Steady rest for rolling mill roller-grinding machines incorporating automatic charging and discharging means.

摘要

Radial-support device of the steady-rest type for, for example, an external cylindrical grinding machine (100) where the steady rest (140) comprises two arms equipped with jaws associated with actuators and is arranged so that the jaws remain applied against the workpiece (10) throughout the machining, and with a virtually constant pressure in spite of the change in dimension of the workpiece resulting from the removal of material. The grinding machine is also equipped with a robot (200) for taking the workpieces from a storage table (210) with the aid of manipulators (223) carried by a carriage (221) which can move on a beam (222), depositing them on the machine-tool and taking them up again, once the machining is complete, and replacing them on the storage table. Application to the grinding of rolling-mill rollers. <IMAGE>
