- I showed a photo on Instagram of sharpening some drills. Some people asked if I could make a video on the process. So here is the video.
My Instagram is Peter L Stanton
Another fascinating and informative video, thank you for taking the time to make them.
Looks like you get a bit better results than I do eyballing it with a bench grinder.
Thanks for being so generous with your time .
Hi Peter another well explained and informative video. During my apprenticeship in the late 1960s and 70s,we did a stint on the tool& cutter grinders. We had Cincinnati and Jones & Shipman both good machines. The cnc machines of today are marvellous pieces of kit, how I wish I was an an apprentice now. Keep up the good work. Regards Paul UK
My work bought a used Star machine a few years ago. It sat a long time. I come along and have been learning it as we go. No instruction manuals at all lol. Its a very enjoyable machine when its working correctly. We are sharpening Gear shaper cutters, and trying to get it to grind hobs.
Yes Star kind of specializes in grinders to make and sharpen gear cutters and hobbs.
It is amazing how big is the range of maschins in your shop. You can do almost everything. Thanks for your videos!
Interesting as always, thanks for going into detail on the probing.
Business question if you dont mind: Would you buy a new (or used) t&c grinder, if this one died beyond repair? Your line of work seems to require custom tools quite often.

I the past I used this machine a lot more than now. And then I did look into buying a new one. These machines new tooled up are very expensive. One this size would be in the neighborhood of $600.000 dollars. So at this time I would not buy another one if this one died. If I was younger this is my thought about buying machines for busness/making a living. I would always buy new if the busness plan could justify it. Because you have to depend on the machine working consistently. So to have a warranty and quick service is paramount. Also you have the latest technology to be competitive in industry. All my machines I currently own (except for the ones in the garage) I purchased used. They are all around 20 years old. So if something goes wrong it could take time to repair. But at this time in my life I could afford this time. But if you are running a busness with employees. Your most expensive cost is labor. So the new machine is the best route. I don’t know in your country but in the USA there can be certain tax advantages to offset the extra expense of the newer machine. Kind of a long response but this is a rather quick answer to what can be a complicated decision. Depending on the busness situation.
@ Edge ?.
Beautiful response.
At that price for a new machine you would have to have a lot of work for it to be worth the investment.
@@EdgePrecision Thank you for the answer - makes a lot of sense.
I had no idea how the coolant holes in carbide drill blanks were formed, fascinating stuff!
Add to that I had no idea how the carbide blanks were made
Thank you for explain it in calibration on your tool cutter grinder I know you’ve done cutter grinder videos before and I’ve watched every one of them and I find it very interesting and technically informative.
It would be nice to have access to a machine like that.
Thank you for the tour! I had a learning experience with some 4130 that work-hardened on me and now I have some more work for such a machine.
It is awesome having a machine like that at your disposal.
What an amazing machine! Thank you for the presentation.
Look up anca fx7 or Walter hmc 600. Have fun.
Thank You Peter for showing how to do these important measures so well!
Hello Peter, thanks for all of your videos!
Watching you doing all the different stuff is kind of relaxing me and thinking about the things I wanna do at work.
I like your way of showing real work, not the badass thing of machining with no problems, this is very boring and shows not the reality.
I'm kind of bored from all the companies I worked for, most of them are working the old 84 way, calculating all points and programming by hand.
It's a wonder how they can exist on the high end german market with this attitude....
By the way, tool sharpening is really interesting, i would like to have the chance of learning it by my self too.
We often customize inserts by using wire EDM, its good for a lot of tasks but be able of cnc tool grinding is on of my goals in life, thank you for showing some little aspects of it.
Shooey that's some old software bud. Great video love learning new stuff from you
Thanks for showing us this! I hope you have a great weekend.
Hi Peter. I just want to thank you for sharing all this knowledge. As a new machinist, all the info you share with us is invaluable to me. Thank you.
May I ask how you organize all your tooling inventory? I'm having some trouble keeping track of all my tooling at the moment.
If you want to organize something than you have to have three piles a keep throw away and maybe keep. After that put duplicate tools in same place as each other and don't forget to put them away which will make you lose them and have to buy more which isn't good or if you are only one working at the time keep a logbook of what tools you got out of the tool room. Like my teacher said if you have a clean organized tool room you should be able to tell someone exactly were a tool is.
Cool information on the helix on the drill I wondered how they got the holes in them for a while
I didn't realize the coolant holes follow the helix. That's wild.
very good job peter...thanks for your time
Very informative. Thanks for taking the time to share this.
Thanks Peter for the video. Always very informative and explained in a calm manner. Interesting to see that the tool probe it self has the ball zeroring position. I would have expected the tool probe could have done the zeroring on the reference position, so very enlightening to have that explained. Regarding the Windows XP, don't worry if the computer gives up there are new computers that can have Dockers installed and then XP operating system op top of Dockers as a virtual machine. Then the application program, can be installed in the virtual machine. Do not scrape the grinder because of XP is outdated.
The sphere/ball under the probe on the spindle is for calibrating the grinding wheel probe. The square block above the collet chuck is for the tool probe on the spindle. I wasn't to clear about that in the video. As for the computer. The machines control is actually in the back cabinet. Star grinder make new grinders. Also using NumRoto software. I'm pretty sure they are running a newer version of windows on them. They probably could setup a whole new computer to run this machine. But I would be a little costly having to upgrade the software to the newest versions. That's where the cost would be.
Thank you Peter!

