A centerless grinding machine having a control wheel and a grinding wheel for machining cylindrical workpieces is adjusted prior to a machining operation using a setting component having the same diameter as the workpiece. The setting component is used so as to ensure that a surface of the control wheel is aligned with a guide surface of an outlet guide so as to facilitate accurate machining. Relative movement of the control wheel and the outlet guide enables an electrically conducting portion of the setting component to complete an electrical circuit when the two surfaces are in alignment. A current meter is activated when alignment is achieved. The setting component enables the machine to be adjusted at a remote location. The machine may therefore be located within a shielded enclosure for machining nuclear fuel pellets.
Apparatus for performing a machining operation on a workpiece, the apparatus comprising a control member having a first surface for locating a workpiece during a machining operation, an outlet glide having a second surface for guiding a workpiece away from the control member, the control member and the outlet guide being movable relative to one another to enable alignment of the first and second surfaces, an electrical circuit including an indicating means, and a setting component comprising an electrically conducting portion for use in aligning the first and second surfaces prior to machining a workpiece, wherein relative movement of the control member and the outlet guide enables the electrically conducting portion of the component to complete the electrical circuit and thereby activate the indicating means when the first and second surfaces are in alignment.
A method of setting up an apparatus for performing a machining operation on a workpiece, the apparatus comprising a control member having a first surface for locating a workpiece during a machining operation, an outlet guide having a second surface for guiding a workpiece away from the control member;
