<p>機械王の休日、第76回をお送りします。<strong>ハイパワー系工作が目立つPOKA先生ですが、実は刃物研ぎにも一家言があります。</strong>本連載でも、加工用途に使うためのメスの再研磨や、プラ板カッターを研いで再生したことがありました。今回は、そんなPOKA先生がお送りする<strong>「人造砥石の使いこなし」</strong>についてです。</p>

<h2 class="wp-block-heading"><span id="toc1">品質が安定している人造砥石</span></h2>



<p>砥石といっても天然ものから人工的に作られたもの、水を使う水砥石や水の代わりに油を使う油砥石などなど、実に様々な種類があります。</p>



<p><strong>それぞれ特徴があり、使い分ける必要もあるのですが、今回はこの中でも、人造砥石について触れていきましょう。</strong></p>



<p>人造砥石は、人工的に製造された砥石であり、品質が安定しており、安価だという利点があります。天然砥石よりもはるかに硬質なものが製造できるので、極端に硬い刃物を研ぐには必須な砥石です。</p>



<p>では、ホームセンターなどで手軽に入手できる、2種類の砥石をピックアップしてみます。</p>

</div>




<h2 class="wp-block-heading"><span id="toc2">アルミナ砥石</span></h2>



<p><strong>もっとも一般的だと言える砥石が「アルミナ砥石」です。</strong></p>



<a href='https://www.cl20.jp/portal/wp-content/uploads/2019/12/al.jpg'><img fetchpriority="high" decoding="async" width="300" height="225" src="https://www.cl20.jp/portal/wp-content/uploads/2019/12/al-300x225.jpg" class="attachment-thumbnail size-thumbnail" alt="" srcset="https://www.cl20.jp/portal/wp-content/uploads/2019/12/al-300x225.jpg 300w, https://www.cl20.jp/portal/wp-content/uploads/2019/12/al-500x375.jpg 500w, https://www.cl20.jp/portal/wp-content/uploads/2019/12/al-768x575.jpg 768w, https://www.cl20.jp/portal/wp-content/uploads/2019/12/al-800x599.jpg 800w, https://www.cl20.jp/portal/wp-content/uploads/2019/12/al.jpg 1000w" sizes="(max-width: 300px) 100vw, 300px" /></a>



<p>酸化アルミニウム＝アルミナが主成分で、赤茶色っぽい見た目をしている製品が多いようです。実際に見たことがある方も多いのではないでしょうか。</p>



<p>中仕上げから仕上げまで各種揃っていて、包丁を研ぐなど、<strong>家庭向けの用途には手頃</strong>だと言えます。<strong>一方で、硬度の問題で超硬合金の研磨には向きません。</strong></p>

<p>ネット通販で実際に「溶融アルミナ研削材」が使われている砥石を見てみましたが、商品説明に「セラミック包丁には向いていません」と書かれています。この辺はやはり硬度の問題でしょう。</p>

<h2 class="wp-block-heading"><span id="toc3">GC砥石</span></h2>



<p><strong>グリーンカーボランダム＝炭化ケイ素と呼ばれる素材を使った砥石が「GC砥石」です。</strong></p>



<a href='https://www.cl20.jp/portal/wp-content/uploads/2019/12/gc.jpg'><img decoding="async" width="300" height="225" src="https://www.cl20.jp/portal/wp-content/uploads/2019/12/gc-300x225.jpg" class="attachment-thumbnail size-thumbnail" alt="" srcset="https://www.cl20.jp/portal/wp-content/uploads/2019/12/gc-300x225.jpg 300w, https://www.cl20.jp/portal/wp-content/uploads/2019/12/gc-500x375.jpg 500w, https://www.cl20.jp/portal/wp-content/uploads/2019/12/gc-768x575.jpg 768w, https://www.cl20.jp/portal/wp-content/uploads/2019/12/gc-800x599.jpg 800w, https://www.cl20.jp/portal/wp-content/uploads/2019/12/gc.jpg 1000w" sizes="(max-width: 300px) 100vw, 300px" /></a>



<p><strong>こちらはアルミナ砥石とは違ってたいへん硬い研磨成分であり、超硬合金の研磨も可能です。</strong>ただし、破砕性が良いという特徴があり、アルミナ砥石に比べて平面が狂いやすいと言え、頻繁な平面出しが必要になります。荒研ぎ用の砥石が一般的です。</p>

<h2 class="wp-block-heading"><span id="toc4">小型刃物の研磨</span></h2>



<p>せっかく砥石の紹介をしたので、実際に刃物を研いでみましょう。今回はGC砥石で、旋盤のバイトを研いでみます。</p>



<a href='https://www.cl20.jp/portal/wp-content/uploads/2019/12/sokumen.jpg'><img loading="lazy" decoding="async" width="225" height="300" src="https://www.cl20.jp/portal/wp-content/uploads/2019/12/sokumen-225x300.jpg" class="attachment-thumbnail size-thumbnail" alt="" srcset="https://www.cl20.jp/portal/wp-content/uploads/2019/12/sokumen-225x300.jpg 225w, https://www.cl20.jp/portal/wp-content/uploads/2019/12/sokumen-500x668.jpg 500w, https://www.cl20.jp/portal/wp-content/uploads/2019/12/sokumen.jpg 749w" sizes="(max-width: 225px) 100vw, 225px" /></a>



