A flavor inhalation pipe includes a hollow cylindrical pipe body (), a tobacco cartridge () accommodated, as a flavor generation cartridge, in the pipe body (), a mouthpiece () coupled to the tobacco cartridge () and projecting from the pipe body (), and a coupling device () coupling the pipe body () and the mouthpiece () to each other. The coupling device () has a coupling position in which the mouthpiece () is pressed against the pipe body () with a predetermined urging force to elastically coupled the two, and a release position which is assumed after the mouthpiece () in the coupling position is pushed into the pipe body () and then rotated and in which the coupling of the mouthpiece () to the pipe body () is released.

There is provided a conductive grinding wheel rotating centering on a vertical shaft center and including a horizontal working surface , and the grinding wheel comprises a conductive base member formed of an integrally molded flat plate, and a plurality of fan-shaped segments detachably attached to the base member to entirely constitute the annular working surface. Each segment comprises a base metal directly attached to the base member and a grinding wheel part formed on the surface of the base metal. Moreover, the grinding wheel part comprises a recessed groove for partitioning the working surface into a plurality of working areas , and an electrolytic fluid supply hole for directly supplying the electrolytic fluid to the respective working areas, so that the electrolytic fluid is supplied to the respective electrolytic fluid supply holes through the base member.

A metal bond grinding wheel,having a horizontal working surface,a holding and rotating means,for a workpiece having a horizontal supporting surface,opposite to said working surface,a voltage applying means,having the metal bond grinding wheels and an electrode,installed oppositely to the working surfaces in an uncontacted state and applying a pulsed voltage between them, a grinding fluid feeding means,for feeding an electroconductive grinding fluid to the working surfaces are installed. The holding and rotating means,holds and rotate a disk-like magnetic disc substrate,or a truing grinding wheel,to closely contact to its supporting surface, has constitution capable of moving horizontally and vertically, wherein a surface for working,is processed to yield a flat surface on the machine, subsequently, alternative operations on the machine are carried out for grinding of the supporting surface,of the holding and rotating means of the workpiece simultaneously with electrolytic dressing of the metal bond grinding wheel and grinding of the magnetic disc substrate,attached to the holding and rotating means of the workpiece.
