RADIAL SUPPORT DEVICE FOR THE STAY TYPE FOR A ROTARY WORKPIECE TO BE MACHINED, GRINDER EQUIPPED WITH THIS DEVICE AND, IF REQUIRED, WITH AN AUTOMATIC LOADING/UNLOADING MECHANISM AND ITS USE PARTICULARLY FOR THE MACHINING OF MILL ROLLS

摘要

ABSTRACT OF THE DISCLOSURE:Radial support device of the stay type, forexample for a cylindrical surface grinder, in which the staycomprises two arms equipped with fences associated withjacks and is designed in such a way that the fences remainlaid against the workpiece during machining, for the entireduration of this, at a pressure which is virtually constantdespite the change in size of the workpiece as a result ofthe removal of material. The grinder is also equipped withan automatic mechanism for picking up the workpieces to bemachined from a stocking table by means of manipulatorscarried by a carriage movable on a beam, depositing them onthe machine tool and, once machining has been carried out,retrieving them in order to replace them on the stockingtable. The invention is used for the grinding of millrolls.
