lathe work turning threading

Trading life for money 7 mins at a time. This is a job I was doing at work. Pretty simple, just faceing, rough turn, finish turn, threading, and debur. .150 doc rough pass, .065 finish pass ,700 rpm .006/rev feed. 1"-14 thread material is free machining steel non leaded 2620? maybe. Lathe is a later '90s Fortune 1640. 16" swing 40" between centers. Has a auto feed stop feature. Used here with roughing passes only. Its great for staying away from those hot flyin chips. Its a sweet machine! vid taken with a flashplayer. I could never get those perfect clear closeup shots like some vids on here but it came out pretty good IMO. HA I took the camera to work to show some vids of my dog to some friends, since it was in my pocket aready decided to take vid of this work on the lathe to see how it would come out. let me know what you think. One other thing. Why does it take so long to upload a vid. Am I doin something wrong? This vid took 5 HOURS to upload. Is that normal? 5 hours?!

@joleenmorganjohn I work with this guy who complains every time i conventional mill something should i start climbing

[joleenmorganjohn]

@ramcharger1907 Yeah, start with climbing out from under the bosses desk! ,Chris.

Hello I am a high school student trying to Learn about lathe work and I have no idea where to start

[joleenmorganjohn]

@awk77hockey Well honestly you've started allready. The desire and interest to learn is were you start. Try your school and public libreary. Take out all the books you can find, ussualy the older the better. Ive found newer books assume the reader is allready coherst in the trade and they leave alot out. Search the internet for Southbend's publication called "How to run a lathe" and Atlas's version "Lathe operations and machinist tables". Probaly the best beginner books ever printed.

Awsome vid im studying mechanical engineering and in my country the school make it sucks. I look forward to get out of the college and start having hands on experiences

@welshboy118 As far as that sucky job, the customer accepted it. witch is all that matters.There are so many variables that could cause a bad finish. machine condition,tool geomotry,feeds and speeds,material traits,coolants,and somtimes the alignment of the planets LOL Start with basics, properly ground tool,correct feed and speed,rigid setup like close to the chuck and supported by the tail stock if work extents more than 3 times diameter,tool hieght centered,sometimes slightly above center.

@welshboy118 Glad to hear of new blood in the field. Machinist is kindof a dieing trade. Try to get under the wing of an old machinist. Listen and observe. Not nocking your school but a year under the wing of an old timer is worth years of schooling. I'm getting the feeling that you work with 0.15 mm? whitch is just under .006 of an inch. 0.15 inches is a little over 1/8 of an inch. Thats a pretty big tollerance. All the tol. in my comments were inches .00010" is .0025mm

[welshboy118]

@joleenmorganjohn im studying mechanical engineering i passed nvq1 now doing nvq2, ..

and our tollerance is 0.15 +/- lol, but 0.0010 that is insane, how did it end up ? u said it sucked lmao ?

any tips for me to like i have trouble getting a good finnish on the lathe??

@alehax27 Thanks for the answer. I figured it was something on my side.
