The differance between the two cuts showed very well on video. This is one of the many times were making the tool is easier than filming the results. Nice work, Max.
This is the sort of video that shows if you want a job doing properly, then invest the time in the preperation for the job. Quite often the preperation can take longer than the job. And thats not just when machining metal, it applies in all areas of life. That was 21 minutes of my life well spent on learning about about grinding slotting cutters. Something I hope to be using soon on my new to me milling machine that came with a slotting attachment.
max im in the US self taught machinist with much to learn, your videos like this one are extremely helpful to me and others im sure. you do one of the best jobs on videos and you seem to be a excellent very knowledgeable machinist just want you to know how much i appreciate what you do. A lot of the other creators dont understand the details are very important and i personally hate when others leave them out just to make a shorter video.
Nicely done Max, the noise the cut makes post grinding tells the story. I need to learn to stop and do it properly instead of winging it with a rough ar$e hand ground tool. I have the gear, I have the knowledge, just need to find the initiative again. Cheers, Jon🏴
Thanks Jon . I have been through those periods & sometimes still do it for a rush job . But i prefer to slow down & take the extra time with no rush & stress when i can , that is what makes the trade still interesting to me ! We are our own bosses in our home shops ( except for the real boss . Hers indoors , you know the one ) ! Cheers 👍
thanks for this i just last week turned a bore and cut 4 equidistant slot to make a part i couldnt get i made a cutt but nearly as nice as yours my tool grinding was helped by this video
Another fascinating educational & informative video Max, you have a real talent not just for the work but in the way you both film & present the details. Your video library will build up into a very valuable corpus of your knowledge & skills, not at all unlike Tubal Cain (Mr Pete, our shop teacher. You deserve your success Max. Keep it up, there’s a lot of us out here that appreciate everything you share. Your channel will grow exponentially because of the detail you go into but also because of the variety of jobs you do, there’s always something interesting going on. 👍👍👍🇦🇺
G'day Max. This was a very informative video, with the various angles that you have formed to do the job. When you said broaching, I envisaged a broach with a spacer. Well done .
Great. I have a tool and cutter grinder but I am very much a novice. Great knowledge learned today. Question. Those fine 400 grit and 1000 grit honing wheels. Can you explain more what they are, what/how they are mounted on (realise it is magnet held) and where I can get some wheels, holders and hub. Thanks. Bob
The lapping discs are just a steel disc with a light diamond coating . Cheap & from ebay , made in China & work very well . I have 400 , 1000 & 2000 grades . The holder was just knocked up from scrap & i just run them at a low speed around 200 rpm .
Thanks. I will follow up. Magnets look like they were pressed/glued into the faceplate - right/wrong? What do you run the faceplate on that allows you to keep speed down to 200rpm?@@swanvalleymachineshop
@@bobhudson6659 Yes , the magnets are super glued in recessed holes . Just running it in an old lathe at the moment until i make up a slow speed grinder . The dust will destroy a lathe , so have to be careful .
Have you tried using a smaller rake angle or maybe just kissing a small land on the dead sharp corners? My experience is too much rake will only work good at a very specific feed step. Also both too much rake and secondarily too high of a clearance angle can increase the tendency to chatter, when they exceed what's reasonable for a "sharp" geometry for the workpiece material
What i have found in the past if i use a high rake , it tends to reduce the tool flex . There is a sweet spot where the tool does not try & dig in and also not push off due to high rake . keyway broaches are a classic example , The good brands like Marlco cut properly where the cheap crap ones can dig in . Thanks 👍
Interesting and informative video. I see that you are using a diamond wheel as the main wheel for stock removal. What grit is that? Internet wisdom(!) says that you shouldn't use diamond for HSS - you clearly show that this is not the case... and I know who I would trust...
150 grit wheel , sold as CBN Diamond . Cheap & from China ! I am aware that diamond is not recommended for HSS , but at the end of the day it works . The main reason is heat effect on the Diamond , but keep the wheel stroke short & it's ok . As far as wheel degradation on leading edges , i have found it outlasts aluminium oxide & silicon carbide wheels . But the main reason is as far as i am concerned , it is a way safer option when used in a tool & cutter grinder . The standard cup grinding wheels are very fragile & in a T&C application & you have to think about that when your head is in close proximity ! 👍
150 grit Chinese Diamond CBN . Works well . More suited for carbide , but if the cuts on HSS are short the diamond particles don't heat up & degrade . 👍
Great instructional video. I must use my Harig tool and cutter grinder more rather than hand grinding! One question- do you have a square holder in your mill? I have sguare 5C holders but my mill uses OZ25's which do not have in square profile.
Max, was that hand ground (meant for steel) tool you showed, was that made BEFORE you had the cutter grinder? I ask cause that was the way were forced to make our own high speed cutters back in the day on the pedestal and/or surface grinder.
Yes , before the cutter grinder was working . Even before the Bridgeport was wired up . Before my YT days even ! I had to hand slot some square holes with the Bridgeport in the boring bar to be used to bore my back hoe swing trunnion . Did it in the lathe . 👍
150 grit . A wheel sold as a CBN Diamond from China , that works well . Not sure why they combine the name , CBN & Diamond are two totally different wheels as far as my limited knowledge goes on them . But they work great , Go gentle on them with HSS as they do not like heat but they mow away carbide no worries ! 👍
If i was to say to you: Sid James, Kenneth Williams, Charles Hawtrey, Joan Sims, Bernard Cribbins, Eric Sykes, Kenneth Connor, Hattie Jaques, Barbara Windsor, Bernard Bresslaw, and Jim Dale. What would i be thinking of, Max? How about if they were all still alive, and made a comeback? Another clue, Carry on Slotting. Wouldn't that be a great title for their new film, right? I wonder what the theme would be though.😉 ooo matron. Oh don't, stop it, please don't. Giggle, giggle, giggle went Barbara. Sadly, they have all pased away apart from Jim Dale MBE who was born on 15/08/1935 aged 88 and living in Rothwell, Newhamptonshire, England. What has this to do with this video? Simple, you came up with that title 'Carry on Slotting'😂 You can tell I've had too many beers tonight. Time i got some shut eye. Night night all. 😴🏴⚒️
God but we machinists are miserable gits... not grinding the rake and clearance angles to "save" a stick of HSS despite knowing we can use it regardless.... I have done this so many times its not really funny ... but ...😂😂 😎👍☘️🍺
That shows up great Max. Thanks for taking the time to share the fine details. Thanks for sharing.
No worries , Cheers 👍

