Abstract
Mechanical device for grinding valve seats characterized by comprising a cylindrical and hollow body supported axially on the end rod of a guide body with intercalation of radial bearings that allow a slight relative axial displacement whose cylindrical body externally and removably carries a milling wheel and elastically receives a rotation movement through a flexible shaft connectable to a machine of the type of manual drills.
