3 High Precision Transmission Gear Machined gears provide smooth and silent operation. High Quality Crank Shaft The ground and polished crankshaft is designed for extra rigidity to ensure accurate part quality and consistency. High Torque Wet Clutch/Brake Unit Multi-plate, low inertia design for quick response. Designed for high repetition for single stroke or automatic single stroke applications. Enclosed unit eliminates air pollution and provides smooth, quiet operation. 2

4 FEATURES Full Length 6-Point Bronze Gibs Adjustable, durable bronze alloy linings are fixed directly to the frame. Slide length gibs maintain slide guidance accuracy and extend tool life. Eliminates Side Thrust Forces Counter-rotating gear design minimizes side thrust forces. FRAME SLIDE Automatic Lubrication System Features monitored distribution block and fault indication. Motorized Slide Adjustment Push button operated with keyed selector switch for fast and reliable die height adjustment. Digital Die Height Indicator Motorized slide adjustment with pre-set limits has die height indicator with 0.1mm increments. Ross TM Dual Safety Valve Safe, reliable operation with crosschecking and fault indication. 3

5 Quick Die Change System (Optional) Die lifters, clamps and auxiliary rails allow for fast and easy die changes. A variety of setups are available. Operator Controls Honeywell Wintriss WPC 1000 control features a user-friendly design for simple, safe, reliable operation. Tonnage Curve Hydraulic Overload Protection Factory pre-set at 110% of rated press capacity, the hydraulic overload protection system prevents damage to press components due to incorrect die height setting. Freeing stuck dies at the bottom of the stroke can be easily accomplished.
