Description
【0001】
【発明の属する技術分野】
本発明は、工具ホルダー保持具(例えば、収納具や把持具)に関する。特に、マシニングセンタ等の工具マガジン装置において、工具交換アーム装置が介在する工具マガジン装置に装備された工具ホルダーを収納する収納具や、工具交換アーム装置が介在しない工具マガジン装置に装備された工具ホルダーのフランジ部を把持するグリップ等の把持具に関する。
【0002】
【発明が解決しようとする課題】
図1に示す如く、工具交換アーム装置が介在する工具マガジン装置に装備された工具ホルダー3を収納するツールポット(フドー株式会社の登録商標)等の工具ホルダー3の収納具1とか、図2及び図3に示す如く、工具交換アーム装置が介在しない工具マガジン装置に装備された工具ホルダー3のフランジ部4を把持するグリップ等の工具ホルダー3の把持具2は、従来、フェノール樹脂などで成形されていた。
【0003】
一般的に、フェノール樹脂は、自己潤滑性があり、摺動性、耐水性、耐久性、耐油性に優れている。
【0004】
しかし、フェノール樹脂のみで、収納具や把持具(以下、工具ホルダー保持具と言う場合もある)を構成した場合、柔軟性に欠けることから、本願出願人によって綿布などの天然繊維を用いることが提案されるに至った。
【0005】
すなわち、フェノール樹脂に綿布を含有させた綿布強化フェノール樹脂成形材料で成形された工具ホルダー保持具は、工具ホルダーの損傷を防止する適度の柔軟性と機械的強度を有していた。
【0006】
尚、上記綿布強化フェノール樹脂成形材料は、フェノール樹脂に綿布と所定の添加剤とメタノール等の溶剤とを加えて混合し、この混合物を所定の温度で乾燥することにより得ていたものである。
【0007】
ところで、このような綿布強化フェノール樹脂成形材料で構成された工具ホルダー保持具は、時間の経過に伴って寸法精度に狂いの生じて来ることが見出されるに至った。
【0008】
すなわち、マシニングセンター等の工作機械において、切削加工を行う場合、切削油として、従来では、油性のものが使用されていたが、近年では、水溶性切削油剤を水で希釈した水溶性切削油が使用され出した。従って、水溶性切削油中の水分が工具ホルダーを通じて工具ホルダー保持具に付着するようになる。ところで、工具ホルダー保持具における綿布の表面は、本来、フェノール樹脂で覆われており、水分の浸透(吸湿)が妨げられているものの、従来の綿布強化フェノール樹脂成形材料で成形された工具ホルダー保持具の内部構造は、綿布が配向性を持ち、互いに重なり合って積層構造をしており、この積層状に重なり合った断層から付着した水分が浸透し易く、この浸透により寸法変化が生じることが判って来た。
【0009】
従って、本発明が解決しようとする課題は、加工に際して水溶性切削油が用いられる工具ホルダーの保持具(収納具や把持具)として適度な柔軟性を有しながらも、機械的強度に優れ、かつ、耐吸湿性があって、寸法安定性に優れた工具ホルダー保持具を提供することである。
【0010】
【課題を解決するための手段】
上記の問題点、即ち、寸法変化の問題を解決するだけであれば、一つには、綿布を含有させないことが考えられる。しかし、これでは、柔軟性がなくなることから、採用できない。
【0011】
尚、本願出願人は、先に、工具ホルダー把持具を帆布、綿布、炭素繊維で強化された熱硬化性樹脂、特に炭素繊維強化フェノール系樹脂で構成することを提案(特願平2−38584)していた。
【0012】
但し、この提案では、綿布と炭素繊維とを併用することは示されていない。又、併用することが好ましいことを示唆する記載もない。すなわち、この提案の技術では、加工に際して水溶性切削油が用いられる工具ホルダーの保持具を対象としていなかった為、吸湿による寸法変化の問題が考えられもしていなかったからである。つまり、水溶性切削油が用いられた場合において、かつ、綿布などの天然繊維を含む素材で工具ホルダー把持具が構成されている場合に、始めて、寸法変化の問題が認識されるようになったからである。逆に、言うと、綿布などの天然繊維を含む素材で工具ホルダー把持具が構成されていても、加工に際して水溶性切削油が用いられない場合には、寸法変化の問題は起きない。又、加工に際して水溶性切削油が用いられる場合でも、炭素繊維を含むものの、綿布などの天然繊維を含まないフェノール系樹脂で構成したに過ぎない場合には、これ、また、寸法変化の問題は起きない。
【0013】
そして、本願発明者による試行錯誤しながらの検討が進められて行った結果、天然繊維と炭素繊維および/またはガラス繊維とを組み合わせた場合、前記水溶性切削油が用いられ、かつ、綿布などの天然繊維を含む場合において起きた寸法変化を大幅に改善できることに気付いたのである。
【0014】
上記知見を基にして本願発明が達成されたものであり、前記の課題は、
水溶性切削油が使用される加工に際して用いられる工具ホルダーの保持具を構成する材料であって、
熱硬化性樹脂と、
天然繊維と、
ガラス繊維および/または炭素繊維
とを含むことを特徴とする工具ホルダー保持具構成材料によって解決される。
【0015】
