た。[Detailed Description of the Invention] The present invention uses high melting point gold such as tungsten and molybdenum #I! This relates to a method for cutting bars. - Conventionally, in order to accurately cut small-diameter high-melting point metal rods used as materials for electronic components into a certain length, a 9-jer cutting grindstone was used to cut the rods using a wet method.
The method used was to cut the books one by one while holding them by hand, or to cut multiple metal rods at the same time by enclosing and fixing them in resin or covering and fixing them with soft metal.

ストが高くなっていた。However, the method of cutting one piece at a time is extremely inefficient, and the method of fixing and cutting multiple pieces requires time for fixing and cutting, and even after cutting, there is no need to remove the fixing material. Special processes, equipment, chemicals, etc. are required, resulting in high costs.

ジノイドポンドのＧＣ砥粒であることが最も好ましい。The method for cutting high melting point metal rods according to the present invention involves counting in advance the number of high melting point metal rods that will form a stable regular hexagonal prism, bundling them into a bundle with a regular hexagonal cross section, and A synthetic resin tube such as vinyl is covered and heated, and the vinyl tube shrinks to fix the high-melting point metal rods into a hexagonal column-shaped bundle. It is characterized by The cut tube can be easily removed. If the cutting wheel is made of rubber, the heat generated during cutting will soften the rubber bonding material of the wheel, making the cutting dimension inaccurate. In addition, a whetstone using A abrasive grains has a sharp sharpness and generates a lot of heat, and the synthetic resin tube that is covered and fixed softens and loses its tightening effect, so it is most preferable to use resinoid pound GC abrasive grains. .

総本数をＮ、正六角形の一辺に並ぶ本数をｎとしたとき
次の式（１）が成りたつ。The number of metal rods arranged in a stable regular hexagonal column shape is determined by the following formula (1), where the total number of rods is N and the number of metal rods lined up on one side of the regular hexagon is n.
Ｎ ＝３ｎ（ｎ−１） ＋１・・・・・・・・・・・・

...(1) Also, the opposite side of the regular hexagon is J-law, and the rod diameter is d.
Then, formula (2) holds true, Cross = EL (2n -1) d...
(2) When cutting, the number of high-melting point metal rods to be bundled into a regular hexagonal column can be determined as long as the number satisfies formula (1), but n is between 3 and 1O. Preferably, the rod diameter is preferably in the range of 0.3 mm to 2.5 m+o.

最も安定し′こ形状の正六角柱に並ぶ。Next, the procedure for carrying out the present invention will be explained in more detail. First, the high melting point metal rod that you are going to cut is (1
), accurately count the number of pieces that are necessary and cover the pieces to form a regular hexagon, turn one cup to the east, and align the ends.
If you wrap a rubber band around it and repeatedly press it in with both hands, the sticks will be most stable and lined up like this regular hexagonal prism.
次いでＩＦ六角柱になった束の端部に例えば三菱樹脂製
熱収縮性塩化ビニールチューブ（商品名ヒシチューブ）
を被せ、熱風で加熱し、チューブを収縮させて仮固定す
る。Next, attach a heat-shrinkable vinyl chloride tube made by Mitsubishi Plastics (trade name Hishitube) to the end of the bundle that has become an IF hexagonal prism.
Cover the tube and heat it with hot air to shrink the tube and temporarily fix it.

角柱を連続して作って行き。After temporarily fixing, remove the rubber band, cover the entire body weight that is to be cut with the caliper tube, and squeeze the weight with both hands to fit the hexagonal column-shaped end that has been temporarily fixed above, and make a continuous hexagonal column. Go make it.

を虫ねてもよい。Deflate the tube and perform preliminary identification. After pre-fixing, correct any looseness, etc., and then pass it through a cylindrical band heater to fully contract the caltrop tube and securely fix it to the regular hexagonal column. Pass it through the band heater to ensure complete fixation. If an even stronger fixation is required, you can wrap the tube one more layer.
加熱に使用する円筒型バンドヒーターの加熱部の温度は
通常 １５０〜２００°Ｃ１被加熱体の通過速度は３〜
４ψｍ程度でよい。The temperature of the heating part of the cylindrical band heater used for heating is usually 150 to 200°C, and the passing speed of the heated object is 3 to 200°C.
Approximately 4ψm is sufficient.
