Awesome. Thank you for sharing. I’m constantly amazed at the complexity of work modern machine tools can produce. Imagine the work that would have taken a manual tool maker to produce just one end mill.
It is just nice seeing you step through such complex processes with ease, like playing a difficult instrument. Thank you for including the programming and thought processes that go into this kind of work, for many of us wierd folk, it is very interesting!
Peter, Thanks for sharing your skills and trade with us! I believe your channel, (you) have raised the bar for RUclips machining videos. I would consider you a Toolmaker due to the degree of precision and accuracy you work to. Half the battle is anticipating what is likely to happen to a material as a result of the subsequent machining ops. This only comes with the proper training , experience and imagination. It's a pleasure to watch your videos !
Thank you for shearing these "spesical tooling" videos. Great explanation everything how, why and from that I know what not to do. Not doing these, but anyways.. And again THANKS FOR SEARING !!
I’ve taken to listening to your videos as a kind of ASMR as I work on my artistic projects. 😄 I watch your videos and pay attention as well but for some reason i can listen to you talk for a long time.
This was very cool to see.. and nice to see the programming aswell.. great video.. Your knowledge beats most people.. always an enjoy and always learns something new..
Another awesome video Peter. Keep up the great work. A machine like that would be amazing to have at our work because we get custom endmills made up for our spline cutters we use to cut splines on all the shafts we do. We get SEI Carbide to make them for us in a 2 mod, 2.25 mod and 3 mod spline profile at a cost of about $140AUD each.
Yes it is nice to have the capability to grind you own tools. It changes the way you can approach jobs. as to the economics of owning your own machine I'm not sure. I think its more economical to buy the from someone else unless you grind many tools. But there is the time it takes to wait for another shop to do it. Also if you can do it yourself you don't have to stock as much extra tooling in case you break a tool.
Yep thats very true. While we do keep about 60-80 of them in stock because we use them daily its probably not enough to justify buying a machine like that. Sure would be nice to make custom tooling though to give you more options on how to make a certain part.
That looks like a really good software package with that machine. It sure is a nice piece of equipment too, looks a lot faster and better than doing all that on a #2 tool and cutter grinder by hand.
work of art making works of art... ruclips.net/video/MtLAn1Ud_U4/видео.html www.star-su.com/machine-tools/tool-sharpening-machines/tool-cutter-grinders/PTG-6L Engineered to manufacture complex cutting tools, the new Star PTG-6L is a five axis, CNC controlled cutter grinder for manufacturing, sharpening and reconditioning a wide variety of cutting tools. Made in the U.S.A. and equipped with a six-station wheel pack changer, the PTG-6L is built for high productivity and precision.
That's very cool! Hope there is more of this kind of tool grinding videos coming. And could you please explain the nomenclature of the endmill, like what is primary relief, gashing...etc. Thanks!
Thanks! I meant to show in the video but forgot. When the machine is running you see no code scrolling by. All these cycles are run in some kind of canned cycle so all you see is something like G330 and that’s it. Now imagine how complicated that is to do full five axis moves with grinding wheels and offsets.
Yeah, pretty sure the machine doesn't run on normal G-Code. Or essentially it's a bunch of hidden G65 Macros of some kind. All the settings you fiddle with are a bunch of 'go' commands, and every motion generates itself due to, in some form, already written. ;) If you decided to attach some wheels to your Mazak spindle for some job. The amount convoluted workarounds you would be needing to do the software, and offsets will be nuts.
very interesting, that cad/cam is that software just for that tool grinder? interesting seeing the touch off and if you took tool out and then put tool back in it can reset flute location with the probe, what does the Aloris tool post do in the machine?
Yes the probe can relocate the flutes. You can even measure the helix angle and measure uneven flute spacing. If you watch my video Modifying a micro 100 tool you will see what the tool post does. Thanks.
It kind of depends on the size and tolerance. Any ware from $70.00 to $200.00 for a 3/8” size. Also it depends on the complexity of the shape and coatings if any. I have made tools that went for more than $500.00 for just one tool. So it depends.
Thanks for the reply! Thats actually really reasonable! I wanted to get some custom Onsrud like O-flute bits made with longer cutting edge, something like 3/8" shank with a 2" cutting edge for the deep pocket reservoirs i make on my cnc router.
The principle is good but you don't realise the limitation you place on yourself by using the "flat" surface of a belt grinder. Using the round surface of a grinding wheel and placing the drill bit against the wheel ABOVE the centre of the wheel "automatically" grinds in some back clearance angle. A little like a ".hollow grind". Doing it in this way you have enough room at the end of the drill bit to grind a nice "facet" on the cutting edge. (The movement of the drill bit is more or less the same though). When you have finished grinding the cutting edge a very slight "tweak" to thin out the web provides a nice "point" to catch in the centre punch mark. AN advantage of the "facet" is that it makes it a little easier to see if the cutting edges are equal. Regards Peter
That's really cool Peter. Today I sharpened a 2 flute 1/2 HSS on our cuttermaster grinder for the first time. It's a far cry from what you're doing for sure. Is that software unique for that machine?
As always Peter, great video and great explanation. Does the offset (what you changed from .005 to. 002) offset the wheel? Bigger wheel, smaller tool? Also, I noticed the little drawing called out 3fl, did they get an extra for free? Lolol, just funnin', I know you said you knew the customer and the tools purpose. Take care!
I talked to the customer and asked if I could make them 4 flute tools. The reason is it’s easer to measure the diameter. The offset I changed is for the face of the cup wheel on the end of the arbor. This is sort of like the height offset on a milling tool. You can assign the offset either to the diameter of the wheel or the flange distance of the wheel on the arbor (the length from the spindles face). Thanks.
