<h2 class="wp-block-heading"><span id="toc1">旋盤の刃先・切削バイト</span></h2>



<p>旋盤は丸物を加工できる便利な機械です。必要に応じて刃先である切削バイトを取り替えて金属加工をするわけですが、その種類は様々。</p>



<p>それぞれに、長所短所というものがあります。</p>



<p>今回は、この切削バイトの材質や得意とする加工方法、そして今メジャーなものはなんなのかをご紹介しましょう。</p>

<h2 class="wp-block-heading"><span id="toc2">ハイスバイト</span></h2>



<p>まずはハイスバイトから。</p>

<a href='https://www.cl20.jp/portal/wp-content/uploads/2019/11/hasaki.jpg'><img decoding="async" width="225" height="300" src="https://www.cl20.jp/portal/wp-content/uploads/2019/11/hasaki-225x300.jpg" class="attachment-thumbnail size-thumbnail" alt="" srcset="https://www.cl20.jp/portal/wp-content/uploads/2019/11/hasaki-225x300.jpg 225w, https://www.cl20.jp/portal/wp-content/uploads/2019/11/hasaki-500x668.jpg 500w, https://www.cl20.jp/portal/wp-content/uploads/2019/11/hasaki.jpg 749w" sizes="(max-width: 225px) 100vw, 225px" /></a>



<p>全体と刃先のアップはこんな感じです。</p>



<p><strong>ハイスとは「ハイスピードスチール」の略であり、鉄などの金属を加工するのに特化した工具鋼です。</strong></p>



<p>この工具鋼は、旋盤のバイト以外には、ドリルなどに使われています。<strong>超硬などのバイトに比べると粘りが強いのが特徴で、カミソリのように刃先を仕上げられるのが利点です。</strong>自分で削って整形できるため、<strong>規格品のバイトでは加工不可能な場面で威力を発揮します。</strong></p>



<p>一方で欠点もあり、熱に弱いため、高速加工には向きません。また、ハイスバイトは粘り強い反面、硬度の面でも劣るため、焼き入れされた物の加工は難しいです。</p>



<p>このハイスバイトは、近年ではスローアウェイバイトにほとんどが置き換えられたため、中古の工具屋で数百円と大変安価に購入できます。</p>

<p>現在はスローアウェイバイトと呼ばれる物が一般的になっています。使い方としては、刃先が損傷したら交換するといった形で、研いで再利用といったことは基本的にはしません。</p>

<p><strong>このバイトは生産性の高い自動機での高速加工を前提としており、熱に強い特性があります。また、「超硬」なので極めて硬い刃物であり、焼き入れされた素材も加工可能なのが利点です。</strong></p>



<p>欠点としては、かつては切れ味があまり良くないと言われていました。しかし、近年では切れ味の良い交換チップも売られており、ほぼすべての作業はスローアウェイバイトで足りてしまいます。この辺が、ハイスバイトからスローアウェイバイトに置き換えが進んだ理由だと言えるでしょう。</p>



<p>まあ、そうは言っても、加工するものの特性や仕上げたい形状によってモノを使い分けることそのものは変わりません。</p>



<p><strong>旋盤加工はいいぞ、諸君！</strong></p>

<h2><span id="toc1">ホームセンターで大型丸座金を調達する</span></h2>
<p><strong>大型のホームセンターに行けば、様々な金属素材が見つかります。</strong></p>
<p>用途と材質を考えてやる必要はありますが、今回は、<strong>ファイヤーキャノンの接続部品用に、大型の丸座金を採用</strong>しました。咄嗟に大きめの鉄素材が欲しくなった時に、これがなかなか便利なのです。</p>
<p>
<a href='https://www.cl20.jp/portal/wp-content/uploads/2019/03/zagane.jpg'><img loading="lazy" decoding="async" width="300" height="225" src="https://www.cl20.jp/portal/wp-content/uploads/2019/03/zagane-300x225.jpg" class="attachment-thumbnail size-thumbnail" alt="" srcset="https://www.cl20.jp/portal/wp-content/uploads/2019/03/zagane-300x225.jpg 300w, https://www.cl20.jp/portal/wp-content/uploads/2019/03/zagane-500x375.jpg 500w, https://www.cl20.jp/portal/wp-content/uploads/2019/03/zagane-768x576.jpg 768w, https://www.cl20.jp/portal/wp-content/uploads/2019/03/zagane.jpg 800w" sizes="(max-width: 300px) 100vw, 300px" /></a>
</p>
<p>今回は、<strong>直径90mm、厚さ9mm、貫通穴（内径）19mm、材質はSS400</strong>のものにしました。手近にホームセンターがない場合、探せばネット通販などでも手に入るでしょう。</p>

