Anyone compacting they shavings or swarf from their machining procedures ??
Curious to the PRO's and CON's of compacting the waste to a brick/billet shape as just dumping it into a bin ands selling as shavings .
We produce mainly in 303/304 SS and aluminum and from time to time brass and bronze , at peak production we process around 4000lbs of bar stock a month of SS and similar with aluminum .
Are these machines worth the investment ??
What style are companies using , the chip conveyor style where each machine has a stand alone compactor , or are companies running one compactor and compacting as needed .
-
that should do it I have used a U drill in the past to drill the hole and open it up to a rough ID prior to running a bar thru it for size .

did you check the cylinder that rotates the probe arm down ?
and I agree with Machineguy 100% probing is way faster than manual touch-off

I've only used it for brazing, can't comment on machining. The fumes are gnarly though!
sure you are not thinking of silicone bronze ??
part of me is wondering if it is similar to what we typically call 660 bronze , if it is the stuff is real nice to work with , for tooling anything suited for aluminum would work very well if the properties are similar , Aluminum Bronze is a whole different beast .
-
Have to agree with Sticky , when comparing 304l to 18/8 the base materials are pretty much the same .

Cool some good info
We run 303 SS 90% of the time and we go lights out Monday night thru Thursday night so tool life is a big concern . All the machines have SS filters that we clean out once a month , we have done lots of tooling tests as well and pretty much have the grades that work the best for our products .
Part-off tooling is a issue at times , every so often we smoke out a tool on the night run , put that is one of the costs of going lights out for 14hrs .
Right now I think the CNMG style may be worth trying out on certain jobs we only get a couple hundred parts before the insert looses it's nose radius .
With drills and such the coolant holes don't seem to clog with SS but on Aluminum I have lost a few tools due to the holes packing up and getting clogged and going dry .
Cost wise it's something we have yet to go over still , and see if the gain is there for the extra $$$ and hassle of running coolant lines to the tools .
Thanks

Curious if anyone has experience with lathe tooling that is ported . One of the local reps brought in some flyers with part-off blades and tool blocks with coolant ports , and also seen some CNMG style holders with the clamp ported and plumbed for coolant .
My questions are
is there a increase in insert life ?
Do the tiny ported holes clog up over time ?
has the tooling failed due to the coolant ports ?

Do you mean a tapered bore? I'm not seeing how you could drill a hole on an angle with only 2 axis unless there was a live holder with adjustable angle involved. Even to do a tapered bore you would need to have your static holder on an angle.
No it was a straight hole on a 15deg angle or so , it may of used a live tool , this was close to 15yrs ago or so . there was a video of the part on youtube I came across it one day years back .
-
when I was doing tons of hydraulic manifolds and port blocks that would have come in handy at times , sure beats trying to position the part for a one-off procedure , I have seen a lathe drill a angle hole using 2 axis movements back in the day , the part was something Honeywell was producing and was being demoed at a local trade show .

every shop I have worked in since I started in the trade( 28yrs fulltime) has had a HydMech , and guess what everyone of them did their job day in day out with no issues .

This tool is a straight up brute. No other tool compares for hard metal cutting imho.

that is similar to the Iscar Plunge milling cutter we have on 303 SS in plunge milling application we did not see a lot of difference in insert life over a standard SPCT type insert
-
SECO cutter with a 45deg insert with a wiper edge , use to use several different sizes of them years back , they work very well IMO .

2nd for Chick we have them for our double vises

Dorian tool offers one and a company called Nine9 has something as well
-
as many others have stated picking out the lead thread and then try to uncoil the heli-coil with some needle nose vise grips.
-
what about grinding it ?
-
we run Harvey Tooling on our ROBO DRILL using Volumill and have had really good success with tool life , smallest cutter is either .012" or .015" .
-
what does the program look like when printed out , we run twin spindle lathes everyday . for me the hardest part with working on the B side is making sure I get the correct positive and negative values in the correct positions .
-
do you use a chucking ring ??
last shop I was at we used one of these when truing up and boring soft jaws .
in my current environment all our turning centers are now equipped with collet chucks on the A and B spindle , as 90% of our products are under 2" O.D.
when I have to bore a set for the HAAS TL1 we have I chuck a small crop in the hard jaws , size the boring bar , then switch over to soft jaws and bore to required OD and bore depth needed to hold the part .

Thank you I will forward that to purchasing and see if they can source something similar locally , seeing we are based in Canada we cannot purchase thru McMaster Carr due to tariffs and such .

It is a few years old, but not much has changed with their newer stuff. Mostly our part timers do the marking, tho none of them complain much about painting the solution on parts before marking....or wiping the stuff off. Pretty painless procedure. Marking anodized parts...looks way cool and no need to paint the solution on.
We have a similar machine I believe it is close to 20yrs old and still does what it is supposed to do with little to no issues . I know it was just serviced as we looked at replacing it and there is not a lot of change to the design so we did some refurbishing and will continue using it for marking anodized parts and cutting small items .

Last shop I was in had 3 HAAS,s 2 of them where only a year or 2 old , the lathe we bought a few month before I left was a headache , hard drive crashed a few weeks after buying the machine Getting decent service was a joke as the techs are total hacks!!! . The one tech wiped out a brand new tool probe on the lathe , another tech did not tighten up all the mounting bolts on the power chuck .
My current shop has 3 Doosans and I am very impressed with the machines and the service we get . $$$$ well spent .
Thru spindle sealed collets
in Machining, Tools, Cutting & Probing

Does anyone know if you can get a 3J style collet that is sealed ??.
We run them on our the "B" spindle on the turning centers and with thru coolant I am still getting shaving between the collet body OD and the ID of the collet chuck .
Over the course of day the collet opening size is reduced due to the chips , and eventually it does not open up enough to grab the part during the transfer procedure .
Ideally I am looking for a steel body collet with the slots filled with rubber to help prevent this issue does such a item exist ?? .
