Description

Translated fromJapanese

この発明は、傷んだ切れ刃を再研磨によって再生して再利用する刃先交換式切削工具用の切削インサートに関する。  The present invention relates to a cutting insert for a cutting edge exchangeable cutting tool that regenerates and reuses a damaged cutting edge by regrinding.

切れ刃を単結晶ダイヤモンドなどの高価な材料で形成した刃先交換式切削工具用の切削インサートは、傷んだ切れ刃を再研磨により再生して高価な材料の有効利用を図ることが行われている。  Cutting inserts for cutting edge-exchangeable cutting tools whose cutting edges are made of an expensive material such as single crystal diamond are used to recycle the damaged cutting edges by regrinding and to make effective use of expensive materials. .

例えば、下記特許文献1には、切れ刃をダイヤモンドや立方晶型窒化硼素焼結体で形成した刃具を、刃振れ調整機構を具備した工具本体に装着して使用する回転切削工具が記載されており、この種の切削工具では、再研磨による切れ刃の再生が繰り返されている。  For example,Patent Document 1 listed below discloses a rotary cutting tool that uses a cutting tool whose cutting edge is formed of diamond or a cubic boron nitride sintered body and that is mounted on a tool body having a blade run-out adjusting mechanism. In this type of cutting tool, regeneration of the cutting edge by re-polishing is repeated.

特開2003−94225号公報JP 2003-94225 A

切れ刃を再生して使用する切削インサートについては、切削インサートが性能保証限界寸法に達するまでは再研磨を繰り返すことが行われているが、従来の再研磨式の切削インサートは、何回目の再研磨であるのか、どの位置まで研磨するのかなどがわからず、加工の段取りに時間がかかっているのが実情である。  For cutting inserts that are used by regenerating the cutting edge, regrinding is repeated until the cutting insert reaches the performance guarantee limit dimensions. Actually, it is difficult to know whether it is polishing or where it is polished, and it takes time to set up the processing.

この発明は、再研磨して使用する切削インサートについて、再研磨可能領域が何回分残っているかの確認や、再研磨位置の確認が容易にできるようにすることを課題としている。  It is an object of the present invention to make it possible to easily confirm how many re-polishing regions remain for a cutting insert to be used after re-polishing and to confirm the re-polishing position.

上記の課題を解決するため、この発明においては、台金と、この台金に貼り付けられた刃先チップとを有する切削インサートを、切れ刃と、線又は点が再研磨(による切れ刃再生)によって切れ刃位置が後退する方向に定ピッチで付された再研磨領域の表示目盛りを含むものにした。  In order to solve the above-described problems, in the present invention, a cutting insert having a base and a cutting edge tip attached to the base is re-polished with a cutting edge and a line or a point (by cutting edge regeneration). Thus, the display scale of the regrinding area marked with a constant pitch in the direction in which the cutting edge position is retracted is included.

この発明は、その切削インサートとこの切削インサートを装着する工具本体を含む回転切削工具も併せて提供する。  The present invention also provides a rotary cutting tool including the cutting insert and a tool body on which the cutting insert is mounted.

この発明の切削インサート及びそれを用いた回転切削工具は、再研磨可能領域が何回分残っているかと、再研磨をどの位置まで行うかを残存した目盛りによって確認することができる。  In the cutting insert of the present invention and the rotary cutting tool using the cutting insert, it is possible to check the number of remaining re-polishing regions and to what position the re-polishing is performed by the remaining scale.

以下、添付図面の図1〜図5に基づいて、この発明の切削インサートの実施の形態を説明する。  Embodiments of a cutting insert according to the present invention will be described below with reference to FIGS.

例示の切削インサート1は、台金2の上面の片方のコーナ部に、単結晶ダイヤモンド、焼結ダイヤモンド(PCD)、立方晶窒化硼素(CBN)などで形成された刃先チップ3を接合したものである。  The illustratedcutting insert 1 is obtained by joining acutting edge tip 3 formed of single crystal diamond, sintered diamond (PCD), cubic boron nitride (CBN) or the like to one corner of the upper surface of thebase metal 2. is there.

刃先チップ3には、切れ刃4が設けられている。例示の切れ刃4は、主切れ刃4aと、サラエ刃4bと、図2において主切れ刃4aの上端よりも上側にある予備領域4cを組み合わせた刃にしている。予備領域4cは、再研磨によって切れ刃位置が後退する方向に延びている。  Thecutting edge tip 3 is provided with acutting edge 4. The illustratedcutting edge 4 is a combination of amain cutting edge 4a, a Sarahblade 4b, and aspare region 4c located above the upper end of themain cutting edge 4a in FIG. Thepreliminary region 4c extends in a direction in which the cutting edge position is retracted by regrinding.

上記予備領域とは、再研磨による切れ刃の再生を可能となす領域を言う。  The preliminary area refers to an area where the cutting edge can be regenerated by regrinding.

