CNC Hydraulic Shearing Machine – Top Choice for Sheet Metal Blanking: Practical Advantages

Blanking is the first procedure in sheet metal processing, where CNC hydraulic shearing machines are indispensable. Taking the Q12Y/K swing beam and QC11Y/K guillotine models from Shanghai No.1 Forging as examples, the complete machine adopts all-steel welding with stress relief via vibration aging, resisting deformation after long-term cutting. Equipped with standard ball screw backgauge paired with the A60 CNC system, it supports programming of 99 multi-step programs and automatic storage of dimensional parameters, controlling dimensional tolerance within ±0.1mm for mass sheet cutting. The guillotine model features a three-point support guide wheel design that delivers ultra-smooth cutting edges with minimal burrs, compatible with stainless steel, carbon steel, aluminum sheets and other materials. The swing beam model offers higher cost performance and suits mass blanking of thin plates. An optional pneumatic sheet support device automatically holds sheets before and after cutting to reduce manual handling wear. Routine maintenance only involves regular guide rail cleaning and hydraulic oil replacement, making it stable for blanking production in cabinet, kitchenware and construction sheet metal factories. It is an essential foundational machine for sheet metal production lines.
