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 ?? .

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

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 ?

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 .

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

http://www.ingersoll-imc.com/en/products/Fast-Break_Catalog_Updates.pdf 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 ?? http://cdn3.bigcommerce.com/s-jr5hrcn/products/108/images/244/8_boring_ring_2_1_1_1__75637.1406657410.1280.1280.jpg?c=2 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 .

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 .