その切れ刃4を備えた刃先チップ3は、図1において上を向いた面がすくい面3aとして使用される。  Thecutting edge tip 3 provided with thecutting edge 4 is used as arake face 3a with the surface facing upward in FIG.

この切削インサート1は、刃先チップ3に高価な材料を用いているので、性能保証限界寸法に達するまで再研磨による切れ刃再生を繰り返して使用される。  Since thiscutting insert 1 uses an expensive material for theblade tip 3, the cutting blade is repeatedly regenerated by re-polishing until reaching the performance guarantee limit dimension.

この切削インサート1には、再研磨の各回の研磨位置を示す目盛り5が施されている。例示の切削インサートの目盛り5は、切れ刃の前記予備領域4cに対して垂直な線を再研磨によって切れ刃位置が後退する方向に定ピッチで複数(再研磨の許容回数と同数)付して形成されているが、目盛り5は図示の形態のものに限定されない。  Thecutting insert 1 is provided with ascale 5 indicating the polishing position of each re-polishing. As for thescale 5 of the illustrated cutting insert, a line perpendicular to thepreliminary region 4c of the cutting edge is attached at a constant pitch in the direction in which the cutting edge position is retracted by re-polishing (the same number as the allowable number of re-polishing). Although it is formed, thescale 5 is not limited to the illustrated form.

1回毎の再研磨位置がわかる目盛りであればよい。線に代えて目印となる点を再研磨によって切れ刃位置が後退する方向に定ピッチで必要数付して目盛りとすることもできる。  Any scale may be used as long as it indicates the re-polishing position for each time. Instead of the line, a necessary number of points can be used as a scale in a direction in which the cutting edge position moves backward by regrinding at a constant pitch.

また、1回当たりの再研磨代と同じ長さの前記予備領域4cと平行な線の複数本を、互いが連ならないように位置をずらしながら再研磨によって切れ刃位置が後退する方向に配列して目盛りとすることもできる。  Further, a plurality of lines parallel to thespare region 4c having the same length as the re-polishing allowance per time are arranged in a direction in which the cutting edge position is retracted by re-polishing while shifting the position so as not to be connected to each other. It can also be used as a scale.

要は、1回毎の再研磨領域を確認でき、さらに、各回の再研磨によって目盛りの残存数が減少し、残存した目盛りの数から再研磨の残存回数を確認しうるものであればよい。  In short, it is only necessary to be able to confirm the re-polishing region for each time, and further to reduce the number of remaining scales by each re-polishing and to confirm the remaining number of re-polishing from the number of remaining scales.

図示の目盛り5は、レーザマーキングによって付したものであるが、機械加工したものであってもよい。  Thescale 5 shown in the figure is attached by laser marking, but may be machined.

例示の切削インサートの目盛り5は、台金2の表面の再研磨によって削り取られる領域に施されている。図示の目盛り5は、1目盛りが1回分の研磨代を表している。この目盛り5は、台金2の側面や刃先チップのすくい面3aに施すことも可能である。  Thescale 5 of the illustrated cutting insert is provided in an area that is scraped off by regrinding the surface of thebase metal 2. Thescale 5 shown in the figure represents a polishing allowance for one scale. Thescale 5 can also be applied to the side surface of thebase metal 2 or therake surface 3a of the cutting edge tip.

切れ刃再生のための再研磨は、基本的には1回の再研磨で1目盛り分の研磨代が除去されるように行う。研磨面が目盛り5の表示点と重なるところを各回の再研磨の完了位置とすれば、過剰研磨が起こらない。  The re-polishing for cutting edge regeneration is basically performed so that the polishing allowance for one scale is removed by one re-polishing. If the polishing surface overlaps with the display point of thescale 5 as the completion position of each re-polishing, excessive polishing does not occur.

目盛り5を構成する線や点は、再研磨が繰り返される毎に残存数が減少していく。従って、その線や点がいくつ残されているかで、再研磨の可能残存回数を知ることができる。  The number of remaining lines and points constituting thescale 5 decreases every time re-polishing is repeated. Therefore, the number of remaining re-polishings can be determined by how many lines and points are left.

また、1回の再研磨で1目盛り分の研磨代を除去すれば再研磨を何回行ったかも知ることができる。  In addition, it is possible to know how many times re-polishing has been performed by removing the polishing allowance for one scale in one re-polishing.

図示の切削インサート1の目盛り設置点は、切削加工時に発生する切屑の擦過が起こらない領域が選択されており、切屑の擦過による目盛り5の消失は起こらない。  As the scale setting point of thecutting insert 1 shown in the figure, a region where the scraping of chips generated during the cutting process does not occur is selected, and the disappearance of thescale 5 due to the scraping of the chips does not occur.

なお、刃先の損傷の程度によっては、1回の再研磨で複数目盛り分の研磨代を除去することがあり得る。従って、目盛り5は、再研磨の完了済み回数を知るための目盛りとしては万全のものとは言えないが、線や点の残存数からあと何回再研磨が可能であるかは確実に知ることができる。  Depending on the degree of damage to the blade edge, the polishing allowance for a plurality of scales may be removed by one re-polishing. Therefore, thescale 5 is not perfect as a scale for knowing the number of re-polishing completed, but it is sure to know how many times re-polishing is possible from the remaining number of lines and points. Can do.

