An auto body frame machine is used to repair damage to vehicle frames or the unitized structure of your car. Frame damage occurs in about half of all vehicle collisions, so it’s important to choose a shop with the proper equipment and trained professionals who know how to use it. Frame machines do the work that humans simply don’t have the strength to do. Frame repair is accomplished through the use of hydraulics, leverage, and sheer torque of the frame or unibody machine.
