Method and apparatus for making a fixed abrasive wire
A method and apparatus for making a fixed abrasive grain wire includes, at first, inserting a wire through a sleeve that includes at least one aperture defined therein. Then, both of the wire and the sleeve are located in electroplating or electro-less plating liquid that includes abrasive grains blended therein. Finally, electroplating or electro-less plating is executed to fix some of the abrasive grains to the wire.
1. A method for making a fixed abrasive wire including the steps of:
inserting a wire 130 through a sleeve 110 including at least one aperture 160 defined therein;
locating the wire 130 and the sleeve 110 in electroplating liquid 170 including abrasive grains 180 blended therein; and
executing electroplating to fix some of the abrasive grains 180 to the wire 130 .
2. The method according to claim 1 , wherein the sleeve 110 includes at least one open end 220 in a shape selected from the group consisting of circular, oval, triangular and rectangular.
3. The method according to claim 2 , wherein the open end 220 of the sleeve 110 is circular, and the diameter thereof is 1 to 20 mm.
4. The method according to claim 1 , wherein the aperture 160 is in a shape selected from the group consisting of circular, oval, triangular and rectangular.
5. The method according to claim 4 , wherein the aperture 160 is circular, and the diameter thereof is 0.05 to 10 mm.
6. The method according to claim 1 , wherein the abrasive grains 180 are made of a material selected from the group consisting of silicon carbide, baron carbide, tungsten carbide, baron nitride, diamond, aluminum oxide, zirconium oxide and quartz.
7. The method according to claim 1 , wherein the abrasive grains 180 are spherical, and the diameter thereof is 1 to 60 μm.
8. The method according to claim 1 , wherein the sleeve 110 is located in a manner selected from the group consisting of vertical, horizontal and inclined.
