Description
【０００１】[0001]
本考案は板状材を研削してドーナツ状の円板を抜き出す内・外径研削砥石に関 する。 The present invention relates to an inner / outer diameter grinding wheel for grinding a plate-shaped material to extract a donut-shaped disc.
【０００２】[0002]
光ディスク、磁気ディスク等に使用される円盤状のガラス板は、環状に配設さ れた砥石で加工されている。すなわち、ドーナツ状のガラス板を加工する場合、 矩形状のガラス板を１枚毎に加工テーブルに真空吸着させて、環状に配設された 砥石を回転させて、矩形状のガラス板から円盤状のガラス板を抜き出す。これに より、円盤状のガラス板が加工される。 Disk-shaped glass plates used for optical disks, magnetic disks, etc. are processed with a grindstone arranged in an annular shape. In other words, when processing doughnut-shaped glass plates, each rectangular glass plate is vacuum-adsorbed on the processing table and the circularly arranged grindstone is rotated to move the rectangular glass plate into a disc shape. Pull out the glass plate. As a result, a disk-shaped glass plate is processed.
【０００３】 しかしながら、円盤状のガラス板を１枚毎に加工するのでは、生産性の向上を 図ることができない。そこで、本件出願人は生産性の向上を図るために、図４に 示すように複数のガラス板１０、１０…を重ね合わせた状態で密着一体化し、こ の密着一体化された複数のガラス板１０、１０…を研削して複数のドーナツ状の ガラス板１０Ａ、１０Ａ…を抜き出す加工方法を考案した。この方法によれば、 一回の研削加工工程で複数のドーナツ状のガラス板１０Ａ、１０Ａ…を生産する ことができるので、ドーナツ状のガラス板１０Ａ、１０Ａ…の生産性が向上する 。However, if the disk-shaped glass plates are processed one by one, the productivity cannot be improved. Therefore, in order to improve the productivity, the applicant of the present invention tightly integrates a plurality of glass plates 10, 10, ... A processing method was devised in which a plurality of donut-shaped glass plates 10A, 10A ... According to this method, since a plurality of donut-shaped glass plates 10A, 10A ... Can be produced in one grinding process, the productivity of the donut-shaped glass plates 10A, 10A.
【０００４】[0004]
一方、研削砥石でドーナツ状のガラス板を生産する場合、研削部の冷却や切粉 の除去等の理由で研削部に研削液を供給する。しかしながら、複数のガラス板を 密着一体化すると厚みが増すので、研削部が深くなり、研削部に研削液を十分に 供給することができないという問題がある。 On the other hand, when a doughnut-shaped glass plate is produced with a grinding wheel, a grinding liquid is supplied to the grinding section for the purpose of cooling the grinding section or removing chips. However, when a plurality of glass plates are brought into close contact with each other and integrated, the thickness increases, so that the grinding portion becomes deep, and there is a problem that the grinding liquid cannot be sufficiently supplied to the grinding portion.
【０００５】 ところで、矩形状のガラス板からドーナツ状のガラス板を抜き出すための、内 径砥石と外径砥石を一体で備えた内・外径研削砥石は、図５に示すように、内径 砥石２０と外径砥石２２をシャフト２４に同軸上に固定されている。そして、内 径砥石２０と外径砥石２２はシャフト２４の回転で同一角速度で回転する。 しかしながら、外径砥石２２は内径砥石２０より半径が大きいので、外径砥石 ２２と内径砥石２０とを同一角速度で回転すると、図６に示すように外径砥石２ ２の周速( Ｖ1 ）が内径砥石２０の周速( Ｖ2 ）より速くなる。この影響もあっ て、外径砥石２２の摩耗量と内径砥石２０の摩耗量とに差が生じる。これにより 、一方の砥石がまだ使用できる状態でも一緒に交換されるので、砥石が無駄にな るという問題がある。By the way, an inner / outer diameter grinding wheel for integrally removing an inner diameter grindstone and an outer diameter grindstone for extracting a donut-shaped glass plate from a rectangular glass plate has an inner diameter grindstone as shown in FIG. 20 and an outer diameter grindstone 22 are coaxially fixed to a shaft 24. Then, the inner diameter grindstone 20 and the outer diameter grindstone 22 rotate at the same angular velocity as the shaft 24 rotates. However, since the outer diameter grindstone 22 has a larger radius than the inner diameter grindstone 20, when the outer diameter grindstone 22 and the inner diameter grindstone 20 are rotated at the same angular velocity, as shown in FIG. 6, the peripheral speed (V 1 ) of the outer diameter grindstone 22 is increased. Becomes faster than the peripheral speed (V 2 ) of the inner diameter grindstone 20. This influence also causes a difference in the wear amount of the outer diameter grindstone 22 and the wear amount of the inner diameter grindstone 20. As a result, even if one of the whetstones is still usable, it is replaced together, and there is a problem that the whetstone is wasted.