<p>通販で購入する場合は、寸法や材質に注意してください。</p>
<p><strong>加工には旋盤を使います。</strong></p>

<h2><span id="toc2">旋盤加工</span></h2>
<p>丸座金の19mmの貫通穴を、高ナットとネジで固定して、旋盤にチャックします。</p>
<p>
<a href='https://www.cl20.jp/portal/wp-content/uploads/2019/03/sennban.jpg'><img loading="lazy" decoding="async" width="300" height="225" src="https://www.cl20.jp/portal/wp-content/uploads/2019/03/sennban-300x225.jpg" class="attachment-thumbnail size-thumbnail" alt="" srcset="https://www.cl20.jp/portal/wp-content/uploads/2019/03/sennban-300x225.jpg 300w, https://www.cl20.jp/portal/wp-content/uploads/2019/03/sennban-500x375.jpg 500w, https://www.cl20.jp/portal/wp-content/uploads/2019/03/sennban-768x576.jpg 768w, https://www.cl20.jp/portal/wp-content/uploads/2019/03/sennban.jpg 800w" sizes="(max-width: 300px) 100vw, 300px" /></a>
</p>
<p>今回の素材、丸座金の材質は、<strong>比較的柔らかいSS400</strong>というもので、<strong>粘り強いという特徴があります。</strong>このため、<strong>旋盤加工では、切れ味の良い刃物を使ってやる必要があります。</strong></p>
<h2><span id="toc3">継手が完成</span></h2>
<p>ファイヤーキャノンの接続部を、クランプ継手で固定する板材が完成しました。</p>
<p>
<a href='https://www.cl20.jp/portal/wp-content/uploads/2019/03/kakou.jpg'><img loading="lazy" decoding="async" width="300" height="225" src="https://www.cl20.jp/portal/wp-content/uploads/2019/03/kakou-300x225.jpg" class="attachment-thumbnail size-thumbnail" alt="" srcset="https://www.cl20.jp/portal/wp-content/uploads/2019/03/kakou-300x225.jpg 300w, https://www.cl20.jp/portal/wp-content/uploads/2019/03/kakou-500x375.jpg 500w, https://www.cl20.jp/portal/wp-content/uploads/2019/03/kakou-768x576.jpg 768w, https://www.cl20.jp/portal/wp-content/uploads/2019/03/kakou.jpg 800w" sizes="(max-width: 300px) 100vw, 300px" /></a>
</p>
<p>先ほども言ったように、<strong>SS400は粘りが強く、旋盤では加工しにくい素材なのですが、溶接性やロウ付け、ハンダ付け性は良好です。</strong>工作をする場合、こういった素材特性や入手性などを総合的に考えてやると良いでしょう。<strong>元の用途から外れていても、都合の良い条件が揃っていれば、それは適した素材だと言えます。</strong></p>

<p>さて、そういう訳で、完成した部品を実際にファイヤーキャノンに組み付けてみました。</p>

<p>頻繁に取り外す部分なので、クランプ継手で挟み込んで使います。</p>

<h2><span id="toc1">丸鋼とは何か</span></h2>
<p>いきなり「丸鋼」と言われてもピンと来ない方もいると思いますが、これは何かというと、端的に言えば<strong>鉄筋コンクリートの鉄筋に使われている、断面が円形・・・つまり円柱型の鋼材の事</strong>です。</p>
<p>さらにわかりやすく言うなら、科学動画の鉄アレイで氷を溶かす回で、<strong>鉄アレイの前に出てきた鉄柱を想像すると良い</strong>でしょう。</p>
<p><iframe loading="lazy" title="【実験】科学の力で最強の鉄球つくってみた！" width="1256" height="707"  data-youtube="eyJ0aXRsZSI6Ilx1MzAxMFx1NWI5Zlx1OWExM1x1MzAxMVx1NzlkMVx1NWI2Nlx1MzA2ZVx1NTI5Ylx1MzA2N1x1NjcwMFx1NWYzN1x1MzA2ZVx1OTI0NFx1NzQwM1x1MzA2NFx1MzA0Zlx1MzA2M1x1MzA2Nlx1MzA3Zlx1MzA1Zlx1ZmYwMSIsInZpZGVvX2lkIjoic1BYMGVSUjl0SncifQ==" src="https://www.youtube.com/embed/sPX0eRR9tJw?feature=oembed" frameborder="0" allow="accelerometer; autoplay; encrypted-media; gyroscope; picture-in-picture" allowfullscreen></iframe></p>
<p>あれは切れっ端、という感じですが、もっと長い奴がホームセンターに普通に売られている訳です。</p>

