この発明はホーニング盤に用いるホーニング砥石の改良
に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to improvements in honing wheels used in honing machines.
一般のホーニング加工用ホーニング砥石は、ホーニング
盤のヘッドに組込んで、ヘッドの内側より砥石に圧力を
加木ながら被研削物に接触させ、被研削物に対して砥戸
を回転さすながら軸方向に往復動させて研削を行うが、
微小切刃の集合体である砥石が被研削物と密着しながら
回転するため、各微小切刃により切削された切屑や研削
中に脱落した微小切刃の排出性が悪い。A honing stone for general honing processing is installed in the head of a honing machine, and the grinding wheel is brought into contact with the workpiece while applying pressure from the inside of the head, and the honing stone is rotated against the workpiece in the axial direction. Grinding is performed by reciprocating the
Since the grindstone, which is an assembly of micro-cutting blades, rotates while being in close contact with the object to be ground, it is difficult to discharge the chips cut by each micro-cutting blade and the micro-cutting edges that fall off during grinding.
このためこれら切屑や脱落した微小切刃が研削中に砥石
と被研削物の中に咬込まれて、被研削物にスクラッチと
称する掻き傷を生ずる。For this reason, these chips and fallen micro-cutting edges get caught in the grindstone and the object to be ground during grinding, causing scratches on the object to be ground.
特にメタルボンドで焼結したダイヤモンド砥石等を用い
ると上記スクラッチが顕著に生じる欠点がある。In particular, when a diamond grindstone or the like sintered with a metal bond is used, the above-mentioned scratches occur significantly.
この発明はかかる従来のホーニング砥石が有する欠点を
除去する目的でなされたもので、砥石本体の回転方向に
対する前側に、砥石本体のほぼ全長に亘って微小切刃材
を含まぬ接着剤層で形成された無微小切刃層を設けたホ
ーニング砥石を提供することにより、砥石本体の前部に
おける微小切刃材の脱落を防止して、脱落した微小切刃
材の咬み込みによるスクラッチの発生を未然に防止しよ
うとするものである。This invention was made with the aim of eliminating the drawbacks of such conventional honing wheels, and is made by forming an adhesive layer that does not contain microcutting blade material over almost the entire length of the grinding wheel body on the front side in the rotational direction of the grinding wheel body. By providing a honing whetstone with a non-fine cutting edge layer, it is possible to prevent the fine cutting blade material from falling off at the front part of the grinding wheel body, and to prevent the occurrence of scratches due to biting of the fallen fine cutting blade material. The aim is to prevent this from happening.
以下この発明を図示の一実施例について詳述する。The present invention will be described in detail below with reference to an illustrated embodiment.
図において1はホーニング砥石の本体で、砥石ベース2
を介して矢印aの方向に回転される砥石シュウ3に固着
されている。In the figure, 1 is the main body of the honing stone, and the whetstone base 2
The grindstone shoe 3 is fixed to the grindstone shoe 3 which is rotated in the direction of the arrow a.
上記砥石本体1及び砥石シュウ3は図示しないホーニン
グ盤の回転ヘッドに1個ないし複数個取付けられて、矢
印a方向の回転とともに矢印す方向へ往復動されるよう
になっている。One or more of the grindstone main body 1 and the grindstone shoe 3 are attached to a rotating head of a honing machine (not shown) so that they are rotated in the direction of arrow a and reciprocated in the direction indicated by the arrow.
上記砥石本体1は例えばボンドやベークライトまたはエ
ポキシ樹脂などの接着剤によりダイヤモンド粒やボラゾ
ンもしくはAl2O3粒などの微小切刃材4を結合して
形成されていると共に、上記砥石本体1の回転方向aに
対する前部に、上記微小切刃材4を含まない接着剤層の
みよりなる無微小切刃層5が砥石本体1の全長に亘って
設けられている。The grinding wheel body 1 is formed by bonding fine cutting blade materials 4 such as diamond grains, borazone, or Al2O3 grains with an adhesive such as bond, Bakelite, or epoxy resin. A non-fine cutting edge layer 5 made of only an adhesive layer and not containing the microscopic cutting edge material 4 is provided at the front portion over the entire length of the grindstone body 1.