【０００６】 本考案はこのような事情に鑑みてなされたもので、密着一体化された複数のガ ラス板から複数の円盤状のガラス板を加工する際に、研削部に研削液を十分に供 給することができ、また、内径砥石と外径砥石とを別々に交換してそれぞれの研 削砥石を寿命まで使用することができる内・外径研削砥石を提供することを目的 とする。The present invention has been made in view of the above circumstances, and when processing a plurality of disc-shaped glass plates from a plurality of glass plates that are intimately integrated with each other, a grinding liquid is sufficiently supplied to the grinding portion. It is an object of the present invention to provide an inner / outer diameter grinding wheel that can be supplied and that can be used by exchanging the inner diameter wheel and the outer diameter wheel separately and using the respective grinding wheels for their respective lives.

The outer diameter grindstone grinds a plate-shaped material into a disk shape and the inner diameter grindstone described above. In an inner / outer diameter grinding wheel for processing a doughnut-shaped plate material by forming an opening hole in the center of a disk-shaped plate material, the outer diameter whetstone consists of a pair of whetstones, and the pair of whetstones are The grindstones are arcuately formed along an arc centered around the rotation axis of the grinding machine and are arranged to face each other, and the arcuate lengths of the pair of grindstones are the arcs other than the pair of outer diameter grindstones.

The arcuate lengths of the pair of grindstones were set such that the arc portions other than the pair of outer diameter grindstones were spaces capable of supplying the grinding fluid. Therefore, the grinding fluid can be supplied on the arc between the pair of arc-shaped grindstones.
【００１０】 また、本考案によれば、内径砥石を着脱自在に取り付けたので、内径砥石と外 径砥石を容易に分離することができる。Further, according to the present invention, since the inner diameter grindstone is detachably attached, the inner diameter grindstone and the outer diameter grindstone can be easily separated.
【００１１】[0011]
以下添付図面に従って本考案に係る内・外径研削砥石について詳説する。図１ には本考案に係る内・外径研削砥石３０の断面図が示されていて、図２にはその 底面図が示されてている。内・外径研削砥石３０はシャフト部３２、支持部３４ 及び砥石部３６から成り、シャフト部３２は研削装置（図示せず。）の回動軸に 着脱自在に取り付けられる。 The inner / outer diameter grinding wheel according to the present invention will be described in detail below with reference to the accompanying drawings. FIG. 1 shows a sectional view of an inner / outer diameter grinding wheel 30 according to the present invention, and FIG. 2 shows a bottom view thereof. The inner / outer diameter grinding wheel 30 comprises a shaft portion 32, a support portion 34, and a whetstone portion 36, and the shaft portion 32 is detachably attached to a rotary shaft of a grinding device (not shown).
【００１２】 シャフト部３２の下端には支持部３４が形成されている。すなわち、支持部３ ４は円板３４Ａを有し、円板３４Ａはシャフト部３２に同軸上に連結されている 。円板３４Ａ周縁には一対のフォーク３４Ｂ、３４Ｂが互いに対向して形成され ている。これにより、フォーク３４Ｂ、３４Ｂは図２に示すように円板３４Ａの 外周に沿って互いに対向して配置される。そして、フォーク３４Ｂは円板３４Ａ の外周に沿って弓形に形成されていて、この弓形の周長Ｌ1 は、フォーク３４Ｂ 以外の円板３４Ａの周縁部に研削液を供給可能なスペースとなるように設定され ている（例えば、図２上ではフォーク３４Ｂの弓形の周長Ｌ1 は、シャフト部３ ２を中心とした円板３４Ａの外周の全長の約１／４以下に設定されている。）。A support portion 34 is formed at the lower end of the shaft portion 32. That is, the support portion 34 has the disc 34A, and the disc 34A is coaxially connected to the shaft portion 32. A pair of forks 34B, 34B are formed on the peripheral edge of the disk 34A so as to face each other. As a result, the forks 34B and 34B are arranged to face each other along the outer circumference of the disc 34A as shown in FIG. The fork 34B is formed in an arcuate shape along the outer circumference of the disk 34A, and the arcuate circumferential length L 1 is such that a grinding fluid can be supplied to the peripheral edge of the disk 34A other than the fork 34B. 2 (for example, in FIG. 2, the arcuate circumferential length L 1 of the fork 34B is set to be about ¼ or less of the total length of the outer circumference of the disc 34A around the shaft portion 32). ).
