Large-Format Precision | 650 Ton / 6500 kN
Large-Format Precision Fine Blanking Press
When your part diameter demands more platen space. The HF-650 handles thick plates up to 16 mm and large-diameter components where die size exceeds the table capacity of smaller machines, from truck transmission gears to excavator pinion blanks.
Typical applications: Large-diameter gears (180mm+), truck transmission components, wheel-hub flanges, tractor gears, excavator pinion blanks, truck-axle reinforcement plates
Consider a manufacturer producing 200mm-diameter sprockets for truck transmissions. The die for this part requires a platen diameter that exceeds the 400 mm back-pressure platen on the HF-500. Beyond die fit, the asymmetric geometry of large-diameter gears creates significant side-loading during the blanking stroke. On a smaller machine, this side-load causes die shift, producing dimensional drift and inconsistent edge quality around the part circumference. The HF-650 solves both problems. Its 450 mm ring gear platen and 450 mm back-pressure platen accommodate the larger die footprint, while the 45-tonne whole-welded frame, FEA-verified for rigidity under asymmetric loading, resists die shift and maintains parallelism between platens throughout the stroke. The 3250 kN V-ring force ensures full material clamping across the larger die area, while 1625 kN counter-pressure maintains compressive stress on the shear zone for crack-free edges on thick-plate components.
Running at 55 strokes per minute with a 450 mm maximum feed width and ±0.1 mm pitch accuracy, the HF-650 balances heavy-tonnage capability with production throughput suitable for automotive Tier-1 and heavy-equipment OEM supply chains. The 850 x 850 mm working table and 750 mm die height support large progressive dies for multi-feature parts produced in a single stroke. Typical applications include wheel-hub flanges, tractor transmission gears, excavator pinion blanks, and truck-axle reinforcement plates where burr-free edges and dimensional stability eliminate downstream machining on high-value structural components. For manufacturers whose part geometry simply does not fit on smaller platens, the HF-650 is the entry point into large-format fine blanking.