なお上記脱落してもスクラッチを生じない極微小切刃材
であれば第5図に示すように上記無微小切刃層5に混入
しても支障はない。It should be noted that if the extremely fine cutting blade material does not cause scratches even if it falls off, there will be no problem even if it mixes into the fine cutting edge layer 5 as shown in FIG.
また無微小切刃層5の前面を第6図に示すように予め角
度θを付しておけば切屑などの異物との干渉が軽減でき
:る効果も期待できる。Furthermore, if the front surface of the non-fine cutting edge layer 5 is preliminarily inclined at an angle θ as shown in FIG. 6, it can be expected that interference with foreign matter such as chips can be reduced.
しかして研削時砥石本体1゛が受ける切削抵抗に対して
(接着層の接着力)×(微小切刃の表面積〕なる接着強
度が小さい時に、微小切刃材4が砥石本体1より脱落す
る。Therefore, when the adhesive strength (adhesive force of the adhesive layer) x (surface area of the micro-cutting blade) is small with respect to the cutting resistance that the grindstone main body 1 receives during grinding, the micro-cutting blade material 4 falls off from the grindstone main body 1.
この脱落した微小切刃材4が砥石本体1と被研削物6と
の間に咬み込まれると、被研削物6にスクラッチが発生
する原因となるが、特に砥石本体1の回転方向に対する
前部は、微小切刃材4の表面積に対して接着剤の接着強
度がもつとも小さいことから、微小切刃材4の脱落もも
つとも激しい。If this fallen micro-cutting blade material 4 is caught between the grinding wheel body 1 and the object to be ground 6, it will cause scratches on the object to be ground 6, especially at the front part of the grinding wheel body 1 in the rotational direction. Since the adhesive strength of the adhesive is small relative to the surface area of the micro-cutting blade material 4, the micro-cutting blade material 4 may easily fall off.
そこで、この発明では砥石本体1の回転方向に対する前
部に無微小切刃層5を形成した。Therefore, in the present invention, a non-fine cutting edge layer 5 is formed at the front portion of the grindstone body 1 in the rotational direction.
これによって砥石本体1の前部は接着剤層のみとなって
接着力はもつとも強く、従って微小切刃の脱落は全くな
いと共に、この部分の切削もないことから、切屑の咬み
込みによるスクラッチの発生も同時に防止できるように
なる。As a result, the front part of the grinding wheel body 1 is left with only an adhesive layer, and the adhesive force is strong, so there is no chance of the tiny cutting blades falling off, and since there is no cutting in this area, scratches due to biting of chips occur. can be prevented at the same time.
この発明は以上詳述したように、砥石本体の回転方向に
対する前部に、微小切刃材を含まない無微小切刃層を設
けたことから、ホーニング加工時砥石本体の特に前部か
ら脱落した微小切刃や切削された切屑などの咬み込みに
より生じるスクラッチの発生が未然に防止できるように
なる。As described in detail above, this invention provides a non-fine cutting edge layer that does not contain microscopic cutting edge material at the front part of the whetstone body in the rotational direction, so that it does not fall off, especially from the front part of the whetstone body during honing. It becomes possible to prevent the occurrence of scratches caused by biting of small cutting edges and cut chips.
特にスクラッチの発生しやすいメタルボンド砥石に採用
してその効果は顕著であるが、勿論一般のホラシンやA
l2O3系砥石に適用してもその効果はきわめて大きい
。The effect is particularly noticeable when applied to metal bonded whetstones that are prone to scratches, but of course general horacin and A
Even when applied to l2O3 type grindstones, the effect is extremely large.