Edge Precision That's a great reason, and you're absolutely correct about it being easier to measure. I meant no harm/offense with the comment, I love your work and your channel. Thanks for the reply, and explanation of the offset!
How did you run without coolant? You mentioned you had to run coolant, so you closed the doors and the coolant came on, yet you have shots without. Did you only run coolant on the steps that absolutely had to have it and dry on the rest, or did you cut another tool dry just to get video.....I'm not sure if you could run dry and sacrifice some stock and a bad finish, just for video sake. Great video. That finished cutter looked like an art piece and it is cool to finally see how mills are made. Maybe I missed it, was that tool cut from carbide or was it some form of steel, such as HSS?
If you watched & listened after he closed the door for the coolant, he explains that he's doing a dry run just so we can see what's going on. The dry run happens with an already ground piece of stock, so the wheels don't need to grind much/any material without coolant.
I first ran the whole tool with coolant. Than for the video I reran the program without coolant wile recording the video clips. I actually had to run it twice to get all the clips I wanted. If you look at my latest Intsagram (peterlstanton)post you will see all the tools I ground for this customer. This was just one of many.
Hello Peter thanks for the info you provide. Question can you make any type of tool or is the tool grinder just for special type tools! That are not available inexpensive, I hope my question makes sense.
If you mean can it grind standard tools. Yes the cycle I use in this video is for grinding a standard endmill. I just changed some settings to accomplish a custom tool. This video just shows a very little what this machine is capable of grinding. With proper fixturing I have ground or modified lathe inserts, brased tooling, reamers, form tools, corner rounders exc. With the proper shaped wheels it could grind thread mills and taps. The only limit is the operators ability to do it. I have had no training so I’m still learning.
Edge Precision ok. So this machine is what an actual tool making company would have to produce their non insert tooling or a machine similar. Cool thank you.. I would truly enjoy apprenticing for or with you. I have no manual or cnc experience but I have metal fabrication experience custom sheet metal and trailer building. I am fascinated with metal work and mills lathes and cnc. Thank again
Thank You. I did do something similar to that. I used Acetone I didn't have any alcohol. Even the moisture coming out of the air hose shows up. Than you try to dry it some how and I couldn't find anything that wouldn't leave lint. I even tried spraying it with RainX than blowing it off. On the toolsetter (The CNC one) we use this sticky stuff to remove the lint and dust because it will pick it up as the tool when making a measurement. But I couldn't find any at the time I made the video.
A grinding wheel pack with the three wheels like yo see cost about $1200.00 for the three wheels. These wheels have a lot of diamond content. They are not the same as the type you typically use on a manual tool and cutter grinder. Oddly CBN wheels for grinding HSS cost even more than diamond.
Many years ago I was doing some parts called battery inserts. In the oilfield these parts carry the batteries for their down hole instruments. They are usually made out of Inconel 718 for some reason. Doing the end work on the horizontal mill requires many special form tools for the ports. I started by having other grind shops making my tools but they didn't get it right or my design didn't work the first time. It requires experimentation sometimes. Well I had so much difficulty with that. I kept my eye out for a good used CNC tool grinder to make my own tooling. One day I say this machine for sale and bought it. Than began the learning challenge/ordeal of knowing nothing about grinding tools except on a manual too an cutter grinder. The terms and grinding cycles are totally different than normal machining. But I did learn and this is where we are today.
If you mean how long would a tool like this would take. Less than a hour start to finish. It takes quit a bit longer to record video and make the tool. Thanks.
No just special tools. The big tool companies but high quantities of carbide and have their own coating equipment. They also have many machines grinding tools all at once. I can’t make standard tools for less than they can.
Hello I have 1 question. You changed length of rod on 0.1 inch I understand why. I did something and simulation was OK. If I wanted to make tool like this my machine doesnt count with that. Could you write me where can i rewrite this value for NC machine? Thank you for answer
In the manufacturing menu you need to select shorting the tool by the amount the tapered tip sticks out in front of zero. (In this case it was a little less than .100". So I used that.) But if the setting in the probing setup is shorter than that it wont let you enter the .100" shorting in the manufacturing setup. You need to increase that to something greater than the value you set in the manufacturing setup. This is only necessary because the tip of the tool is greater then the blank. Or more precisely greater than the software thinks it is. I am forcing the software in this case to do what it isn't really setup to to. But it will do it.
In response to "Hey You" After 40+ years in the industry you should be able to sharpen drill bits in an instant "with your eyes closed" It's certainly NOT a difficult task. It takes only seconds to sharpen a drill bit, certainly less than a minute to sharpen a DULL drill bit and not much more time to sharpen a damaged drill bit! I can sharpen a dull drill bit in less time than it would take me to go to the cupboard and unwrap a new one!
How amazing you have one of these machines too! Last week blacksmithing this week grinding custom tools on a cnc grinder, my favorite channel!
Awesome. Thank you for sharing. I’m constantly amazed at the complexity of work modern machine tools can produce. Imagine the work that would have taken a manual tool maker to produce just one end mill.
It is just nice seeing you step through such complex processes with ease, like playing a difficult instrument.
Thank you for including the programming and thought processes that go into this kind of work, for many of us wierd folk, it is very interesting!
As I watch this It appears simple and obvious while at the same time I know it is neither simple nor obvious! Very interesting work, Thank you!

