Im no machinist but I helped my great uncle build planes, who was one. Every time I used and kind of a chuck, be it drill, drill press or lathe he always made me tighten every side of it. That way you are centered, and your work piece or drill bit will not spin. Keep up the good work and I hope this may help you in the future.

It looked like a chuck where all the jaws close at the same time at the same speed. If you're using a 4-jaw chuck you usually need to tighten them individually for more precision. 3-jaw chucks (and apparently 6-jaw chucks; never seen one before) usually have a simultaneous tightening mechanism. But I do agree with you. I mostly use 4-jaw chucks for their higher precision expect for some quick turning (replacement screws, etc)

I've been knurling for 30 years, and have always had problems with knurls that have to be forced into the stock from one direction using the tool post and cross slide. Once I got a scissor style knurl, my problems went away. Scissor style knurls don't apply any force on the tool post. The problem I would get is I would get double hits, where the knurl would hit in between the previous mark as the stock rotated, thereby doubling the knurl pitch. With a Scissor style knurl, this is eliminated by clamping the two knurls heavy into the stock BEFORE turning on the lathe. In this manner, the first dents are deep enough so that on the next rotation the knurl falls right into the previous dent, thereby eliminate the double hit. Try this and you will like it. It is much more dependable - for me anyway.

@manuelh.6055
6 жыл бұрын
The diameter of the tool does not have to match with the workpiece. And it does not line up since the two wheels have opposite "profile". And because the profile is simple lines it does not matter where they overlap. Hope you did understand my explanation.
@superdau
6 жыл бұрын
It is simple lines but I don't understand how it would line up in all cases. Let's for arguments sake say, there's a total of 10 lines on the circumference of the nurling tool and it's circumference is exactly 10mm, so each line is 1mm wide. What if the workpiece has a circumference of for example 10.5mm? You can't put an integer number of 1mm lines on that. You end up with 0.5mm "left over".
@geoffcunningham6823

superdau the lines are at an angle, so the tool just moves up along the rod enough to get an exact match each rotation. Edit: autocomplete error

Angled or not doesn't matter. You must have an integer number of lines on the workpiece or else they just won't match up.
@philipwilliams5429

my understanding is that with sufficient pressure on the workpiece the knurling tool works into the nearest rational "harmonic" and is stable there; the diameter of the workpiece is usually much larger than the pitch of the knurl, so this harmonic condition is easily satisfied.... it takes more than one revolution to get there, though.

Do the diameter of the knurling tool and the diameter of the target piece have to be a multiple of each other, and does it just work with no assumption on the diameters ? Also I don't understand how it can make a consistent pattern while the lathe is feeding. Does it just work ? Does it align itself with the previous pattern or something ?
@MilanDupal

The diameter/girth of work piece and knurling wheel have to be multiple....Yes and No. There are a knurling calculators available for download or online, but I never used them. The friction force while knurling process act the lubricated knurling wheel pattern slide to the corresponded already created groves. Important is to apply enough force during start phase. Yes it does align itself with the previous pattern during horizontal progress. Just take a piece of scrap material and try knurling yourself to get necessary "feeling" and practice!