【００１３】 また、円板３４Ａの中央にはフォーク３４Ｃが形成されていて、フォーク３４ Ｃはシャフト部３２と同軸上に配設されている。 さらに、一対のフォーク３４Ｂ、３４Ｂ及びフォーク３４Ｃのそれぞれの下端 には、砥石部３６が固着されている。すなわち、砥石部３６は一対の外径砥石３ ６Ａと内径砥石３６Ｂを有していて、一対の外径砥石３６Ａはそれぞれフォーク ３４Ｂ、３４Ｂの下端に固着されている。外径砥石３６Ａは、シャフト部３２を 中心とした円弧Ａ（図２参照）に沿って弓形に形成されている。従って、シャフ ト部３２が回動すると一対の外径砥石３６Ａはシャフト部３２を中心とした円弧 Ａに沿って回動するので、図４に示すようにガラス板１０から円板１０Ａを抜き 出すことができる。Further, a fork 34C is formed at the center of the disc 34A, and the fork 34C is arranged coaxially with the shaft portion 32. Further, a grindstone portion 36 is fixed to the lower end of each of the pair of forks 34B, 34B and 34C. That is, the grindstone portion 36 has a pair of outer diameter grindstones 36A and an inner diameter grindstone 36B, and the pair of outer diameter grindstones 36A are fixed to the lower ends of the forks 34B and 34B, respectively. The outer diameter grindstone 36A is formed in an arc shape along an arc A (see FIG. 2) centering on the shaft portion 32. Therefore, when the shaft portion 32 rotates, the pair of outer diameter grindstones 36A rotate along the arc A around the shaft portion 32, so that the disk 10A is extracted from the glass plate 10 as shown in FIG. be able to.
【００１４】 そして、外径砥石３６Ａの周長Ｌ2 は、一対の外径砥石３６Ａ以外の円弧Ａの 部分が研削液を供給可能なスペースとなるように設定されている（例えば、図２ 上では外径砥石３６Ａの周長Ｌ2 は、シャフト部３２を中心とした円弧Ａの全長 の約１／４以下に設定されている。）。従って、研削時に、研削液は一対の外径 砥石３６Ｂ以外の円弧Ａの部分に供給されるので、研削液は一対の外径砥石３６ Ｂの研削部に供給される。The peripheral length L 2 of the outer diameter grindstone 36A is set so that the portion of the arc A other than the pair of outer diameter grindstones 36A becomes a space capable of supplying the grinding liquid (for example, in FIG. 2). Then, the circumferential length L 2 of the outer diameter grindstone 36A is set to about 1/4 or less of the total length of the arc A centering on the shaft portion 32). Therefore, at the time of grinding, the grinding liquid is supplied to the portion of the arc A other than the pair of outer diameter grindstones 36B, so that the grinding liquid is supplied to the grinding portion of the pair of outer diameter grindstones 36B.
