The purpose of the present invention is to provide a cutting oil supply method that can prolong the life of the cutting tool without using the cutting tool. In a mirror processing device that processes a mirror surface by cutting, the upper end of the processing surface is heated so that the cutting oil flows downward from the upper end of the processing surface and is applied to the cutting tool in the middle of the flow. The feature is that the droplet is dropped at a position above the part.
本発明は、ポリゴンミラーなどを鏡面加工するための鏡
面加工装置における切削油供給方法に関する。The present invention relates to a cutting oil supply method in a mirror finishing apparatus for mirror finishing a polygon mirror or the like.
レーザビームプリンタに用いられているポリゴンミラー

することによって得られるが、レーザビームプリンタの
普及にともなって、ポリゴンミラーの大量生産及び製造
原価の低減が望まれている。The polygon mirrors used in laser beam printers are obtained by mirror-finishing the surface of light metal using a diamond tool, but as laser beam printers become more widespread, mass production of polygon mirrors and reduction in manufacturing costs are desired. ing.
従来より、ポリゴンミラーの鏡面加工に当たって、以下
に述べる鏡面加工装置が用いられている。2. Description of the Related Art Conventionally, the following mirror polishing apparatus has been used for mirror polishing polygon mirrors.
すなわち、本発明の実施例の鏡面加工装置ｌを示す第１
図及び第２図において、鏡面加工装置ｌは、アルミニウ

固定軸１０で固定支持した状態で、当該加工面１２をバ
イ１−１３で切削するように構成されている。That is, the first example showing the mirror finishing apparatus l according to the embodiment of the present invention
In the figures and FIG.
... are arranged coaxially so that these polygon mirrors 11 overlap each other, and are fixedly supported by the fixed shaft 10 so that the machined surface 12 is vertical, and the machined surface 12 is cut with the bis 1-13. is configured to do so.

台に幼心Ｃ１から半径Ｒ１だけ偏心した位置に取り付け
られている。なお刃部１５は、その幅が３〜４ｍｍであ
り、その内の３分の１程度が加工面１２と接触する。The cutting tool 13 consists of a shank 14 and a blade part 15 made of a single layer of diamond attached to the tip of the shank 14, and the shank 14 is placed on a rotating tool post (not shown) at a position eccentric by a radius R1 from the young center C1. installed. Note that the blade portion 15 has a width of 3 to 4 mm, and about one-third of the width is in contact with the processing surface 12.
この状態で、刃物台が矢印Ｍ１方向へ回転するとともに
矢印Ｍ２方向へ送られると、刃部１５がポリゴンミラー
１１の加工面１２を上から下へ移動しつつ微小量づつ加
工面１２を左から右へ移動し、この間に、加工面１２が
鏡面に仕上げられる。In this state, when the tool rest rotates in the direction of arrow M1 and is also sent in the direction of arrow M2, the blade part 15 moves from top to bottom on the processing surface 12 of the polygon mirror 11 and cuts the processing surface 12 minute by minute from the left. The machine moves to the right, and during this time the machined surface 12 is finished into a mirror surface.
そして、従来においては、切削油の供給方法として、圧
縮空気に切削油を混合してミスト状態とし、これを加工
面１２に吹きつける方法が採用されていた。Conventionally, as a method for supplying cutting oil, a method has been adopted in which the cutting oil is mixed with compressed air to form a mist, and the mist is sprayed onto the processing surface 12.
しかし、上述した従来の切削油供給方法によると、圧縮
空気の吹きつけによって乱気流が発生し、この乱気流に
切粉が巻き込まれてバイトに絡みついて加工面１２を引
っ掻いたり、加工面１２に直接衝突して引っ掻いたりす
るため、加工面１２に多数のスクラッチ（キズ）が発生
するという問題があった。However, according to the conventional cutting oil supply method described above, turbulence is generated by the blowing of compressed air, and chips are caught in this turbulence, get entangled with the cutting tool, and scratch the machined surface 12, or collide directly with the machined surface 12. There is a problem in that a large number of scratches (flaws) are generated on the machined surface 12 because the machined surface 12 is scratched.
加工面１２（すなわち鏡面）にスクラッチが発生すると
、光反射率が低下し又は乱反射が起こるなど、ポリゴン
ミラー１１の性能が低下するため、ポリゴンミラー１１
が不良品となり、歩留りが低下することとなる。If scratches occur on the processed surface 12 (i.e. mirror surface), the performance of the polygon mirror 11 will deteriorate, such as a decrease in light reflectance or diffused reflection.
will be defective and the yield will decrease.
また、切削油をミスト状態で吹きつけるのでは切削油の
供給が充分ではなく、そのため刃部１５の温度が上昇し
、ダイヤモンの炭化や摩耗などによってバイト１３の寿
命の低下を招いていた。Furthermore, spraying cutting oil in the form of a mist does not supply enough cutting oil, which causes the temperature of the blade portion 15 to rise, resulting in a reduction in the life of the cutting tool 13 due to carbonization and abrasion of the diamond.
そのため、これらの要因がポリゴンミラー１１の大量生
産のネックとなり、且つ製造原価を押し上げていた。Therefore, these factors have become a bottleneck in the mass production of the polygon mirror 11 and have increased manufacturing costs.
本発明は、上述の問題に鑑み、鏡面加工装置において、

