Did you try going to "an extreme" like 100 rpm and see if chatter stops?(then work rpm up). Know on grooving on bigger diameters (on my equipment)higher RPM always tend to chatter.

pretty nice grinder for $1,500.00.

Our country is "awash" (over capacity) in used machine tools, look for good deals ,it is a buyers market (new or used). I would look all over the internet and watch for auctions(look on internet and or get on mailing lists).

6" inserted drill Thrust and Horsepower ???
Kevangel replied to crazy^millman's topic in Industrial Forum
gotta have some torque with that spindle HP (don't want all the horsepower being used up to drive the spindle up to high RPM) -
If its a motorcycle...Use to be don't over tighten on warm (hot)head (aluminum) or it may seize up when cold...that is one of the things that lead to heli-coils, head would galled to plug.

I don't think there is a taper to sparkplugs, think they shut-off on angle after threads, on motorcycles they use to have a round steel gasket..been awhile, BUT have a new autolite plug here at shop for truck and miked it with 50 mill mikes and no taper on it. Maybe your cyclinder head threads are damaged? or crud? use to be able to heli-coil them I think, if a tap did not clean them up.

I hang large shafts off the side of a Bridgeport mill in a big V-block and swing head of mill over to side above the v-block. You could also face end of round part with carbide cutter at that time...another variance is 2 v-blocks on table and use a right angle head in Bridgeport, but swing head over to side of travel first, then indicate head parrallel. Again you could face with carbide.

quote: So your worth can vary on your position but putting an owner in a bad position is not good for your professional career advancement. John, I have seen guys wait until they are halfway through a big mold and then "hold up the owner", I always told my employer "when this job is done, I'm done"..which has brought a big raise and "you are worth every penny"(wonder why they did not just give it to me?) oh well, my personal feelings are to pay people what they are worth, no more, no less..(and yes, employers can get stuck with people that are overpaid which won't last very long ..)

You will find out what you're worth to your "shop owner boss" when you give your notice, you may be worth more down the street.(shops are in different finacial conditions , i.e one shop is debt free and their customers pay more, or another shop is drowning in debt and their largest customer just filed bankruptcy and owner will never get payed, yet he has to still pay his bills and employees etc.)

After reading all of this.."How many machining people does it take to screw in a lightbulb?"

I am gonna have to type faster...

I would raise the surface that needs to be flat up, and place it on 3 tooling points(3 1-2-3blocks or or 3 gage blocks same height or make up 3 riser blocks of 1"dia. etc.) Part will not "rock" on a 3 point stance. Height masters are 3 point stance, my jig grinder is 3 point stance etc. Sometimes on prints they will call out where tooing points are, so that everyone checks the same way. Also I try to place points to reduce any sag in the part. Then indicate bottom side that is resting on risers.

quote: So what would you guys look at for around $70K or less I am curious about the Milltronics VMC where they upgrade to roller ways instead of linear...supposed to be really stiff, then I would add 24 HP 2-speed which I think gives 150 ft lbs and a 24 arm changer on the side. Made in the USA. Minnesaota (however ya spell it)

one of my old customers had a Haas, then added a new "purple" Johnford , then the next new one was a new Haas again..(they kept all three)

Isn't that in the Machinery Handbook??
-
Assuming you bought it oversize, I would rough it out and then finish machine it, with stock having been takin off both sides, etc. I never have stress relieved alum.??? especially T6 which is heat treated grade. Have straightened some alum. parts in hyd. press...(I would use flood coolant and sharp cuttings tools also)

Been that bad for over 20 years...with all the downsizing you would think it would get better, but some smart folks went back to school and are doing something different i.e started construction business and one machinist became an R.N. etc
