Bonnell Spring Machines

GENMAX offers five main models: F130, F120, YHJ-100, YHJ-80 and YHJ-60...

Check frame strength and motor power. Examine coil forming precision and knotting quality. Look for user-friendly control systems and automated lubrication.
Match the machine to your productivity requirements. Consider your budget constraints when selecting models. Ensure proper safety guards protect operators.

F-120 features manual spring height and turns adjustment, mechanical cam spring winding, and Chinese Inovance Electric PLC. F-130 offers digital control of spring height, turns, and end diameter, with advanced three-axis linkage CNC spring adjustment, and premium imported components (Beckhoff PLC and Schneider touch screen).

Check components monthly for wear. Clean the machine after each production shift.
Always turn off main switch before cleaning. Use gasoline-soaked brush for steel wire parts, dry cloth for painted surfaces. Keep string spring device especially clean.
NEVER use water or compressed air. Clean oil spills immediately. Regular maintenance ensures optimal performance and safety.
