The machine we use most is a Power R. It is a very good machine, also. Is your 'R' machine windows or DOS driven? I would like to hear more about your machines.

My machine is Win NT CD 11, i work mainly in P1,P2,P3,P6,P32
for the moment, i also use cybergrinding.

Our Woodtronic cnc5 loader is a machine for grinding tct sawblades , we can put 60 sawblades in the loader.
i now have 2 years with the machines .

Sounds like we are running about the same things. You don't use pkg 4? I've had 2 years on them too. Maybe we can help each other out with any problems.

No i dont use P4 for the moment , its easier and faster to use
P32 and you also have more power for grinding complex profiles
i think you have a limitation in P4 that the steptool only can get bigger in diameter and that limits me , the dxf loading is a nice thing since all drawings comes in dwg or dxf files , so its just to cut out you profile from the drawing and load it into P32 and your
almost done.

on the other hand in P4 you can gash the inside rake angle on the differnt steps so you dont get negative rake angle on the smaller steps in diameter, but there is for sure more nice things in P4 that i dont know about .

if you have any problems just tell me , and i would do the same.

I think all of our Walters are in the 500 series. We have the mimi, powers and loader.
I sure hope they make the sofware more user friendly.

been using these machines for 7 years now.........one mini production....one power-r and one power-r with disc loader.......use pkg's 1,2,3,4 and beginning to use pkg 32.....we mfg alot of high performance drills and step drills using pkg 3......and use pkg 4 for our form tools.....I've manufactured 2-flute ballnose tools on pkg-4 holding a .0394 dia. +.0000/-.0001 and a length of .0669 with the same tolerance intersecting into a 59 degree 34 minute +/- 5 minutes(included) in lots of about 50 at a time......using our mini production (with glass scales) and very nice univel metal bonded diamond wheels.......I'd really like to get more in depth into pkg 32..........

I have a few questions about pkg #1. I've been running this package mostly the past several weeks. When hired in the took me back and said here it is... make it run.

Have been running a lot of 3 and 4 fluted corner radius ( anywhere from .009 radius +/- .002 to .050 radius +/- .002) the machine will hold this once its dialed in. But whatg is the best way to adjust for the misblends on the diameter and ends? (tangent points of the radius)

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

still having trouble with the rads?
are you using mgm grind or hollow grind?

john leon
01-25-2007, 05:32 PM
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 ;)

cb1
05-02-2007, 07:03 PM
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 frequently :( I 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

Or re-measure your wheel?

12-11-2007, 08:36 PM
We are working in p2. Maintenance has been out numerous time and gone over the machines. Have tried lots of combinations on the wheels and still no luck. If we put in the right numbers for d1 and d2 and put in the lengths for l1 and l2 the resulting cone angle is not even close. We are getting tools now but the numbers aren't even close to what they should be. It does this on 4 machines and in cybergrind. I would really like to find out if we are doing something wrong or if there is something we are missing.
Thanks.

Hi

we have a couple of walter grinding machines with Helitronic Tool Studio and one PC with Cyber Grinding software. (Really gooooood machines)
And i need some idea how to make simple manufacturing drawings or export it to some 3D CAD software.
The software self can not make any drawings or export it to 3D files like .stp .neu .prt
The drawings are just for customer. ( marketing)

Thanks for ideas

I am trying to grind a 6 tooth solid carbide t slot cutter, 3 teeth right hand cut with 5 degrees right hand axial flute and 3 teeth right hand cut with 5 degrees left hand axial flute. Cutter is .297 wide with .020 radius on front and back of each tooth.The front and back face of cutter has 1.5 degrees dish with 2 degrees side clearence. Can this be ground completely in p5? (first time using p5)
Right now I am piecing it together with p4 , p6 and p32 wich seems to be some what of a hassle but it will work for this time around.

cb1
07-31-2008, 09:31 PM
i make those the same as you. we dont do enough of them for me to figure out a different way. i find that pk5 works best for simple regrinds. i dont spend enough time in pk5 to mfg anything. so, my response is to suck it up and piece the tool together. or if its going to be production, then spend the time to find a different way. (and let me know when you do)

