Solid State Electronic Torque Controlled Tube Expanding Machines consist of an electrical circuit, which accurately measures the amount of current to the drive unit, provides precise regulation of the drive unit. The Machines measure the current value, thus limiting the torque at the mandrel of the tube expander. The Machines are reversible type in nature. The Solid State Electronic Torque Controlled Tube Expanding Machines are electrical and is based on the fact that under equal conditions the same amount of torque transmitted to an expander gives the same amount of expansion in tubes of identical sizes, gauge and material.
