【加工動画25】旋盤で六角穴/How to make a hexagonal hole with a lathe.

旋盤で特殊形状の六角穴付きナットを作りました。
六角穴は簡易的な治具を製作してロータリーブローチ加工と同様の原理で加工しました。
安全に考慮した上でアイデアの種にしていただけたら幸いです。

I made a specially shaped hexagon socket nut with a lathe.
The hexagonal hole was made by making a simple jig and processing it by the same principle as the rotary broaching process.
We would appreciate it if you could use it as a seed for your ideas after considering safety.

バイトが自由に回転できるバイト固定治具を作って、テーパがついた六角形のバイトを偏心させて工作物に当てることで、切削抵抗でバイトが工作物と一緒に回転しながら押し切って、六角穴ができるというワケか。仕組み考えた人天才だし、自分でやってみたいってなるのもすごいワカル。

[@myasu3589]

六角の切削工具の形状をよく見ると根元が細くて頭が大きいのがわかると思う。根元側が細いのは、その分を偏心させる為でしょう。同時に先端が1番大きいのは仕上げ寸法であり先端の芯の位置が真芯に成る事も示している。原理としては回転に併せ先端の作用点が次々と変わり先端の当たっている面が偏心分細かく上下する事により切削される。で動画説明に原理を応用とあるのと動画みた限り工具や受けの部分(ホルダー)での偏心は見られない。どう偏心させたのかは取り付けたのが工具取り付け台と言うのが答えでしょうね。これなら切削工具自作でも偏心の設定など好きに決められるので既製品に縛られず探求出来ますからね。

Used the very earliest model of that same tool on a Warner & swasey bar feed turret lathe when I was 18 years old in 1978 at Winters Performance Products York PA. It is kind of old technology but still effective, and if done manually requires a good bit of feed pressure enough to wear you out before 8 hours is up...

[@ronjenkins6674]

In the mid 00s I was the machinal engineer, draftsman and EDM programmer and operator for a small job shop. I made broaches like this on the wire edm out of carbide rods. It didnt' take long and the setup was easy once I understood what was happening where the tool hit the hole. It was hard to convince the boss that I needed two passes on the carbide to keep it from chipping. BTW we are the same age :)

[@BeachsideHank]

I like the gloved hands slowly appearing in the scenes, so Ninja- like.☺

[@randr10]

Okay, it took me a bit to figure out why you weren't just feeding the broach straight into the hole without rotation, but now I realize that the one degree offset makes it so that as you feed, the rotational force of the lathe is converted to linear force and thus the broach is only cutting at one point on its circumference at a time. Very interesting idea. This would be like using a chisel to bore a hole by wobbling the top of the shank with your hand after each hammer blow.

[@hinkepank1239]

Thank you very much - you explained the need of the rotation to me. Very good point (I got lost thinking about it :-) )

[@ianunderwood3850]

Yeah,it's a strange phenomenon, but when I broach on a lathe,with it square,not at 1degree, if I try to just press it in the hole,it won't go. But with it rotating (even though they both rotate together) It pushes straight in. Ive never really understood it, it must be physics or some such magic!

[@world-karma9127]

@@ianunderwood3850 although they are rotating together the cutting face will have a different speed to the material, could this be what your missing,

[@ianunderwood3850]

@@world-karma9127 no,the broaches we use are square or hexagonal in shape, free spinning on a bearing,and applied with force. As it touches the workface they both rotate at the same speed(as the broach is free spinning on a bearing). If it didnt rotate at the same speed the hexagon shaped broach would basically cut a round hole.Its probably possible just to press it in to cut the hex,but would take a lot of force,but with them rotating together,it presses in relatively easily, it doesn't make much sence.... and it's difficult to describe without seeing it,I've been an engineer and machinist for 30 yrs and this has always baffled me!