Thanks Rusty . Cheers 👍
Thanks for the lesson Max …. Cheers Mate 👍😎👍
No worries 👍
Another very interesting video, thank you for sharing, I'm learning different sharpening methods.😊
No worries 👍
Fantastic Max, there's something special about the sound of the tool cutting. Nice and crisp 👌
Thanks 👍

G'day Max, nicely done mate, looking forward to seeing the machining video too
Thanks Ralfy . Have got some good ones coming up ! 👍
Nice sharp tool you grinded!!!
Thanks 👍
Another awesome video.
Thanks 👍
very good job friend Max..thanks for your time
Thanks 👍👍👍
Enjoyed the discussion on the grind
Thanks Chuck . 👍

Yes 😊 thank you
Like to see more like this, maybe some about the grinding tooling
No worries 👍

Thanks 👍
no flex anymore with the new tool, well done !
cheers ben.
Better than a bought one !!! Cheers 👍
Thanks for your time and talent!
No worries , Cheers . 👍
Super informative for me. I need a tool and cutter grinder..... Thanks Max
Thanks 👍
nice work thanks

good idea 👍
Thanks 👍
Nice grind!
Thanks Don . 👍
Max your camera work is really good.
Thanks . As we both know , it's not in our wheel house & can be a struggle ! 👍
I like it, I can do that on my surface grinder. Thanks for the information.
No problem , now that you have fixed the handle ! 👍
@@swanvalleymachineshop ground some stones over the weekend and it worked great.
Max I can hear clear the sharp and crisp shearing of the cut👍
And that is saying something because I am tone deaf.
Thanks 👍

I sure appreciate how you share the details of every part of this process. Max, did you make your lap yourself? Works great. Happy New Year! TB
Thanks . Yes , made from scrap . But the wheels are cheapies from China & they work well . 👍
@@swanvalleymachineshop That’s great and will be a great project for me. What is your Chinese source fot the lapping disks?

I should have thought it out more. Thanks@@swanvalleymachineshop

How did you hold the tool in the mill? 20:40 looks like an ER chuck with an abour? in it? Nice work Max, crisp😁
Just with an arbor that has a blind hole with 3 grub screws & er40 collet chuck . 👍
Good work max
Cheers Mate . 👍
Is that a CBN wheel and if so what is the wheel grit size ? Thanks for the video
