THE METHOD OF PROCESSING THE INSIDE OF INNER TUBE FOR STEERING WHEEL
摘要
<p>The present invention relates to a manufacturing method of an inner tube for a steering column of a vehicle. The present invention reduces manufacturing costs and improves production efficiency by not requiring a cutting process since the inner surface of an inner tube is processed by locating the inner tube between a work plate and a lower plate of a compression jig and applying external force from the top. In addition, the present invention prevents damage to materials caused by high-temperature heat generated during a welding process.</p>