CNC savvy but not grinding. What's al the P1,P2 Pkx, p32 stuff. Where can I read about this.
I have been grinding various things on my 4 axis CNC SX3 with some success.
I can rotate the head to all sorts of angles thru about -30 to +120 degrees.
I've been using a 50mm CBN wheel on my carbide cutters. I do a fair bit of stainless steel. I can hand sharpen a 0.4mm drill OK. See picture.

the PK stuff just refers to the software packages.
Walter split up the software into "packages", PK1 is for endmills, PK2 is tapered tools, PK3 is drills, PK4 is step tools, etc.

Just curious is anyone using blaser hc10 oil in their Walter grinder with a 600psi power fluter on it, if so have you had any bad effects from breathing the finely atomized mist ? (we have a mist collector on it but it's not hooked up to any type of duct work) Alot of the mist is still suspended in the air when the enclosure door is opened, I think thats when i seem to be breathing it in even though i try to hold my breath for a while after i open the door.

cb1
06-18-2009, 10:05 AM
ya, i hate that.
we have hooked up external mist extrators to our machines, they work ok, but you still get the mist in your face. we usually wait 5 or 10 seconds before opening the door. i am sure its not good to breath it in, just like any other CNC or oil mist, you should try not to get it in your eyes, on your face or breath it in.

Well one of my first problems is when I grind certain counterbore step drills I have been getting overtravel alarms, but I can run another piece that is the exact same and it will run. When this happens, it will completely run all the program, but when it gets to the finish pass on the counter bore (step clearance 1) thats when I get the alarm. I have tried everything I can think of to figure this issue out, but to no luck. I know that there is still alot of bugs that Walter is working out of this software and there is suppose to be a new update coming out in about 3-months.

I would like to upgrade the ToolStudio calcul speed and download, when there's a change of value on the program. Is it possible to change the Ram card on the CNC computer? Do I need special Ram bracket ?

There's always bug on the anime schema of the tool, part missing, lag etc.. Is there any other way to get it faster and better quality than changing the RAM?

Thank you all.

there is a way to move the files back.
but..... a corrupt database may have more problems. the best thing to do is create a backup every month or so, and just re-install the database if the hard drive goes bad.
send me a privaite message and we can exchange emails, and Ill send you some info to move the files.

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.[/ Hi I have been with a heletronic power walters cnc for 5 yrs..only have pkg 7 and did some pkg 4..but my question is..is there a trick in setting up program so intersecting point of radius blends the way it should..it is somewhat passible but not accurate. Ty for any ideas or help on this..be much appreciated! I Guess site needs longer explanation more characters! Should I program a false width of diamond wheel and radius size? Walters Heletronic Power Package #7 Carbide tip milling cutters...cutting brass..cutting with smear finish!!

We have a heliotronic 400 machine. I would like to make a backup of our hard drive since the drive itself is 11 years old.

The drive is a 1gig seagate. They don't make those any more and the machine/ comp/ bios won't recognize any of the larger drives.

Any help would be greatly appreciated.

Thanks

Hi All,

i'm very new and 1st time on CNC tool grinder. i'm using Walter helitronic basic tool grinder. Currently i'm setting up the department for tooling making. I'm facing a lot of problem when setting up this dept. i just start for the training and facing insufficient equipment. Actually what i need to prepare and what i need to take note? And grinding wheels selection is make me confusing.

Hi, I'm working with a Walter Helitronic Power HMC 500 running on WALTER Window Mode that has just been sitting at the corner of the shop and I'm suppose to get it running to resharpen drill bits (both carbide and HSS). Unfortunately, no one here is sufficiently trained on the machine, so it has been difficult to learn everything/find useful resources. I was hoping someone could point me in the right direction as to how to set-up the machine for sharpening drills.

First step is to determine what wheels to buy and what configuration to have. How do you determine what kind of 1V1, 1A1, and 11V9 wheels you should use?

Any help is much appreciated.

Need a few more details on the drills before anyone can give some direction.

