PROBLEM TO BE SOLVED: To provide a single layer fixed abrasive grain wire saw having a narrow and approximately uniform wire diameter, making a kerf width small in cutting, providing a cutting face with superior face accuracy as a result of the cutting and improving the yield of the material and the working efficiency, and also to provide a cutting method for ingot. SOLUTION: This single layer fixed abrasive grain wire saw is manufactured such that pretreatment processes using an immersed degreasing tank, an acid immersed tank and a rinsing tank are performed, while feeding a highly rigid core wire 1 at a fixed speed, adhesive is dottedly and approximately uniformly applied on the outer circumferential face of the core wire 1 with an adhesive applicator to form an adhesive part 2b, and then abrasive grains 2a are temporarily fixed on the adhesive part 2b into a single layer. Lastly, the abrasive grains 2a are regularly fixed by electrolytic plating to provide the single layer fixed abrasive grain wire saw. COPYRIGHT: (C)2004,JPO&NCIPI |