<h2><span id="toc2">安価な丸鋼</span></h2>
<p>まあ、写真を見ていただくのが一番でしょうか。</p>
<p>

<a href='https://www.cl20.jp/portal/wp-content/uploads/2019/01/marukou2.jpg'><img loading="lazy" decoding="async" width="225" height="300" src="https://www.cl20.jp/portal/wp-content/uploads/2019/01/marukou2-225x300.jpg" class="attachment-thumbnail size-thumbnail" alt="" srcset="https://www.cl20.jp/portal/wp-content/uploads/2019/01/marukou2-225x300.jpg 225w, https://www.cl20.jp/portal/wp-content/uploads/2019/01/marukou2-500x667.jpg 500w, https://www.cl20.jp/portal/wp-content/uploads/2019/01/marukou2.jpg 600w" sizes="(max-width: 225px) 100vw, 225px" /></a>
</p>
<p>こんな感じで、大きなホームセンターにいけば、ゴロゴロと鉄筋用の丸鋼が売られています。<strong>旋盤での加工素材として色々と優秀で、試作や治具の製作に便利です。</strong></p>
<p>ちなみに治具とは、機械加工などの際、工作物を固定して、工具の位置を誘導するための道具です。万力とかクランプも治具ですが、モノによっては自作が必要だったりするので、そういった際に丸鋼を使ったりします。</p>
<p>さて、<strong>機械工作における丸鋼の利点は、安価な事も挙げられます。</strong>910mmの規格品であり、25mmの直径の物でも、1000円もしません。<strong>こういった手頃さが、数々の機械装置を作る上での試作に実に都合が良い</strong>訳です。</p>
<p>ちなみに、手に入れようと思えば通販でも買えます。</p>
<p><div class="product-item-box amazon-item-box no-icon product-item-error cf"><div><p class="amazon-search-message"><a rel="nofollow noopener" target="_blank" href="https://www.amazon.co.jp/exec/obidos/ASIN/B079Y9RMW3/cl20_portal-22/">Amazonで「丸鋼 鉄筋」に関する詳細を見る</a></p><div class="amazon-item-buttons product-item-buttons"><div class="shoplinkamazon"><a rel="nofollow noopener" target="_blank" href="https://www.amazon.co.jp/gp/search?keywords=%E4%B8%B8%E9%8B%BC+%E9%89%84%E7%AD%8B&#038;tag=cl20_portal-22">Amazon</a></div><div class="shoplinkrakuten"><a rel="nofollow noopener" target="_blank" href="https://hb.afl.rakuten.co.jp/hgc/170ceeb5.7805da19.170ceeb6.693948bd/?pc=https%3A%2F%2Fsearch.rakuten.co.jp%2Fsearch%2Fmall%2F%E4%B8%B8%E9%8B%BC+%E9%89%84%E7%AD%8B%2F&#038;m=https%3A%2F%2Fsearch.rakuten.co.jp%2Fsearch%2Fmall%2F%E4%B8%B8%E9%8B%BC+%E9%89%84%E7%AD%8B%2F">楽天</a></div><div class="shoplinkyahoo"><a rel="nofollow noopener" target="_blank" href="https://ck.jp.ap.valuecommerce.com/servlet/referral?sid=3417081&#038;pid=885372973&#038;vc_url=http%3A%2F%2Fsearch.shopping.yahoo.co.jp%2Fsearch%3Fp%3D%E4%B8%B8%E9%8B%BC+%E9%89%84%E7%AD%8B">Yahoo!ショッピング<img loading="lazy" decoding="async" src="https://ad.jp.ap.valuecommerce.com/servlet/gifbanner?sid=3417081&pid=885372973" width="1" height="1" border="0"></a></div></div></div></div></p>
<p>まあ、運搬の問題などがなければ普通にホームセンターでモノを見て買った方が良いと思いんじゃないでしょうか。</p>
<p>さて、続いて規格や材質を見ていきましょう。</p>
<h2><span id="toc3">太さ</span></h2>
<p>丸鋼の太さは規格で決まっています。<strong>ホームセンターで取り扱われているのは、25mm、22mm、19mm、16mm、13mmあたり</strong>です。ちなみに25mmは以下のような感じ。</p>
<p>
<a href='https://www.cl20.jp/portal/wp-content/uploads/2019/01/25mm.jpg'><img loading="lazy" decoding="async" width="225" height="300" src="https://www.cl20.jp/portal/wp-content/uploads/2019/01/25mm-225x300.jpg" class="attachment-thumbnail size-thumbnail" alt="" srcset="https://www.cl20.jp/portal/wp-content/uploads/2019/01/25mm-225x300.jpg 225w, https://www.cl20.jp/portal/wp-content/uploads/2019/01/25mm-500x667.jpg 500w, https://www.cl20.jp/portal/wp-content/uploads/2019/01/25mm.jpg 600w" sizes="(max-width: 225px) 100vw, 225px" /></a>
</p>
<p>なお、専門店に行けば、もっと太い丸鋼も手に入ります。</p>
<h2><span id="toc4">材質</span></h2>
<p>ホームセンターで手に入る丸鋼は、<strong>SS400と呼ばれる材質が一般的</strong>です。<strong>柔らかい鉄ですが、粘りが強いのが特徴</strong>で、旋盤加工をする際は、バイトの切れ味が良くないと綺麗に仕上がりません。</p>
<p>また、<strong>SS400は炭素量が少なくて焼き入れができない鋼材</strong>となります。このため、硬度が要求される場合には使えない素材ですが、<strong>溶接・ロウ付け・ハンダ付け性は良好</strong>です。この辺も試作に向いた部分だと言えるでしょう。</p>