又、水溶性切削油が使用される加工に際して用いられる工具ホルダーの保持具であって、
上記の工具ホルダー保持具構成材料を用いて構成されてなる
ことを特徴とする工具ホルダー保持具によって解決される。
【0016】
本発明において、天然繊維は、モノフィラメントのような線状のものではなく、モノフィラメントの集合体である布状物や糸状物の形態を有するものであることが好ましい。特に、布状物は好ましいものである。このような形態のものにあっては、単なるモノフィラメントを含有する場合よりも、吸水性が高く、寸法変化の度合いが高い。しかしながら、天然繊維を含有させる大きな目的、即ち、柔軟性および損傷時に破片が周囲に飛び散り難い特性を考慮すると、布状物や糸状物、特に、布状物が好ましい。
【0017】
天然繊維は、天然繊維のみであっても良い。但し、化学繊維と天然繊維とが共に用いられたものを排除するものではない。例えば、合成繊維、人造繊維、再生繊維の布状物や糸状物、更には繊維(モノフィラメント)そのものが天然繊維と共に用いられても差し支えない。但し、化学繊維は、天然繊維に比べて、耐吸湿性は優るものの、柔軟性や熱硬化性樹脂の浸透性が劣る為、化学繊維を用いる場合でも、天然繊維に対して10重量%以下の割合であるのが好ましい。
【0018】
本発明で用いられる天然繊維としては種々のものを使用できる。例えば、綿等の種子毛繊維、麻等の葉繊維、三椏、楮等の植物繊維や、羊毛等の動物繊維が挙げられる。その形態として、上述した通り、上記繊維を原料とする織布や不織布(この種の布の裁断布)、上記繊維を撚った糸(この糸を裁断した裁断糸)を用いることが出来る。
【0019】
天然繊維の大きさは、本発明の目的からすると、繊維が布状物である場合には1×1〜30×30mm程度、繊維が糸状物である場合には1〜20mm程度である。このような大きさのものとしておくことによって、ガラス繊維や炭素繊維の付着性、及び熱硬化性樹脂の浸透性に適していて、耐吸湿性、寸法安定性、機械的強度、柔軟性の特長が最大限に発揮される。
【0020】
本発明では、熱硬化性樹脂および天然繊維だけでなく、更に、ガラス繊維および/または炭素繊維が用いられる。尚、単なる強化用の繊維と言うのみであれば、金属繊維、或いはアラミド繊維なども知られているが、本願発明が対象とする水溶性切削油が使用される加工に際して用いられる工具ホルダー保持具にあっては、天然繊維との相性上から、ガラス繊維および/または炭素繊維を用いる必要が有る。
【0021】
ガラス繊維および/または炭素繊維は、その長さが1〜20mm程度のものが好ましい。繊維のフィラメント径は、例えば5〜20μmである。このような長さのものは、熱硬化性樹脂の浸透性が向上し、又、ガラス繊維および/または炭素繊維が天然繊維の裁断布に均一に付着した様態で絡み合うものとなり、天然繊維の柔軟性を損なわず、耐吸湿性、寸法安定性、機械的強度、柔軟性の特長が最大限に発揮される。
【0022】
熱硬化性樹脂と天然繊維とガラス繊維および/または炭素繊維との配合割合は、熱硬化性樹脂100重量部に対して、天然繊維が19〜200重量部(特に、20重量部以上。150重量部以下。)、ガラス繊維および/または炭素繊維は6〜200重量部(特に、6重量部以上。100重量部以下。)、前記天然繊維とガラス繊維および/または炭素繊維との総量が25〜240重量部であるのが好ましい。更には、熱硬化性樹脂100重量部の割合において、50重量部>(天然繊維の総量)−(ガラス繊維及び炭素繊維の総量)>10重量部であるのが好ましい。このような配合割合のものとすることによって、ガラス繊維・炭素繊維を天然繊維に均一に拡散・付着させるのに適しており、又、天然繊維の柔軟性が十分に確保され、更には繊維全体に熱硬化性樹脂が浸透し、水溶性切削油は浸透し難く、耐吸湿性に優れ、かつ、寸法安定性、機械的強度に優れ、しかも適度の柔軟性が確保されるものとなる。
【0023】
【発明の実施の形態】
本発明になる工具ホルダー保持具構成材料は、水溶性切削油が使用される加工に際して用いられる工具ホルダーの保持具を構成する材料であって、熱硬化性樹脂と、天然繊維と、ガラス繊維および/または炭素繊維とを含む。特に、水溶性切削油が使用される加工に際して用いられる工具ホルダーの保持具を構成する材料であって、熱硬化性樹脂と、天然繊維と、ガラス繊維および/または炭素繊維とを含み、熱硬化性樹脂100重量部に対して、天然繊維が19〜200重量部(特に、20重量部以上。150重量部以下。)、ガラス繊維および/または炭素繊維は6〜200重量部(特に、6重量部以上。100重量部以下。)、前記天然繊維とガラス繊維および/または炭素繊維との総量が25〜240重量部である。又、熱硬化性樹脂100重量部の割合において、50重量部>(天然繊維の総量)−(ガラス繊維及び炭素繊維の総量)>10重量部である。
【0024】
