Grinding a Step Drill on the Walter Helitronic Vision 400L from United Grinding

[@sergeidragunov8103]

As always, Tight... nothing beats having the right tools and equipment!!!

[@joycethomas8868]

Always thought Walter grinders were the best. This guy did a great job demonstrating the grinding process, use him more in your videos. Cheers

I got to run one of these Walter Vision machines for a short time before retirement having previously ran a Walter Micro for several years along with a Rollomatic 620XS. Having spent 20 years in either manual tool grinding(6years) and (14 years) as a CNC Tool & Cutter Grinder running Anca’s, Rollomatics and Walter machines, I must say running the Walter Vision was a joy. Once the Vision was warmed up you could run hours and hours on most jobs that were programmed right with a tenth or two tenths offset change for 100-200 tools. Moving a tenth got you a tenth. Amazing machine. We had that wheel dresser too. So easy and great to use. I also spent 15 years as a CNC machinist. The Walter Vision was the most satisfying machine I ever ran in Machining or Tool Grinding. Maybe running parts you could see and inspect more easier than those micro tools had something to do with it also.😀It’s a great machine.

I used to do that on a manual toolpost grinder, pretty cool to see the new age equipment!

[@stevehayward1854]

I used to do this by hand and eye. First grind profile using a grinding machine with a shadowgraph and then cutting angles put on by hand. Lol for that steady rest I used to use a stick

Being interested in technology and how it is achieved is where I come from. These insights into the way things are produced to then make the “bit” someone needs and wants is inspiring to watch and have several lightbulb moments. I can only imagine what the trade is getting from this! I’m just some one who likes to know. Keep it up team Distributing information is just wonderful Keeping information to your self can make you the emperor. Remember empires don’t last for ever. ( Inca, Rome, British, Pusan to name a few) Giving information makes friends. These friendships last for lifetime and the legacy of the information goes on further. Amac

I couldn't agree more. We love the industry and making the world aware of the technology available to make amazing products. We aim to inspire new talent to continue contributing to the future of American manufacturing.

[@jeremyearney6434]

Amazing machines and amazing skill set. Love watching the videos of the grinders. The one other where you made a ball end mill was amazing. Keep it up.

[@senad707]

It’s a great presentation I can’t disagree 75% of it is said except the part of making the program and doing the steps before you start running a tool which requires indicating the blank or indicating the Chuck more correctly and adjusting the steady rest so that it’s holding the tool were supposed to center it basically in the last one is to adjust the cooling lines and the pressure for specific operation, I’m a senior Machinist working on this machines for well over a decade and I can tell you this machines are amazing especially with a new software toolstudio they are much easier to program and run I can’t say that the machines are perfect they have all flaws but from all other CNC grinders Walter is definitely in the top five grinders rollomatic I would say number one saacke number two Walter number three anca number four and vollmer five.

[@xkell9926]

Thanks for details there from your experience, nice to hear about the tool studio and how setup is improved

[@yun514]

I just saw one yesterday and damn I grind everything by hand . I can't compete with this machine I need to learn this to

[@MoksudAli-h7x]

Best part is the software -Tool studio, I made drills endmill profile tools in my 16 years carrier. Walter it's the best machine.

[@Ham68229]

I enjoy these types of videos. I hope there's more videos like this one. Always amazed at how "tools" are made. I'm not a machinist and will most likely ask dumb questions but, gotta learn some how. Cheers :)

[@miguelcastaneda7236]

and to think i still do this by hand spindix ..polychoke and relieve by hand and be done in thirty min and have tool installed in machine

[@metinsaliev9497]

Yeah that's what I'm talking about at least you are the real deal I know what it takes to achieve that skill set for me to freehand a flat bottom takes less than 45 seconds lol and ion the machine making chips in less than two minutes

[@extradimension7356]

Looks pretty amazing !

[@andyvan5692]

great video, and nice to see some wheel setup, PS what lathe/grinder did you use to dress the wheels?, was it the same machine you did the part on?

[@mw8580]

I remember when I was doing my apprenticeship a guy took about a 1mm cut on a surface grinder, shit the life out of me , got blue swarf coming off the bloody thing. I had to dress up the wheel afterwards, took me some time.