【００１５】 また、外径砥石３６Ａの厚みＴ2 は、フォーク３４Ｂの厚みＴ1 より厚く設定 されている。従って、研削時に、フォーク３４Ｂとガラス板１０の研削部間に隙 間が形成されるので、この隙間に研削液が供給される。これにより、研削液が一 対の外径砥石３６Ｂの研削部に十分に供給される。 内径砥石３６Ｂはフォーク３４Ｃの下端に固着されていて、内径砥石３６Ｂの 先端はテーパ状に形成されている。さらに、内径砥石３６Ｂは断面が略矩形状に 形成されていて、略矩形状の対向する一対の面をシャフト部３２を中心とした円 弧Ｂに沿って湾曲に形成した。従って、内径砥石３６Ｂが回動すると、内径砥石 ３６Ｂの一対の湾曲面で円板１０Ａの中心に開口孔１０Ｂが開口される。そして 、内径砥石３６Ｂの他の一対の平面３６Ｃ、３６Ｃが対向して形成されていて、 研削時には平面３６Ｃ、３６Ｃと円板１０Ａの開口孔１０Ｂ間に研削液が供給さ れる。これにより、研削液は内径砥石３６Ｂの研削部に供給される。Further, the thickness T 2 of the outer diameter grindstone 36A is set to be thicker than the thickness T 1 of the fork 34B. Therefore, at the time of grinding, a gap is formed between the fork 34B and the grinding portion of the glass plate 10, and the grinding liquid is supplied to this gap. As a result, the grinding liquid is sufficiently supplied to the grinding portion of the pair of outer diameter grindstones 36B. The inner diameter grindstone 36B is fixed to the lower end of the fork 34C, and the tip of the inner diameter grindstone 36B is formed in a tapered shape. Further, the inner diameter grindstone 36B is formed to have a substantially rectangular cross section, and a pair of substantially rectangular opposing surfaces are formed to be curved along an arc B centered on the shaft portion 32. Therefore, when the inner diameter grindstone 36B rotates, the opening hole 10B is opened at the center of the disc 10A by the pair of curved surfaces of the inner diameter grindstone 36B. Further, another pair of flat surfaces 36C, 36C of the inner diameter grindstone 36B are formed so as to face each other, and a grinding liquid is supplied between the flat surfaces 36C, 36C and the opening hole 10B of the disc 10A during grinding. As a result, the grinding fluid is supplied to the grinding portion of the inner diameter grindstone 36B.
【００１６】 尚、図１上で４２は研削液を供給するための案内路である。 前記の如く構成された本考案に係る内・外径研削砥石の作用について説明する 。 先ず、研削砥石３０のシャフト部３２を研削装置の回動軸に取り付ける。これ により、シャフト部３２の案内路４２が研削装置の研削液供給源に連通される。 この状態で研削液供給源を駆動すると、案内路４２を介して研削液が外径砥石３ ６Ａ、内径砥石３６Ｂに供給される。Reference numeral 42 in FIG. 1 is a guide path for supplying a grinding fluid. The operation of the inner / outer diameter grinding wheel according to the present invention configured as described above will be described. First, the shaft portion 32 of the grinding wheel 30 is attached to the rotary shaft of the grinding device. As a result, the guide path 42 of the shaft portion 32 is communicated with the grinding fluid supply source of the grinding device. When the grinding fluid supply source is driven in this state, the grinding fluid is supplied to the outer diameter grindstone 36A and the inner diameter grindstone 36B through the guide passage 42.
【００１７】 次に、図１、図２に示すように、研削砥石３０を反時計回り方向に回動して、 一対の外径砥石３６Ａ、３６Ａで密着一体化された複数のガラス板１０、１０… を研削する。この場合、一対の外径砥石３６Ａがシャフト部３２を中心とした円 弧Ａに沿って回動して複数のガラス板１０、１０…から円板１０Ａ、１０Ａ…が 抜き出される。同時に内径砥石３６Ｂは、円板１０Ａ、１０Ａ…の中央に開口孔 １０Ｂを開口する。Next, as shown in FIGS. 1 and 2, the grinding wheel 30 is rotated in the counterclockwise direction, and a plurality of glass plates 10, which are tightly integrated with each other by a pair of outer diameter wheels 36A, 36A, 10 ... is ground. In this case, the pair of outer diameter grindstones 36A rotate along the arc A centering on the shaft portion 32, and the disks 10A, 10A ... Are extracted from the plurality of glass plates 10, 10 ,. At the same time, the inner diameter grindstone 36B opens an opening hole 10B in the center of the discs 10A, 10A.
