The SJ SERIES Bench Power Press Machine (Model SJ04-4T) is a compact, high-precision desktop mechanical punching machine engineered for light-duty industrial manufacturing. Featuring a robust 4-ton pressure capacity, this bench model is optimized for workspace efficiency and rapid cycle times.
Key Specifications & Mechanics
- Capacity: 4 Tons of nominal force.
- Speed & Performance: Operates at high speeds up to 200 strokes per minute (SPM) for maximized output.
- Driving Mechanism: An electric motor drives a heavy flywheel, storing rotational energy transferred via a clutch system to the ram.
- Controls: Supports dual activation methods via hand button panels or foot pedals to prioritize operator safety.
Primary Industrial Applications
The machine processes sheet metal, plastics, and electronic components across several manufacturing operations:
- Blanking & Cutting: Providing clean, burr-free edges on small components.
- Punching & Slotting: Delivering high-precision hole placement.
- Bending & Forming: Executing consistent, repetitive geometries.
- Riveting & Assembling: Performing small hardware joining tasks.
Structural Benefits
Built from a heavy cross-section steel frame, the machine provides extreme rigidity to minimize angular deflection under load. Its small footprint allows it to sit easily on standard workshop tables, making it highly portable and simple to repair compared to heavy-duty floor-mounted presses.
