Mastering Carbide Drill Grinding With The Incredible Walter Helitronic Power 400 Top Loader

[@Philiamq]

Great to see a full tutorial from start to finish on these amazing machines, we need more people learning how to use them! Great job Chris, enjoy these Walter videos a lot! 💪🏻

Thanks for the support!!

Great info Chris. It's hard finding this level of content, yet alone, for free! 👏👏

I work where we have 9 Walter grinders and 2 Walter Erosion machines. 2 have the top loaders. The Tool Studio software is amazing. We have approx 40 wheel packs across all machines. We are a Regrind shop and have wheel packs very similar to the ones shown here. We do torque all the wheel nuts to a certain Nm. Keep up the great work!

Great video Chris. That machine is amazing!

[@donniehinske]

It’s insane to me you can stack those wheels so close like that and there is still enough room to make tool bits in that machine! Good video Chris!

[@TheDandyMann]

This is what my company does and what im an apprentice for. We have so many wheel packs all ready to go we have laminated tags for them. I introduced them to cat 40 tool tags for easier visual reference to be more in line with their 6s goals

Thank you for this informative grinding video, Chris! It’s cool to see how the tooling we utilize on a daily basis is manufactured. 🙂

[@CatNolara]

Very interesting, always wondered what the process of tool production would look like. One question, how does the machine know the geometry of the grinding disks? Are the disks and spacers made to really tight tolerances or does it get measured and adjusted during setup? Do the grinding wheels need to get dressed or how do you deal with tool wear?

[@christophervillalpando1815]

You measure your wheels and input that data into the software. You need to dress in your wheels as they come close from the factory but dressing them in would make them perfect as well as eliminate any runout.

[@CatNolara]

@@christophervillalpando1815 thanks for the insight. How do you even dress diamond wheels?

[@ericsandberg3167]

I'll bet it took many hours in the classroom to learn how to program this Walter machine....the end results are impressive.

[@axkev1_22]

You need to show all the nasty sludge it makes during the grinding 😂

Thank you very much for this new very instructive grinding video. Special thanks about Tool Loader configuration, it's a very precious information. I have some questions... - There is no need to tightening to a target Nm value with a torque wrench for tightening the grinding wheels on the grinding wheel holder ? - You can mount grinding wheel pack on the grinder "directly" wihout balancing the wheels pack ? Hope start this year in CNC grinding trade (the machine will most certainly be a second-hand Walter Helitronic), if i can avoid to invest in the beginning in a wheels balancer, it's a very good news ;-) I hope you will continue to create tutorials videos on the Walter like the installation and configuration of the grinding wheels on the machine, for the moment I have not found this information anywhere. Thank you again for sharing all this information and skills. Chris.

[@christophervillalpando1815]

It is always a good idea to balance your wheels before loading them into the machine. An unbalanced wheel can be a train wreck waiting to happen. I would invest in a measuring device to check runout and a wheel dresser. I dressed my wheels and verified the runout in these wheel packs. The balancing of the wheels, dressing them and runout all tie together. A wheel balancer would be a very advisable purchase if you are looking to get into grinding. As for torque specs refer to your machines manual, as it varies throughout.

@@christophervillalpando1815 Dear Christopher, Thank you very much for your answer. Noted about balancing the wheels pack, it's not an option. I look forward to your next videos regarding the use of the Walter CNC grinder ! Thank you again for everything you do @ Titan of CNC. Boom! Nice day. Regards, Chris.

Badass! 👍

I want 0.65mm carbon endmill with 0.1mm corner radius ...flut length 2mm parallel length 10.5mm(i want to mill mm straight deep milling ) and.....shank 3mm

Is nobody going to say something about the comfortable gaming chair they have on the background?

[@shaniegust1225]

😂

[@stefanivanov8587]

So did you balance the wheels or not and my other question is does it handle well custom tool making with bigger diameters because usually I do custom tools on Schütte 335. but there is no lights out option.

[@DavelyDriven]

So runout is de-concentricity….essentially?

[@hokkypro]

I didn't quite catch the name of the machine, what was it?

[@n.b.p.davenport7066]

I have all that stuff

[@1AB09CC3]

Why do you need to probe the flute location? I mean they were just ground in the same setup, so I don't get if it's really necessary or just a double check. Full disclosure: just a lathe guy :)

[@ryanjordan7113]

It’s probing to offset the next wheel/tool with a macro so the controller knows exactly where to start. Also if the work truly has been cut; in order to make sure it has clearance for the subsequent path. There is what’s called a variable macro B code. If the probe reads outside one of these variables the programmer sets. The machine will not run the next path.

[@1AB09CC3]

Thank you for the detailed explanation
