I'm not very pleased with my knurling attempts, but this video is very promising, one of those that may promote me to Home Shop Machinist one day😄My question is: what are the most common angles between horizontal plane and knurling wheel axis? This because my toolpost is standard four sided slotted prism which make height adjustment of the round tool bar more demanding. In other words: I need to know How much I will have to move knurling tool holder up and down in my tool post to compensate the pivot of the contact point?
@mikelevyonline6 күн бұрын
If you stick with straight or box knurling, there's no need to readjust center height. For diamond knurling, the angle between the vertical plane and the plane of the knurling wheel is pretty much up to you and the diamond shape you prefer. You could start with +/- 30 degrees and see how you like it. The center height difference between the two settings will depend upon the offset of the knurling wheel contact point from the center of rotation of the tool shank. It's possible, of course, to fabricate a more sophisticated tool in which the contact point of the knurling wheel is coincident with the center of rotation.
@andjelkocirkovic43886 күн бұрын
That was quick, thank you very much! I appreciate your detailed answer. As the contact point between knurling wheel and the material must be at the height of the material axis, it seems that I have to put some insert under my tool post to provide space for tool height alteration..Thanks again.

Nice Appreciate all of the detail, but you missed one I view as critical. The circumference of the part compared to the tool. When the lrg is divided by the sm, the more decimal remainder the more chance of double skipping.
@mikelevyonline19 күн бұрын
You may be confusing this with form knurling. This is not form knurling, it is cut knurling. Cut knurling will track on any random diameter.
@baconseggs18 күн бұрын
Seems to me that the pitch distance has to go around the circumference within a tolerance or your threads will double step regardless of method. Unless, possibly, the tool slips slightly when rotating so that the pitch stays consistent…
@murrayedington28 күн бұрын
18:55 surely the second cut for the diamond pattern requires the spindle to run clockwise, so that it cuts rather than forms the thread? I note it is doing so in the second pass.

If making you own holders for cut knurlers l would suggest machining the cutting relief into the body of the holder. For dovetal type tool posts l personally always prefered to set them at 0° offeet as my insert tooling was then at the proper orientation. My HSS tooling was also ground to be in the correct orientation. All of my threading and chamfering tools in HSS as well as special grooving and trappaning tools for O-Ring grooves were finish ground on a surface grinder in fixtures purpose made.
@mikelevyonlineАй бұрын
That idea has merit-I also like to position my tool holders at 90 degrees to the spindle axis, however if I want to change the clearance angle of the cut knurler I would prefer to rotate the tool inside the holder rather than rotate the entire tool post.
@mpetersen6Ай бұрын
@@mikelevyonline The primary reason l started doing it was to eliminate the adjusting the tool post constantly. I had my own A series tool post and l ground the inside face of the tool slot parallel with the faces of the dovetail. The drawings we would get in the last years before l retired started coming in with chamfers anywhere from 10° to 45°. So l made up ones with 45, 30, 25, 20 and 15°. For threading tools I had blocks for 60°, 29° Acme and 60° offset 30° for internal threading. For odd angles and form tools l used a block with a rotating head with a 7° clearance angle built in.

We had a cut knurling setup for the Hardinge HLVs were i retired from. One thing that would sometimes need to be allowed for was extra diameter on diameter being knurled. For quick and dirty knurls on jobs that were non spec. Personal or special hand tools being made for production use. Knurled heads on screws etc. Hand knurlers are nice too. But cut knurling beats all methods hands down

Excellent vid 😊 One question. If you think of the knurled part like a gear or spline, will it sometimes create like a half knurl or tooth? Or is it always cutting a full knurl? Or is there a way of calculating based on the material diameter?
@mikelevyonlineАй бұрын
My experience is that it will track on any random diameter, thus always cutting a full knurl.