<p><strong>普通の包丁などを研ぐ場合は、幅の広い面を使って研ぐのが普通ですが、こういった小型の刃物を研磨する場合は、砥石の側面で行うのがオススメです。</strong></p>



<p>刃が長いなら面積が広い方が研ぎやすいですが、小型であればそれほどの面積は必要ありません。また、平面出し時にも、面積が小さい方が作業が楽になります。</p>



<p>ちょっとしたことですが、砥石も使い減りするものなので、効率よくいきましょう。</p>



<p><strong>刃物を研ぐのは良いぞ、諸君！</strong></p>

<p>この工具、<strong>実は電子工作などで使うガラスエポキシの板に使うのも、比較的簡単に切断できるので便利</strong>なのですが、一つ問題点があります。</p>



<p>もともとの用途であるアクリルや塩ビの切断のみに使う分にはそうそう切れ味の落ちないプラ板カッターですが、<strong>なにぶんガラスエポキシは硬く、普通の鋼材を使っているプラ板カッターだとすぐに刃先が丸まってしまい、切れなくなってしまうのです。</strong></p>



<p>用途外の使い方をしているため、ある程度は仕方ないでしょう。</p>

<p>しかし、このように替え刃はあるのですが、刃先がなまる度に都度、刃を交換するのは経済的ではありません。</p>



<p><strong>よって、プラ板カッターを自分で研ぎ直して再生し、節約してみましょう。</strong></p>

<h2 class="wp-block-heading"><span id="toc3">油砥石で仕上げる</span></h2>



<p>ルーターで削ったままでは刃先にバリが残っており、好ましい状態とは言えません。<strong>ルーターでの荒削りが終わったら、油砥石を使って仕上げましょう。</strong></p>

<p>油砥石は水砥石と違って、文字通り油を潤滑液として使って研ぐもの。水砥石に比べて油砥石は硬く、簡単に平面が狂わないのも特徴です。</p>



<p>丁寧にバリを取って仕上げてやれば作業は終わりです。慣れてしまえば大した作業ではなく、ちょっとの手間でプラ板カッターの刃は新品同様になります。</p>



<p><strong>刃物を研ぐのは良いぞ、諸君！</strong></p>

<h2><span id="toc1">使い捨てメスを再研磨する</span></h2>
<p>メスというとくられ先生のトレードマークとして大きなメスがあります。しかし、昔ながらのメスは今では珍しく、<strong>衛生的な観点から、医療用のメスはそのほとんどがディスポーザブル・・・つまり、使い捨てです。</strong></p>
<p>

<p>しかし、最近では細かな加工に便利ということで、手芸店やホームセンターに、この使い捨てメスが置いてある事があります。<strong>メスの切れ味は鋭く、加工に使っても大変便利なツールなのです。</strong></p>

<p>ただし、この<strong>医療用メス</strong>は、手術中に骨や歯などに刃先があたっても、<strong>刃こぼれして破片が出ないように比較的柔らかくなるように熱処理されてます。</strong>割れた破片が体内に飛び散ったりしたら大惨事なのでこのようになっている訳ですが、その関係ですぐに切れ味が落ちてしまうのが欠点です。</p>
<p>そこで、今回は切れなくなった使い捨てメスを研ぎ直してやる事にしましょう。医療用途では、昔ならいざ知らず、再研磨して使うのは駄目なのですが、それ以外の用途に使う分には問題ないでしょう。簡単に研ぐ事ができれば、長く使えて経済的です。</p>

<p>水砥石と違い、油を潤滑液として使って研ぎます。<strong>水砥石に比べると、オイルストーンは大変に硬く、簡単には平面が狂いません。</strong>天然のオイルストーンはアーカンサスストーンが有名で、人工の物よりもきめ細かい仕上がりとなります。</p>

<p>まずは表面を研ぎ、反対側にカエリが出てきたら、最後に刃の裏側を数回研げば、研ぎ終わりです。</p>
<p>使い捨てメスの刃先は繊細ながらも、先ほど触れた通り、柔らかく出来ています。このため、すぐに良く切れる刃が付くのが特徴です。<strong>作業時間としては慣れてくれば一分もかかりません。</strong></p>
<p>これだけで新品同様の切れ味に戻ります。ただし、切れ味が落ちるのも早いので、マメに研いでやると良いでしょう。</p>
<p><strong>刃物研ぎは良いぞ、諸君！</strong></p>