Mirror processing device l that processes into a mirror surface by cutting with 3.
In this step, the cutting oil SY is dripped at a position above the upper end of the machining surface 12 so that it flows downward from the upper end of the machining surface 12 and hits the cutting tool 13 in the middle of the flow. It is characterized by causing

さらに下方へ流下して落下する。The cutting oil SY dripping from the nozzle 21 is applied to the adjacent upper surface 12a.
, and then flows downward along the adjacent upper surface 12a,
It flows down along the processing surface 12 through the boundary between the adjacent upper surface 12a and the processing surface 12, and hits the blade part 15 on the way down.
It flows further downward and falls.

抵抗を充分に低下させる。According to the above-described embodiment, when mirror-finishing the processed surface 12 of the polygon mirror 11 with the pi) 13, the adjacent upper surface 1
Cutting oil SY dropped onto 2a flows down along the machining surface 12, thereby washing away chips adhering to the machining surface 12, etc., and sufficiently cooling the blade portion 15 to sufficiently reduce cutting resistance. let

価の低減が図られる。Therefore, unlike in the past, turbulence does not occur, so scratches on the machined surface 12 due to entrainment and collision of chips do not occur, and the blade portion 15 is sufficiently cooled and cutting resistance is reduced, so the tool 13 has a long life. This prevents a decrease in This allows mass production of the polygon mirror 11 and reduces manufacturing costs.
また、切削油ＳＹを連続して流した場合には、その切削

に滴下させればよい。Furthermore, if the cutting oil SY is continuously flowed, the mass of the cutting oil SY may cause vibrations in the blade section 15, making it impossible to perform accurate machining. When the oil SY is dripped, the amount of oil applied to the blade part 15 is not large and is intermittent, so problems such as vibrations do not occur.In the above embodiment, the position where the cutting oil SY is dripped is Any position in the vertical direction of the upper surface 12a,
Alternatively, it may be a boundary portion between the adjacent upper surface 12a and the processed surface 12. In other words, the cutting oil SY may be dripped at a position above the upper end of the machining surface 12 so that it flows down from the upper end of the machining surface 12 to the lower end.

The polygon mirror 11 may also be sent. The shape of the polygon mirror 11 may be a regular decagon, a regular dodecagon, or another polygon. It is also possible to process only one polygon mirror 11 without overlapping a plurality of polygon mirrors 11. The present invention can also be applied to mirror finishing of general mirrors other than the polygon mirror 11, such as plane mirrors.
