【加工動画51】旋盤のねじ切り送り停止装置/How to easily cut screws on a lathe

The technique of threading away from the chuck/lathe headstock becomes more important when making an internal thread with an internal shoulder. Deeper the internal threads with a shoulder more difficult threading becomes as the threading operation is essentially blind. Reliance on stops and indicators become the only means to gauge what is happening inside the bore. This is a common mechanical feature on optical and similar mechanical parts.

[@TheMetalButcher]

I rely on indicators for high speed OD threading anyway, so not much added stress.

Hello From Australia, I am a machinist as well. What a great idea in cutting such a high-tolerance thread. I wish I was closer to, Japan as you have such great made tools & machines. Love the professional Video editing. I have subscribed & Liked. Will watch all of your Channel.

[@RobertLBarnard]

Brilliant solution and expertly executed, as always.

[@rupunzel6299]

Simpler and easier way to single point thread direct up to a shoulder would be to invert the threading tool (upside down) or use a LH threading bar with the lathe spindle running CCW for right hand threads or CW for left hand threads. Set the carriage stop at the threaded shoulder end point, cut a thread relief groove with a radius bottom, then thread away from the shoulder/chuck. Been doing this method of single point threading for decades. No issues, No drama, No stress from worrying about running the threading tool into the shoulder or chuck.

[@Gnomebitten]

this won't work with a threaded on chuck when you can't run it in reverse

[@rupunzel6299]

@@Gnomebitten Correct, this will not work with a threaded on chuck. Risk of un-screwing the chuck while threading is very, very possible. Question is, how many lathes with proper thread cutting abilities are produced today with threaded on chucks (mini-lathes do not count)? Fact is, most any versatile lathe made today will likely have a D series cam lock spindle. Threaded on chucks are are serious limitation in many ways. Threaded spindles for chucks and such date back to the 1930's and before as the lowest cost means to attach a drive fitment to a lathe. Back in those pre-WW-II days, lathe chucks were not common. What was common were face plates, dead center on the headstock and tail stock with the work driven by a lathe dog or clamped to the face plate.. Add to this those lantern tool post with HSS tool holders.. which are a problem waiting to happen. Notable, there is no 29.5 or 30 degree threading in-feed commonly practices by machinist trained in America circa WW-II.. Yet, the threads are absolutely good as in this direct cross feed example.

[@martinchabot_FR]

@@rupunzel6299 threaded spindle nose were still common up to 1960, my 50's lathe got one, and I won't trust it in reverse (brake stop is already dangerous).

[@rupunzel6299]

@@martinchabot_FR Much depends on what the needs are. Vintage lathes with threaded on chucks today are most often hobby lathes today that are limited in their capability. This limited capability also means techniques and tooling used matches the limitations of these lathes. If these limitations are acceptable, good enough. If not, a different and more modern lathe and associated tooling and techniques/methods are needed. This is not an absolute thing, it is much about needs and the tools that can be applied to meet a specific need.

Je suis abonné et apprecie toujours autant les vidéos. Merci et compliments. Salutations

[@elisancere3578]

Great for cutting new threads not to sure about repairing and chasing old threads. I take a left hand threading tool and turn it upside down on center and thread towards the tail stock and you get right hand threads. Just because I hate threading towards the chuck.

[@IL_GUERRIERO_TRUCKDRIVER]

what a great idea! congratulations! a friend from italy!

[@dimtt2]

Excellent idea and construction. I really enjoy your videos. Did you have to test various springs acting on the compound to find the proper ones for the job? From what I understand the springs should generate much higher forces than the axial cutting force. Otherwise the cutter will stall and ruin the thread.

[@SwaplampJapan]

Thank you for watching. yes. If the spring is too weak, problems will occur as you mentioned. I used a spring that has a large amount of deformation, which is mainly used in mold press machines, and I think it pushes with a fairly strong force to cut a screw of this size with a sharp blade. Some adjustment can also be made by adjusting the position of the turret feed handle.