How many flutes?
Straight drills or step drills?
Diameter and flute length?
Point type? Standard or Facet?

If it's a simple 2 flute drill with a standard point, all you need is a 1A1 and a 6A2 (4A2 would work as well but you can't dress the inside of the diamond). You can use this setup for facet points as well, but I preferred to use an 11V9 in place of the 6A2

Details on the type of drill are as follows:
- 2 Flutes
- Straight
- Facet point, but I would like to be able to do standard as well
The sample I was given has:
- 1/2" diameter
- 4.5" flute length

For resharpening carbide drills do you simply use diamond wheels of the same shape? I'm also interested if there is a standard relationship between drill size and the diameter of wheels you should use. I've been searching for info for a few days now and haven't found anything explicit.

Thank you for your help

You will want the following wheels to start:

Spindle 1 with a short arbor:
Inside wheel as a 320 grit 4" 1A1 3/8 wide, resin bond, 100-125 con
Outside wheel as a 320 grit 6" 6A2, 3/8" - 1/2" face with a small (.015-.020" corner break) 45deg angle on the OD.

This setup will allow you to run both facet points and standard points with the same set of wheels. Keep in mind that you will need to true the wheels before grinding - especially the 6A2 as wobble on the diamond face can, and will, cause a drill to snap. I can't help with feeds and speeds as I've been out of cutter grinding for a few years and I can't remember what they were. You will also want to use a 'v' clamp with a bushing if you do not want to clamp on the flutes.

The wheel suggestions are just a starting point and over time you can play around with them to find what works best.

Edit: I was going to suggest some wheel suppliers but for a second post decided against it.

I'll have to setup for facet points using 1A1 and 11V9 since there isn't a 6A2 wheel in inventory.

What did you use to true the wheels?

When I was grinding tools, we used a dedicated offline machine for truing and forming the diamond wheels. Here's a link to the machine itself. I believe they will also supply the truing wheels. Going off of memory, I believe that you need the green silicon carbide to do the truing. Double check with your wheel supplier to verify.

This machine saved us a ton of time and allowed us to put fairly complex profiles on the wheels when needed. The only thing I didn't like about it was the vacuum on it - underpowered and undersized.

The 3M Dressing Machine might be a little pricey for our shop, I'll have to see if any alternatives are available. On another note, did you ever dress the wheels with a dressing stick by hand?

Your responses are much appreciated, I'm just an undergraduate researcher for the summer and I've been assigned to get the Walter Grinder operational again. So you can imagine how overwhelming some of this information can be for someone with little experience. Hope you don't mind my questions.

I know that overwhelming feeling. Try making .5mm ribbing tools in a non temperature controlled shop, with no heat exchangers for the coolant, on a Monday morning in the middle of winter (hint: don't try - you won't accomplish anything but add to the scrap barrel).

You need the dressing sticks to open up the diamond on the wheels after truing and a lot of heavy grinding. There will be some resistance at first but then the stick will feed in easily.

You might be able to use a manual tool grinder (ie Cincinnati #2 tool ginder) with a powered work head, just make sure that you match the runout between the Walter and the offline machine. You can also use a small bench grinder and attach it to the table inside the Walter (I don't recommend this if you don't fully understand how the machine operates as you can either manually move the axis or use expert programming).

I hope this helps you along.

How accurate would you say you could grind a standard drill bit?

When I was running the Walters, everything was always ground to spec. Exactly how accurate will depend on what type of inspection equipment you will have available. I've done large tools (6" diameter saws), small tools (0.4mm/.0157"), and everything in between with tolerances ranging from +/- .0001" to +/- .005".

I really miss having the Walters around - the Vision grinder and the Micro Mini are nice machines to work with.

Hi everyone,
I've been a grinder for over 20 years and use Walter HMC 500 with Tool Studio. I work in a job shop, so I see the full gamut of tooling. Occasionally I get stumped and need to bounce ideas off someone. As we know sometimes Walter's application support only goes so far to help. Thanks for reading!

Which documentation do you use for Flexprog. What we have got from Walter is not to consistent. I have difficulties to program the row material measurement. Thanks
