Condition: new, Hemming tool for Amada/promecam Iedpfx Ahoqxq Hboyjih

Year of construction: 2026, condition: new, functionality: fully functional, machine/vehicle number: KP, Compatible with Amada, promecam, Durma, Ermaksan, Baykal, YAWEI, Ital, Dener, This high-precision gooseneck punch is fully manufactured according to Amada European standard specifications, perfectly compatible with Amada press brakes and most mainstream European-style bending machines. Designed specifically for complex sheet metal bending, this gooseneck upper tool effectively solves the interference problem that ordinary straight punches cannot avoid during deep bending, reverse flanging, U-shaped grooving and multi-angle forming. Featuring an optimized curved gooseneck structure, the punch provides sufficient avoidance space during bending. It prevents collision with vertical edges and folded surfaces, allowing one-step integral forming of deep cavity workpieces, box structures and special-shaped sheet metal parts. It greatly reduces secondary cutting, welding and reshaping procedures, improving workpiece integrity and production consistency. Made of high-quality alloy tool steel with integral vacuum quenching and tempering treatment, this Amada-style punch delivers high hardness, outstanding wear resistance and strong compression resistance. CNC precision grinding ensures stable bending angles, smooth forming surfaces and long service life without deformation under continuous high-load operation. Standard size tolerance and unified positioning structure enable seamless installation with Amada punch holders and clamping systems, ensuring high repeat accuracy during batch production. Ideal for electrical cabinets, equipment housings, automotive sheet metal and custom metal bending parts, this gooseneck upper punch significantly upgrades your bending efficiency and finished quality. Key Features Iisdpfjqxq Nwsx Ahyoh ✅ Fully compatible with Amada standard press brake tooling systems ✅ Anti-interference gooseneck design for complex one-shot bending ✅ High-strength heat-treated alloy steel for long service life ✅ CNC precision grinding for stable bending accuracy ✅ Greatly reduces secondary processing and production costs ✅ Widely used for cabinet, automotive and mechanical sheet metal fabrication
