The Chiyoda Seiki Cosmo Junior Z is a world-class, specialized automatic profile flame cutting machine designed explicitly for splitting, processing, and contouring shape steel, channel steel, and heavy-duty H-beams. Manufactured entirely in Japan, this high-precision machine stands out as the ultimate industry workhorse for structural steel fabricators, shipyards, and construction engineering companies.

By automating complex web and flange cuts on structural profiles, the Cosmo Junior Z replaces time-consuming manual layout marking and hand-torch inconsistencies with absolute, error-free mechanical precision.

Why the Cosmo Junior Z Changes the Game? 

• 100% Authentic Japanese Craftsmanship: Engineered with premium internal components designed to sustain flawless performance under continuous thermal stress and harsh shop conditions.

• Specialized Shape Steel Optimization: Masterfully configured to navigate the complex geometries of structural beams, making rapid, clean cuts across flanges and webs without breaking stride.

• Mechanical Tracing & Perfect Edge Replication: Employs a robust mechanical guiding assembly that effortlessly follows profile templates, keeping cutting tolerances ultra-tight.

• Eliminates Costly Post-Processing: Delivers an exceptionally smooth, dross-free thermal finish that drastically reduces manual grinding labor by up to 90%—parts are instantly ready for structural fit-up.

• Stepless Mechanical Velocity Control: Motorized travel speeds can be finely tuned to perfectly match varying structural steel thicknesses, guaranteeing square, high-integrity cuts.

• Compact, Ergonomic Portability: Features an incredibly balanced structural frame, allowing a single crane operator or team to effortlessly position, lock, and move the machine directly onto workpieces across the shop floor.