天然繊維は、布状物および/または糸状物の形態のものである。中でも、布状物である。天然繊維は、天然繊維のみの場合、又、化学繊維を含む場合もある。例えば、合成繊維、人造繊維、再生繊維の布状物や糸状物、更には繊維(モノフィラメント)そのものが天然繊維と共に用いられても差し支えない。但し、化学繊維は、耐吸湿性、柔軟性、機械的強度のバランスから鑑みて、天然繊維に対して10重量%以下の割合である。天然繊維としては種々のものがある。例えば、綿等の種子毛繊維、麻等の葉繊維、三椏、楮等の植物繊維や、羊毛等の動物繊維が挙げられる。その形態としては、上述した通り、上記繊維を原料とする織布や不織布(この種の布の裁断布)、上記繊維を撚った糸(この糸を裁断した裁断糸)である。
【0025】
天然繊維の大きさは、布状物のものである場合には1×1〜30×30mm程度、糸状物である場合には1〜20mm程度である。
【0026】
ガラス繊維や炭素繊維は、その長さが、特に、0.5〜20mm、更には1〜10mm程度のものである。炭素繊維としては、ピッチ系あるいはPAN系いずれのものであっても良い。但し、PAN系炭素繊維を用いた場合には、耐吸湿性や機械的強度がより優れており、ピッチ系炭素繊維を用いた場合には、耐吸湿性や摺動性がより優れている。
【0027】
本発明で用いられる熱硬化性樹脂としては、フェノール系樹脂、メラミン系樹脂、エポキシ系樹脂、ポリエステル系樹脂、ジアリルフタレート系樹脂等の熱硬化性樹脂を単独または二種以上を併用して使用できる。これら熱硬化性樹脂は、前述の繊維に対して浸透性が優れ、天然繊維の柔軟性を損なわない。中でも、フェノール系樹脂は、耐水性と前述の繊維に対して浸透性が最も優れており、工具ホルダーの収納具や把持具を構成する熱硬化性樹脂として好ましい。
【0028】
上記成分の他に、例えばアラミド繊維、シリカ繊維などの繊維状物質、炭酸カルシュウム、タルク、クレー、シリカ、グラファイトなどの無機系充填材を用いる場合もある。
【0029】
上記特徴の組成物を用いて本発明になる工具ホルダー保持具構成材料が得られる。すなわち、所定の熱硬化性樹脂に、大きさが1×1〜30×30mmに裁断された天然繊維の織布・不織布の裁断布と、長さ0.5〜20mmに裁断されたガラス繊維・炭素繊維と、所定の添加剤と、メタノール等の溶剤を加えて混合し、熱硬化性樹脂に天然繊維、ガラス繊維・炭素繊維が主成分として含有された混合物を得る。この混合物を所定の温度で乾燥することにより、本発明になる工具ホルダー保持具構成材料が得られる。この混合物を混合する過程において、ガラス繊維・炭素繊維の裁断繊維と天然繊維の裁断布とは均一に分散させられる。
【0030】
本発明になる工具ホルダー保持具(収納具や把持具)は、上記の工具ホルダー保持具構成材料を用いて構成されてなる。すなわち、上記材料を用いて、工具ホルダーの収納具や把持具に圧縮成形または射出成形もしくはトランスファー成形で成形する。尚、この場合、補強材として金属性の部材がインサート成形によって一体形成しても良い。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a tool holder holder (for example, a storage tool or a gripping tool). In particular, in a tool magazine device such as a machining center, a tool for storing a tool holder provided in a tool magazine device in which a tool changing arm device is interposed or a tool holder provided in a tool magazine device in which a tool changing arm device is not interposed. The present invention relates to a gripper such as a grip for gripping a flange portion.
[0002]
[Problems to be solved by the invention]
As shown in FIG. 1, a
[0003]
Generally, phenolic resins have self-lubricating properties and are excellent in sliding properties, water resistance, durability, and oil resistance.
[0004]
However, when a storage tool or a gripping tool (hereinafter, also referred to as a tool holder holding tool) is composed of only phenol resin, the applicant lacks flexibility. It has been proposed.
[0005]
