別の動画で道具が綺麗で素晴らしいというコメントがあったが、本当に道具をケアしつつ作ってる、知り尽くしてるという感じを受ける。また手先も凄く器用と思う。
Try dressing the wheel before grinding. Less vibration, smoother grinding. Slow down chuck rpm. Vibration from this will affect accuracy. Keep up the good work.

This is great. I have learned so much just from watching your videos. Thank you for sharing!
It is wild to me that High Impact PVC is enough for the jaws to load up on. The level of TIR improvement is astounding!
スゲー‼️
これからも色々なアイデアを期待してます。
That moment when your overly strange desire to clean the lathe is justified!! I can't even watch people working with sandpaper on a lathe... Like!
Greetings from the US! I really appreciate all of your editing. It's the perfect combination (Most of the time lol) of quiet cinematography and craftsmanship and the real life sound and experience of your work. Very well done! I don't machine but oddly I find comfort in these kinds of videos. ASMR? Keep up the great work!
Another great video! I love how you make your own project-specific tooling!
As always, clean and dedicated work. Nice video - thank you for sharing !
今回は粉塵よけを作る動画でしたか！？
Once again it's all about the skill.
You never disappoint. 👍🖖
Simply, amazing job! You are truly an inspiration.
Thanks for showing the method. I learned a lot from it.
Parabéns pelo excelente trabalho ,muito caprichoso quanto ao cuidado pó gerado ao se fazer a retífica !!!
super precision...
What a difference. Great video.
Thanks for sharing.
Eccellente soluzione ad un grave problema, bravo!
Impressive again. That made a huge difference. 👍👍👍
Beautifully done.
Sim mestre você está de parabéns também pela disciplina e organização de trabalho show 👏 obrigado pela orientação 🙏
Excellent work Sir
Perfect technique. Thank you
すごすぎる‥‥
very impressive result
Great, as usual. Thanks for sharing
Obrigado foi grande ajuda para. mim resolveu um grande problema.
Very neat job
Nice job, only advice I could add is that you should have run the grinder on your final size until it "sparked out" which means that you can run it in and out in the same position and it doesn't spark at all. Also linear shaft is actually not very round it's not designed for rotation so I doesn't really need to be. That's why you see better runout with the milling cutter shank.
😯Excelente resultado!!!!👍👍👍👏👏👏👏
Exelente trabajo amigo me gustó cómo centro el plato quedó bien 🙏
Gostei muito bom! 🇧🇷
Отличное видео😁👍
Thank you for shearing
Brilliant, thanks
Смотреться с удовольствием! Спасибо!
Good Job 👍
Gud work!
Thanks
Все ничего но пластик для такой задачи не подходит от слова совсем. У него нет ни какой жесткости. И тем самым вы ни как не устраните микролюфты в ходах самих кулачков.
А вообще у Вас классный канал есть на что посмотреть. Желаю удачи в развитии и новых творческих побед.
Muy bueno el video e interesante .
Durante años he visto trabajar a muchos torneros y nunca vi que rectifiquen o controlen el estado de las mordazas, además, las empresas de reparación de tornos, (las que yo conozco) tampoco lo hacen.
ពិតជាល្អណាស់love your videos
Question:
When you grind with the wheel and keep the jaws locked at a specific radius, wouldnt the radius from where the jaws are held be imprinted on to the jaws and cause uneven gripping on larger parts?
Thank you for watching.
That's right.
Basically, I tighten only at the mark position, so the contact surface between the internal scroll gear and the chuck body is unevenly worn.
Therefore, when grasping, the center of the claw moves to the opposite side of the mark by the amount of wear.
Since I gripped and polished in this state, when I gripped an object with a different diameter, the claw facing the mark touched the material at the center, but the other two claws contacted at a position other than the center.
This will fix the material on the side of the mark if the diameter is smaller than when grinding, and on the opposite side of the mark if the diameter is larger than when grinding.
This time too, the chuck was worn out and worn out, so the core of the thin linear shaft shifted 0.01mm toward the mark.
Perfekt!
cuando voy a rectificar las mordazas, lo primero que hago es mirar varias veces como centrar un eje o una barra rectificada una copa mandril está fabricada para hacer apriete de las tres copas con igualdad de fuerza. trato con dos copas si no da centro apretando con tres. no es recomendable apretar de una sola copa porque la sujeción es más débil y la pieza puede zafarse con un corte exigente. si por desgaste, definitivamente no da centro de ninguna forma, ahí sí procedo a rectificar. un secreto que me revelaron es: según usted sujete el aro para fijar las mordazas, así mismo sujetar las piezas que en adelante vaya a maquinar. con una tolerancia de una milésima de pulgada de error, queda agarrando.
Ваше видео как бальзам на душу
amazing，a hotshot
The grinding wheel is ruff.
It's not the jaws that are out, it's the chuck threads.
Your preloading the slack out from the wrong direction! If your grinding the surface of the chuck jaws for gripping a outside surface you need to preload the chuck in that direction!
Thank you for watching.
The inside of the chuck was ground by applying force in the gripping direction on the inside of the jaws of the chuck.
Scroll gear contact is correct.
