Every one of my co-workers using an SJ-410: “Nice tight spot” (spins handle all the down slamming probe into surface with excessive pressure) “now we can slide along that surface” (proceeds to measure massive curve without profile compensation) “and they you go, we’ve checked the surface finish” (the 2 micron tip was snapped off weeks ago by these Ogres so everything always checks good)...
all depends on the material you're cutting/your tools and inserts/feeds and speeds and depth of cut. we have parts that we have to hold 4 micro faces and 8 micro bores and ODs all the time. most of these are done on lathes. realistically you can you can have a good of a finish as you want as long as you try hard enough and put the time into it. iv ran parts with 1-2 micros on the faces many times. all this is done right off of the lathe with the tool, no lapping or polishing or anything.
@@OwnerOfOwn I learned on the job. Went from cnc operator to quality manager. I was running the joint like a navy ship at one point and the guys didn't like that. Maybe don't send out so much shit that you let slide by without asking me first!
@@pocket5751 hell yeah man, glad to hear that as an operator that finds it hard to settle for "good enough" I might find my way into a quality role one of these days
@@OwnerOfOwn I couldn't deal with the filth. I was very particular to clean my machine through the day and pay attention to everything. Other guys would leave iron on the machine and wonder why it's running like shit the next day.
7.67µin = 0.19µm in metrical system
Working for titan must be a hell of a day worth of work...i mean your working for a god like figure..lol

metrology in highschool, with a machine class. Let's get the dem's to print another trillion to put a machine shop in every school!
What is that in Ra?
it was Ra, but in µin (microinches). 7.67µin = 0.19µm
@@MM-up5mc metric makes more
sense
@@sorenkasten1071 only for people who use metric system.
@@MM-up5mc right
After all these things that had gone wrong using both in a project..... I wonder if....
Runout in my living nightmare
how are you measuring that? in my book Ra 7,6 is rougher than raw material!
That is probably micrometers; we are measuring in microinches.
@@travisjarrett2355 that would explain it alot!
@@travisjarrett2355 this is the correct answer. We measure roughness in micro meter .
Inspector time
no way it gotta be more to it
What about the pinky nail? I’ve heard the old timers talk about buying off surfaces with that? Ha, no offense old timers!
What a dale pitch lol 😆
Nice video . Would be nice if they made a fully automatic one similar to a probe to check it before it even leaves the machine .
i am interested anyone recognise wich first stage that part belongs to
Mitutoyo Surfstand is a great way to measure hard to reach features
Cool tech. What is the finest surface finish one could expect from a mill or a lathe?

Thats freakin sweet!
Wow wow
👌
Oh the flash backs to working in a quality lab. So many guys never knew how to do this.
yeah, we need metrology classes in fucking highschool. There are too few american's who know how to do this.