That is, the tool holder holder molded from the cotton cloth reinforced phenol resin molding material in which the phenol resin contains the cotton cloth has appropriate flexibility and mechanical strength for preventing damage to the tool holder.
[0006]
The above-mentioned cotton cloth-reinforced phenolic resin molding material is obtained by adding a cotton cloth, a predetermined additive, and a solvent such as methanol to a phenol resin, mixing and drying the mixture at a predetermined temperature.
[0007]
By the way, it has been found that the dimensional accuracy of the tool holder holder made of such a cotton cloth reinforced phenolic resin molding material is changed with time.
[0008]
That is, when performing cutting in a machine tool such as a machining center, an oil-based cutting oil has been used as a cutting oil, but in recent years, a water-soluble cutting oil obtained by diluting a water-soluble cutting oil with water has been used. I started. Therefore, the water in the water-soluble cutting oil adheres to the tool holder holder through the tool holder. By the way, the surface of the cotton cloth in the tool holder holder is originally covered with a phenol resin, and although penetration of moisture (moisture absorption) is hindered, the tool holder holding the conventional cotton cloth reinforced phenol resin molding material is prevented. The internal structure of the tool has a layered structure in which cotton cloth has orientation and overlaps with each other, and it is understood that moisture attached from the layered faults easily penetrates, and dimensional change is caused by this permeation. Came.
[0009]
Accordingly, the problem to be solved by the present invention is that while having moderate flexibility as a tool holder (storage tool or gripping tool) of a tool holder in which a water-soluble cutting oil is used during processing, it has excellent mechanical strength, Further, it is an object of the present invention to provide a tool holder holder having moisture absorption resistance and excellent dimensional stability.
[0010]
[Means for Solving the Problems]
In order to solve the above problem, that is, the problem of dimensional change only, it is conceivable that one of the problems is not to include a cotton cloth. However, this cannot be adopted because of the lack of flexibility.
