DENN – High Standards for the Metal Spinning & Flow Forming Machinery Industry

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.
