Description

この発明は、刃振れ調整機構を有する正面フライスや隅削りフライスなどの回転切削工具に関する。   The present invention relates to a rotary cutting tool such as a face mill and a corner milling cutter having a blade runout adjustment mechanism.

仕上げフライス加工では、高精度の刃先位置精度が要求される。各刃の振れ精度が悪いと、仕上げ面粗さの悪化、加工中のいわゆるびびり、ばりの発生、工具寿命の短縮などの弊害が出る。   In finishing milling, high precision edge position accuracy is required. If the runout accuracy of each blade is poor, adverse effects such as deterioration of the roughness of the finished surface, so-called chatter during processing, occurrence of flash, and shortening of the tool life will occur.

そこで、スローアウェイカッタ用の刃振れ調整機構が種々考案されている。その刃振れ調整機構に関する文献としては、例えば、下記特許文献１〜４などがある。
特開２００１−２５２８１３号公報 実開平７−２７７１９号公報 実用新案登録第３０６４３２４号 特表２００２−５１６７６２号公報 Therefore, the blade deflection adjusting mechanism for Slow-away cutter is devised. Examples of documents relating to the blade runout adjustment mechanism include the following Patent Documents 1 to 4.
Japanese Patent Laid-Open No. 2001-252813 Japanese Utility Model Publication No. 7-27719 Utility model registration No. 3064324 JP-T-2002-516762

特許文献１の正面フライスは、スローアウェイチップ（以下単にチップとも云う）の背面と工具中心側の側面を工具本体の先端外周に設けたチップ取付け座に着座させ、チップの工具基端側の側面を調整ねじで押し動かす押圧ピンで受ける構造にしている。しかしながら、押圧ピンが工具軸方向に動くこの構造では、チップの工具軸方向の位置基準が定まらず、チップを交換したり切れ刃の位置を入れ替えたりする度に全てのチップについて刃振れ調整を行なう必要があり、調整時間が長くなる。類似の調整機構として楔のテーパ面を変位させてチップを工具軸方向に迫り出させるものもあるが、これも同様の欠点を有している。   The front milling of Patent Document 1 is such that the back surface of the throw-away tip (hereinafter also simply referred to as a tip) and the side surface on the tool center side are seated on a tip mounting seat provided on the outer periphery of the tip of the tool body, and the side surface on the tool proximal side of the tip Is configured to be received by a pressing pin that is moved with an adjusting screw. However, in this structure in which the pressing pin moves in the tool axis direction, the position reference of the chip in the tool axis direction is not fixed, and the blade runout adjustment is performed for all the chips every time the chip is replaced or the position of the cutting edge is replaced. This requires adjustment time. There is a similar adjustment mechanism that displaces the taper surface of the wedge to cause the tip to protrude in the tool axis direction, but this also has the same drawbacks.

また、特許文献２のカッタは、楔で本体に固定する調整駒に弾性変形部を設けてその弾性変形部をチップの工具軸方向の位置基準とし、これを調整駒にねじ込んだボルトで弾性変形させて刃振れ調整を行なうようにしているが、この構造は、チップの後退を弾性変形部の弾性復元力で行なうので後退変位については信頼性がなく、調整がし難い。また、降伏点を越した弾性変形部の変形や長期使用による弾性変形部の疲労が考えられ、それにより、弾性変形部が元に戻らなくなったり破損したりする虞もある。   Further, the cutter of Patent Document 2 is provided with an elastic deformation portion on an adjustment piece fixed to the main body with a wedge, and the elastic deformation portion is used as a position reference in the tool axis direction of the tip, and this is elastically deformed with a bolt screwed into the adjustment piece. In this structure, since the tip is retracted by the elastic restoring force of the elastic deformation portion, the backward displacement is not reliable and is difficult to adjust. In addition, deformation of the elastically deformable portion beyond the yield point and fatigue of the elastically deformable portion due to long-term use can be considered, and thereby the elastically deformable portion may not return to its original state or may be damaged.