[0011]
Incidentally, the applicant of the present application has previously proposed that the tool holder gripper be made of canvas, cotton cloth, or a thermosetting resin reinforced with carbon fiber, particularly a phenolic resin reinforced with carbon fiber (Japanese Patent Application No. 2-38584). )Was.
[0012]
However, this proposal does not show that a cotton fabric and a carbon fiber are used in combination. Further, there is no description suggesting that it is preferable to use them in combination. That is, this proposed technique does not target a holder of a tool holder in which a water-soluble cutting oil is used at the time of processing, and therefore, does not consider a problem of dimensional change due to moisture absorption. In other words, when water-soluble cutting oil is used, and when the tool holder gripper is made of a material containing natural fibers such as cotton cloth, for the first time, the problem of dimensional change came to be recognized. It is. Conversely, if the tool holder gripping tool is made of a material containing natural fibers such as cotton cloth, the problem of dimensional change does not occur if a water-soluble cutting oil is not used for processing. In addition, even when a water-soluble cutting oil is used for processing, if it is composed of a phenolic resin containing carbon fibers but not containing natural fibers such as cotton cloth, this and the problem of dimensional change are also problematic. Does not wake up.
[0013]
As a result of a study conducted by trial and error by the inventor of the present application, when the natural fiber and the carbon fiber and / or the glass fiber are combined, the water-soluble cutting oil is used, and a cotton cloth or the like is used. He realized that the dimensional changes that occurred when natural fibers were included could be significantly improved.
[0014]
The present invention has been achieved based on the above findings,
A material that constitutes a tool holder of a tool holder used in processing in which a water-soluble cutting oil is used,
A thermosetting resin,
With natural fibers,
The problem is solved by a tool holder holder constituent material characterized by including glass fibers and / or carbon fibers.
[0015]
Further, a tool holder holding tool used in processing using a water-soluble cutting oil,
The problem is solved by a tool holder holder characterized by being configured using the above-mentioned tool holder holder constituent material.
[0016]
In the present invention, it is preferable that the natural fiber is not a linear fiber such as a monofilament, but has a form of a cloth or thread which is an aggregate of monofilaments. In particular, a cloth is preferable. In such a form, the water absorption is higher and the degree of dimensional change is higher than in the case of simply containing a monofilament. However, in view of the large purpose of containing natural fibers, that is, the flexibility and the property that fragments are not easily scattered around when damaged, cloths and yarns, particularly cloths are preferable.
[0017]
Natural fibers may be only natural fibers. However, this does not preclude the use of both chemical fibers and natural fibers. For example, synthetic fibers, man-made fibers, regenerated fibers such as cloths and threads, and fibers (monofilaments) themselves can be used together with natural fibers. However, although the chemical fiber has better moisture absorption resistance than the natural fiber, the flexibility and the permeability of the thermosetting resin are inferior. Therefore, even when the chemical fiber is used, 10% by weight or less based on the natural fiber. It is preferably a ratio.
[0018]
Various fibers can be used as the natural fiber used in the present invention. For example, seed fibers such as cotton, leaf fibers such as hemp, plant fibers such as mitsumata and kozo, and animal fibers such as wool are exemplified. As described above, as described above, a woven or non-woven fabric (cutting cloth of this kind) using the fiber as a raw material, or a yarn twisted with the fiber (cutting yarn obtained by cutting this yarn) can be used.
[0019]
For the purpose of the present invention, the size of the natural fiber is about 1 × 1 to 30 × 30 mm when the fiber is a cloth, and about 1 to 20 mm when the fiber is a thread. By keeping it of such a size, it is suitable for adhesion of glass fiber and carbon fiber, and permeability of thermosetting resin, and features of moisture absorption resistance, dimensional stability, mechanical strength, flexibility Is maximized.
[0020]
In the present invention, not only thermosetting resins and natural fibers, but also glass fibers and / or carbon fibers are used. In addition, metal fibers or aramid fibers are also known as long as they are merely reinforced fibers, but a tool holder holder used in processing using a water-soluble cutting oil, which is the object of the present invention. In this case, it is necessary to use glass fibers and / or carbon fibers in view of compatibility with natural fibers.