これってチャックが比較的新しい場合は良いけど、爪の溝が擦り減ってガタツキあるとテーパーつくよ。
It is like taking your lathe to the dentist 😷
冒頭部分でシリンダーゲージで
フレを見ていたので
3本爪のスクロールチャックで
どうやって芯出しを！？
と思ってしまいました
странно, что для зажима кулачков, вы выбрали не стабильный материал. если бы взяли металл, нагрузка была бы более корректной.
Спасибо за просмотр.
Спиральный патрон изнашивается неравномерно в той части, которая соприкасается со спиральным механизмом, поэтому, когда старый спиральный патрон затягивается, положение кулачков патрона меняется.
Следовательно, полировать можно более аккуратно, если материал обладает прочностью, но не имеет жесткости для деформации.
@@SwaplampJapan спасибо за объяснение, вы видели ранее, что я не токарь, а электроэрозионщик)
Greek letter phi Φ is not the same as diameter symbol ø
Over all good job.
👍👍👍
精度出るなら俺もやりてえ
I wonder if there's a way to get the jaws flat.
Why didn't you use inner clamping method when you are grinding those jaws? Sorry for being a new machinist
Thank you for watching.
Since the jaws of the scroll chuck have backlash, the parallelism of the jaws differs when gripping the outer shape and when gripping the inner diameter.
When grinding the inside of the nail, it is better to grind while grasping the outer shape.
About 5um runout on my Poland Bison 160 Chuck out of box.
うちの爪でも試してみようと思います！
Interesante.
Давно хотел увидеть классно !!!
The last runout chuck is 0.02mm or 0.002mm?
Thank you for watching.
1 scale is 0.01mm, so it is 0.02mm.
なるほどこうやって修正できるんですね。ハンドグラインダーは必須なんでしょうか？芯押し台にドリルチャックだけでは不足でしょうか？
失礼します。砥石にも回転を与える必要があるかと。ちなみに私はCBNで切削しています
おそらく高価ですよね？できるだけコストを抑えたいのですが。
@@move3137 そうですね…中古品を再研磨しています
@@ak.8418 差し支えなければ伺いたいのですが、ホルダーはどういったものをお使いでしょうか？
ご視聴いただきありがとうございます。
爪の研削には日立が販売していたツールポストグラインダを使用する方法が主流であったと思いますが、
販売終了のため、ハンドグラインダーを使用する方法で行いました。
おっしゃるような方法（回転しない砥石）は試したことがありませんが、刃物台に単に砥石を固定しただけの場合は超微小送りで行う必要があり、相当の時間が必要になると思います。
Ещё один шаг к медитации 🤓
Малой продольной подачей, под углом шлифовал кулачки?
Спасибо за просмотр.
Я разрезал параллельно.
Деталь, захваченная патроном, сзади тонкая и легко деформируется, а кончик толстый и трудно деформируется, поэтому считаем, что угол наклона кулачков будет таким же, как и при захвате материала.
You loaded the jaws in the wrong direction. Grinding inner sides requires a ring *inside* of the chuck, like you would clamp a workpiece. Grinding outside with a ring.
Thank you for watching.
It is fixed in the same direction as the grip of the material.
@@SwaplampJapan Ah! Sorry! Now I see it.
what about outer surface of jaws
Thank you for watching.
If you want to shave the outer surface of the jaws of the chuck, you'll have to grasp a ring-shaped object from the inside and shave it.
can you please tell the background music name .
Thank you for watching.
Background music is New Land - ALBIS.
thank you very much :)
@@SwaplampJapan
sorry but this is a big mistake
don't grind\turn that kind of jaws
those are for roughing and that's it
for precision turning you have to buy jaws that are soft and must be turned every time to clamp the piece precisely
in addition, by grinding the roughing jaws you remove the cemented layer and for strong tightening you do not get the precision in the finish
as long as you limit yourself to aluminum it's fine ... but when you have to make an H5 on a small piece ... it's a problem if the tightening doesn't take place because you grinded the jaws
professional turner rule #1: never modify the equipment ^^
개쩌네요 ^.^
为什么不用刀车一下？磨的会跳动少？
有更簡單的校正方法嗎?
感謝您的收看。
還有一種方法是將卡盤的鉗口從邊緣削去幾毫米，然後將鐵環夾在那裡。
@@SwaplampJapan 我的三爪夾頭鉗口裡面被磨掉了,前口套還會導致鉗口公差太大,現在在想辦法校正公差
😜😜😜😜😜
id rather have the clap.
АХП.
Bonjour , A quoi sert le montage de l ecrou avant la rectification ?
Merci d'avoir regardé.
La position des mâchoires du mandrin à volutes n'est déterminée qu'après le serrage de la poignée du mandrin.
De plus, si la pointe de la mâchoire du mandrin ne saisit pas l'objet, la mâchoire ne peut pas être raclée parallèlement à l'objet saisi.
@@SwaplampJapan Ok merci , superbe musique ....
سلام خوبی سنک سلند داخل سنگ میزنم داری میشه معرفی کنی ازگجا تهیه کنم
Demasiado complicado.
0.02 mm means zero?
👍👍👍