図示の切削インサート1は、回転切削工具に利用される。その切削インサート1を採用した回転切削工具の一例を図6〜図8に示す。  The illustratedcutting insert 1 is used for a rotary cutting tool. An example of the rotary cutting tool which employ | adopted thecutting insert 1 is shown in FIGS.

例示の回転切削工具10は、仕上げ加工用の正面フライスカッタであって、工具本体11に切削インサート1を複数装着して構成されている。  The illustratedrotary cutting tool 10 is a face milling cutter for finishing, and is configured by mounting a plurality ofcutting inserts 1 on atool body 11.

工具本体11の先端外周には、周方向に所定の間隔をあけて切屑ポケット12と、各切屑ポケットに面したインサート支持座13が設けられている。  Achip pocket 12 and aninsert support seat 13 facing each chip pocket are provided on the outer periphery of the tip end of thetool body 11 at a predetermined interval in the circumferential direction.

また、切削インサート1を固定するクランプ機構14と、切れ刃4の工具軸方向位置を調節する刃振れ調整機構15が設けられている。  Further, aclamp mechanism 14 for fixing thecutting insert 1 and a bladerunout adjusting mechanism 15 for adjusting the position of thecutting edge 4 in the tool axis direction are provided.

その工具本体11の各インサート支持座13に、図1〜図5に示した切削インサート1が、刃先チップ3の図2に現れた面がすくい面、刃先チップ3の切れ刃4が主切れ刃4aとサラエ刃4bを構成する姿勢にして装着されている。  Thecutting insert 1 shown in FIGS. 1 to 5 is a rake face on theinsert support seat 13 of thetool body 11 and thecutting edge 4 of thecutting edge tip 3 is a main cutting edge. 4a and Saraeblade 4b are mounted in a posture.

そして、それぞれの切削インサート1が、クランプ機構14によって工具本体11に固定されている。  Eachcutting insert 1 is fixed to thetool body 11 by aclamp mechanism 14.

図示のクランプ機構14は、楔14aを工具本体11の楔溝に引き込んでその楔14aで切削インサート1を押圧固定する周知の機構である。  The illustratedclamping mechanism 14 is a known mechanism that pulls thewedge 14a into the wedge groove of thetool body 11 and presses and fixes thecutting insert 1 with thewedge 14a.

楔14aは、工具本体11にねじ込まれる一端側と、楔14aにねじ込まれる他端側に逆ねじを切ったいわゆるWねじ14bによって楔溝に引き込まれるものが設けられている。  Thewedge 14a is provided with a so-calledW screw 14b having a reverse thread on one end side screwed into thetool body 11 and the other end side screwed into thewedge 14a.

刃振れ調整機構15は、調整ねじ15aの一端を位置基準面にして切削インサート1に当接させ、その調整ねじ15aの工具本体11に対するねじ込み量を変化させることで位置基準面を工具軸方向に変位させて刃振れを調整するものであって、これも周知の機構である。  The blade run-outadjusting mechanism 15 uses one end of the adjustingscrew 15a as a position reference surface to contact thecutting insert 1, and changes the screwing amount of the adjustingscrew 15a into thetool body 11 to change the position reference surface in the tool axis direction. Displacement is used to adjust blade runout, which is also a well-known mechanism.

その刃振れ調整機構15を有する切削工具は、回転工具、非回転工具を問わず、切削インサートの刃振れ調整方向の寸法変化を刃振れ調整機構15によって吸収することができる。そのために、再研磨によって切れ刃を再生した切削インサートを使用することができる。  The cutting tool having the blade run-outadjusting mechanism 15 can absorb the dimensional change in the blade run-out adjustment direction of the cutting insert by the blade run-outadjusting mechanism 15 regardless of whether it is a rotating tool or a non-rotating tool. Therefore, a cutting insert in which the cutting edge is regenerated by regrinding can be used.

なお、この発明を適用する切削インサートは、図示の形状に限定されない。また、図示の回転切削工具に設けたクランプ機構とは構造の異なるクランプ機構で工具本体に固定されるものであってもよいし、台金にクランプねじなどが挿通される取付け孔を設けたものなどであってもよい。  Note that the cutting insert to which the present invention is applied is not limited to the illustrated shape. Also, the clamp mechanism provided in the illustrated rotary cutting tool may be fixed to the tool body by a clamp mechanism having a different structure, or provided with an attachment hole through which a clamp screw or the like is inserted. It may be.

さらに、その切削インサートは、刃振れ調整機構を有する刃先交換式切削工具の全てに利用することができる。  Furthermore, the cutting insert can be used for all cutting edge-exchangeable cutting tools having a blade run-out adjusting mechanism.
