metal spinning machines come equipped with an integrated electric pressure control. This system can be activated by the programmer/ operator for maintaining constant force rate, for example to avoid adverse effects due to temperature changes.
Surface Finishes & Tight Tolerances
The combination of the innovative and feature-rich DENN CAD-CAM programming software, precise positioning, electronic pressure control and the use of quality components allow our customers to achieve the best possible surface finishes and tight tolerances in the industry.
