Description
(試験例)
実施例のカッター１０と比較例のカッターとについて、実際にワーク(アルミナ含有ガラスエポキシ材からなるプリント基板)Ｗに、深さ０．５ｍｍのＶ字状の溝Ｗａを切削加工する試験を行い、両者の耐久性を比較した。実施例のカッター１０および比較例のカッターは、外径(直径)が１２０ｍｍで、歯数が２４個に設定され、厚さ２ｍｍの炭素工具鋼からなる台金１２の外周部に設けられた歯体１４の夫々にチップ２０,５０が接合された、チップソーとも呼ばれるものである。実施例のチップ２０および比較例のチップ５０は、超硬合金からなる基層に、多結晶ダイヤモンド(ＰＣＤ：４０μｍ＋１６μｍの混合粒)からなる表層が積層された複合材である。実施例のチップ２０に設けられた切削刃２２は、各利き刃３２のアサリ角が−１７．５°で(先端のＶ角度：３５°)、刃先３０を構成するすくい面２８のすくい角が−１５°で、該すくい面２８のリード角が１０°に設定されている。実施例の切削刃２２は、外周逃げ面２６が２段で形成されており、刃先３０を構成する第１の外周逃げ面２６Ａの延在長さが０．２ｍｍで、その外周逃げ角γ１が１°に設定されると共に、第１の外周逃げ面２６Ａに連なる第２の外周逃げ面２６Ｂの外周逃げ角γ２が１０°に設定されている。比較例のチップ５０(図６参照)は、各側面５２のアサリ角が−１７．５°で(先端のＶ角度：３５°)、刃先を構成するすくい面５４のすくい角が＋５°で、該すくい面５４のリード角が０°に設定されている。すなわち、比較例のチップ５０は、リードが設定されていない。比較例のチップ５０は、外周逃げ面５６が１段で形成されており、刃先を構成する外周逃げ面５６の外周逃げ角が１０°に設定されている。実施例のカッター１０および比較例のカッターを加工装置に夫々セットし、回転数等の加工条件を同じに設定して、前記ワークＷにＶ字状の溝Ｗａを切削したところ、実施例のカッター１０は比較例のカッターと比べて１０倍の耐久性を有していることが確認された。
(Test example)
About the cutter 10 of the example and the cutter of the comparative example, a test for actually cutting a V-shaped groove Wa having a depth of 0.5 mm is performed on a work (printed substrate made of an alumina-containing glass epoxy material) W. The durability of both was compared. The cutter 10 of the example and the cutter of the comparative example have an outer diameter (diameter) of 120 mm, the number of teeth is set to 24, and teeth provided on the outer peripheral portion of the base metal 12 made of carbon tool steel having a thickness of 2 mm. This is also called a chip saw in which the chips 20 and 50 are joined to each of the bodies 14. The chip 20 of the example and the chip 50 of the comparative example are composite materials in which a surface layer made of polycrystalline diamond (PCD: mixed particles of 40 μm + 16 μm) is laminated on a base layer made of cemented carbide. Cutting blade 22 provided on the chip 20 of the embodiment, clam angle of each handed blades 32 - in 17.5 ° (V angle of the tip: 35 °), the rake angle of the rake face 28 constituting a cutting edge 30 At -15 °, the lead angle of the rake face 28 is set to 10 °. In the cutting blade 22 of the embodiment, the outer peripheral flank 26 is formed in two stages, the extending length of the first outer flank 26A constituting the cutting edge 30 is 0.2 mm, and the outer flank angle γ1 is In addition to being set to 1 °, the outer peripheral clearance angle γ2 of the second outer peripheral clearance surface 26B connected to the first outer peripheral clearance surface 26A is set to 10 °. Comparative Example chip 50 (see FIG. 6) is, clam angle of each side 52 - 17.5 at ° (V angle of the tip: 35 °), with rake angle + 5 ° for the rake face 54 constituting a cutting edge, The lead angle of the rake face 54 is set to 0 °. That is, the lead of the chip 50 of the comparative example is not set. The tip 50 of the comparative example has an outer peripheral flank 56 formed in a single stage, and the outer peripheral flank angle of the outer peripheral flank 56 constituting the cutting edge is set to 10 °. When the cutter 10 of the example and the cutter of the comparative example were respectively set in the processing apparatus, the processing conditions such as the number of rotations were set to be the same, and the V-shaped groove Wa was cut into the workpiece W, the cutter of the example 10 was confirmed to be 10 times more durable than the cutter of the comparative example.
