本考案はスローアウエイ式のフライスカツタに
関するものである。[Detailed Description of the Invention] The present invention relates to a throw-away type milling cutter.
従来のこの種のフライスカツタにおいて、第2
図のように切屑aが排出されるチツプ押え金cの
スクイ面d上に段差bを設けたり、これにメツキ
したものがあるが、これでは排出される切屑aが
スクイ面d上で全面当りとなり、切削抵抗が大き
くなつていた。図面中eはチツプである。 In this type of conventional milling cutter, the second
As shown in the figure, there are chips that have a step b on the rake surface d of the chip presser c from which the chips a are discharged, or are plated. As a result, cutting resistance increased. In the drawing, e is a chip.
本考案は上記の事情に鑑みなされたものであつ
て、その目的とするところは、切屑とスクイ面と
の接触面積を小さくして切削抵抗を減少させるこ
とにある。 The present invention was developed in view of the above circumstances, and its purpose is to reduce the cutting resistance by reducing the contact area between the chips and the rake surface.
以下、本考案を第4図以下を参照して説明す
る。 Hereinafter, the present invention will be explained with reference to FIG. 4 and subsequent figures.
図面中1は本体であり、この本体1の外周面部
には周方向に一定の間隔をおいて複数個の装着部
2が形成してある。これら装着部2にはシキ板
3、チツプ4およびチツプ押え金5が設けてあ

1に締着してあり、チツプ押え金5でチツプ4を
押えてチツプ4が固定してある。チツプ押え金5
の上面はスクイ面6になされていてこのスクイ面
6に切屑流れに沿つて複数本の溝7が形成してあ
る。これら溝7の幅は、隣り合う溝7の間隔より
小さくしてある。なお、9はロケータである。 Reference numeral 1 in the drawings indicates a main body, and a plurality of mounting portions 2 are formed on the outer peripheral surface of the main body 1 at regular intervals in the circumferential direction. These mounting parts 2 are provided with a chip plate 3, a chip 4, and a chip presser foot 5. The chip presser foot 5 is fastened to the main body 1 by a clamp screw 8, and the chip presser foot 5 presses the chip 4. Chip 4 is fixed. Tip presser foot 5
The upper surface thereof is formed into a rake surface 6, and a plurality of grooves 7 are formed on this rake surface 6 along the flow of chips. The width of these grooves 7 is made smaller than the interval between adjacent grooves 7. Note that 9 is a locator.
しかして、本体1を回転してチツプ4でワーク
を切削したとき、切屑10はスクイ面6に沿つて
移動するが、このときスクイ面6に複数の溝7が
あるために切屑10とスクイ面6との接触面積が
少なくなり切削抵抗が少なくなる。 When the main body 1 is rotated and the tip 4 cuts a workpiece, the chips 10 move along the scoop surface 6, but at this time, since the scoop surface 6 has a plurality of grooves 7, the chips 10 and the scoop surface Since the contact area with 6 is reduced, the cutting resistance is reduced.
本体1の装着部2におけるチツプ4の装着が第
6図および第7図のようになされてチツプ4の後
方にスクイ面6が形成された場合このスクイ面6
に前記溝7が形成される。 When the tip 4 is attached to the attachment portion 2 of the main body 1 as shown in FIGS. 6 and 7 and a scoop surface 6 is formed at the rear of the tip 4, this scoop surface 6
The groove 7 is formed in the groove 7.
本考案は以上詳述したように、本体1の装着部
2に装着されたチツプ4の後方のスクイ面6に切
屑流れに沿う複数本の溝7を形成し、これら溝7
の幅を、隣り合う溝7の間隔より小さくしたこと
を特徴とするものである。 As described in detail above, the present invention forms a plurality of grooves 7 along the flow of chips on the rear scoop surface 6 of the chip 4 mounted on the mounting part 2 of the main body 1, and these grooves 7
The width of the grooves 7 is smaller than the interval between adjacent grooves 7.
したがつて、チツプ4により切削されて生じた
切屑10はスクイ面6を移動するとき、必ずスク
イ面6をすべり、この切屑10とスクイ面6との
接触面積が複数本の溝の分だけ小さくなつて切屑
抵抗を減少させることができる。 Therefore, when the chips 10 generated by cutting with the chip 4 move on the rake surface 6, they always slide on the rake surface 6, and the contact area between the chips 10 and the rake surface 6 is reduced by the amount of the plurality of grooves. As a result, chip resistance can be reduced.
