Knurling from two Sides - The Perfect Knurling

In this video I'm making a big shaft with a knurled section in the middle. This footage is from a failed restoration video recorded in July 2021. I cancelled this restoration of an old and very rusty 25kg dumbell that was sent to me by a subscriber from Germany. I thought I could still share the footage of the making of this shaft, because it was very special to knurl from both sides with an overlap. I've never done or seen this before anywhere. One very critical point for a successful result is definitely the runout. The part has to run 100% true on both knurlings. Therefore the only way to achieve this was to turn the part between centers. As I don't have any lathe dogs in the shop I decided to fix the part with a dead center with a threaded shaft. Like that the part was running true and was also secured. The knurling went very well and was looking really perfect, also the overlap was almost not visible anymore.
I hope you like my work and the video.

That centering is so smart! The threads only provide compression, and the cone provides alignment. Very cool, will file that away.

@mymechanicsinsights Жыл бұрын

A center drill type B would actually work even better. Then your dead center angle wouldn't run into the thread. Also for heavy machining it might get tricky to get the part loose again.

Beautifully done knurl. We're fortunate enough to have a dedicated machine for knurling. We drop the part into a fixture (no clamping required) and the two 140mm wide knurling tools knurl the shaft in a couple seconds. But then again we're talking mass production so it's apples and oranges. In any case, your knurl looked fantastic.

I started watching your channel a little over 2 years ago, with no knowledge of lathes, mills, bench grinders, or much of anything else. Initially I thought that the lathe was operating with a computer program because it was so precise, but my brother informed me that that was all manual control. The precision of you manually shaping metals or lathing them blew my mind! But it turns out that you are Swiss, and thus your amazing skills are hereditary and passed down from generation to generation! The greatest mechanics experts in the world!

The regular Knurling tool not cutting cheap , go by introduce pression into the parts . Two tools require cutting oil. When tapping using spiral flute you need to support the tap end ,whit center light , recommendation tapping whit machine tap or hand tapping, are good to! Have a nice day from : Brampton , Canada.,
