Abstract

PURPOSE:To obtain a gap forming face with flaws reduced in mirror face polishing of the magnetic core half material, by forming grooves on the opposite face of the magnetic core half material. CONSTITUTION:A pair of grooves 11 and 12 and grooves 13 and 14 are formed in the opposite side of the magnetic core half material. In this magnetic core half material, the part surrounded by these grooves, namely, the gap forming face is polished, and it is cut along these grooves and is formed into prescribed dimensions. The influence of dust in air and falling powder is suppressed due to the effect of dust gathering of grooves by polishing the part surrounded by grooves, and thus, a mirror face with flaws reduced is obtained.