Thank you Peter! Very interesting.
Very interesting, thanks for the video!
May I please come visit with a bunch of drills that need to be (re)sharpened? That expensive machine has paid for itself. Probably many times. As always: another great informative video.
Wow - super interesting Peter!! God Bless.
Interesting stuff. Thanks for showing this...
Basically drooling, I'm just happy that it's a skill I have tried to actively keep up since my apprenticeship, okay, it's just twist drills, chisels etc but still!.
Nice. I thought for some reason they did tool grinding by hand. Lol. Makes it way easier. Thanks
Ahhhhh, the Crayola Windows XP theme. I had a massive laugh earlier this year when a younger software dev had to do some work on an XP era machine and complained that they couldn't find anything. 🤣
"Although I've never ground a bur before I could do it technically" I feel that statement
Imagine making tooling under .050 But ultra small work has been done for ages, think watches and stuff like that. Someone's got to do it.
Thanks for taking the time to make these videos. Very cool machine - What does a machine like that cost?
Wish I had one.
what is the max acceptable drill run out? how do you check it and how do you adjust it? Is the machine dealing with it by probing? Thank you for your time!
I didn't show this in the video. But I indicated the drills to less then .001" of indicated run out before grinding. It can be done by lightly tapping on the end of the drill with something soft. Like a piece of brass or aluminum. The probing has no effect on the run out.
👍
this was so cool to watch. Does the oil that machine uses as a coolant smell funky at all? it looks so thin volatile
No it is special just for this purpose. The first oil I used in this machine was called Carbogrind it was thin just like water. It was an excellent grinding oil. But I was very sensitive to it. It would give me a rash like poison ivy. I had to change to this oil. It is made by Hanksterfers. But I think they no longer make it.
@@EdgePrecision interesting. I only learned about the world of CNC as a decade ago I was a traveling salesman selling industrial chemicals (mostly cleaners) and our company bought a cnc coolant company and they wanted us to start selling there stuff that they claimed was less likely to cause contact dermatitis. So I spent a lot of time in machine shops talking to guys that get dermatitis from their coolants and I was surprised how big of issue It really is
Hey Peter, can you regrind OD of flutes ? Like say, 6.5 mm from a dia 7 drill ?
Yes that is possible up to the shank. But this machine isn’t really setup for cylindrical grinding. I would regrind the flutes with a slight clearance angle. That’s what I usually do when making special size drills.
Wat kind of probe is that ??? That’s a beautiful finish
This machine has Marposs probes.
@@EdgePrecision I been grinding braze carbide tools manually..this machine is amazing
Good afternoon; I currently work in a steel making facility and was needing some more information if possible about this machine/process.
I have other videos on my channel about using this grinder.
Use magnetic Windows cleaners to clean plexi shield
I'm not sure what that is. And why it would work. The even if the window was clear there is so much coolant you cant really see the tool anyway.
Save money in the long run..
✋🏼🇦🇺👍🏼
At first glance, this machine seems redundant, at least when it shows how a simple drill is sharpened. It is especially surprising to watch this from Brazil - here even in tool stores there are only drills with a pitch of 0.5 mm. And I think that on the simplest CNC router I can make mirror surfaces of the cutting edges with a diamond bur, I will rearrange them by 180 degrees with my hands.
PS I saw the price. I thought a lot.
Oh the audio, right off the bat. You could do a little better on audio, video and contents good though. But Who am I to judge, I'm just a dude without a lathe, mill, or cnc. Lol. As much as I'd like to make my own, having parts machined in Hawaii (mainly my xy sleds) is expensive, even when you have a big boat to bargain discounts and can do your own CAD work.....
This is a very difficult audio situation. There are many machines running all around me. Not to mention the one I’m running. Air grinders, people blowing air guns. I’m filming in a working machine shop. I have tried to put filters on the sound to reduce this noise. Then people complain about the sound as well. Because it distorts it in another way. I get even more complaints.
@@EdgePrecision i completely understand your situation. It was an audio jump at like 17 seconds in... either way, wasn't trying to be a buster about it, it was just that one clip right off the bat that made my headphones jolt me a little. I am a content creator, just on a different account for a hobby, but I think most programs can show your audio levels so you can see those big variances between clips like that. I enjoy your footage though.
And to be clear, it wasn't background machine noise or shop noise, it was voice audio from one clip to the next. Id be a fool to complain about background machine noise on a machine video.

Why do machine shops put 4ft-6ft of concrete?
Are you referring to under machine bases?
@@EdgePrecision Yes,I heard it keeps it from tapering
@@lonestar9453 yes a foundation gives more weight and stability, rigidity to the machine. Although they are not usually that thick. The one under my Mazak is around two feet thick. Under the Mitsubishi horizontal mill about three feet. This grinder in this video did not require a foundation. Because of the way the machine is built.
Hi sar please help me numroto plus software dawonlod
Clear as mud !!!! 😖
7 mins to sharpen up a drill bit? better be an important hole youre drilling
