SM Servo Hemming System
1 Development Background
Hemming method for automobile body production process has mainly used the hydraulic power for power source but recently is gradually
proceeding to eliminate the hydraulic power according to the latest environmentally-friendly policies.
To respond the trend the major automobile companies including subcontractors have a tendency to focus on developing roller hemming making use of robot and electric hemming making use of motor.
However, roller hemming using robot are indicated to have several weak points such as unsuitability to apply for mass production line due to excessive process time, possibility to occur quality dispersion depending on robot operation skills, and necessity to conduct the regular inspection of calibration to maintain a constant quality.
To supplement all of these problems we have developed hemming system utilizing servo motor for one of the options.