さらに、特許文献３、４が開示している溝フライスの刃振れ調整機構は、チップを装着するポケット（刃溝）壁の一部を弾性変形可能となし、その一部のポケット壁を調整ねじの力を受けるボールで加圧して弾性変形させ、壁面に接したチップの刃先を変位させるようにしているが、これも特許文献２の弾性変形部と同様、ポケット壁の復元に関する信頼性に欠ける。変形が残ってポケット壁が元の位置に完全に戻らなかった場合、次回の刃振れ調整では前回と同じ調整量を確保するために余分な加圧が必要になり、これが繰り返されるとついには降伏点を越えてポケット壁が復元不能になったり、破損したりする可能性がある。   Further, in the groove milling blade run-out adjustment mechanism disclosed in Patent Documents 3 and 4, a part of a pocket (blade groove) wall on which a chip is mounted can be elastically deformed, and a part of the pocket wall is adjusted with an adjusting screw. The tip of the tip that is in contact with the wall surface is displaced by being pressurized and elastically deformed with a ball that receives the force of this force, but this also lacks the reliability related to the restoration of the pocket wall, like the elastically deformed portion of Patent Document 2. . If the deformation remains and the pocket wall does not return to its original position, the next blade runout adjustment will require extra pressure to ensure the same amount of adjustment as before, and if this is repeated, it will eventually yield. Beyond that point, the pocket wall can become unrecoverable or damaged.

加えてこの構造は、弾性変形させる部位の厚みを厳密に管理しないと弾性変形のための加圧力が各刃毎に変化し、従って、非常に高度な難度の高い加工が強いられ、加工時間等も多く費やすことになる。   In addition, if the thickness of the part to be elastically deformed is not strictly controlled, the pressure applied for elastic deformation changes for each blade, and therefore a very high degree of difficult processing is required, and the processing time, etc. Will spend too much.

また、従来の刃振れ調整機構付きカッタは、荒加工時にチップに加わる負荷を調整機構で受けるとチップ固定の信頼性が不十分になり、また、軸方向基準面（変位可能な面）の位置がばらつくため、荒加工に利用する場合にも基準面の位置調整を強いられるケースが出てくるなどの問題があり、荒加工には適していなかった。   In addition, the conventional cutter with blade run-out adjustment mechanism is not reliable enough to fix the tip when the adjustment mechanism receives the load applied to the tip during rough machining, and the position of the axial reference surface (displaceable surface) Therefore, there are cases where the reference plane position is forced to be adjusted even when used for roughing, which is not suitable for roughing.

この発明は、同一工具で荒加工と仕上げ加工を安定して行なえ、また、刃振れ精度が要求される場合には構造の簡単な機構で短時間に確実な調整が行なえるようにすることを課題としている。   This invention is capable of stably performing roughing and finishing with the same tool, and enabling accurate adjustment in a short time with a simple structure when blade runout accuracy is required. It is an issue.

上記の課題を解決するため、この発明においては、先端外周に複数の刃溝を設けたカッタ本体と、前記刃溝の各々に装着して切れ刃を構成するスローアウェイチップと、そのスローアウェイチップをカッタ本体に着脱自在に固定するクランプ手段と、各スローアウェイチップの刃振れ調整ねじとを備えさせて回転切削工具を構成した。また、各刃溝にはスローアウェイチップの背面と隣り合う２側面とを着座させてスローアウェイチップを工具回転方向、径方向および軸方向に位置決めする３つの座面を備えさせ、前記刃振れ調整ねじをカッタ本体の刃溝形成部に軸方向にねじ込み、この刃振れ調整ねじの一端を前記刃溝の軸方向位置決め用座面の位置から前後に変位させて刃溝の前記軸方向位置決め用座面によるスローアウェイチップの軸方向位置決めと刃振れ調整ねじの一端によるスローアウェイチップの軸方向位置決めを行えるようにした。   In order to solve the above-described problems, in the present invention, a cutter body having a plurality of blade grooves on the outer periphery of the tip, a throw-away tip that is attached to each of the blade grooves to form a cutting edge, and the throw-away tip thereof The rotary cutting tool is configured by including a clamping means for detachably fixing the cutter to the cutter body and a blade runout adjusting screw of each throw-away tip. Each blade groove is provided with three seating surfaces for positioning the throwaway tip in the tool rotation direction, radial direction and axial direction by seating the rear side of the throwaway tip and two adjacent side surfaces, and adjusting the blade runout Screw the screw into the blade groove forming part of the cutter body in the axial direction, and displace one end of this blade run-out adjusting screw back and forth from the position of the axial positioning seating surface of the blade groove to make the axial positioning seat of the blade groove Axial positioning of the throw-away tip by the surface and axial positioning of the throw-away tip by one end of the blade run-out adjusting screw can be performed.

