タカッタの耐久性向上のため、近年では超硬合金の使用
も検討されている。FIG. 1 is a diagram showing an example of a slitter cutter for cutting paper. For example, when cutting wide processed paper to a specified width,
A slitter cutter 1 is rotated at a circumferential speed of 10 to 50 m/min, and the processed paper 3 is cut on the outer periphery of a roller 2 provided with grooves on the outer periphery. Hitherto, high-speed steel has been widely used as a slitter cutter for cutting paper. Furthermore, in order to improve the durability of slitter cutters, the use of cemented carbide has been considered in recent years.
しかしながら、従来の高速度鋼のスリッタカッタでは、
耐摩耗性が不十分で、切断による摩耗のため、スリッタ
カッタの交換の頻度が高かった。However, with conventional high-speed steel slitter cutters,
The slitter cutter had to be replaced frequently due to insufficient wear resistance and wear caused by cutting.
また紙を汚すため、防錆油を塗布できないスリッタカッ
タにおいては、錆の発生が問題となっていた。In addition, rust has been a problem in slitter cutters that cannot be coated with anti-corrosion oil because it stains the paper.
近年、スリッタカッタの耐久性向上のため、超硬合金も
普及しつつあり、高速度鋼に比に、耐久性は向上した。In recent years, cemented carbide has become popular in order to improve the durability of slitter cutters, and their durability has improved compared to high-speed steel.
しかし、超硬合金製スリッタカッタでも、摩耗した際刃

。その上コストは、高速度鋼に比べ著しく高い。However, even with a cemented carbide slitter cutter, when it wears out, the blade surface is severely damaged and the surface roughness decreases, causing a phenomenon in which the paper is pulled. Furthermore, in the case of processed paper impregnated with resin, such as tracing paper, the sharpness was not necessarily sufficient. Moreover, the cost is significantly higher than high speed steel.
本発明は、以上の問題点を解決し、安定した長寿命の切
味のよい紙切断用スリッタカッタの提供を目的とする。The present invention aims to solve the above problems and provide a paper cutting slitter cutter with stable, long life and good sharpness.

あることが判明した。Ceramics No. 2 (comparative example): Carbide JIS K2ON o,
3 (Conventional example): As a wear resistance investigation using a high-speed steel paper cutting test, a paper cutting machine with a rotary cutter was used.
As a result of cutting plain paper (copy paper) with a width of 59IffI+ and a thickness of 140μm 1 million times at 1 time/see, the result was N01
It was found that all No. 001, No. 2, and No. 2 had four times the durability compared to No. 3.
第３図は各種セラミックスと超硬合金を用いて摩耗試験

比べ、良好な仕上面を維持できることがわかった。In the wear test, each sample (12 x 12 x 5) finished in a powder slurry of Al2O with a particle size of 300 microns and a surface roughness of 0.1 μm Rmax was heated at 720a++/s for 5 hours.
The results of measuring the amount of wear (■1) after movement at a relative speed of ee are shown. It was found that the ZrO2-based ceramic of the present invention has excellent wear resistance. In addition, the surface roughness after the wear test was 0 for the present invention.
．． It was found that with a diameter of 2 microns, a better finished surface could be maintained compared to the diameter of 0.7 microns made of cemented carbide.

性の向上を図るものである。Based on the above results, ZrO-based ceramics were selected as the material for the paper cutting slitter cutter, but in the present invention, nitrides, carbides, and carbonitrides of Ti, Zr, Hf, V, and Nb are further added to the cutting edge. By providing a coating layer made of one or more types of materials, sharpness and durability are further improved.

密着性を示すものと考えられる。なお、被覆層の厚みは
あまり大きすぎると靭性が低下し、剥離による摩耗が生
じ易くなるので１０μｍ以下とすると良い。The coating layer has extremely high hardness and exhibits good adhesion to ZrO2 ceramics. This coating layer is formed by various vapor deposition methods, but during vapor deposition, metal vapor is
It is thought that this is because metal oxides are formed by reacting with □, and these are strongly bonded to TiN and T i C, which are vapor deposited substances, so that good adhesion is exhibited. Note that if the thickness of the coating layer is too large, the toughness will decrease and wear due to peeling will easily occur, so it is preferable to set the thickness to 10 μm or less.
次にＺｒＯ２系セラミックスの成分限定理由について述

び使用時の刃先欠損が懸念される。The amount of Y2O contained in ZrO2 is preferably 2 to 5 mol% with respect to ZrO2. If it is less than this, monoclinic crystals will increase, and if it is more than this, cubic crystals will increase, so the proportion of tetragonal crystals required for toughening will decrease. There is a concern that the cutting edge of the slitter cutter for cutting one sheet of paper may become damaged during cutting and use.
さらに耐久性を向上させるためには、硬さの高いＡｌ２
Ｏ３を１０〜５０重量％含有させることが有効である。In order to further improve durability, it is necessary to use Al2 with high hardness.
It is effective to contain O3 in an amount of 10 to 50% by weight.
また、摩耗時の面粗さの低下を抑えるために。Also, to suppress the decrease in surface roughness during wear.
ＺｒＯ，系セラミックスの焼結体粒径は３ミクロン以下
が望ましい。The grain size of the sintered body of the ZrO-based ceramic is preferably 3 microns or less.

た。Next, the inventor focused on the fact that the phenomenon of paper being pulled during paper cutting is caused by the friction between the blade surface of the paper cutting slitter cutter and the paper cross section, and investigated the surface roughness of the blade surface and the cutting resistance. added. As a result, it was found that the above problem does not occur when the blade surface is finished to have a surface roughness of 0.01 to 2 microns. Although it is possible to achieve such surface roughness with cemented carbide and high-speed steel, the surface roughness deteriorates quickly to about 1 to 2 microns due to wear, and the surface roughness does not improve over a long period of time as with ZrO and ceramics. It turned out that it could not be maintained.
また、刃先角度も切味に大きく影響し１０〜３０゜の場

ることが難しい。It was also confirmed that the angle of the cutting edge greatly affects the cutting quality, and that when the angle is 10 to 30 degrees, the phenomenon of pulling a piece of paper or problems with the cut surface does not occur. Although it is possible to achieve such a cutting edge angle in the case of high-speed steel or cemented carbide, it is difficult to maintain such an optimum cutting edge angle for a long period of time due to the aforementioned wear phenomenon.
ＺｒＯ，系セラミックスに本発明のように硬質の被覆層
を設けたものは、摩耗面の損傷が穏やかで最適な刃先角
度及び面粗さを長時間維持できる。When a ZrO ceramic is provided with a hard coating layer as in the present invention, damage to the worn surface is mild and the optimal cutting edge angle and surface roughness can be maintained for a long time.
以下、本発明を実施例に基づき説明する。 Hereinafter, the present invention will be explained based on examples.

引っ張る現象が生じ、３５０ｋｍの切断寿命であった。As a result, the slitter cutter D reached the end of its lifespan due to wear after cutting 85 km. In addition, in the case of slitter cutter C, a phenomenon in which the paper was pulled due to friction on the blade surface occurred after 200 km of cutting, and the cutting life was 350 km.
スリッタカッタＡおよびＢの場合、切断寿命はそれぞれ
４２０ｂ、５１０−であり、両者ともに寿命に至るまで
スムーズな切断が行なえた。In the case of slitter cutters A and B, the cutting lives were 420 b and 510 -, respectively, and both could cut smoothly until the end of their lives.

I was able to cut the paper smoothly without pulling it. Note that the roughness of the blade surface of each slitter cutter before the cutting test was 0.2 μm.