[@timkelsey8249]

[@Hiro-lm4by]

アイデアももちろんですが、チップを使わず手研ぎでねじ山側面がヒビ割れ（細かいむしれの様な）ない様に加工するコツはありますか？ 刃先の角度をねじのねじれ角に合わせてみたり色々試しているのですがなかなか動画の様な綺麗な仕上げ面にならず悩んでいます。

[@SwaplampJapan]

ご視聴いただきありがとうございます。 バイト（ホルダー式かロウ付けか）と材料の素材によっても抑制する方法は異なりますが、 ムシレが原因かカジリが原因かビビりが混じっているかを見極める必要があります。 切れ味の悪さや切り込み深さが原因で生じているムシレなら切れ歯を鋭くして仕上げパスを増やします。 すくい面付近の逃げ面と材料が擦れる摩擦でカジリが生じている場合は、高粘度か極圧添加剤入りの切削油を使用し、すくい面付近の逃げ面を油砥石で仕上げます。逃げ角が大きすぎる場合も圧力が集中してカジリが生じたりビビりが混じる場合があります。大きなネジの加工では逃げ角を殆どつけない専用バイトで仕上げる場合もあります。

[@Hiro-lm4by]

@@SwaplampJapan ご丁寧に返信頂きましてありがとうございます。 バイトは若い頃からステッキバイトに自分で研磨した板バイトを取り付けて使用しています。 最近ブレーカーチップ式のバイトも使用していますがオールマイティーに使えるのはやはり板バイトと思い試行錯誤しており質問に至りました。 304等では綺麗に仕上がるので、切削速度も関係しているかと思い切削条件も模索中です。 例えとしてM10 P1.25で320rpm~500rpmを目安に加工しています。

[@SwaplampJapan]

ご返信ありがとうございます。 私は経験が少なく本を読んで得た知識ばかりで恐縮ですが、 ステッキバイトは突っ切りのような主分力のみの加工には有効ですが、 ネジのような送り分力が大きな加工の時には左右にはビビりが出やすいこともあります。 ヘール式ホルダーの場合はヘールの左端に刃先があるので主分力でも送り分力でも力が掛かって変形したらホルダー自体がヘールの頂点から右斜めに捻じれるのでその傾向が強く出てしまうことがあります。 私もM20以下やインチネジは使い勝手が良いステッキバイトを研いでネジ切りしますが、それ以上ではロウ付けバイトを使う場合が多いです。 ハイスのバイトでネジ切りをするのであれば回転数は低すぎて悪いということは無いので、回転数は問題無いと思います。 304は綺麗な仕上げ面が得やすいと思います。ハイスの刃先の完成度を見るならSS400のようなムシレやカジリが特に生じやすい低炭素鋼で見極めるのが良いと思います。

[@Hiro-lm4by]

@@SwaplampJapan 自分もステッキバイトでは逃げがあるので仕上げ寸法も出しづらく本来であれば固定式のバイトに板バイトの組合せも試したいと思っているところなのですが、現在の職場は加工はあくまで保全作業に係るおまけの様な扱いでして、元加工屋の私自身の探究の為だけにバイト一つ購入するのもなかなか難しいところです。 ロウ付け超硬バイトでも色々試したいのですが残念な事にダイヤモンドホイールベンチグラインダーも高額な為購入して貰えず、自分で製作したディスクグラインダーのダイヤモンドディスクを取り付けたシャフトを旋盤にくわえてエンドミルやバイトまで研いでる有様です。

[@Hiro-lm4by]

@@SwaplampJapan 回転数に関しまして被削材の直径が細くなる程低回転での仕上げ面粗さが増すイメージだったもので。 回転数＝切削速度を抑えればビビりは減る代わりに仕上げ粗さが悪くなると言う認識でした。

[@maryou2501]

動画のスタート時、「この送り速度でねじ切りィ⁉︎」とびっくりしましたが、まさかこのような方法で加工時間が短縮出来るとは… 恐れいりました…

[@301069patxe]

I am always afraid when I make threads on the lathe and I finish, as long as the thread allows it, reversing the tool and the direction of advance of the carriage. But this mode can be a good solution for me. I'll try it as soon as I can. Congratulations on your videos, as always waiting for the next one.

Hello sir, absolutely remarkable video, of great quality. Would you be so kind as to provide me with some information. Concerning the springs, do you have a link to order them or at least what diameter of wire did you choose? Another request concerns your threading tool, again a link for the body and the inserts would be very useful to me. I will try to carry out your work which will also make it possible to disengage the feed in the case of traditional carriage. Thank you in advance for a positive response and good luck. P.K.