この回転切削工具は、刃振れ調整ねじの頭部に当該ねじの回転操作部を設け、この回転操作部を外部に露出させて刃振れ調整ねじを頭部が前になる向きにしてカッタ本体に前側からねじ込み、この刃振れ調整ねじの頭頂面をスローアウェイチップの工具基端側の側面に当接させるようにしたものが好ましい。   This rotary cutting tool is provided with a rotation operation portion for the screw at the head of the blade runout adjustment screw, and the rotation runout portion is exposed to the outside so that the blade runout adjustment screw is directed to the front of the cutter. It is preferable that the screw is screwed in from the front side and the top surface of the blade run-out adjusting screw is brought into contact with the side surface of the throw-away tip on the tool proximal side.

この発明の回転切削工具は、刃溝の軸方向位置決め用座面と調整ねじを使い分けてスローアウェイチップの軸方向位置決めを行えるので、荒加工では刃振れ調整ねじを後退させてチップの位置決めを刃溝の座面で行い、仕上げ加工では刃振れ精度の悪いチップのみについて調整ねじを操作して軸方向の刃振れ調整を行なうことができる。   Since the rotary cutting tool of the present invention can perform the axial positioning of the throw-away tip by properly using the axial positioning seating surface of the blade groove and the adjustment screw, in rough machining, the blade run-out adjustment screw is retracted to position the tip. It is possible to adjust the blade runout in the axial direction by operating the adjusting screw only for the chip having a low blade runout accuracy in the finishing process.

この回転切削工具は、荒加工では刃先の位置決めが刃溝の座面によってなされ、調整機構による基準面の位置調整（基準面の位置のばらつきを吸収するための調整）を必要としない。また、チップの３面を刃溝で拘束するので、荒加工を安定して行なうことができる。   In this rotary cutting tool, in rough machining, the blade edge is positioned by the seat surface of the blade groove, and the position adjustment of the reference surface by the adjustment mechanism (adjustment for absorbing variations in the position of the reference surface) is not required. In addition, since the three surfaces of the chip are constrained by the blade groove, roughing can be performed stably.

一方、仕上げ加工では、刃溝の座面でチップを仮位置決めして刃振れを確認し、振れ精度の悪いチップがあればそのチップを調整ねじで変位させて刃振れを調整する。仮位置決め時に刃溝の座面が軸方向の位置基準になるため、最先端に位置する刃先に対して規定値を越えて後退している刃だけを調整ねじで前方に迫り出させればよく、全刃にわたって調整する必要がない。また、調整ねじを軸方向の位置基準となすので、弾性変形部材を用いるときに問題となる復帰の信頼性なども確保され、調整を短時間で確実に行なえる。調整ねじによる刃振れ調整であるので調整機構も複雑にならない。   On the other hand, in finishing, the tip is temporarily positioned on the seat surface of the blade groove to check the blade runout. If there is a tip with poor runout accuracy, the tip is displaced with an adjusting screw to adjust the blade runout. Since the seat surface of the blade groove serves as the axial position reference during temporary positioning, only the blade that has been retracted beyond the specified value with respect to the cutting edge located at the forefront needs to be pushed forward with the adjusting screw. There is no need to adjust over the entire blade. In addition, since the adjustment screw is used as the axial position reference, the reliability of the return, which is a problem when using the elastically deformable member, is ensured, and the adjustment can be performed reliably in a short time. Since the blade runout is adjusted by the adjusting screw, the adjusting mechanism is not complicated.

このほか、荒加工と仕上げ加工の両方に利用できるため、２種類のカッタを使用する必要がなく、経費削減、工具管理の面でも有利になる。   In addition, since it can be used for both roughing and finishing, it is not necessary to use two types of cutters, which is advantageous in terms of cost reduction and tool management.

