Abstract
PURPOSE: To comparatively inexpensively produce excellent and sharp scissors by providing a process for forming a hard substance layer on the blade surface of the scissors at a rubbing surface side by means of micro-welding and a process for smoothing the surface of the hard substance layer. CONSTITUTION: Hard substance 2 is made to be adjacent to the blade surface 1a on the rubbing surface being in the recessed surface shape of a sord blade 1 at interval of several μm, electric discharge is executed on the both opposed surfaces and hard substance 2 is firmly welded and coated on the blade surfaces 1a by micro-welding through the use of a laser, etc. At this time, a way for giving discharge energy in terms of a time and the way for giving discharge energy in terms of a position and a time with respect to the respective parts of a blade tip are precisely set and controlled since the blade tip part of the scissors is small and thin in a dimension and a shape with small thermal capacitance. Then, welded and coated hard substance 2 is ground together with the blade tip part of the sord blade 1 so as to be smoothed, tightly adhered to the blade surface of the other sord blade which is produced in the same way so as to be assembled by rubbing. At the time of wear, the rubbing surface and the opposite side blade surface are ground so as to be reproduced.