Wow! What an impeccable job. Thanks!
Thank you, Peter.
The programming demonstration is excellent!

Interesting video, thanks! Would wiggling the part in a small glass of ethanol then blasting it off with air not take off all dust and particles?
Thank You. I did do something similar to that. I used Acetone I didn't have any alcohol. Even the moisture coming out of the air hose shows up.

Edge Precision Ah ok blue tack (or something like it like Play-Doh)? I had no idea that it was so critical when using a microscope...
Great once again, from someone who doesn't know anything about grinding. What price range and life are you looking at for these wheels?
A grinding wheel pack with the three wheels like yo see cost about $1200.00 for the three wheels. These wheels have a lot of diamond content. They are not the same as the type you typically use on a manual tool and cutter grinder. Oddly CBN wheels for grinding HSS cost even more than diamond.

Quite the story! Super cool!
For example , how much are you charging for the tool ? , just out of curiosity .
how long time did the piece take to get it finished
love ya
If you mean how long would a tool like this would take. Less than a hour start to finish. It takes quit a bit longer to record video and make the tool. Thanks.
Marvelous! What is the carbide blank you use?
Thank you. I buy my carbide blanks from a place called Centennial Carbide. I usually buy their Ultra micro grain Blank when possible.
Is that an air-bearing spindle?
No it runs on ball bearings.
I am trying to sharp conical ball end mill with the taper of 8.840 degree, but unable to generate program in speedgrind pro.
I’m sorry I now nothing about speedgrind pro. Otherwise I would try to help.
Do you grind all your end mills? Is it cost effective?
No just special tools. The big tool companies but high quantities of carbide and have their own coating equipment. They also have many machines grinding tools all at once. I can’t make standard tools for less than they can.
19:24 for grinding only
love the video....but a lot if noise in the sound ( understandable)
Yes thank you. I am trying to think of ways to minimize this. I am recording this in a functioning machine shop. As you say understandable.
Hi sir am interested on your video. How can I contact you
Hello I have 1 question. You changed length of rod on 0.1 inch I understand why. I did something and simulation was OK. If I wanted to make tool like this my machine doesnt count with that. Could you write me where can i rewrite this value for NC machine? Thank you for answer
Are you using the same NumRoto software that I am?

Hi, Master!!)
Very intresting!
Im use ANCA and Rollomatic machine vith experience to grind 20 year incl simple cnc.
Put Like and follow after u video
the video is black on my screen, i can't see anything
