Provided is a technique allowing an effective process of a bevel portion of a workpiece. A processing apparatus 1 includes a workpiece table 10 configured to hold a workpiece Wf, and a processing head 30 configured to hold a processing pad Pd. The processing pad includes a pad surface 120 provided with at least one groove 130 having an inner circumferential groove wall 131 and an outer circumferential groove wall 132. The processing apparatus 1 is configured to rotate the workpiece table and the processing head, and bring an edge 133 of the inner circumferential groove wall and an edge 134 of the outer circumferential groove wall in contact with a bevel portion 100 of the workpiece during a process of the workpiece.

An apparatus for spot polishing the work rolls of a metal sheet or plate leveler having a series of upper work rolls and a series of lower work rolls. The apparatus includes an assembly comprising a spot polisher frame, an airbag or other position translation element, and a polisher, including an abrasive surface, configured to radially polish only a portion of an upper or lower work roll. The apparatus further includes a polisher arm, to which the abrasive polisher is attached, at a first end of the polisher arm. The apparatus further includes a second end of the polisher arm hingedly connected to the spot polisher frame so as to enable the repositioning of the abrasive surface between a polishing and non-polishing orientation.

The invention concerns a method for machining a workpiece (1) by a grinding machine, comprising the step of rotating and translating the workpiece along a first axis (4) toward the first abrasive wheel; rotating an abrasive wheel (6) around a second axis (61) and translating it along a third axis (62) such that the abrasive wheel grinds a peripheral portion (103) of the workpiece; the abrasive wheel being positioned in a position in translation along the third axis; and wherein the position in translation is determined as a function of a position and of an angular position of the workpiece around the first axis. The invention further related to a grinding machine for carrying out such method.
