i think also every walter grinder is busy
Is anyone interested in exchanging ideas and info on the Walters?
We have two of them in the shop, power 500 and vision. We also have toolcheck. Not my favorite machines around, bit of a PITA to calibrate, and fix when they break. I suggest making a hard drive clone, and replacing CRT monitor for some generic LCD on power. I might have schematics for attachiing MPG somewhere if anyone cares, always wanted to do it, just never had time. Also if you're using NT4, update to SP6, and newest walter software. They finally fixed that silly network set up they had going there.
We also have about 40 Rollomatics, if anyone wants to talk about them. We grind carbide only.
I'm interested in knowing what packages everyone uses.
I'd like to know a little more about using the corner radius offsets in package 1.
I have successfully been able figure out how to blend the radii on the end, but once in awhile still having some trouble blending the radii on the diameter of the tool. I've attempted to use the offset under the Corner Radius page under the Geometry menu. with little to no success.
Any help is appreciated
Don
could anyone tell me how to set the saw program to make multiple cuts or passes on the top of a sawblade? eg I would like it to take .15 mm first time around and then .15 mm second time around without reseting the machine
still having trouble with the rads?Originally Posted by Donald
are you using mgm grind or hollow grind?
Donald if you have the front where you want it just make the OD a little larger or smaller to blend . Move only a few tenths til you see what you end up with. Good luck. Be patient and it will work fine.
Hi, well I guess I have you all beat, I have been on a walter now for about 14 years, and we still run the first machine we purchased, its a 45 helitronic. We also have a first generation 400 power machine still running dos (thats all it can run) and a larger newer power production, or at least thats what they called it when it first came out, now I think they would class it as a power r, and we also have the first diamond machine in north america as well as a helicheck that aint worth a pinch of beens.
Packages, when I do run the machine, I love to use expert mode, but I use that, p1, p3, p4, a little p7, & p52 (diamond machine) and the occasional p2, I hate p2 and I dont do much in the form or ball ends or corner rads, they are always a pain in the rear to get perfect blends on these machines. Never learned p32 but I hear its pretty cool.
We also run a rollomatic, I like this machine for basic tools and large runs, but the walters are great for smaller orders and tricky tools.
cool site you guys have here, I like it
do you use your rollomatic for micro tools?
i heard they are good machines for small tools?
the smallest tools i've made on a walter was a .032 ballnose tapered endmill
and i've made 0.032 drills. lots of fun.
i use pk2 and pk32 all the time, i could give you pointers on blending the rads and balls if you'd like, but if you've been doing this 14yrs, you probably would'nt want to hear it.
i've only ever met 1 person on the walters longer than myself. i'd love to share ideas.
I spend most of my time looking after guys running the machines, trying to keep a handle on things, and fixing the machines when they break down....which lately has been quite frequentlyI only really get into it anymore if its something tricky, or if I'm training one of the newer guys on something, or if its got to be done YESTERDAY LOL. For the most part, I use pkg.3, 4 and expert mode. I'll be honest with you though, when it comes to blending a rad on a ballnose, or corner radius endmill, I suck at it because frankly, we seldom do that sort of work in our shop so I never remeber the little tricks, but thats where cybergrinding comes into play, its easy to see what to do when you can over correct it by a mile to see what the outcome will be. Hell, I cant imagine running efficiantly without cybergrinding anymore, especially for something out of the norm, or tricky, which is why our older machines almost never get used for manufacturing anymore, mostly just regrinding on them.
As for Rolly, we like Rolly for small stuff, but so far I think the smallest tools I have done are around 1mm for some step drills, and some 2mm 3fl center cutting endmills. I wouldnt even atempt that on the Walters, not with the spindles in those machines, they are terrible.
How long have you been at it on the Walters?
I have been using Walter Grinders for 12 years now. We curently have 9 machines. 1 HMC 600 Vision w/ Loader, 4 HMC 500 Power Productions with cyl. loaders, 1 HMC 500 Mini Power, 1 HMC 400 Power and 2 HMC 400 Powers w/ loaders, there are only a few of these our there. My software experience is wide. P1,P2,P3,P4,P5,P8,P32,G code or Flex Prog,expert mode and Tool Studio. I have also done a lot of maintenance on all of these machines. I enjoy programing special projects and trouble shooting problems. I would be happy to help answer any questions that I can. We are also allways looking for operators/programers for solid carbide specials.
I have 30 years experience grinding cutting tools on manual machines. I have about a year on some Huffman 85s. We have 5 Walters and I have been able to get about a months training and a month of running them. I would love to get more time but always need to fix tools on the manual machines that the guys on the cncs say they can't get. Anyway the question I have is about tapered end mills with a radius on the corner. I am trying to figure out how you get the angle and diameters to come out right. I have tried setting up the tools with diameters called out and the length. The angle doesn't even come close. If I call out the angle and give the diameter at the back or at the front nothing still is even close. I am finally getting close but am having to lie to the machine with false numbers. This is completely trial and error and wastes a lot of time and tools. I want to learn what I am doing wrong or if there is a problem with our software.
Thanks for any help. It would be greatly appreciated
