Abstract
A rotating point for turning, which is characterized by the rotating piece that forms the conical tip, is extended by its base on a cylindrical base, from which a long rod also cylindrical, with its rear area of smaller diameter; being housed inside a tubular handle wrap with an anterior cup, which covers from the cylindrical basement to almost the entire anterior third of the shank stem, then extending this envelope to cover the rest and the rear area of the shank to join by thread to a rear plug; around the front part of the shank a slotted bushing is fitted, with calibrated rolling needles, which abut externally in a bushing fitted to the inner wall of the cup; this assembly is supported on an axial bearing, balls, in turn supported on the relief of the bottom of the cup; the rear cylindrical area and smaller diameter of the stem, has another sleeve fitted with anterior annular relief, for its antagonistic axial retention on the posterior relief of the tubular envelope; the rear area of this envelope has, in turn, fitted another tubular sleeve, and between them a crown of calibrated needles is arranged; the back threaded plug of the enclosure will stop with the inner cap of the same.