[0021]
The glass fiber and / or carbon fiber preferably has a length of about 1 to 20 mm. The filament diameter of the fiber is, for example, 5 to 20 μm. With such a length, the permeability of the thermosetting resin is improved, and the glass fiber and / or the carbon fiber are entangled in such a manner that the glass fiber and / or the carbon fiber are uniformly attached to the cut cloth of the natural fiber. The characteristics of moisture absorption, dimensional stability, mechanical strength and flexibility are maximized without impairing the properties.
[0022]
The mixing ratio of the thermosetting resin, the natural fiber, the glass fiber and / or the carbon fiber is such that the natural fiber is 19 to 200 parts by weight (particularly, 20 parts by weight or more; 150 parts by weight, based on 100 parts by weight of the thermosetting resin). Parts by weight), glass fibers and / or carbon fibers are 6 to 200 parts by weight (particularly, 6 parts by weight or more, 100 parts by weight or less), and the total amount of the natural fibers and the glass fibers and / or carbon fibers is 25 to 200 parts by weight. Preferably it is 240 parts by weight. Furthermore, it is preferable that 50 parts by weight> (total amount of natural fibers)-(total amount of glass fibers and carbon fibers)> 10 parts by weight based on 100 parts by weight of the thermosetting resin. By adopting such a mixing ratio, it is suitable for uniformly diffusing and adhering the glass fiber and the carbon fiber to the natural fiber. In addition, the flexibility of the natural fiber is sufficiently ensured. The thermosetting resin penetrates into the resin, the water-soluble cutting oil hardly penetrates, is excellent in moisture absorption resistance, is excellent in dimensional stability and mechanical strength, and has appropriate flexibility.
[0023]
BEST MODE FOR CARRYING OUT THE INVENTION
The tool holder holding material constituting material according to the present invention is a material for forming a tool holder holding tool used in processing in which a water-soluble cutting oil is used, and includes a thermosetting resin, a natural fiber, a glass fiber and And / or carbon fiber. Particularly, it is a material constituting a holder of a tool holder used in processing using a water-soluble cutting oil, the thermosetting resin containing a thermosetting resin, a natural fiber, a glass fiber and / or a carbon fiber, and 19 to 200 parts by weight (particularly, 20 parts by weight or more, 150 parts by weight or less) of natural fiber and 6 to 200 parts by weight (particularly, 6 parts by weight) of glass fiber and / or carbon fiber with respect to 100 parts by weight of the conductive resin. Parts or more and 100 parts by weight or less), and the total amount of the natural fibers and glass fibers and / or carbon fibers is 25 to 240 parts by weight. Further, in the ratio of 100 parts by weight of the thermosetting resin, 50 parts by weight> (total amount of natural fibers) − (total amount of glass fibers and carbon fibers)> 10 parts by weight.
[0024]
Natural fibers are in the form of cloth and / or thread. Among them, it is a cloth. Natural fibers may include only natural fibers or may include chemical fibers. For example, synthetic fibers, man-made fibers, regenerated fibers such as cloths and threads, and fibers (monofilaments) themselves can be used together with natural fibers. However, the content of the chemical fiber is 10% by weight or less based on the natural fiber in view of the balance among moisture absorption resistance, flexibility, and mechanical strength. There are various natural fibers. For example, seed fibers such as cotton, leaf fibers such as hemp, plant fibers such as mitsumata and kozo, and animal fibers such as wool are exemplified. As described above, the form is a woven or non-woven fabric (cutting cloth of this kind) using the above-mentioned fiber as a raw material, or a yarn twisted with the above-mentioned fiber (cutting yarn obtained by cutting this yarn).
[0025]
The size of the natural fiber is about 1 × 1 to 30 × 30 mm in the case of a cloth, and about 1 to 20 mm in the case of a thread.
