Entry-Level Precision | 200 Ton / 2000 kN
Entry-Level Precision Fine Blanking Press
When your part demands fine blanking, not just stamping. The HF-200 delivers burr-free, 100% shear-zone edges on small precision components up to 8mm thick, replacing multi-step machining with a single-stroke production method.
Typical applications: Lock cylinders, connector terminals, small gears, seat-belt retractor components, medical device blanks, electronic housings
Consider a lock cylinder manufacturer running conventional stamping: the blank comes off the press with torn edges, requiring secondary drilling and milling to meet pin-tolerance bore specs. Three operations, three setups, three quality risks. The HF-200 changes that equation. Its 1000 kN V-ring impingement force clamps the strip material against the die before the cutting punch descends, holding the material in compression throughout the shear zone. The result is a die-roll height below 10% of material thickness and edges that meet IT7-8 dimensional tolerances straight off the press. For a typical 3mm C45 lock-cylinder blank, the HF-200 consolidates blank, drill and mill into a single stroke, cutting cycle time by up to 60% and eliminating the tear fracture that conventional stamping produces on small-diameter features.
The 200-ton platform processes low- to medium-carbon steels (C45, C60), stainless steels (304, 420), aluminum alloys and brass with consistent edge quality across temper grades. At 80 strokes per minute with servo-driven coil feeding at ±0.1 mm pitch accuracy, the HF-200 sustains high-volume production of small precision parts where dimensional repeatability across batches is non-negotiable. Common deployments include dedicated cells for electronic connector housings, small powder-metal-replacement blanks, and seat-belt retractor pawls where burr-free edges eliminate downstream deburring on safety-critical components. The compact 500 x 500 mm working table and 14-tonne footprint make it well suited for job shops and Tier-2 suppliers who need fine-blanked part quality without the capital outlay of larger presses.