[@andrewbeaton3302]

LOVE THIS!

[@jackcanning5087]

What do you do if you take the tool out and a size is out? Will the tool not lose probing settings after it is took out the chuck?

[@mckenzi1984]

Sir, what feed do you use for fluting ?

[@robespierremendes7335]

Amazing!

[@Frankz455]

Dressing the wheels seems to be a lengthy process, i am wondering how many parts can you process before having to re-dress the wheels ?

[@redbeard_1371]

That depends on many variables. Some jobs may require identical wheel packs. When one pack needs dressing, load the new while the other is dressed so there is only a small interruption in the process.

[@parmesanjon]

Couple very general estimates - 750pc 1.5" LOC 1/2" Dia 5 flute endmill. 150pcs 1.5" LOC 3/4" 3 flute endmill. Max we see is 2000pcs on some 1/8" tooling, minimum we see is around 25-75 on some bigger diameters. But these are all general estimates and greatly depend on the wheels and how the tools are programmed.

[@denissorokin8826]

Of course you could grind this tipe of tool without pilling wheels. Only measure diameter, length and corner radius of wheels. And two wheels are enough to make the drill. But for movie its beautiful to show. Thank you) p.s. sorry for my English

[@dieterlahme8604]

Walter, Schunk, Haimer made in Germany. Grindingtools from Tyrolit made in Austria. Booom

[@TITANSofCNC]

Kennametal made mostly in the USA… Blaser coolant made in New York for US. Many products are simply not made in the USA. So, I teach to use the best most efficient products in the world… so you can compete in a global market and keep making parts in the USA!!! Or where ever your from.

[@truthbomb4775]

Wow, that’s a whole lotta money to sharpen a drill bit. 🤯

[@redbeard_1371]

People regrind tools on these all day long. Save and make mucho $$$

[@TITANSofCNC]

From small projects to huge projects… it’s all about bringing awareness to a world that is very rarely seen online.

[@billpiehler9010]

Many shops I've worked for had to send out for regrind or special tool features. Having it in house opens up the possibilities

[@Fabiable]

Help me Step Drill im Stuck

[@GreddyS14]

What are you doing step drill, help me I’m stuck

[@gilloub7898]

How long to grind this tool ?

[@Yu-et1ii]

10-15 minutes tops

[@トミーグローバル]

🤩👏

[@Liviobuffon12]

The tyrolit company advises grinding wheel whit oil not to dry.

[@kevinspacey5325]

Bro, it's Anca team all the way. . . . . edit - You're using rolled relief on that back 45 degree that creates a huge undercut 🤣. . . That undercut will allow a burr to be pushed right back into the I.D. when that drill rapids back out of the work. I really hope you have since moved to profiling. Edit 2 - You showed truing the wheels, but mention nothing about dressing them. 2 very distinct processes. edit 3 - you don't need a steady rest for a .500in diameter tool hanging out by about 1.5in there cowboy. I do much more with my Anca Fastgrind (2013) than you showed here.

[@eddiekulp1241]

Balanced wheel after it was dressed ? Seems wrong

[@tylerakerfeldt7220]

Perfect counter bore or counter sink? Because you won’t get a perfect counter bore with that bevel.

[@DolezalPetr]

BOOM, USA

[@ChannelVariabel]

Same machine and same product with us

[@Anthony-uz5tj]

broke one of these bits today.

[@jasondevault5066]

😱

[@EshanAdithyaJayasinghe]

I am stady good tech

[@metinsaliev9497]

Hmmm nice toy but some of us can freehand hand this tool in less than two minutes and it will be just as accurate.now that's some serious skill could you get it done if your grinder broke down the answer is no

[@Yu-et1ii]

I doubt you could free hand that tool and keep it within a tolerance of 0.005".

[@metinsaliev9497]

Yu no you are wrong five is very generous I can make it cut to size freehand and it is absolutely necessary in my environment it seems you got lost in automation

[@a.k.2023]

Macht nen ganz schönen Parteitag aus so bißchen Stufenbohrer. 😄
