  1. We only use Karnasch tools for copper for our electrodes. We order out of Germany for them and get as small at .2mm ball nose tools that are typically 0/-.01mm
  2. We don’t use that here, but everything is decided upon in Germany. We have a tool library called JANUS that feeds S&F data to NX and tools in holder to Vericut for use there. We don’t have a tool crib, but we pull up the tool info by tool number and have a picture of the holder and all the length info for the mounted tool. No idea if there is a US based team. We’re the small fish of the company.
  3. They are an awesome resource. Never had a problem and we always were satisfied with what we got. Bonus is that we got the cores back so I could use it for other work.
  4. Trepan Specialties? Always had good results from them.
  5. I’ve been working late and haven’t gotten the old workstation fired up yet. If I remember correctly the OSG line is now UVX (it wasn’t quite as good as the SUS line was in my opinion). I also used HSMAdvisor via the app to dial in tools to maximize life and productivity with my tools.
  6. I’ll have to look up exact tools later when I’m at my old shop computer, it we used a line of OSG tools that were discontinued. They replaced them but they weren’t as good. It’s for aerospace and had variable helix. The old lone was their SUS line. I can’t remember what they were replaced it with. I ran accupro tools with no issues in lots of 15-5PH condition H1025. TiAlN coated or Altin will give your best life overall. Ran Hanita Varimills at the last aerospace shop I worked and got pretty decent results. High axial/Low Radial gave us the best life and performance for our tools. Coated carbide was the second key for success.
  7. We had a similar shaped but, but much smaller is 15-5 H1025. Gcode programmed it and we ended up running a SNMG 15deg lead holder for some pretty solid performance and tool life. I’d have to dig out my programs to see what S&F we ran, but we had excellent chip breaking with this approach. We used a false center and tooling spud because we had to mill flats in it after turning plus some other mill work. Ended up sawing off most of the spud and turning the end radius to a near match. Did pinch turning on a different part and it wasn’t an issue normally. Only issue I saw was poor forging a that required more material on an interrupted cut to be removed and the tools not liking that extra .07 I had to move Z to get a good clean up.
  8. Quick answer: Yes long answer: the no go requirements are the same for 3B and 2B. The go member has different tolerances. 3B being a tighter tolerance can be used to buy a 2B requirement.
  9. Use Carbide. I used to run a ton of 15-5 @ H1025. No manufacturer has S&F info for cobalt or HSS drills for these materials. I ran the Accupro solid drills hard and they held up great. Also had phenomenal success with Titex drills using thru tool coolant.
  10. I don't have access to the alloy that I used to machine. Al-Ni-Bz, but that seems about right. I'd run up to 3000SFM in it and rough at .018/.025IPR all day turning. Stuff loved a chip load to be put on it or it got gummy and hard to shear with the tool. Especially milling. Gummy pushed over burrs were a huge problem before I started pushing the tools. I want to say it was C63000 alloys, but that data is stored on an old thumb drive that I can't get access to right now. Gcode may may have more insights on it. We talked about a similar alloy a while back that he was working on.
  11. This should be similar to, if not the same alloy, that we ran at Stadium. It's gummy and like a high chip load to break a chip. I'll see if I can find some of my old files, but I ran around 200-400SFM and typical Al chip loads. You might find some feedback data in our old emails as well.
  12. We've used Walter and YG for small holes. Usually metric sizes, but the TSC works well for our work. Cast iron, 15-5 and various grades of AL.
  13. I'll try to take a look tomorrow at the NMV to see what cycles are where on that thing. It's not a machine I run or deal with. The guy who does asked me if I worked with Macros and could help. Told him I knew just the place to ask questions and hopefully get steered in the right direction. Thank you for pointing me in the correct direction.
  14. I got asked at work if I knew how to probe a flat surface and have the control figure out the adjustment to update the axis offset so the surface is flat. I understand the basic concept of how to achieve this, but I lack the experience to wrap my head around the logic that needs to be written for something like this. This is for a NMV to allow us to prove the A-axis flat instead of indicate the surfaces while setting up the part. Any help or general direction someone can point me to would be great. I don't run this machine, but it's a good opportunity to start learning it.
  15. I've been looking at their Kaizen Foam for my personal tool boxes at home and work. Budget friendly and easy to work with from everything I've seen. No experience to give you real world feedback though.
  16. Thanks for the feedback. Got the sump cleaned out after 2-4 years of collecting aluminum. ( no one remembers when it was actually done last) Went from maybe 200 gallons in the machine to over 400 flowing freely. Got the Sikaflex in the machine and the sheet metal stopped dripping. Now we just need to replace the rubber curtains that channel the coolant back into the tank and I think the bulk of my lake creating issues will be solved. Baby steps on getting them back to fully functional. Preventative Maintenance has not been a priority in the past... I call these two machines "Pigs" for a reason. They are big, smelly, messy things that do produce amazing things.
