Abstract

PURPOSE:To smooth the lubrication thereof even though it is operated under the contact with a scroll tooth by a method wherein the roughness of the surface of a scroll groove section is improved by effecting the burnishing work of the scroll groove section after the cutting work of the scroll member. CONSTITUTION:A round table 8, secured to a milling machine bed 9, is formed so as to be rotated under synchronizing with the parallel advancement in X direction of the milling machine bed 9 perfectly while a clutch 11 is provided to make them operable independently respectively for the convenience of the working. Then, a cutting edge 7 is employed as shown by the diagram and cut a circular involute groove as a fixed scroll 1 to be worked is advanced in parallel under being rotated, thereafter, the cutting edge 7 is exchanged to a burnishing tool, the cylindrical end face of which has a plane 7a vertical with respect to the axial line thereof, an angle 7b of which is steep, the face 7a of which shows a cross shape having a groove 7c, and the cylindrical side face section of which has a plurality of U-shaped grooves 7d in parallel with the axial line thereof. According to this method, the surface roughness of the scroll groove section is improved and the lubrication thereof may be smoothened.