[0026]
The glass fiber or the carbon fiber has a length of about 0.5 to 20 mm, more preferably about 1 to 10 mm. The carbon fiber may be either pitch-based or PAN-based. However, when the PAN-based carbon fiber is used, the moisture absorption resistance and the mechanical strength are more excellent, and when the pitch-based carbon fiber is used, the moisture absorption resistance and the sliding property are more excellent.
[0027]
As the thermosetting resin used in the present invention, a phenol resin, a melamine resin, an epoxy resin, a polyester resin, a thermosetting resin such as diallyl phthalate resin can be used alone or in combination of two or more. . These thermosetting resins have excellent permeability to the aforementioned fibers and do not impair the flexibility of natural fibers. Among them, a phenolic resin has the highest water resistance and the highest permeability to the above-mentioned fibers, and is preferable as a thermosetting resin constituting a storage tool or a holding tool of a tool holder.
[0028]
In addition to the above components, for example, fibrous substances such as aramid fibers and silica fibers, and inorganic fillers such as calcium carbonate, talc, clay, silica, and graphite may be used.
[0029]
The constituent material of the tool holder holder according to the present invention can be obtained by using the composition having the above characteristics. That is, a predetermined thermosetting resin, a woven or nonwoven cloth of natural fibers cut to a size of 1 × 1 to 30 × 30 mm, and a glass fiber cut to a length of 0.5 to 20 mm. A carbon fiber, a predetermined additive, and a solvent such as methanol are added and mixed to obtain a mixture in which a thermosetting resin contains natural fibers, glass fibers, and carbon fibers as main components. By drying this mixture at a predetermined temperature, the material for forming a tool holder holder according to the present invention can be obtained. In the process of mixing this mixture, the cut fibers of glass fibers and carbon fibers and the cut fibers of natural fibers are uniformly dispersed.
[0030]
The tool holder holder (storage tool or gripper) according to the present invention is configured using the above-described tool holder holder constituent material. That is, compression molding, injection molding, or transfer molding is performed using the above-described material on a storage tool or a gripping tool of a tool holder. In this case, a metallic member may be integrally formed as a reinforcing material by insert molding.

As can be seen from Table 1, the material according to the present invention contains natural fibers and glass fibers and / or carbon fibers, and therefore has little dimensional change and high strength.
[0065]
That is, as compared with those of Comparative Examples 1 and 2 containing natural fibers, those of the present invention have a dimensional change rate reduced to 1/3 to 1/5. And the bending strength is increased 1.7 to 2 times.
[0066]
Further, even when glass fibers or carbon fibers are contained, the amount thereof is small, and when natural fibers are not contained, suppression of dimensional change cannot be improved as in the present invention. And, if the content of glass fiber or carbon fiber is increased, dimensional change can be suppressed, but since it does not contain natural fibers, the flexural modulus becomes too large, lacks flexibility, and fragments are damaged when damaged. There is a high risk of splattering around.
[0067]
In addition, even when natural fibers are used to maintain flexibility, metal fibers are used to suppress the dimensional change caused by including natural fibers. As can be seen from FIG. 10, there is an extremely high risk that the flexural modulus is too large, lacks flexibility, and fragments are scattered around when damaged. Also, in this case, since water-soluble cutting oil is used, rust may be generated. In addition, there is a disadvantage that the weight increases.
[0068]
When Examples 1 to 6 and Example 8 were compared, the ratio of glass fiber or carbon fiber to natural fiber increased, and the ratio of 100 parts by weight of thermosetting resin (total amount of natural fiber) If the condition of-)-(total amount of glass fiber and carbon fiber)> 10 parts by weight is not satisfied, the flexural modulus increases and the function of flexibility starts to decrease. In addition, when Examples 1 to 6 and Example 7 are compared, the ratio of glass fiber or carbon fiber to natural fiber is reduced, and 50 parts by weight> (100 parts by weight of thermosetting resin> It is understood that when the condition of (total amount of natural fibers)-(total amount of glass fibers and carbon fibers) is not satisfied, the dimensional change suppressing function starts to decrease.
[0069]
【The invention's effect】
As a tool holder holder that uses a water-soluble cutting oil during processing, it has excellent mechanical strength, moisture absorption resistance, and excellent dimensional stability, while having appropriate flexibility.
