With the ML Planetary System the tube is not spinning. The abrasive belts rotate around the tube while it is safely transported by the feeding systems. The ML100 was designed to finish either straight tubes (automatically) or bent tubes (manually). The ML100 tube polishing machine is simple to work with. The automatic feeding system is hinge mounted and easily removable for bent tube finishing. The light contact with the abrasive belts on the ML Planetary System generates very little heat on the surface of the tube, unlike other more conventional systems. Oval or elliptical tubes polishing or simply out-of-round tubes can be safely and consistently finished with the ML100. Maximum adaptability of the abrasive belt to holes or graps in the material surface. The ML100 has a removable cover at the exit of the grinding head that leaves a bigger, more flexible opening to allow you to finish more challenging bends and tighter radii with less effort and better, more uniform results.