以下、この発明の回転切削工具の実施形態を図１乃至図６に基づいて説明する。図１乃至図４は、第１実施形態を示している。この回転切削工具（図のそれは隅削りフライス）は、カッタ本体１と、スローアウェイチップ２と、このスローアウェイチップ２をカッタ本体１に固定するクランプ手段３と、刃振れ調整用の調整ねじ４とで構成されている。   Hereinafter, an embodiment of a rotary cutting tool of the present invention will be described with reference to FIGS. 1 to 6. 1 to 4 show a first embodiment. This rotary cutting tool (the corner milling cutter in the figure) includes a cutter body 1, a throw-away tip 2, clamp means 3 for fixing the throw-away tip 2 to the cutter body 1, and an adjustment screw 4 for adjusting blade run-out. It consists of and.

カッタ本体１の先端外周には、スローアウェイチップ２を装着する刃溝５が周方向に間隔を開けて複数設けられている。その刃溝５は、図４に示すように、チップを工具回転方向、径方向、軸方向の３方向に位置決めして拘束する３つの座面を備えるもの、即ち、スローアウェイチップ２の背面２ａを着座させる座面５ａと、工具中心側に置かれる側面２ｂを着座させる座面５ｂと、工具基端側に置かれる側面２ｃを着座させる座面５ｃを備えるものにしてある。   A plurality of blade grooves 5 for mounting the throw-away tip 2 are provided on the outer periphery of the tip end of the cutter body 1 at intervals in the circumferential direction. As shown in FIG. 4, the blade groove 5 is provided with three seating surfaces for positioning and restraining the tip in three directions of the tool rotation direction, the radial direction, and the axial direction, that is, the back surface 2a of the throw-away tip 2. , A seating surface 5b for seating the side surface 2b placed on the tool center side, and a seating surface 5c for seating the side surface 2c placed on the tool base end side.

クランプ手段３は、スローアウェイチップ２の中心穴に通して頭部を中心穴の入口部に係止させる皿頭のクランプねじ３ａと、座面５ａの位置に開けたねじ孔３ｂ（図４参照）とから成る。クランプねじ３ａをねじ孔３ｂにねじ込み、刃溝５の座面に着座させたスローアウェイチップ２をクランプねじ３ａで締めつけてカッタ本体１に固定するようにしている。なお、スローアウェイチップ２の中心穴とその穴に通すクランプねじ３ａとの間には、刃振れ調整に必要な隙間ｇ（図５参照）を生じさせている。   The clamping means 3 includes a countersunk head clamping screw 3a that passes through the center hole of the throw-away tip 2 and locks the head to the inlet of the center hole, and a screw hole 3b that is opened at the position of the seat surface 5a (see FIG. 4). ). The clamp screw 3a is screwed into the screw hole 3b, and the throw-away tip 2 seated on the seat surface of the blade groove 5 is fastened with the clamp screw 3a to be fixed to the cutter body 1. A gap g (see FIG. 5) necessary for blade runout adjustment is generated between the center hole of the throw-away tip 2 and the clamp screw 3a that passes through the hole.

調整ねじ４には、頭頂面４ａと頭部外周の双方にそれぞれ回転操作部（スパナ係合溝）４ｂ、４ｃを設けており、この調整ねじ４を頭部が前になる向きにしてカッタ本体１の刃溝形成部に前側から軸方向にねじ込み、ねじを回転させて頭頂面４ａを座面５ｃを切り欠いた位置から座面５ｃの前後に変位させられるようにしている。この調整ねじ４は、必要があれば工具の軸心に対して若干傾け、頭頂面４ａがスローアウェイチップ２の側面２ｃに密着するようにしておくのがよい。   The adjustment screw 4 is provided with rotation operation portions (spanner engagement grooves) 4b and 4c on both the top surface 4a and the outer periphery of the head, and the cutter body with the adjustment screw 4 facing forward. One blade groove forming portion is screwed in the axial direction from the front side, and the screw is rotated so that the top surface 4a is displaced from the position where the seat surface 5c is cut out to the front and back of the seat surface 5c. If necessary, the adjusting screw 4 is preferably slightly inclined with respect to the axis of the tool so that the top surface 4a is in close contact with the side surface 2c of the throw-away tip 2.

回転切削工具の刃振れは、刃先の位置誤差が１０μｍ以内、より好ましくは５μｍ以内に納まることが望まれ、調整ねじ４による刃振れ調整であればその要求に応えることができる。   It is desired that the blade runout of the rotary cutting tool be within a position error of 10 μm, more preferably within 5 μm, and the blade runout adjustment by the adjusting screw 4 can meet the demand.

