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

Radial support device of the stay type, for example for a cylindrical surface grinder, in which the stay comprises two arms equipped with fences associated with jacks and is designed in such a way that the fences remain laid against the workpiece during machining, for the entire duration of this, at a pressure which is virtually constant despite the change in size of the workpiece as a result of the removal of material. The grinder is also equipped with an automatic mechanism for picking up the workpieces to be machined from a stocking table by means of manipulators carried by a carriage movable on a beam, depositing them on the machine tool and, once machining has been carried out, retrieving them in order to replace them on the stocking table. The invention is used for the grinding of mill rolls.