【００１８】 そして、外径砥石３６Ａ、３６Ａ及び内径砥石３６Ｂで研削される部分が浅い 場合には、研削液が容易に外径砥石３６Ａ、３６Ａ及び内径砥石３６Ｂで研削さ れる部分まで供給される。 さらに、研削が継続されると、外径砥石３６Ａ、３６Ａ及び内径砥石３６Ｂで 研削される部分が深くなる。この場合、案内路４２を介して供給された研削液は 、一対の外径砥石３６Ｂ以外の円弧Ａの部分に供給されるので、研削液は一対の 外径砥石３６Ｂの研削部に供給される。また、内径砥石３６Ｂの平行部３６Ｃ、 ３６Ｃと円板１０Ａの開口孔１０Ｂ間にも研削液が供給されるので、研削液は内 径砥石３６Ｂの研削部に供給される。従って、外径砥石３６Ａ、３６Ａ及び内径 砥石３６Ｂで研削される部分が深くなった場合でも、研削液を研削部分まで供給 することができる。When the portion to be ground by the outer diameter grindstones 36A, 36A and the inner diameter grindstone 36B is shallow, the grinding liquid is easily supplied up to the portion to be ground by the outer diameter grindstones 36A, 36A and the inner diameter grindstone 36B. . Further, if the grinding is continued, the portions to be ground by the outer diameter grindstones 36A, 36A and the inner diameter grindstone 36B become deeper. In this case, since the grinding fluid supplied through the guide path 42 is supplied to the portion of the arc A other than the pair of outer diameter grindstones 36B, the grinding fluid is supplied to the grinding portion of the pair of outer diameter grindstones 36B. . Further, since the grinding liquid is also supplied between the parallel portions 36C and 36C of the inner diameter grindstone 36B and the opening hole 10B of the disc 10A, the grinding liquid is supplied to the grinding portion of the inner diameter grindstone 36B. Therefore, even when the portion to be ground by the outer diameter grindstones 36A, 36A and the inner diameter grindstone 36B becomes deep, the grinding liquid can be supplied to the grinding portion.
【００１９】 前記実施例においては外径砥石３６Ａ、３６Ａ及び内径砥石３６Ｂを一体的に 構成したが、これに限らず、内径砥石３６Ｂを外径砥石３６Ａ、３６Ａから着脱 自在に構成してもよい。すなわち、図３に示すように内径砥石３６Ｂが固定され ているフォーク４４の上端に雄ねじ４４Ａを形成して、雄ねじ４４Ａを円板３４ Ａの中央に着脱自在にねじ結合してもよい。図３に示す実施例によれば外径砥石 ３６Ａ又は内径砥石３６Ｂのいずれか一方の砥石のみが寿命になって、他方の砥 石が使用できる場合に、寿命になった一方の砥石のみを交換することができる。 従って、砥石を無駄なく使用することができる。Although the outer diameter grindstones 36A, 36A and the inner diameter grindstone 36B are integrally formed in the above-described embodiment, the invention is not limited to this, and the inner diameter grindstone 36B may be detachable from the outer diameter grindstones 36A, 36A. . That is, as shown in FIG. 3, a male screw 44A may be formed on the upper end of the fork 44 to which the inner diameter grindstone 36B is fixed, and the male screw 44A may be detachably screwed to the center of the disc 34A. According to the embodiment shown in FIG. 3, when only one of the outer diameter grindstone 36A and the inner diameter grindstone 36B has reached the end of life and the other grindstone can be used, only the one end of life is replaced. can do. Therefore, the grindstone can be used without waste.
【００２０】 前記実施例においては密着一体化された複数のガラス板１０、１０…を研削し て複数の円盤状のガラス板１０Ａ、１０Ａ…を抜き出す場合について説明したが 、これに限らず、その他のワークを研削する場合に使用してもよい。 尚、前記実施例においては加工するワークをガラス板で説明したが、ワークの 材質としてはセラミック、シリコン、ガラス、プラスチック、アルミ、及び木材 等、ほとんどの材質が適用可能である。In the above-described embodiment, a case has been described in which the plurality of glass plates 10, 10 ... Which are closely integrated are ground to extract the plurality of disc-shaped glass plates 10A, 10A ..., but the present invention is not limited to this. It may be used when grinding the workpiece. Although the work to be processed is described as a glass plate in the above embodiment, almost any material such as ceramic, silicon, glass, plastic, aluminum, and wood can be applied to the work.
