Abstract: Disclosed are an antigravity shear-resisting and deformation-eliminating centerless grinding apparatus and a machining method. The grinding apparatus comprises a grinding tool configured to grind a thin-walled bearing ring and a clamping mechanism configured to clamp the thin-walled bearing ring stably. The clamping mechanism comprises a main clamping mechanism and an auxiliary clamping mechanism. The main clamping mechanism comprises an electromagnetic centerless clamp. The electromagnetic coil is arranged above the thin-walled bearing ring being ground. According to the present invention, not only can gravity of the thin-walled bearing ring and a tangential force generated by grinding be counteracted to effectively prevent extrusion deformation of the thin-walled bearing ring when being ground, but also the lubricating performance the capacity to resist load itself can be further improved and the service life of is prolonged.

Abstract: A method is provided in one example embodiment and includes establishing a connection between a client and a messaging fabric of a conductor element associated with a video system and authenticating the client (e.g., involving a plurality of device credentials associated with the device). The method also includes assigning a name to identify a device associated with the client; updating a client directory with the name and a device status associated with the device; and establishing a service connection to the conductor element to enable message exchanges with the device. The service connection establishes an Extensible Messaging and Presence Protocol (XMPP)-based service.