このように構成した例示の回転切削工具は、各調整ねじ４の頭頂面４ａを座面５ｃから幾分か後退した位置に引き込んでおく。そして、この状態でスローアウェイチップ２を、そのチップの背面２ａと隣合う２側面２ｂ、２ｃを座面５ａ〜５ｃで位置決めして各刃溝５にセットし、チップの中心穴に通したクランプねじ３ａを締めつけてそのスローアウェイチップ２をカッタ本体１に固定する。座面５ｃによるスローアウェイチップ２の軸方向位置決めに支障がなければ、調整ねじ４の頭頂面４ａはチップの側面２ｃに接触していても差し支えない。   The exemplary rotary cutting tool configured in this manner draws the top surface 4a of each adjustment screw 4 to a position somewhat retracted from the seat surface 5c. In this state, the throwaway tip 2 is clamped by positioning the two side surfaces 2b and 2c adjacent to the back surface 2a of the tip with the seating surfaces 5a to 5c and setting them in the respective blade grooves 5, and passing them through the center hole of the tip. The screw 3 a is tightened to fix the throw-away tip 2 to the cutter body 1. If the axial positioning of the throw-away tip 2 by the seating surface 5c is not hindered, the top surface 4a of the adjusting screw 4 may be in contact with the side surface 2c of the tip.

荒加工は、この状態の工具を用いて行なう。また、仕上げ加工で高い刃振れ精度が要求される場合には、スローアウェイチップ２を３つの座面で５ａ〜５ｃで仮位置決めして刃溝５に取り付けた後、各刃の振れを確認する。そして、最先端の刃を基準にしてその基準刃よりも後退した位置にある刃をクランプを緩めて調整ねじ４で迫り出させ、刃振れが修正された位置で再クランプを行なう。振れが生じていない刃は調整の必要がなく、複数の刃の中の１枚のみ精度が悪ければ１刃のみの調整でよい。   Roughing is performed using the tool in this state. Further, when high blade runout accuracy is required in finishing, the throwaway tip 2 is temporarily positioned on three seating surfaces 5a to 5c and attached to the blade groove 5, and then the runout of each blade is confirmed. . Then, with the cutting edge as a reference, the blade at a position retracted from the reference blade is loosened with the clamp and pushed out by the adjusting screw 4, and re-clamped at the position where the blade runout is corrected. Adjustment is not necessary for a blade that does not shake, and only one blade may be adjusted if the accuracy of only one of the blades is poor.

図６は、クランプ手段３としてクランプ駒（楔）３ｃを用いた例を示す。スローアウェイチップ２を固定するクランプ手段は、推進ねじ３ｄで進退させる図示のクランプ駒などであってもよく、また、この発明は図６の正面フライスなどにも適用できる。   FIG. 6 shows an example in which a clamp piece (wedge) 3 c is used as the clamp means 3. The clamping means for fixing the throw-away tip 2 may be the illustrated clamping piece that is advanced and retracted by the propulsion screw 3d, and the present invention can also be applied to the front milling machine of FIG.

さらに、例示の工具は、調整ねじ４を工具の前側で操作するものにしたが、カッタ本体１の形状によっては調整ねじ４を本体の基端側（後部側）から操作可能となすことができる。   Furthermore, although the illustrated tool operates the adjusting screw 4 on the front side of the tool, the adjusting screw 4 can be operated from the base end side (rear side) of the main body depending on the shape of the cutter body 1. .

このほか、図１のスローアウェイチップ２は、母材にダイヤモンド焼結体２ｄを鑞付けしたものになっているが、使用するスローアウェイチップ２は、ダイヤモンド焼結体２ｄに代えてｃＢＮ焼結体を接合したものや図３に示す超硬チップなどであってもよく、特に限定されない。   In addition, the throw-away tip 2 in FIG. 1 is obtained by brazing a diamond sintered body 2d to a base material, but the throw-away tip 2 to be used is cBN sintered instead of the diamond sintered body 2d. What joined the body, the cemented carbide chip shown in FIG. 3, etc. may be sufficient and it does not specifically limit.