[@battlebeard2041]

Rotary broaching tools are designed to rotated eccentrically (at a 1-2 degree angle usually). When a roaring workpiece contacts a point of the hex broach, the tool begins to spin, but the slight angle built into the rotary broach holder makes the cutting tool “wobble.” As it turns at a slight wobble in relation to the workpiece that is spinning straight, the tool point furthest into the workpiece digs a little into the metal. Forward pressure from the tool feeding into the workpiece as it spins creates a chiseling sort of effect as each of the cutting points contact the workpiece. The tool is ground with a taper along it’s length and a slight concave to it’s face so minimize the cutting forces to the points and sharp front edge of the broach. A pilot hole close in size to the flat-to-flat width of the hex must be drilled first otherwise the force required to push and dig the metal away would be much to great for the machine to handle. You need somewhere for the metal to go. Either you need to create a chipping action to cut the metal out with a rotary broach and drill, or you need enough of a relief space beneath the hex you are creating for the metal to squish down into it.

[@hamasmillitant1]

thanks. i knew the angle was key but i was wondering how it could not contact all parts of circle, wobble makes sense although a little counter intuitive for a novice like me i guess

[@user-kr3pq8ht9j]

なるほど。 傾いていることによって最も工作物に近い6角形の1点が工作物に当たる、触れた部分が切削抵抗によって回転方向に動く(回転が同期する)。6分の1回転すると最も工作物に近い頂点が入れ替わり、そこが工作物に触れ切削する、の繰り返しってことか。 理解するために最も重要なのは偏心のある回転によって工作物に触れている頂点が入れ替わるってところだな

Skilled work! I haver considered making a rotary broach tool, and watching this I realized that the bearing does not need to be tilted. Your way to angle the tool post seems better, the bearing can be much sturdier. This rotary tool should also have other uses for odd jobs, it could easily be driven by a small motor as a slow sturdy spindle.

[@KamikazeWombat]

I enjoyed this video, but I fail to see the benefit of doing the broaching on a spinning lathe? Seems like it would do the same if done without the lathe spinning.

[@erikisberg3886]

@@KamikazeWombat The tools are much simpler and cheaper than stepped broaches. I have some stepped hex ones, as far as I can remember they were rather expensive. And the smaller ones are easy to break. Making a tool for a rotary broach is fairly easy in a D-bit grinder or similar.

[@KamikazeWombat]

Sure that part makes sense, but what about the extra trouble he went to for bearings so it could spin with the lathe? Why not just press the tool forward into the part with the motor turned off and therefore not have to build it with bearings?

[@erikisberg3886]

@@KamikazeWombat You can do that in very soft materials, but a rotary broach cuts difficult stuff much better. Forces are much lower, advantage is also that you can do it in the same setup keeping everything lined up and in bottom holes. Also it is sometimes the only solution when the hole is shallow. Stepped broaches require little force, but only work for trough holes.

You made your own rotary broaching tool. 🙌 People hate rotary broaching mostly when they don’t understand it I think. I never get to use rotary holders when I broach because I’ve nearly always got a specific orientation of the broached feature. Static broaching sucks less of you can EDM/grind the broach in half (or get one made that way) and index the workpiece.

Видел несколько видео с такой прошивкой, но в живую её никогда не видел. Её сделать можно или заказать у кого? Если делать то не знаю размеров. И да ещё вопрос, сталь ею тоже прошивают или только цветные металлы? После кузницы детали обычно всегда кривые и требуют особой обработки (в оправке, на оправке и прочие неудобства). А если как в видео деталь, то идёт долбёжнику и нужно делать канавку под выход инструмента.

Essentially offsetting by a 1 degree angle make the tool wooble relative to the hole being cut so it acts a bit like a single point tool scraping a tiny metal each revolution.

[@shirothehero0609]

Take a new wood pencil that hasn't been sharpened (the hex variety) and then either get some clay or something similar and poke a round hole in it with a cylindrical pen. Take the pencil and sort of "wobble" it in a circle while pushing down lightly - that's essentially how it works, just with a sharper metal pencil and metal instead of clay. Literally what I've done in the past to help visualize what's happening much slower.