  17. I started this learning cure this week. Programs are set, but I need to cut my insert costs. Not sure that button style insert mills are the best for removing a large step of material. Looks to be shallow high feed style toolpath. I started turning on TSC to hopefully improve things. Any other tips anyone can share?
  18. That's awesome. I've been working on getting people to look at things this way at the new shop and only when I produce results do they say....hmm.....maybe we should have done this sooner. Way to go, I never really mind when I miss that fast of a show. I know it'll happen sooner than later at that production rate.
  19. I've got leaks in two of my mills. I need to replace the caulking at the sheet metal seams. Two Millac 853PF-5X lake generators. I'm taking at least one down on Monday to clean the sump and take care of much needed PM's. I've used GE Kitchen and Bath II in the past after our Daewoo Service technician said it's all he uses for sealing machines. I'm just afraid of it not being durable on the bottom bed of the machine for any decent amount of time. Parts run for 4-9 hours and the chips hold the coolant over the seams. Any recommendations for what to apply to the Machine?
  20. Gcode recommended this company to us at my last shop. They did our 40Taper Haas with no issues. http://www.don-spindlegrinding.com/ Cost us around $800 I think the owner told me.
  21. Thank you Tim. I was hoping you would have something to help. Have any other resources like books and such I can purchase? Not always able to use my phone while running production to work on educating myself. We do not have G5.1 running on any of the programs in this cell. It is all G05 P10000. I started adding the R values and it helped, but nothing like removing the G5 did for the 3 axis roughing. The G5 P10000 R1 took 48 min for the bulk of the roughing to complete. With the roughing run with no G5 called out I got all the roughing, including the 5 axis roughing that had G5 P10000 R5 called out done in 48 minutes when we closed for the day yesterday. This cell has struggled to catch up and break even on demand, so taking what looked to be 45min of roughing cycle out of a 3 hr program could be a huge gain for us. These machines have the 5 efficiency levels in the control. The two are not set the same, but I do not know if that is due to previous crashes and issues. No one really knows why one is at level 2 and the other is at level 3. Can you give me anything more to explain the different Q values with the G5.1? I'd like to try possibly implementing that as an option for trying to reduce cycle times while maintaining the accuracy. I'm not sure I understand the differences between Q1, Q2, or Q3 well enough to even venture an experiment to see how well it would perform.
  22. I'm trying to get a grasp on the variations of G05 and its best implementation on a Fanuc 31i-Model A5 control. We do some straight up 3 axis roughing leaving .05-.100 stock for 5 axis roughing before finishing. I'm wondering if running the G05 P10000 is causing us to leave a lot of time on the table. The code is calling it out for every tool. This includes drills. I've read thru a few of the other posts about G05,G5.1, etc. and I'm not exactly sure if what we are doing is the best way to use the tools/machines. This is on a pair of Okuma Millac 853PD-5X mills. We also run this code slightly tweaked on an OKK K1000(?). I've been dedicated to a new part project on the Millac so I'm not touching the other 3 machines in this cell. Also tasked with learning the new Mazak Vortex e1060/V6?. Nothing like this challenge moving from Haas mills and Doosan lathes. Any web resources that help break this down would be appreciated. I'm trying to read and understand usages while running the machines currently. I've got the Fanuc manual downloaded on my phone for reference, but there's only so much I can glean from that.
  23. Definitely had this conversation with my supervisor. It's amazing how the perception changes when you say use cash. The set screws I found are about $.60 each. I need about 1000 per machine just for the primary subplates. Maybe we'll win the battle with management that wants parts faster and less O/T to make deliveries. Just pre-calling tools is saving significant time. Trying to find a few other ways to minimize delays due to handling and clearing the tables for the next part. Can't avoid some of it though. I want to thank everyone here for the ideas they've shared over the years. I haven't had many I can contribute, but this resource has helped me grow in amazing ways. I hope one day to be in a position to give back what has been given to me.
  24. I'm working on getting plugs in place for the subplates on the machines. We loose 10+ minutes to clearing them out so we can lay the next big piece of aluminum on the table. Not to mention bolt installations and clamp changes. Not going to be "cheap", but 100pcs per month adds up really fast. Also need to rebuild my tool application info resources now that I know what they run at this place. Drilling with Coolant fed drills in Al at 1200RPM/F4.6..... It hurts watching that much cash be burned. Didn't think I'd be waiting long to work on the low hanging fruit, did you G?
  25. Thank you Doug. I figured it should be that simple, but I'm not one to mess with stuff that works without asking the experts first. 8-10 seconds beats 45-60.
