Abstract:
A grinding machine comprising a main frame, a wheelhead and a worktable, defining a workpiece axis, wherein the wheelhead is slidable relative to the mainframe perpendicularly to the workpiece axis, and the worktable is slidable relative to the main frame perpendicularly to the direction of movement of the wheelhead, and a computer supplied with data indicative of at least one operational parameter of the grinding process, wherein the wheelhead feed is under the control of signals generated by the computer, and further comprising:(a) a frame hingably mounted on the wheelhead parallel to the workpiece axis, (b) two independently driven small diameter grinding wheels are mounted on the frame remote from the hinged mounting, (c) pivoting of the frame causes the axis of one or the other of the two small wheels to be aligned with the workpiece axis, (d) the worktable includes a headstock including a workpiece drive for rotating a workpiece during grinding, and (e) the pivoting of the frame and the speed of rotation of the workpiece driver are also controlled by signals generated by the computer.
