Abrasive machining apparatuses and methods of finishing glass articles with abrasive machining apparatuses are disclosed herein. In one embodiment, an abrasive machining apparatus includes a support base, an edge finishing unit, and an edge finishing unit position sensor. The edge finishing unit includes an abrasive machining spindle having an abrasive wheel that is coupled to a motor and a pivot mechanism that is coupled to the support base. The pivot mechanism has an axis about which the abrasive machining spindle pivots. The abrasive machining spindle is pivotable between an extended position and a retracted position. The actuator is coupled to the edge finishing unit and to the support base and selectively positions the abrasive machining spindle about the axis. The edge finishing unit position sensor is coupled to the support base and is oriented to detect a position of the abrasive machining spindle.

Abrasive machining apparatus for processing edges of glass articles

This disclosure features use of a paper or polymer film that includes a slip agent that can transfer to its surfaces. Once the paper or film is pressed against a glass sheet, this will leave a thin surface roughness of slip agent that can prevent or reduce glass surface scratches from other surfaces or particles during shipping or finishing (e.g., cutting to size, conveyance of glass), thereby improving the yield of glass shipments between glass forming plants and customers. The thin discontinuous layer of slip agent remaining on the glass surface can be washed off easily in subsequent washing processes. The paper or film can have the slip agent imbibed within the paper or coated on it as a surface member.
