in North America, Europe and China. Precision kinematics reportedly enables quicker system response and higher pro- duction rates than previous series versions, and eccentric wheels with double-helical gearing allow for smooth operation, increased power transmission and higher durability. The Desch planetary gearbox, standard on this series, reduces drive-
train inertia for quicker acceleration and faster stopping times, according to com- pany officials, who also note that the Siemens full energy-management system provides maximum energy efficiency and low power cost per part. Another series feature: Zero-clearance slide guiding improves die setup and operation.

officials, while noting that this requires precise positioning and leveling of a press slide and table. Considering this challenge, Schuler has in place a penetration-depth control (PDC) to provide the needed posi- tioning as well as repeat accuracy of the slide, achieving an interlock exactly at the penetration depth. The Schuler Smartline series can adjust the PDC at 0.01-mm increments through the entire stroke range.
The longer slide length requires con- sideration of deflection. Here, Schuler placed a strain gauge in the kiss blocks of the die, enabling press force to be kept constant while controlling slide deflection.
The EV 3.8 can reach 250 strokes/min. with full press force of 3150 kN and a maximum upper-die weight of 6 tons, with no need for special foundation. Also, no wear parts in the slide guiding, pressure points, connection rods and main bearings means minimized service costs. With the above-listed features as well as use of two pressure points, four pretensioned slide guidings, and optimal interaction of the static and dynamic counter balance, die lifetime can be increased by as much as 30 percent, according to Schuler officials.
