HB HUMMINGBIRD 60 & 80 TONS CAPACITY BULLETIN
●Speed and Precision.
◆Minster Hummingbird presses provide consistent accuracy automated high speed blanking. The 80 metric ton machine is capable of 1000 SPM with a stroke length of 25mm making the Hummingbird the fastest machine of its type in this tonnage range.
●One-Piece Cast Frame.
◆The Hummingbird frame is of class 40 grade cast iron. Minster's construction provides the compressive strength and vibration dampening that provides greater die life and part accuracy.
●Heavy Duty Bed for Stability and Precision.
◆The massive bed of the Hummingbird press has a maximum deflection of .001" per foot increasing die life and improving part quality.
●Heavy Drive Connection and Rigid Slide.
◆The Hummingbird slide is designed to minimize deflection under full loading. The high strength 1045 steel connections and pistons are made specifically for high speed blanking. This feature, designed to handle snapthrough forces equal to 50% tonnage rating of the press, reduces punch penetration and promotes die life.
●Flywheel Drive Arrangement for Maximum Press Efficiency.
◆The Hummingbird series are flywheel type presses to provide higher speeds for punching, notching and blanking operations. Minster's patented combination hydraulic clutch and brake produces the maximum torque possible providing for faster starting and stopping, resulting in increased production. A segmented drive disc design provides easy maintenance. In addition, Minster's clutch and brake unit requires no adjustment and years of maintenance-free operation, resulting in less downtime and higher production rates.
●Dynamic Balancer System.
◆The dynamic balancing system on the Hummingbird greatly reduces the effect of the slide and tooling inertia forces caused by running at high speeds. This recipro- cating balancer helps maintain precise slide bottom- dead-center repeatability resulting in less die wear and greater part accuracy.