<h2><span id="toc5">実際に部品を作ってみる</span></h2>
<p>材料の話ばかりしてても仕方ないので、実際に作った部品をご紹介しましょう。</p>
<h3><span id="toc6">穴あけポンチのハンドル</span></h3>
<p>ホームセンターの丸鋼は柔らかい鉄なので、塑性変形して凹んできます。このため、<strong>使って行くうちに手に馴染むので、ハンマーで叩く工具のハンドル材としては最適</strong>です。</p>
<p>
<a href='https://www.cl20.jp/portal/wp-content/uploads/2019/01/pon.jpg'><img loading="lazy" decoding="async" width="300" height="225" src="https://www.cl20.jp/portal/wp-content/uploads/2019/01/pon-300x225.jpg" class="attachment-thumbnail size-thumbnail" alt="" srcset="https://www.cl20.jp/portal/wp-content/uploads/2019/01/pon-300x225.jpg 300w, https://www.cl20.jp/portal/wp-content/uploads/2019/01/pon-500x375.jpg 500w, https://www.cl20.jp/portal/wp-content/uploads/2019/01/pon-768x576.jpg 768w, https://www.cl20.jp/portal/wp-content/uploads/2019/01/pon.jpg 800w" sizes="(max-width: 300px) 100vw, 300px" /></a>
</p>
<p>というわけで、このように穴あけに使うポンチのハンドルを作ってみました。良い感じです。</p>
<h3><span id="toc7">ねじ部品</span></h3>
<p>ねじ部品として、ローレット加工を施してみました。</p>
<p>
<a href='https://www.cl20.jp/portal/wp-content/uploads/2019/01/neji.jpg'><img loading="lazy" decoding="async" width="300" height="225" src="https://www.cl20.jp/portal/wp-content/uploads/2019/01/neji-300x225.jpg" class="attachment-thumbnail size-thumbnail" alt="" srcset="https://www.cl20.jp/portal/wp-content/uploads/2019/01/neji-300x225.jpg 300w, https://www.cl20.jp/portal/wp-content/uploads/2019/01/neji-500x375.jpg 500w, https://www.cl20.jp/portal/wp-content/uploads/2019/01/neji-768x576.jpg 768w, https://www.cl20.jp/portal/wp-content/uploads/2019/01/neji.jpg 800w" sizes="(max-width: 300px) 100vw, 300px" /></a>
</p>
<p><strong>ローレット加工とは、滑り止めを目的とした細かい凹凸上の加工の事</strong>です。隠し包丁を入れたような菱形が並ぶアレ。</p>
<p>ただ、<strong>SS400はただの鉄なので錆びやすいという欠点もあります。</strong>ローレット加工は滑り止めを目的にしている以上、汗や皮脂を捉えやすく、すぐに錆びてしまうので、試作には良いですが、実際に使う場合には注意が必要です。</p>
<p>さて、今回は素材の話でしたが、<strong>機械工作、金属加工のとっかかりとして、ホームセンターで手に入る鋼材、丸鋼は良いものです。</strong>興味はあるんだけどどこから手を付けていいかわからない、という人用の、<strong>金属加工の最初の一歩</strong>としては良いんじゃないでしょうか。</p>
<p><strong>旋盤の一つも使えるようになっておくと色々と便利だぞ、諸君！</strong></p>
