Overview Points

Shears mild steel plate up to 20mm thick and 2600mm wide at a rated shear strength of 450 N/mm², handling demanding fabrication workloads without compromise.

All-steel welded frame with gate-type (guillotine) architecture provides high rigidity and vibration resistance, maintaining cut accuracy over years of continuous service.

MD11 numerical control system with digital display manages back gauge positioning (10–700mm range), reducing setup time and operator error on repeat jobs.

Adjustable shear angle (3°) and hand-wheel blade clearance mechanism let operators fine-tune cut quality for different material grades and thicknesses.

Nitrogen cylinder return ensures fast, smooth ram retraction — achieving 12 cuts/min under load and 14 cuts/min at no-load — maximizing throughput on production runs.

Integrated hydraulic hold-down clamps press the sheet before each cut, preventing material shift and delivering clean, distortion-free edges.

Motorized back gauge with 0.37 kW drive and lead-screw positioning enables rapid, repeatable dimension changes directly from the control panel.

800mm worktable height, 3200 × 2000 × 2000 mm footprint, and 22 kW main motor make this machine practical for medium-to-large fabrication shops without excessive floor-space demand.

Key Features

Rigid All-Steel Welded Construction

The frame and tool holder are fabricated from heavy-gauge welded steel plate, delivering the stiffness required to shear 20mm plate at 450 N/mm² without deflection. Roller-supported upper tool rest travel further reduces structural stress, preserving geometric accuracy across the machine’s service life.

MD11 Numerical Control with Digital Display

The Hong Kong Sanyuan MD11 CNC module provides direct numeric input for back gauge position (10–700mm), stroke count, and shear parameters. Operators set dimensions once; the system drives a 0.37 kW motor and lead-screw assembly to position the gauge accurately, eliminating manual measurement on batch work.

Fast Cycle Time with Nitrogen Return

Nitrogen-charged cylinders retract the ram immediately after each cut, enabling 12 strokes per minute under load. This mechanical return method is simpler and more responsive than spring-based alternatives, reducing maintenance while keeping cycle times short.

Precision Blade Clearance Adjustment

A three-point eccentric support shaft at the rear of the tool holder, combined with a front-mounted hand wheel, allows fine adjustment of upper-to-lower blade clearance. Correct clearance setting minimizes burr formation, extends blade life, and produces clean sheared edges across the full 2600mm blade length.

Integrated Safety and Clamping

Hydraulic hold-down cylinders press the workpiece firmly before the blade engages, preventing sheet movement and ensuring dimensional consistency. An emergency stop on the foot-switch remote and pressure-spring-assisted clamp reset add further operator protection during high-speed production.

Technical Specifications
