I make a holder for TNMG carbide inserts

I bought, cheaply when I got it, Kennametall's TNMG carbide inserts.
However, I didn't have a suitable blade holder for them, so now I'm going to make one.
In the end, making the holder was quite challenging even though its geometry is simple.
There will be strange angles and challenging setups for the workpieces.
In this video I use:
- Weiler Matador SV (1972) Lathe
- Schaublin SV-51 (1955) Milling machine

good job finno

Kiitos Esko! Hienoa harrastamista! Itse tein just poruslaitteen sorviin... tsekkaa video jos kiinnostaa... 👍🏻🎅🏻🇫🇮

Hi ESko, great video nice holder.
To tighten the collet I think that iff you dril 2 holes on the outside in the backplate of the colletholder in 180 degrees, so you can put a pin in the holes for the contra force you need to tighten the collet. Trough this way you push no force on the gears of the lathe.
Make a nice pin with a good grip as a part for the colletholder.
You don't have to bring switches in low gear to have contra force and after tighten the collet no more return to the gear you have before.
I think it saves time and the RPM stays equal on your settings.

Great work!!

Nice part to make in your own shop. Those holders can be expensive! Thank you for the interesting and sometimes "exciting" video. You had me on the edge of my seat when you started the slitting saw into the workpiece. lol

Itse en oo viittiny noita tehdä vaikka CNC koneella ei ois juuri konstikaan. Tasojyrsimen teko kiinnostaiskin kun kiinan jyrsimissä aina palat eri tasossa. Toki kiinan palatkin luultavasti kaikki eri kokoisia.

I know this is going to sound weird but I love this guys videos can you get them in English.

[@dubmfg]

I actually find just turning on Closed Captions and increasing the video speed to work great.

[@santopezzotti730]

Really looks like a great project

30 minutes in, you mill the sides off the tilting vice, to clamp it at 10° in the fixed vice?
I don't understand why! You could bolt it to the table, and use its tilting feature !!!

Soititko taustaksi Rosvo-Roopea ja "Jo Karjalan kunnailla lehtii puu"? Taustalla kaapissa näkyy ilmeisesti muuta kuin koneistukseen liittyvää kalustoa - olisiko funktiogeneraattoria, oskilloskooppia yms. elektroniikkaukkelin kalustoa?

[@FinnoUgricMachining]

Rosvo Roope, Ellin Polkka ja Karjalan Kunnailla. Nitä tuosssa soitan. Elektroniikkavälineistöä on enemmänkin syynä on OH2GTK.

I preferred your earlier videos. I'm sorry but your last few videos are much too long. I'm looking for a short background, some video and explanation of the design and how you will hold the material and set up angles and then highlights of the actual machining and then done. For something like a TNMG insert tool I'd expect more like 20 to 30 minutes of video.

It is always a tough decision to split a video in 2 or even three episodes. I was about to split this one into three but then, for some reason, I decided to make it a single shot.
Splitting the video is probably the least destructive method to make shorter videos. Other widely used methods are speeding up the performance slightly and omitting actions that seem to be not worth showing. Both of these may make the video shorter but these do not enhance the content itself.
I like to keep the tempo in my videos quite slow.. This is the very reason I always have the diverse sections in the videos. Those enable the watchers to skip over painfully slow or exhaustively boring parts of the video.
I do not intentionally make the videos long, they just become that way all by themselves 🐢
