Abstract

PURPOSE:To improve the finishing accuracy of the sliding face of a cock, improve the degree of matching and improve durability by pressing and rotating plural rollers to the sliding face of a gas cock, etc., and rolling the rollers. CONSTITUTION:A female roller tool 7 which holds parallel rollers 10 rollably along a female taper element 9 is fitted over the sliding face 3 of the closing member 1 of a cock and is rotated while being given pressure in the axial direction. By so doing, the rollers 10 roll on the sliding face crushing or dropping crests on the surface, therefore, the surface is mirror-finished. Similarly, the sliding face 4 is finished with the rollers 12 of a male roller tool 8. By so doing, the roughness accuracy, roundness and linearity of the sliding members 3, 4 can be improved and at the same time conformity factor and durability can be improved.
